Answer:

Step-by-step explanation:

The volume (V) is calculated as

V = area of triangular face × depth

Area of triangle = $\frac{1}{2}$ bh ( b is the base and h the height )

Here b = 3 and h = 4 , then

A = $\frac{1}{2}$ × 3 × 4 = 6 Km²

Now depth = 2, thus

V = 6 × 2 = 12 Km³ → B

Answer:

The 95% confidence interval for the true average strain is between 23.94% and 28.06%.

Step-by-step explanation:

We have the standard deviation of the sample, so we use the t-distribution to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 13 - 1 = 12

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 12 degrees of freedom(y-axis) and a confidence level of $1 - \frac{1 - 0.95}{2} = 0.975$ . So we have T = 2.18

The margin of error is:

$M = T\frac{s}{\sqrt{n}} = 2.18\frac{3.4}{\sqrt{13}} = 2.06$

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 26 - 2.06 = 23.94

The upper end of the interval is the sample mean added to M. So it is 26 + 2.06 = 28.06

The 95% confidence interval for the true average strain is between 23.94% and 28.06%.

Which equation represents a tangent function with a domain of all Real numbers such that x is not equal to pi over 2 plus pi tim

Rudik [331]

The equation that represents a tangent function with a domain of all real numbers such that $x \ne \frac{\pi}2 + n \pi$ is $g(x) = \tan(n \pi - \frac{\pi}2)$

<h3>Domain</h3>

The domain of a function is the set of input values the function can take

The domain of the function is given as:

$x \ne \frac{\pi}2 + n \pi$

<h3>Undefined function</h3>

This means that, we determine the function that would be undefined when the input value equals

$x = \frac{\pi}2 + n \pi$

From the list of given functions, only function g(x) is undefined at $x = \frac{\pi}2 + n \pi$

Hence, the tangent function is $g(x) = \tan(n \pi - \frac{\pi}2)$
