A bag of peanuts could be divided among 8 children, 9 children, or 10 children with each getting the same number, and with 2 peanuts left over in each case. The smallest number of peanuts that could be in the bag is 26.

This is because 8 children could each get 3 peanuts and there would be 2 peanuts left over, 9 children could each get 2 peanuts and there would be 2 peanuts left over, and 10 children could each get 2 peanuts and there would be 2 peanuts left over.

Small number means a number that is insufficiently large to be statistically significant, as determined by the department. Counting numerals are included in whole numbers as well. Whole numbers begin at zero. As a result, the least whole number is 0. Even though zero has no value, it is employed as a placeholder.

The volume increase when the radius changes from 7 to 7.1 ft is 62.45 ft³ i.e. 4.34%. of the previous volume.

We know that the volume of the sphere is 4/3πr³.

So, here the radius of the sphere is 7 ft,

Therefore the volume of the sphere will be = 4/3π(7)³.

so, V1 = 4/3*3.14*(7)³.

V1 = 1436.76  ft³.

When the radius of the sphere will increase tp 7.1 feet then the volume will also increase which will be :

V2 = 4/3*3.14*(7.1)³.

V2 = 1499.21 ft³.

Now the increase in volume is V2- V1 .

which is , 1499.21 ft³ -  1436.76  ft³

i.e. 62.45 ft³ is the increase of the volume of the sphere.

This increased volume is the 4.34% of the previous volume of the sphere.

The temperature of the soda after 20 minutes is approximately -18 degrees Celsius. To find the initial temperature of the soda, we can evaluate the function T(x) at x = 0.

Substitute x = 0 into the function T(x):

T(0) = -19 + 39e^(-0.45*0).

Simplify the expression:

T(0) = -19 + 39e^0.

Since e^0 equals 1, the expression simplifies to:

T(0) = -19 + 39.

Calculate the sum:

T(0) = 20.

Therefore, the initial temperature of the soda is 20 degrees Celsius.

To find the temperature of the soda after 20 minutes, we substitute x = 20 into the function T(x):

Substitute x = 20 into the function T(x):

T(20) = -19 + 39e^(-0.45*20).

Simplify the expression:

T(20) = -19 + 39e^(-9).

Use a calculator to evaluate the exponential term:

T(20) = -19 + 39 * 0.00012341.

Calculate the sum:

T(20) ≈ -19 + 0.00480599.

Round the answer to the nearest degree:

T(20) ≈ -19 + 1.

Therefore, the temperature of the soda after 20 minutes is approximately -18 degrees Celsius.

Answer:

A= 648 :)

Step-by-step explanation:

The rate of change of output with respect to skilled workers when 18 skilled workers and 31 unskilled workers are employed is 427.94.

Given, the function is z = f(x, y)

= 14500x + 4000y + 15x²y - 11x³

Where, z = the weekly # of pounds of acetate fiber

X = the # of skilled workers at the planty = the # of unskilled workers at the plant

(a) We are given the values of skilled workers and unskilled workers, we need to calculate the number of pounds of fiber that can be produced.

Put x = 18

and y = 31 in the given function

z = f(x, y)

= 14500x + 4000y + 15x²y - 11x³z

= 14500 (18) + 4000 (31) + 15 (18)² (31) - 11 (18)³

= 261180 lbs

Hence, the weekly number of pounds of fiber that can be produced with 18 skilled workers and 31 unskilled workers is 261180 lbs.

(b) We need to find an expression (fx) for the rate of change of output with respect to the number of skilled workers.

Differentiate the given function with respect to x.

z = f(x, y)

= 14500x + 4000y + 15x²y - 11x³∂z/∂x

= 14500 + 30xy - 33x²

= 14500 + 30y (x - 11x²/30y)fx

= ∂z/∂x = 14500 + 30y (x - 11x²/30y)

Hence, the expression (fx) for the rate of change of output with respect to the number of skilled workers is fx = 14500 + 30y (x - 11x²/30y).

(c) We need to find an expression (fy) for the rate of change of output with respect to the number of unskilled workers.

Differentiate the given function with respect to y.z

= f(x, y)

= 14500x + 4000y + 15x²y - 11x³∂z/∂y

= 4000 + 15x²

= 15 (x² + 267)fy

= ∂z/∂y

= 15 (x² + 267)

Hence, the expression (fy) for the rate of change of output with respect to the number of unskilled workers is fy = 15 (x² + 267).

