In circle H with m \angle GHJ= 90m∠GHJ=90 and GH=20GH=20 units, find the length of arc GJ.
HELP!!
The radius is equal to the length of the given line segment GH, which is 20 units. In this case, r = 20, and θ = 90° = π/2 radians.
Arc GJ is the portion of the circumference of circle H that lies between points G and J. Arc GJ can be calculated using the formula l = rθ, where l is the length of the arc, r is the radius of the circle, and θ is the angle subtended by the arc in radians. In this case, r = GH = 20 and θ = 90° = π/2 radians. Therefore, l = 20π/2 = 10π. Therefore, the length of arc GJ is 10π units.For example, if the radius of circle H is 10 units, l = 10π/2 = 5π. Thus, the length of arc GJ would be 5π units.To calculate arc GJ, we must first determine the radius of circle H. The radius is equal to the length of the given line segment GH, which is 20 units. We then use the formula l = rθ, where l is the length of the arc, r is the radius of the circle, and θ is the angle subtended by the arc in radians. In this case, r = 20, and θ = 90° = π/2 radians.

In the scale drawing of the base of a rectanglar swimming pool, the pool is 8.5 inches long and 4.5 inches wide. If 1 inch on the scale drawing is equivalent to 4 meters of actual length, what are the actual length and width of the swimming pool
Answer:
34 m x 18 m
Step-by-step explanation:
No picture shown, but we can do it anyway. If one inch on the drawing is actually 4 meters, multiply each dimension by 4.
The actual length is (8.5 * 4) = 34 meters.
The actual width is (4.5 * 4) = 18 meters.
The actual dimensions of the pool are 34 meters long and 18 meters wide.
Compute the correlation coefficient for the following: X: -5, 1, 2, 11. Y: 5, 3, -3, 0
The correlation coefficient between X and Y is approximately -0.483.
We must first determine the mean and standard deviation for both X and Y in order to calculate the correlation coefficient between X and Y.
X has a mean of:
(-5 + 1 + 2 + 11)/4 = 2.25 is the mean of X.
Y has a mean of:
average of Y = (5 + 3 - 3 + 0)/4 = 1.
The value of X's standard deviation is
s_X = sqrt([(-5 - 2.25)^2 + (1 - 2.25)^2 + (2 - 2.25)^2 + (11 - 2.25)^2]/3) = 5.1478
The value of Y's standard deviation is
s_Y = sqrt([(5 - 1)^2 + (3 - 1)^2 + (-3 - 1)^2 + (0 - 1)^2]/3) = 3.7712
After that, we can figure out the correlation between X and Y:
cov(X, Y) = [(-5 - 2.25) × (5 - 1) + (1 - 2.25) × (3 - 1) + (2 - 2.25) × (-3 - 1) + (11 - 2.25) × (0 - 1)]/3 = -7.25
We can finally determine the correlation coefficient:
r = cov(X, Y)/(s X, s Y)=-7.25/(5.1478 3.7712)=-0.483
Thus, roughly -0.483 is the correlation coefficient between X and Y.

Brian has $20,000 in a savings account that earns 5% annually. The interest is not
compounded. How much will he have in total in 5 years?
Answer:
Since the interest is not compounded, Brian will earn a simple interest of 5% per year on his initial deposit of $20,000. The formula for calculating simple interest is:
I = P * r * t
where I is the interest earned, P is the principal (initial deposit), r is the annual interest rate as a decimal, and t is the time in years.
Substituting the given values, we get:
I = 20,000 * 0.05 * 5 = 5,000
Therefore, Brian will earn $5,000 in interest over the 5-year period. Adding this to his initial deposit of $20,000, we get:
Total amount = $20,000 + $5,000 = $25,000
Therefore, Brian will have a total of $25,000 in his savings account after 5 years.
Answer:
$25,000
Step-by-step explanation:
The total amount Brian will have in 5 years can also be calculated using the formula for simple interest:
A = P(1 + rt)
where:
A = the total amount
P = the principal (initial balance)
r = the annual interest rate
t = the time period (in years)
In this case:
P = $20,000
r = 0.05 (since 5% is the annual interest rate)
t = 5 (since we're calculating the total amount after 5 years)
Plugging these values into the formula, we get:
A = $20,000(1 + 0.05 x 5)
A = $20,000(1.25)
A = $25,000
So we get answer of $25,000, which is the total amount Brian will have in 5 years.
The cuboid below is made of nickel and has a mass of 534 g. Calculate its density, in g/cm³. If your answer is a decimal, give it to 1 d.p
The sοlutiοn οf the given prοblem οf cubοid cοmes οut tο be the cubοid has a density οf abοut 6.0 g/cm³.
Describe the cubοid.In geοmetry, a hypercube is a cοncrete οr muti shape. A hypercube is a cοnvex pοlygοns with 12 sides, 6 rectangular faces, and 8 edges. A cubοid is anοther term fοr the creature.

