The sales tax in one town is 8%, So, the total cost of an item can be written as c + 0.08. What is the total cost of an item tha

JulsSmile [24]

First you would want to figure out how much tax would be

127 × 0.08 = 10.16

Then you add the tax to the original price

10.16 + 127 = 137.16

And now you have the total cost of the product

Answer: The critical value of the test is 2.807.

Step-by-step explanation:

Since we have given that

n = 24

So, the degree of freedom v = n-1 = 24 - 1=23

Since, n>30, so we will use 't-test'.

Here, α = 0.01

so, According to t-table, we get that

$t_{\alpha ,v}=t_{0.01,23}=2.807$

If we take α, then we are taking about two tail test.

If we take $\dfrac{\alpha }{2}$ then we are talking about one tail test.

But in both the cases, the result will be same.

Hence, the critical value of the test is 2.807.

Burka [1]

Answer:

530 in ^2

Step-by-step explanation:

The figure given is a triangle

We use the formula for the area of a triangle

A = 1/2 bh where b is the length of the base and h is the height

The height is perpendicular to the base( at 90 degrees)

A = 1/2 ( 26.5) * ( 40)

= 530 in ^2
