If three hens lay 3 eggs any 3 days. The number of days that 3 Hens give in 9 eggs is: 9days.

<h3>Number of days that three hens lay 9 eggs</h3>

Given:

3 hens lay 3 eggs in 3 days

First step is to determine the number of egg one hen lay in 3 days

1 hen in 3 days lays 3/3

1 hen in 3 days lays=1 egg

Second step is to determine the number of egg 3 hens lay 1 day

1 hen in 1 day lays 1/3 egg

3 hens in 1day lay=(1×3)/3

3 hens in 1day lay=1 egg

Third step is to determine the number of eggs 3 hens lay in 9 days

3 hens in 9 days lay=(1×9)

3 hens in 9 days lay=9 eggs

Therefore assuming three hens lay 3 eggs any 3 days. The number of days that 3 Hens give in 9 eggs is: 9days.

A manufacturer of potato chips would like to know whether its bag filling machine works correctly at the 444 gram setting. It is
ankoles [38]

Answer:

The null hypothesis is H_0: \mu = 444

The alternative hypothesis is H_1: \mu < 444

The p-value of the test is 0.1148 > 0.05, which means that the sample does not give enough evidence to conclude that the machine is underfilling the bags.

Step-by-step explanation:

A manufacturer of potato chips would like to know whether its bag filling machine works correctly at the 444 gram setting.

At the null hypothesis, we test if the machine works correctly, that is, the mean is of 444. So

H_0: \mu = 444

At the alternative hypothesis, we test if they are underfilling, that is, if the mean is of less than 444. So

H_1: \mu < 444

The test statistic is:

t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}

In which X is the sample mean, \mu is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.

444 is tested at the null hypothesis:

This means that \mu = 444

A 41 bag sample had a mean of 440 grams with a variance of 441.

This means that n = 41, X = 440, s = \sqrt{441} = 21

Value of the test statistic:

t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}

t = \frac{440 - 444}{\frac{21}{\sqrt{41}}}

t = -1.22

P-value of the test:

Right-tailed test(test if the mean is less than a value), with 41 - 1 = 40 df and t = -1.22.

Using a t-distribution calculator, this p-value is of 0.1148

The p-value of the test is 0.1148 > 0.05, which means that the sample does not give enough evidence to conclude that the machine is underfilling the bags.

The rectangular prism is increased by a factor of three. By what factor does the volume increase?
KiRa [710]

Answer:

27

Step-by-step explanation:

Suppose that the dimensions of the rectangular prism are L, W and H.

Then the volume is V = L*W*H.

If you mean to increase EACH dimension by a factor of 3, then we' have

V = (3L)*(3W)*(3H), or V = 27 L*W*H.

The volume of the modified prism would be 27 times larger than that of the original prism.

What is the answer????
Liula [17]

Answer:

(5, 6)

Step-by-step explanation:

<u>Step 1:  Solve for x in the first equation </u>

x - y + y = -1 + y

x = y - 1

<u>Step 2:  Plug in x into the second equation </u>

(y - 1) - 3y = -13

y - 1 - 3y + 1 = -13 + 1

-2y / -2 = -12 / -2

y = 6

<u>Step 3:  Plug in y into the first equation </u>

<u />x - (6) + 6 = -1 + 6

x = 5

Answer:  (5, 6)