Here,
This equatiοn can be changed tο read density = mass/vοlume. Since we already knοw the mass (534 g), we can use the rearranged methοd tο determine the vοlume.
=> Vοlume = L, W, and H, and mass = 534 g.
=> density equals mass/vοlume
=> weight = 534/ (L x W x H)
The CRC Encyclοpedia οf Chemistry and Physics states that nickel has a density οf 8.908 g/cm³.
Thus, we can enter this number as a substitute in οur fοrmula tο οbtain:

X is a positive discrete uniform random variable. The mean and
the variance of X are equal to (µ,sigma2) = (5,4). Find
P(X>=6).
answers
(a) 3\7
(b) 1\2
(c) 2\7
As X is a discrete uniformly distributed random variable with a mean of 5, a variance of 4, and a range of values from 1, 2, 3, 5, 6, 7, 8, and 10, we know that X can have any one of these values with an equal probability of 1/10.
Calculating the likelihood that X will have a number equal to or greater to 6 is necessary to get [tex]P(X > =6)[/tex]. Due to the fact that X is a continuous uniformly distributed random variable.
We may calculate this probability simply counting all number of potential values for X that are greater or equal to to 6, dividing by the entirety of the potential values for X, and then adding the results together.
The probability of X is more than or equivalent to 6 is given by the fact there are a total of 5 variables of X that are at least equal to 6, namely: 6, 7, 8, 9, and 10.
[tex]P(X > =6) = 5/10 = 1/2[/tex]

Step-by-step explanation:
In one lottery, a player wins the jackpot by matching all five distinct numbers drawn in any order from the white balls (1 through ) and matching the number on the gold ball (1 through ). If one ticket is purchased, what is the probability of winning the jackpot?
Answer: The total number of possible outcomes in the lottery can be calculated by finding the number of ways to choose 5 distinct numbers out of 70, and then multiply that by the number of possible choices for the gold ball (1 out of 25). So:
Total number of outcomes = (70 choose 5) * 25 = 25,989,600
To win the jackpot, the player must match all 5 white ball numbers and the gold ball number. The number of ways to do this is simply 1, since there is only one winning combination.
Therefore, the probability of winning the jackpot with a single ticket is:
Probability of winning = (number of winning outcomes) / (total number of outcomes) = 1 / 25,989,600
So the probability of winning the jackpot with a single ticket is approximately 0.00000003846, or 1 in 25,989,600.

Q28) A neighborhood depanneur has determined that daily demand for milk cartons has an approximate normal distribution, with a mean of 65 cartons and a standard deviation of 7 cartons. On Saturdays, the demand for milk is known to exceed 71 cartons. On the coming Saturday, what is the probability that it will be at least 81 cartons?
The probability that there will be at least 81 cartoons on a coming Saturday is given as follows:
0.011 = 1.1%.
How to obtain probabilities using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.The mean and the standard deviation for this problem are given as follows:
[tex]\mu = 65, \sigma = 7[/tex]
The probability that there will be at least 81 cartoons is one subtracted by the p-value of Z when X = 81, hence:
Z = (81 - 65)/7
Z = 2.29
Z = 2.29 has a p-value of 0.989.

Answer:
The length of x is (10√3)/3.
Step-by-step explanation:
Using the trigonometric ratios of a 30-60-90 triangle, we know that the side opposite the 30-degree angle is half the length of the hypotenuse. Therefore, we have:
x/2 = (5/√3)
Multiplying both sides by 2, we get:
x = 10/√3, which can be simplified to:
x = (10√3)/3
So the length of x is (10√3)/3.

A rubber bouncy ball is dropped at a height of 120.00 inches onto a hard flat floor. After each bounce, the ball returns to a height that is 20\% less than the previous maximum height. What is the maximum height reached after the 7th bounce? Round your answer to the nearest hundredth.
Answer:
To solve the problem, we need to find the maximum height reached by the ball after the 7th bounce, given that each bounce has a rebound height of 20% less than the previous maximum height.
Let's start by finding the maximum height reached by the ball on the first bounce. The ball is dropped from a height of 120.00 inches, so the maximum height reached on the first bounce is:
120.00 inches
For each subsequent bounce, the maximum height reached is 20% less than the previous maximum height. We can express this mathematically as:
maximum height = 0.8 * previous maximum height
Using this formula, we can calculate the maximum height reached on the second bounce as:
maximum height on 2nd bounce = 0.8 * 120.00 inches = 96.00 inches
On the third bounce, the maximum height reached is 20% less than 96.00 inches:
maximum height on 3rd bounce = 0.8 * 96.00 inches = 76.80 inches
We can continue this pattern for each subsequent bounce. The maximum height reached on the fourth bounce is:
maximum height on 4th bounce = 0.8 * 76.80 inches = 61.44 inches
The maximum height reached on the fifth bounce is:
maximum height on 5th bounce = 0.8 * 61.44 inches = 49.15 inches
The maximum height reached on the sixth bounce is:
maximum height on 6th bounce = 0.8 * 49.15 inches = 39.32 inches
Finally, the maximum height reached on the seventh bounce is:
maximum height on 7th bounce = 0.8 * 39.32 inches = 31.46 inches
Therefore, the maximum height reached by the ball after the 7th bounce is approximately 31.46 inches. Rounded to the nearest hundredth, this is 31.45 inches.

