Answer:

\large\fbox{\purple{\underline{Circumference of circle is 163.28 yards}}}

Step-by-step explanation:

In the question we have given

Diameter of circle is 52 yards

And Value of π = 3.14

We know that

Circumference of circle = π × diamter

putting the values

Circumference = 3.14 × 52 yards

by mutiplying we get,

Circumference of circle = 163.28 yards

Therefore, Circumference of circle is 163.28 yards

Answer:

\boxed {\boxed {\sf 163.28 \ yards}}

Step-by-step explanation:

The circumference of a circle is the distance around the circle, or the perimeter. It is the product of pi and the diameter.

c= \pi \times d

The diameter is the distance from one side to the other through the center. If we look at the circle given, we see the diameter must be 52 yards.

  • d= 52 yd

Also, remember we are using 3.14 for pi.

  • \pi= 3.14

Substitute these values into the formula.

c= 3.14 * 52 \ yd

Multiply.

c=163.28 \ yd

The circumference of the circle is <u>163.28 yards.</u>

Jojo likes to paint. She estimates the number of paintings she completes using the function P of w equals two thirds times w min
pantera1 [17]

Answer:

P = \frac{2}{3} [J(y)] - 2

Step-by-step explanation:

If Jojo completes P number of paintings working w weeks then the relation between P and w is given by P = \frac{2}{3} w - 2. ........ (1)

Again, the function J(y) represents how many weeks per year she spends painting.

So, w = J(y). ...... (2)

Therefore, the composite function which represent how many paintings Jojo completes in a year, is given by  

P = \frac{2}{3} [J(y)] - 2  (Answer)

A field researcher is gathering data on the trunk diameters of mature pine and spruce trees in a certain area. The following are
lidiya [134]

Answer:

As the pvalue of the test is 0.02097 < 0.1, using a .10 significance level, he can conclude that the average trunk diameter of a pine tree is greater than the average diameter of a spruce tree.

Step-by-step explanation:

Using a .10 significance level, can he conclude that the average trunk diameter of a pine tree is greater than the average diameter of a spruce tree

The null hypothesis is that they are equal(that is, subtraction between the means is 0), while the alternate hypothesis is that they are greater(that is, subtraction between the means is larger than 0). So

H_0: \mu_1 - \mu_2 = 0

H_a: \mu_1 - \mu_2 > 0

In which \mu_1 is the mean pine trees height while \mu_2 is the mean spruce trees height.

The test statistic is:

z = \frac{X - \mu}{s}

In which X is the sample mean, \mu is the value tested at the null hypothesis and s is the standard error.

0 is tested at the null hypothesis:

This means that \mu = 0

Mean trunk diameter (cm) 35 30:

Pine trees - 35

Spruce trees - 30

The sample mean is given by the subtraction of the means. So

X = 35 - 30 = 5

Sample Size 40 80

Population variance 160 160

This means that the standard error for each sample is given by:

s_1 = \frac{\sqrt{160}}{\sqrt{40}} = 2

s_1 = \frac{\sqrt{160}}{\sqrt{80}} = \sqrt{2}

The standard error of the difference is the square root of the sum squared of the standard error of each sample.

s = \sqrt{2^2 + (\sqrt{2})^2} = \sqrt{6} = 2.4495

Test statistic:

z = \frac{X - \mu}{s}

z = \frac{5 - 0}{2.4495}

z = 2.04

Pvalue of the test:

Probability of a sample mean larger than 5, which is 1 subtracted by the pvalue of Z when X = 5.

Looking at the z-table, z = 2.04 has a pvalue of 0.9793.

1 - 0.9793 = 0.0207

As the pvalue of the test is 0.02097 < 0.1, using a .10 significance level, he can conclude that the average trunk diameter of a pine tree is greater than the average diameter of a spruce tree.

There are 40 nickels in a roll. If you have 250 rolls of nickels, how many nickels do you have?pls help me
gayaneshka [121]

Answer:

10,000 nickles

Step-by-step explanation:

Since there are 40 nickles in a roll and you have 250, think that you have 250 sets of 40. This means that this question is a multiplication problem.

Multiply 40 x 250. This would give you 10,000.

Don't forget units.
