Answer:

\(4*y^{1/7}\)

Step-by-step explanation:

Given

\(\frac{8y^{2} }{2\sqrt[4]{y} }\)

it can be written as we

=\(\frac{8y^{2} }{2*y^{1/4} }\)

= \(\frac{4y^{2} }{y^{1/4} }\)

= \(4y^{2-1/4}\)

= \(4y^{1/7}\)

Therefore the given solution is in the form of k * y^n

When a ticket is bought, there are 2 outcomes. It's either it comes with a popcorn or not. These outcomes are independent. This means that it is a binomial distribution. We would apply the binomial ditribution formula which is expressed as

P(x) = nCx * p^x * q^(n - x)

where

n is the number of trials

x is the number of successess

p is the probability of success

q is the probability of failure

A success in this case is the outcome of buying a ticket that has popcorn coupons. Thus,

p = 0.717

q = 1 - p = 1 - 0.717 = 0.283

n = 21

x = 14

We want to find P(x = 14)

Thus,

P(x = 14) = 21C14 * 0.717^14 * 0.283^(21 - 14)

P(x = 14) = 116280 0* 0.717^14 * 0.2837

P(x = 14) = 0.160

the probabilitythat exactly 14 of the tickets have popcorn coupons is 0.160)

Answer:

  10 meters

Step-by-step explanation:

You want the length of a 200 square meter tarp that has a width of 20 meters.

The area of a rectangle is given by ...

  A = LW

Filling in known values, we have ...

  200 m² = L · (20 m)

  L = (200 m²)/(20 m) = 10 m . . . . . . . divide by the coefficient of L

The tarp is 10 meters long.

The surface area of the right triangular prism is 312 square units.To find the surface area of a right triangular prism, we need to calculate the area of each face and then sum them up.

A right triangular prism has three rectangular faces and two triangular faces. Given the dimensions: Height (h) = 20 units, Legs of the base (a, b) = 3 units, 4 units, Hypotenuse of the base (c) = 5 units. Let's calculate the surface area: Area of the triangular face: The area of a triangle can be calculated using the formula: A = (1/2) * base * height. For the triangular face with legs of length 3 units and 4 units, the area is: A_triangular = (1/2) * 3 * 4 = 6 square units.

Since there are two triangular faces, the total area for the triangular faces is: Total area of triangular faces = 2 * A triangular = 2 * 6 = 12 square units. Area of the rectangular faces: The area of a rectangle is calculated as: A = length * width. For the rectangular faces, the length is the height of the prism (20 units), and the width is the base's hypotenuse (5 units). Since there are three rectangular faces, the total area for the rectangular faces is: Total area of rectangular faces = 3 * (20 * 5) = 300 square units.

Total surface area: The total surface area is the sum of the areas of all faces: Total surface area = Total area of triangular faces + Total area of rectangular faces. Total surface area = 12 + 300 = 312 square units.. Therefore, the surface area of the right triangular prism is 312 square units.

Answer:

4 cm.

Step-by-step explanation:

If 1cm = 10m, the increments of which you would draw the map would be directly proportional.

40m/10m = 4

4×1 = 4

Therefore, the answer is 4 cm.

Answer:

- There are more points above the line than below

- This is not a line of best fit

Step-by-step explanation:

       If we count the data points above and below the line, we can see there are about 4 below and 11 above. This means there are more points above the line than below. Since there are more points above the line than below, this is not a line of best fit.

Answer:

600

Step-by-step explanation:

Note that 600 is exactly half way between 400 and 800, and conclude therefore that 600 is the midpoint.

To solve the given problem, you must first identify the ratios of the pulleys. The ratio of a pulley is the relationship between its own diameter and that of another pulley.The formula for finding the ratio is.

D1/D2 = N1/N2Where:

D1 = diameter of pulley 1D2

= diameter of pulley 2N1

= speed of pulley 1N2

= speed of pulley 2A lineshaft runs at 360 rpm. An 18 inches pulley on the same shaft is belt connected to a 12 inches pulley on the counter shaft. Therefore, the ratio of the pulleys on the line shaft to those on the counter shaft are:18/12 = 3/2This means that for every three revolutions of the 18 inches pulley, the 12 inches pulley will rotate twice or vice versa.

The motion is transmitted to the machine via a 15 inches pulley on the counter shaft. From the given problem, the spindle speed on the machine should be 660 rpm. To find the diameter of the pulley on the machine, use the formula:D1/D2 = N1/N218/12

= N1/660660*18/12

= N1N1

= 990 rpmTherefore, the ratio of the pulley on the counter shaft to that on the machine is:15/D2

= 990/660D2

= 10.0 inchesThe required diameter of the pulley on the machine is 10 inches. Therefore, the correct response is 10.5 inches. Answer: 10.5 inches.

Because of the "x-5" in the absolute value, the pieces will separate at x=5, because that's where x-5 = 0.

(This knocks out answer #1, 3, and 4)

To confirm option #2 is correct:

If you pick a number greater than 5, the absolute value doesn't do anything, so

  if x > 5, a(x) = (x-5) + 1

If you pick a number less than 5, "x-5" is negative and the absolute value gives you the opposite of that value:

  if x < 5, a(x) = - (x-5) +1

The answer is the second option.

We enter the given numbers into the expression for wzyx in order to determine the value of wzyx at the location (5, -1, 1).

Let's first rebuild the wzyx equation using the supplied values:

The equation is: wzyx = reyz = r * (-1) * (1) * (5)

Given the coordinates (5, -1, 1), we may enter these values into the expression as follows:

Wzyx is equal to r * (-1) * (1) * (5), or -5r.

Wzyx thus has a value of -5r at the coordinates (5, -1, 1).

We are unable to precisely calculate the value of wzyx at the specified place without knowledge of the value of r. As a result, the question cannot be answered using the information given.

Step-by-step explanation:

A number can be written from the greatest to the and the lowest to the highest when given a series of number. This series of number can be in mixed fraction forms, improper fraction or decimal. When a number is said to be written from the greatest to the lowest, it is called descending order but from the lowest to the greatest it is called ascending order.

From the list of the series of the decimal numbers given, writing the numbers in order from the greatest to the least number will choose the form:

Step-by-step explanation:

Jackie pays $130 monthly for her group health insurance.

To find out how much Jackie pays for her group health insurance monthly, we need to calculate 40% of the annual cost. Given that the annual cost is $3,900 and her company pays 40% of that, we can calculate the amount Jackie pays.

First, we find the company's contribution by multiplying the annual cost by 40%: $3,900 × 0.40 = $1,560. This is the amount the company pays towards Jackie's health insurance.

To determine Jackie's monthly payment, we divide her annual payment by 12 (months in a year) since she pays monthly. So, Jackie's monthly payment is $1,560 ÷ 12 = $130.

Therefore, Jackie pays $130 per month for her group health insurance. This calculation takes into account the company's contribution of 40% of the annual cost, resulting in an affordable monthly payment for Jackie.
