Q2: 2 kids get 2 pieces of taffy and 1 piece of licorice and the other three get 2 pieces of licorice and 1 piece of taffy.

Step-by-step explanation:

question 2 is quite obvious but no one can get the same amount of everything so the answer that i gave makes the most sense.

The equation of the line that is perpendicular to the equation is y = -1/5x

The given line has a slope of 5, which means that any line perpendicular to it will have a slope that is the negative reciprocal of 5. The negative reciprocal of 5 is -1/5.

Let m be the slope of the line perpendicular to y = 5x - 2. Then, the equation of this line can be written in point-slope form as:

y - y1 = m(x - x1)

where (x1, y1) is the point where the line passes through, which is the origin in this case. So, we have:

y - 0 = (-1/5)(x - 0)

Simplifying this equation, we get:

y = (-1/5)x

Therefore, the line perpendicular to y = 5x - 2 and passing through the origin has a slope of -1/5 and a y-intercept of 0. Its equation is y = (-1/5)x.

Answer: 2 hours

Step-by-step explanation: (10 min) / (25 square feet)   =  (X minutes) / (300 square feet)

Cross-multiply to solve, as we always do with proportions:

10 * 300  = 25 * x

3000       = 25X

Step-by-step explanation:

The square root of 22 is an irrational number, which means it cannot be expressed exactly as a finite decimal or a fraction. However, we can approximate it by finding the whole number that is closest to it.

To do this, we can use a calculator or estimation. For example, we can guess that the square root of 22 is between 4 and 5, since 4 squared is 16 and 5 squared is 25. Then we can try averaging these two numbers:

(4 + 5) / 2 = 4.5

This means that 4.5 is an approximate value of the square root of 22. The nearest whole number to 4.5 is 5, so we can say that the whole number nearest to the square root of 22 is 5.

From the given information provided, the probability of P(X ≤ 6), P(X˃ 4) and P(|X- 5| ˃ 1) is 0.6915, 0.6915 and 0.3829 respectively.

(i) To find P(X ≤ 6), we need to standardize the value of 6 using the formula:

Z = (X - μ) / σ

where μ = 5 and σ = 2 (since the standard deviation is the square root of the variance, which is 4).

So, we have:

Z = (6 - 5) / 2

Z = 0.5

We can then look up the probability of Z ≤ 0.5 in a standard normal distribution table, or use a calculator to find:

P(X ≤ 6) = P(Z ≤ 0.5) = 0.6915

(ii) To find P(X > 4), we again need to standardize the value of 4:

Z = (4 - 5) / 2

Z = -0.5

Then, we can use the fact that the total area under a normal distribution curve is 1 to find the probability of X being greater than 4:

P(X > 4) = 1 - P(X ≤ 4) = 1 - P(Z ≤ -0.5)

Using a standard normal distribution table:

P(X > 4) = 0.6915

(iii) To find P(|X - 5| > 1), we first need to transform this inequality into a standard normal distribution by standardizing both sides:

|X - 5| > 1

implies:

X - 5 > 1 or

X - 5 < -1

which gives:

X > 6 or X < 4

We can then standardize each inequality separately. For X > 6, we have:

Z = (6 - 5) / 2

Z = 0.5

and for X < 4, we have:

Z = (4 - 5) / 2 = -0.5

Then, using the fact that the total area under a normal distribution curve is 1, we can find the probability of both events occurring:

P(|X - 5| > 1) = P(X > 6 or X < 4) = P(Z > 0.5 or Z < -0.5)

Since the standard normal distribution is symmetric around 0:

P(Z > 0.5 or Z < -0.5) = 2 × P(Z < -0.5)

Using a standard normal distribution table:

P(|X - 5| > 1) = 0.3829

Answer:

To ensure that you have grabbed 250 balls of one color, you need to use the Pigeonhole Principle. The worst-case scenario is that you grab 249 balls of each color, totaling 996 balls. Therefore, the smallest amount of balls you need to grab is 997, which guarantees that you have grabbed 250 balls of one color.

To explain further, let's consider the worst-case scenario where you grab 249 red balls, 249 green balls, 249 blue balls, and 249 yellow balls. This totals to 996 balls. However, if you grab just one more ball, you will have a total of 997 balls, and since there are only four colors, at least one color will have 250 balls or more. Therefore, by grabbing 997 balls, you can be sure that you have grabbed at least 250 balls of one color.

Answer:

997

Step-by-step explanation:

I multiplied 249 by 4 first. This is because I wanted to find how many balls the person could grab in total without having 250 of the same color.

249*4= 996

However, the question wants to guarantee that one color has 250.

So I did 996+1=997. (which means there could be: 249 red, 249 yellow, 249 green, and 250 blue)

This means that every other color could be at 249, but one would guarantee to be at 250 with 997 pulls

The multiplicative rate of change of a function is calculated by taking the ratio of the change in the output to the change in the input, which in this case would be 2.

