Answer:
220 adults and 250 children
Step-by-step explanation:
we require to set up 2 equations and solve simultaneously.
let a be the number of adults and c the number of children , then
a + c = 470 → (1) based on number of people
3a + c = 910 → (2) based on ticket sales
subtract (1) from (2) term by term to eliminate c
(3a - a) + (c - c) = 910 - 470
2a + 0 = 440
2a = 440 ( divide both sides by 2 )
a = 220
substitute a = 220 into (1) and solve for c
220 + c = 470 ( subtract 220 from both sides )
c = 250
that is 220 adults and 250 children attended

5 years ago the ratio of mark's age was 3:4 mark is 12 yr younger than francis how old is francis now.
5 years ago the ratio of Mark's age was 3:4 mark is 12 yr younger than Francis, now Francis is currently 53 years old
Let us suppose that age of him 5 years ago was 3x and Francis's age 5 years ago was 4x. According to the given information, Mark is 12 years younger than Francis.
So, we can set up the equation: 3x + 12 = 4x.
Simplifying the equation, we have: 12 = x.
This means that 5 years ago,
Mark age = 3 * 12 = 36 years old,
Francis age = 4 * 12 = 48 years old.
Now, to find out how old Francis is now, we add 5 years to both Mark and Francis. Thus, Francis's current age is 48 + 5 = 53 years.
Therefore, Francis is currently 53 years old.

your credit card has a balance of $3600 and an annual interest rate of 16%. you decide to pay off the balance over three years. if there are no further purchases charged to the card, you must pay $126.59 each month, and you will pay a total interest of $957.24. assume you decide to pay off the balance over one year rather than three. how much more must you pay each month and how much less will you pay in total interest?
You will need to pay $261.76 more each month if you want to pay off the balance in one year instead of three. However, you will save a total of $953.24 - $576 = $377.24 in interest by paying off the balance in one year instead of three.
If you decide to pay off the balance over one year instead of three, the payment amount will be higher, but the total interest paid will be lower due to the shorter repayment period.
First, let's calculate the total interest paid over three years. The total payment made over three years will be the monthly payment of $126.59 times 36 months, which is $4,553.24. The total interest paid is the difference between the total payment made and the initial balance of $3600, which is $953.24.
Now, let's consider paying off the balance over one year. The total payment made over one year will be the monthly payment of $126.59 times 12 months, which is $1,519.08. To calculate the interest paid, we can use the formula:
Total interest paid = Balance × Annual interest rate × Time
where the time is expressed in years. Plugging in the values, we get:
Total interest paid = $3600 × 0.16 × 1 = $576
Therefore, if you decide to pay off the balance over one year instead of three, you will pay an additional amount each month equal to the difference between the monthly payment for one year and the monthly payment for three years, which is:
Additional monthly payment = ($4,553.24/12) - ($1,519.08/12) = $261.76
This means that you will need to pay $261.76 more each month if you want to pay off the balance in one year instead of three. However, you will save a total of $953.24 - $576 = $377.24 in interest by paying off the balance in one year instead of three.

A sensor is used to monitor the performance of a nuclear reactor. The sensor accurately reflects the state of the reactor with a probability of .97. But with a probability of .02, it gives a false alarm (by reporting excessive radiation even though the reactor is performing normally), and with a probability of .01, it misses excessive radiation (by failing to report excessive radiation even though the reactor is performing abnormally).
What is the probability that a sensor will give an incorrect report, that is, either a false alarm or a miss?
To reduce costly shutdowns caused by false alarms, management introduces a second completely independent sensor, and the reactor is shut down only when both sensors report excessive radiation. (According to this perspective, solitary reports of excessive radiation should be viewed as false alarms and ignored, since both sensors provide accurate information much of the time.) What is the new probability that the reactor will be shut down because of simultaneous false alarms by both the first and second sensors?
Being more concerned about failures to detect excessive radiation, someone who lives near the nuclear reactor proposes an entirely different strategy: Shut down the reactor whenever either sensor reports excessive radiation. (According to this point of view, even a solitary report of excessive radiation should trigger a shutdown, since a failure to detect excessive radiation is potentially catastrophic.) If this policy were adopted, what is the new probability that excessive radiation will be missed simultaneously by both the first and second sensors?
1. The probability that the sensor will give an incorrect report is 0.03 or 3%.
2. The probability that the reactor will be shut down because of simultaneous false alarms by both sensors is 0.0004 or 0.04%.
3. The probability that excessive radiation will be missed simultaneously by both sensors is 0.0001 or 0.01%.
1. Probability of the sensor giving an incorrect report (false alarm or miss):The probability of a false alarm is 0.02.
The probability of a miss is 0.01.
P(false alarm or miss)
= P(false alarm) + P(miss)
= 0.02 + 0.01 = 0.03
Therefore, the probability that the sensor will give an incorrect report is 0.03 or 3%.
2. Probability of simultaneous false alarms by both sensors:
P(false alarm by both sensors)
= P(false alarm by sensor 1) * P(false alarm by sensor 2)
= 0.02 * 0.02
= 0.0004
Therefore, the probability that the reactor will be shut down because of simultaneous false alarms by both sensors is 0.0004 or 0.04%.
3. Probability of missing excessive radiation by both sensors:
P(miss by both sensors)
= P(miss by sensor 1) * P(miss by sensor 2)
= 0.01 * 0.01
= 0.0001
Therefore, the probability that excessive radiation will be missed simultaneously by both sensors is 0.0001 or 0.01%.

