Cosine and secant functions are reciprocal, which means

$\mathsf{sec\,\theta=\dfrac{1}{cos\,\theta}}$

So, if $\mathsf{cos\,\theta=\dfrac{3}{8},}$ then

$\mathsf{sec\,\theta=\dfrac{1}{~\frac{3}{8}~}}\\\\\\
\mathsf{sec\,\theta=\dfrac{8}{3}\qquad\quad\checkmark}$

I hope this helps. =)

Let f be defined as shown.<br> What is f^-1(8)?

Gnoma [55]

Answer:

From the picture when the input of f(x) is 6 the output is 8

So it's just the reverse f^-1(8) when the input is 8 the output is 6

So f^-1(8) = 6

Hope this helps you

(20 points) A statistics practitioner calculated the mean and the standard deviation from a sample of 400. They are x = 98 and s

Nimfa-mama [501]

Answer:

The P-value is 0.0234.

Step-by-step explanation:

We are given that a statistics practitioner calculated the mean and the standard deviation from a sample of 400. They are x = 98 and s = 20.

Let = population mean.

So, Null Hypothesis, : = 100 {means that the population mean is equal to 100}

Alternate Hypothesis, : > 100 {means that the population mean is more than 100}

The test statistics that will be used here is One-sample t-test statistics because we're yet to know about the population standard deviation;

T.S. = ~

where, = sample mean = 98

s = sample standard deviation = 20

n = sample size = 400

So, the test statistics = ~

= -2

The value of t-test statistics is -2.

Now, the P-value of the test statistics is given by;

P( < -2) = 0.0234 {using the t-table}