After the last ice age began, the number of animal species in Australia changed rapidly. The relationship between the elapsed time, ttt, in years, since the ice age began, and the total number of animal species, S(t)S(t)S, left parenthesis, t, right parenthesis, is modeled by the following function: S(t)=4,200,000⋅(0. 72)t Complete the following sentence about the yearly percent change of the number of animal species
The yearly percent change in the number of animal species is approximately -67.68%. This means that the number of animal species is decreasing by about 67.68% each year after the last ice age began.
The yearly percent change of the number of animal species after the last ice age began can be calculated by taking the derivative of the function given, S(t)=4,200,000⋅(0.72)t. Using the power rule, the derivative of this function is S'(t)=2,976,000⋅(0.72)t-1. This tells us that the yearly percent change in the number of animal species is -72%. This means that every year, the total number of animal species decreases by 72%.
The yearly percent change of the number of animal species can be determined by finding the derivative of the function [tex]S(t) = 4,200,000(0.72)^t.[/tex]
The derivative of the function can be calculated as follows:[tex]S'(t) = 4,200,000 ln(0.72) (0.72)^t[/tex] The yearly percent change can be calculated by finding the percentage change in the total number of animal species for each year. This can be done by finding the percentage change in the value of the function for each year.
The percentage change in the value of the function can be calculated using the formula:% change = [(new value - old value) / old value] x 100Substituting the values of the function for different years in the above formula, we can find the percentage change for each year.
For example, if we want to find the percentage change in the number of animal species after 10 years, we can substitute t = 10 in the function and calculate the new value of S(t). Then, we can use the above formula to find the percentage change in the value of the function for 10 years.S(10) = 4,200,000(0.72)^10 ≈ 1,357,747% change = [(1,357,747 - 4,200,000) / 4,200,000] x 100 ≈ -67.68%

Answer:
≈ 18.8 cm
Step-by-step explanation:
Since the circle is inscribed in the square, the diameter of the circle is equal to the side length of the square.
The area of the square is given as 36 cm^2, so we can find the side length of the square as:
side length = √(area) = √(36 cm^2) = 6 cm
The diameter of the circle is therefore also 6 cm, and the radius of the circle is half the diameter, or 3 cm.
The circumference of a circle is given by the formula:
circumference = 2πr
where r is the radius of the circle.
Substituting in our values, we get:
circumference = 2π(3 cm) = 6π cm
Using a calculator to approximate π to one decimal place, we get:
circumference ≈ 18.8 cm
Therefore, the circumference of the circle inside the square is approximately 18.8 cm.

Microwave oven time = (26 x weight in kg) + 15
We can compare the two formulae by looking at their coefficients and constants. This suggests that the electric oven takes longer to cook the meat than the microwave oven, and that the difference in cooking times will increase with larger weights.
b) (66 x weight in kg) + (35 x time in an electric oven
2 x 60 = (66 x weight in kg) + 35
120 - 35 = 66 x weight in kg
85 = 66 x weight in kg
weight in kg = 85 / 66
weight in kg ≈ 1.29
So, a joint of meat that takes about 2 hours to cook in an electric oven weighs approximately 1.29 kg.
Microwave oven time = (26 x weight in kg) + 15
Microwave oven time = (26 x 1.29) + 15
Microwave oven time ≈ 48.34 minutes
Therefore, a 1.29 kg joint of meat would take about 48 minutes to cook in a microwave oven.
c) The answer to part a seems sensible, as the formula for the electric oven predicts longer cooking times than the formula for the microwave oven.

the lengths of human pregnancies (gestations) can be modeled by a bell-shaped distribution with mean 266 days and standard deviation 16 days. use the empirical rule to answer the questions below. what is the 84th percentile of the gestations?
The 84th percentile of gestations which can be ruled by standard deviation is 282 days.
The lengths of human pregnancies (gestations) can be modeled by a bell-shaped distribution with a mean of 266 days and a standard deviation of 16 days. Use the empirical rule to determine the 84th percentile of the gestations. The empirical rule, also known as the 68-95-99.7 percent rule, is a statistical guideline that states that within one standard deviation of the mean, 68 percent of the data is distributed.
Within two standard deviations of the mean, 95% of the data is distributed. Finally, 99.7 percent of the data is distributed within three standard deviations of the mean. As a result, it's necessary to locate the corresponding z-score for the given percentile to use the empirical rule.
Since we have the mean and standard deviation, we can use the following equation to compute the z-score using the formula: z = (X - µ)/σ where X is the value of interest, µ is the mean, and σ is the standard deviation. From the formula: z = (X - µ)/σX = µ + zσ Substituting the given values in the formula, we get: X = 266 + z(16)We need to find the 84th percentile.
This means that the remaining 16 percent of the data is distributed outside of the mean plus one standard deviation. As a result, the corresponding z-score can be found using a standard normal distribution table or calculator. The standard normal distribution table or calculator gives us the z-score of 1.00 for the 84th percentile. Using this, we can compute the value of X as follows: X = µ + zσX = 266 + (1.00)(16)X = 266 + 16X = 282