15. The volumes of two similar solids are 857.5 mm^3 and 540 mm^3. The surface area of the smaller solid is 108 mm^2. What is the surface area of the larger solid?
The required surface area of the larger solid is approximately 147 mm². Option A is correct.
We know that,
The surface area of any form is the area of the shape that is fronted.
The surface area of a 3D object is the amount of area covering the outside.
Let's say the surface area of the bigger solid S.
Since the two solids are similar, their volumes have a ratio of (side length)³.
Let's say the ratio of the side lengths of the larger to the smaller solid as k. Then,
⇒ k³ (540 mm³) = 857.5 mm³
Simplifying the above equation, we get:
⇒ k = 7/6
So, the larger solid is about 7/6=1.183 times bigger than the smaller solid in terms of side length.
Since the surface area has a ratio of (side length)²,
we can find the surface area of the larger solid by:
⇒ (1.83²)(108 mm³)
≈ 174 mm³
Therefore, the surface area of the larger solid is approximately 147 mm².

So you have 24 marbles in total (half blue and half red) with each of the numbers 1-12 appearing twice (once in each color). You draw one marble at random, replace it to the bag, mix up the marbles, and draw a second marble. Determine each of the following probabilities. P ( first marble is blue and second marble is red ) =
The probability that the first marble drawn is blue and the second marble drawn is red is 1/4 or 0.25, which can also be expressed as 25%.
To determine the probability of drawing a blue marble on the first draw and a red marble on the second draw, we need to consider the total number of marbles and the number of blue and red marbles in the bag
In this case, we have a bag with 12 blue marbles and 12 red marbles, making a total of 24 marbles.
When drawing the first marble, there is a 12/24 probability of selecting a blue marble since there are 12 blue marbles out of the total 24 marbles in the bag.
After replacing the first marble back into the bag and mixing up the marbles, the probability of drawing a red marble on the second draw is also 12/24, as there are still 12 red marbles remaining out of the total 24 marbles.
To find the overall probability, we multiply the probabilities of each event since they are independent events:
P(first marble is blue and second marble is red) = P(first marble is blue)[tex]\times[/tex]P(second marble is red)

The graph showing a circle with a center (-3, 2) and a radius of 3 does not represent all possible centers for a circle passing through (3, -1) with a radius of 4.
The graph represents a specific circle with its own center and radius.
To find all possible centers for a circle passing through a given point, we need to consider the locus of points equidistant from the given point.
In this case, the locus of points equidistant from (3, -1) with a radius of 4 forms another circle with a different center and radius.
The graph showing a circle with a center (-3, 2) and a radius of 3 does not represent all possible centers for a circle passing through (3, -1) with a radius of 4.

Given statement solution is:- The coordinates of point B is (3, 50°).
In the given scenario, we have point A with polar coordinates (2, 50°) and the pole O. We need to find point B such that OA is parallel to OB and OB has a length of 3 units.
Since OA and OB are parallel, they have the same angle with the positive x-axis. Therefore, the angle between OB and the positive x-axis would also be 50°.
To find the coordinates of point B, we can use the polar coordinates system, where the distance from the pole is denoted by r and the angle with the positive x-axis is denoted by θ.
Since OB has a length of 3 units, the distance from the pole (r) would be 3. The angle between OB and the positive x-axis is also 50°. Therefore, the coordinates of point B would be (3, 50°).
So, one possible answer for the coordinates of point B is (3, 50°).