(d) We need to find the rate of change of output with respect to skilled workers when 18 skilled workers and 31 unskilled workers are employed.

Put x = 18 and

y = 31 in the expression of fx.

fx = 14500 + 30y (x - 11x²/30y)

= 14500 + 30 (31) (18) - 11 (18)² / 31

= 14500 + 16740 - 12762/31

= 427.94

Hence, the rate of change of output with respect to skilled workers when 18 skilled workers and 31 unskilled workers are employed is 427.94.

The red line represents the critical value, and the shaded region on the right-hand side of the red line represents the rejection region. If the calculated test statistic is greater than the critical value of z, which is 1.88 in this case, we will reject the null hypothesis.

The critical value(s) and rejection region(s) for the type of z-test with a level of significance a = 0.03 and a right-tailed test are as follows :Step 1: Determine the critical value of  zThe critical value is calculated by using the normal distribution table and the level of significance. A right-tailed test will have a critical value of zα. For a level of significance of 0.03, we will look for the z-value that corresponds to 0.03 in the normal distribution table.Critical value for a = 0.03 is z = 1.88 (approx).Step 2: Determine the Rejection Region The rejection region for a right-tailed test is defined as any z-value that is greater than the critical value. That is, if the test statistic is greater than 1.88, we reject the null hypothesis at the 0.03 level of significance, and if it is less than or equal to 1.88, we fail to reject the null hypothesis.Therefore, the rejection region for a right-tailed test with a level of significance of 0.03 is as follows:Rejection Region: Z > 1.88  OR  Z ≤ -1.88Graph: The graph for the given values will be as follows:The red line represents the critical value, and the shaded region on the right-hand side of the red line represents the rejection region.

The image of the straight lines is missing so i have attached it.

Answer:

x = 20°

y = 120°

Step-by-step explanation:

From the image attached, we can say that;

3x + (7x - 20) = 180

This is because sum of angles on a straight line is 180°

Thus;

3x + 7x - 20 = 180

10x = 180 + 20

10x = 200

x = 200/10

x = 20°

Also,3x + y = 180

Because sum of angles on a straight line is 180°. Thus;

3(20) + y = 180

60 + y = 180

y = 180 - 60

y = 120°

The probability that 2 of 5 customers are vegetarian is 0.0981 or 9.81%.

The given case represents a binomial distribution. Binomial distribution refers to a discrete probability distribution that is characterized by two possible results (success or failure) and each trial has the same probability of attaining one particular value. It determines the probability of attaining a specified number of successful outcomes (x) in a specified number of trials (n).

P(x)\ =\frac{n!}{x!(n-x)!}\ast p^x\ast{(1-p)}^{n-x}

Where n is the total number of outcomes, x is the desired outcome, and p is the probability of success. In the given case, n = 5; x = 2; and p = 0.12.

P(x)\ =\frac{n!}{x!(n-x)!}\ast p^x\ast{(1-p)}^{n-x}

The volume of each ball is (32/3)π cubic inches, and the volume of water just enough to cover the four balls is also (32/3)π cubic inches.

First, let's calculate the volume of each ball. The diameter of each ball is given as 4 inches, so the radius (half the diameter) of each ball is 2 inches. The formula to calculate the volume of a sphere is V = (4/3)πr^3, where V represents volume and r represents the radius.

For each ball, the volume is:

V = (4/3)π(2³)

V = (4/3)π(8)

V = (32/3)π cubic inches

Since there are three balls at the bottom of the jar, the combined volume of these three balls would be:

3 * (32/3)π = 32π cubic inches

Now, let's consider the fourth ball. Since it is dropped on top of the three balls, it will displace some water, and the volume of the water needed to cover the four balls will be equal to the volume of the fourth ball.

To find the volume of the fourth ball, we use the same formula:

V = (4/3)πr³

Since the diameter of the fourth ball is also 4 inches, its radius is 2 inches. Substituting this value into the formula, we get:

V = (4/3)π(2³)

V = (4/3)π(8)

V = (32/3)π cubic inches

Therefore, the volume of water required to cover the four balls is also (32/3)π cubic inches.
