The graph shows that the function is equal to y = 2cos(3x) + 1 because in the graph I notice that the table is (0, 3), (60°, -1), and (120°, 3). It shows that a is equal to 2, b is equal to 3, and c is equal to -1, making the function equal to y = 2cos(3x) + 1

a = 2
b = 3
c = 1

The radius of a large sphere is 8 times the radius of a small sphere. the surface area of the large sphere is how many times the
kondaur [170]
Large sphere's radius = R,
small sphere's radius = r, R = 8r
surface area of a sphere (SA) = 4×pi×radius^2
So what we need is the SA of the larger in terms of the smaller sphere, so if:
SA (of R) = 4×pi×R^2, then plug in "8r" for "R"...
SA = 4×pi×(8r)^2 = 4×3.14×64r^2
SA = 12.57×64r^2 = 804 r^2
Therefore the SA of the larger sphere is 804 times the SA of the smaller sphere.
I hope that makes sense!

According to the United States Census Bureau, the average single-family home constructed in 2016 was 2,463 square feet. Carmen w
Dimas [21]

Using the t-distribution, it is found that the value of the test statistic is t = -87.3.

At the null hypothesis, it is <u>tested if the mean is of 2,463 square feet</u>, that is:

H_0: \mu = 2463

At the alternative hypothesis, it is <u>tested if the mean is smaller</u>, that is:

H_1: \mu < 2463.

We have the <u>standard deviation for the sample</u>, hence, the <em>t-distribution</em> is used to solve this question.

The test statistic is given by:

t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}

The parameters are:

  • \overline{x} is the sample mean.
  • \mu is the value tested at the null hypothesis.
  • s is the standard deviation of the sample.
  • n is the sample size.

The values of the <em>parameters </em>are: \overline{x} = 1640, \mu = 2463, s = 66, n = 49.

Hence, the value of the <em>test statistic</em> is:

t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}

t = \frac{1640 - 2463}{\frac{66}{\sqrt{49}}}

t = -87.3
