ARea = area of square + area of semicircle

         = 26^2 + 0.5pi(13)^2

        = 941.46  square inches  to nearest hundredth

To find the area of the square, multiply the length and height(676 sq in). To find the semicircle square the radius (half the diameter) and multiply by 3.14 (or pi) Then divide by two. Giving you a total area of 941.33 sq inches.

f(x) = -9x^4 + 5x + 3\\\\ f(-x)= -9(-x)^4 + 5\cdot(-x) + 3=-9x^4-5x+3\\\\ f(-x)\not =f(x)\implies \text{ not even}\\\\ -f(x)=-( -9x^4 + 5x + 3)= 9x^4 - 5x - 3\\\\ -f(x)\not =f(-x) \implies \text{ not odd}

Write the domain as an inequality​
Pavlova-9 [17]

Answer:

x\leq 0

Step-by-step explanation:

The domain is the span of x-values covered by the graph.

From the graph, we can see that the x-values covered by the graph is all values to the left of zero including zero.

Therefore, the domain is all x-values less than or equal to 0:

x\leq 0

Further notes:

In interval notation, this is:

(-\infty,0]

Do one of the​ following, as appropriate.​ (a) Find the critical value z Subscript alpha divided by 2​, ​(b) find the critical v
aliya0001 [1]

Answer:

t=\pm 2.95

Step-by-step explanation:

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  

The t distribution or Student’s t-distribution is a "probability distribution that is used to estimate population parameters when the sample size is small (n<30) or when the population variance is unknown".

The shape of the t distribution is determined by its degrees of freedom and when the degrees of freedom increase the t distirbution becomes a normal distribution approximately.  

Data given

Confidence =0.99 or 99%

\alpha=1-0.99=0.01 represent the significance level

n =16 represent the sample size

We don't know the population deviation \sigma

Solution for the problem

For this case since we don't know the population deviation and our sample size is <30 we can't use the normal distribution. We neeed to use on this case the t distribution, first we need to calculate the degrees of freedom given by:

df=n-1=16-1=15

We know that \alpha=0.01 so then \alpha/2=0.005 and we can find on the t distribution with 15 degrees of freedom a value that accumulates 0.005 of the area on the left tail. We can use the following excel code to find it:

"=T.INV(0.005;15)" and we got t_{\alpha/2}=-2.95 on this case since the distribution is symmetric we know that the other critical value is t_{\alpha/2}=2.95