The equation of the parabola that models the cross section of the reflector is: y = (1/32)x².
To model a cross section of the reflector as a parabola that opens upward and has its vertex at the origin,
We can use the standard equation for a parabola in vertex form:
y = a(x - h)² + k
In this equation, (h, k) represents the coordinates of the vertex.
Since we want the vertex to be at the origin (0, 0), the equation becomes:
y = ax²
To determine the value of 'a,' we can use the given information that the bulb is located 8 inches from the vertex.
Since the bulb is located at the focus, we know that the distance from the vertex to the focus (f) is also 8 inches.
In a parabola, the distance from the vertex to the focus is given by the formula f = 1/(4a).
Plugging in the value of f (8) into the formula, we can solve for 'a':
8 = 1/(4a)
32a = 1
a = 1/32
Therefore, the equation of the parabola that models the cross section of the reflector is: y = (1/32)x²

5. 49% of adults say cashews are their favorite kind of nut. You randomly select 19 adults and ask

their favorite nut is exactly four. (Round to the nearest thousandth as needed.)
6. According to the website nationalbikeregistry.com, at UCLA only 3% of stolen bikes are returned
to owners. If there are 335 bikes stolen at UCLA what is the probability that 12 or more stolen
bikes will be returned? (Round to the nearest thousandth as needed.)
The probability that exactly four out of 19 adults say cashews are their favorite nut is approximately 0.251.
The probability that 12 or more stolen bikes will be returned is approximately 0.026 (rounded to the nearest thousandth).
To solve both of these probability problems, we can use the binomial probability formula:
P(X = k) = (n C k) × p^k × (1 - p)^(n - k)
where:
P(X = k) is the probability of getting exactly k successes
n is the total number of trials
k is the number of desired successes
p is the probability of success in a single trial
(1 - p) is the probability of failure in a single trial
(n C k) represents the binomial coefficient, calculated as n! / (k! x (n - k)!)
Let's solve each problem separately:
The probability that exactly four out of 19 adults say cashews are their favorite nut can be calculated as:
P(X = 4) = (19 C 4) ⁴(0.49⁴) (0.51¹⁵)
Using the binomial probability formula, we can calculate:
P(X = 4) ≈ 0.251
Therefore, the probability that exactly four out of 19 adults say cashews are their favorite nut is approximately 0.251.
To find the probability that 12 or more stolen bikes will be returned out of 335 stolen bikes, we can use the binomial probability formula. Let's denote the probability of a stolen bike being returned as p = 0.03, the number of trials as n = 335, and the number of desired successes as k = 12 or more.
Using the complement rule, we can calculate the probability of not getting 11 or fewer successes:
P(X ≥ 12) = 1 - [P(X = 0) + P(X = 1) + ... + P(X = 11)]
To perform the calculation, summing up individual probabilities can be time-consuming. However, using statistical software or a binomial probability calculator can provide a convenient solution.
Using such a calculator, we find that the probability of 11 or fewer stolen bikes being returned is approximately 0.974. Therefore, the probability of 12 or more stolen bikes being returned is:
P(X ≥ 12) = 1 - 0.974 ≈ 0.026
Thus, the probability that 12 or more stolen bikes will be returned is approximately 0.026 (rounded to the nearest thousandth).

sorry i am unsure about rest, they do not have a value. good luck :)
Complete the work to solve for y: 2 5 ( 1 2 y + 5 ) − 4 5 = 1 2 y − 1 + 1 10 y 1.Distributive property: 1 5 y + 2 − 4 5 = 1 2 y − 1 + 1 10 y 2.Combine like terms: 1 5 y + 6 5 = 3 5 y − 1 3.Subtraction property of equality: 6 5 = 2 5 y − 1 Addition property of equality: 11 5 = 2 5 y 4.Division property of equality: What is the value for y?
The value of y is 4.4.
Let's go through the steps to solve for y:
Distributive property:
[tex]1/5y + 2 - 4/5 = 1/2y - 1 + 1/10y[/tex]
Combine like terms:
[tex]1/5y + 2 - 4/5 = 1/2y - 1 + 1/10y[/tex]
Simplify the equation by getting rid of fractions. To do this, we can multiply every term by the least common denominator (LCD) of 10:
[tex]10 * (1/5y + 6/5) = 10 * (3/5y - 1 + 1/10y)[/tex]
Simplifying further:
[tex]2y + 12 = 6y - 10 + y[/tex]
Now, let's combine like terms again:
[tex]2y + 12 = 7y - 10[/tex]
Next, let's isolate the variable y. Subtract 2y from both sides and add 10 to both sides:
[tex]12 + 10 = 7y - 2y[/tex]
Simplifying:
22 = 5y
Finally, divide both sides by 5 to solve for y:
y = 22/5
Note: It's important to check our solution by substituting y = 4.4 back into the original equation to ensure it satisfies the equation.

I dont get this question equation
y=0.5 (6) - 4
I know that 0.5 is equivalent to 1/2 but I just don’t get this question
Answer
[tex]\pink\sf{y=-1}[/tex]
Step-by-step explanation
I'm assuming that this exercise is asking us to simplify the equation [tex]\sf{y=0.5(6)-4}[/tex].
We know that 0.5 (6) means 0.5 multiplied by 6. That is the same as 6 divided by 2, which is 3:
[tex]\sf{y=3-4}[/tex]
And now we just simplify the last part:
[tex]\sf{y=-1}[/tex]
∴ answer: y = -1