The multiplicative rate of change of a function is the rate at which the output of the function changes in relation to the input. It is calculated by taking the ratio of the change in the output to the change in the input. The formula for this is:

Multiplicative Rate of Change = (Change in Output)/(Change in Input)

For example, if a function f(x) has an input of 3 and an output of 9, then the multiplicative rate of change of the function would be 2. This can be calculated by taking the difference between the output and the input, which is 9 - 3 = 6, and dividing it by the difference between the input and the output, which is 3 - 0 = 3. Thus, the multiplicative rate of change of the function is 6/3 = 2.

In geometry, a coordinate system is a method that uses one or more numbers or coordinates to determine the precise location of points or other physical objects on a basis, such as Reference frame. Pairs of figures called coordinates are employed in order to locate a point or item on a double plane. The x and y parameters of a location on a 2D plane are two integers that describe its position. a set of digits which represent precise positions. In most cases, the figure has two numbers. The first number represents the front-to-back distance, while the second column represents the top-to-bottom distance. As in (12.5), there are 12 divisions below and 5 units above.

To determine the image of point S after dilation with the origin as the centre and a scale factor of 12, multiply S's coordinates by the scale factor of 12.

As a result, the coordinates of point S after dilation are as follows:

About 16 people among the 1,000 insured people can file a claim for a surgical procedure.

Profit is the financial gain earned by a business or an individual after deducting all the expenses and costs associated with generating that revenue. It represents the difference between the total revenue earned and the total expenses incurred.

The total amount collected in premiums over 3 years for Bracken is:

$100 x 1,000 x 3 = $300,000

Assuming x people among the 1,000 insured people file a claim for a surgical procedure, the total amount paid out in claims by Bracken would be:

$25,000 x x = $25,000x

The total deductible paid by the claimants would be:

$3,500 x x = $3,500x

So, the total amount paid out by Bracken would be:

$25,000x + $3,500x = $28,500x

For Bracken to break even, the total amount collected in premiums should be equal to the total amount paid out in claims plus the deductible for 3 years.

$300,000 = $28,500x + $3,500(1,000 - x)

Simplifying and solving for x, we get:

x = 16

The formula for the volume of a cylinder is V = πr^2h, where r is the radius and h is the height. We are given the diameter of the cylinder, which is 4 inches, so the radius is half of that, or 2 inches. We are also given the volume of the cylinder, which is V = cubic inches.

Substituting these values into the formula, we get:

cubic inches = π(2 inches)^2h

Simplifying, we have:

cubic inches = 4πh

To solve for h, we can divide both sides by 4π:

h = cubic inches / 4π

Using a calculator to evaluate this expression, we get:

h = 5.027 inches (rounded to three decimal places)

Therefore, the height of the poster storage tube is approximately 5.027 inches.

The value of  tan(A - B)  will be 15/8.

As mentioned,  cscA= -17/15 and A is in Quadrant III and sinB=12/13 where B is in Quadrant I To find tan(A - B), we need to have the values of sin (A - B) and cos (A - B).We know that, sin(A - B) = sinAcosB - cosAsinB and cos(A - B) = cosAcosB + sinAsinB.Since we have the values of sinA, cosA, and sinB, let's find the values of cosA and cosB.First, let's find cosA. We know that cscA = 1/sinA. Therefore, sinA = -15/17.Since A is in Quadrant III, sinA < 0, cosA < 0, and tanA > 0.

By using the Pythagorean identity sin^2A + cos^2A = 1, we get cosA = -8/17.Next, let's find cosB. We know that sin^2B + cos^2B = 1.

Therefore, cosB = sqrt(1 - sin^2B) = 5/13.

Since B is in Quadrant I, sinB > 0, cosB > 0, and tanB > 0.

Now, we have sinA, cosA, sinB, and cosB.

Using the values of sinA, cosA, sinB, and cosB, let's find sin(A - B) and cos(A - B).

sin(A - B) = sinAcosB - cosAsinB= (-15/17)(12/13) - (-8/17)(5/13)= -180/221

cos(A - B) = cosAcosB + sinAsinB= (-8/17)(12/13) + (-15/17)(5/13)= -96/221

Finally, tan(A - B) = sin(A - B) / cos(A - B)= (-180/221) / (-96/221)= 15/8. Therefore, tan(A - B) = 15/8.

A triangular bandana has an area of 86 square inches. The height of the triangle is 5 3/8 inches. An equation to find the length of the base of the triangle is 86 = 1/2 * b * 43/8

The length of the triangle's base is 32 inches.

We know that the formula for calculating the area of a triangle is:

1/2 * base * height = area

We also know that the triangle's height is 5 3/8 inches, which may be expressed as a mixed number:

Height = 5 + 3/8 inch = 43/8 inch

Let b be the base of the triangle.

Substituting these numbers into the area formula yields:

86 = 1/2 * b * 43/8

To find b, multiply both sides of the equation by 2/43:

86 * 2/43 = 2/43 * 1/2 * b * 43/8

4 = b/8
