This is just simple division.

5.5 * 10^16
——————
5.5 * 10^8

The 5.5’s cancel out leaving 10^16/10^8

Exponents subtract when you divide like terms. So the answer is #1. It’s not #2 because that is 10^7

Which of the following approaches cannot be used to perform a two-tailed hypothesis test about μ?
Burka [1]

Answer:

Option a)  Compare the level of significance to the confidence coefficient.

Step-by-step explanation:

We are given the following information in the question:

We are performing a two-tailed test hypothesis. We can follow the following approaches:

Option a)  Compare the level of significance to the confidence coefficient.

This cannot be used to perform hypothesis.

Option b) Compare the value of the test statistic to the critical value.

If the test statistic lies in the acceptance region evaluated by the critical value, we accept the null hypothesis. If not, we reject the null hypothesis.

Option c) Compare the confidence interval estimate of μ to the hypothesized value of μ.

If the estimated population lies in the calculated confidence interval, we accept the null hypothesis otherwise, we reject the null hypothesis.

Option d) Compare the p-value to the value of α.

If the p-value is greater than the significance level, we accept the null hypothesis. If it is lower than the significance level, we reject the null hypothesis.

the radius of the inner white circle of the doughnut is 2cm. The circumference of the outer edge of the doughnut is 43.96cm. Wha
Elenna [48]

Answer:

141.4 sq cm

Step-by-step explanation:

to find the area of the outer circle with a smaller circle inscribed within, you find the area of each and subtract the smaller area from the larger

the radius of the smaller circle is 2

we have to find the radius of the larger circle so we use what we know about its circumference:

C = 2πr

43.96 = 2πr

21.98 = πr

21.98 / π = r

r ≈ 7 cm

now use r = 7 to find area of larger circle:

A = πr²

A = π49

Area of smaller circle:  4π

Area of larger circle without including inner section is 49π - 4π = 45π

45π ≈ 141.4 sq cm

(3x2 – 2) + (2x2 - 6x + 3)<br> Simplified?
vlabodo [156]

Answer:

3x^2-2+2x^2-6x+3=5x^2-6x+1

Factor: 5x^2-5x-x+1=5x(x-1)-1(x-1)=5x-1(x-1)

Step-by-step explanation:

If you have answer choices, the answer would be 5x2 − 6x + 1.

How do i find the y-intercept for f(x)=|x|-5
wel
The y-intercept for f(x)=|x|-5 is (-5). Just look at the function as slope-intercept form and find the number that is not being multiplied by x. That number will usually be your y-intercept.
