Answer:

The correct option is B.

Step-by-step explanation:

A plane extends infinitely in two dimensions. It has no thickness.The plane has two dimensions: length and width. But since the plane extends infinitely,the length and width cannot be measured.

Lets take an example of a flat sheet of metal. Imagine a flat sheet of metal. Now make it infinitely large in both directions. This means that no matter how far you go, you never reach its edges. Now imagine that it is so thin that it actually has no thickness at all. In spite of this, it remains completely rigid and flat. This is the 'plane' in geometry.

Conan O'Brien hosts the Conan show and Andy Richter, his sidekick, writes for it. Conan needs 4 hours to rehearse and host a goo

andrew-mc [135]

Answer:

Step-by-step explanation:

1. Conan needs 4 hours to rehearse and host a good show. Andy needs 10 hours to do the same. So, Cohan needs 6 hours less than Andy to rehearse and host a good show. This means Cohan has an absolute advantage in the production of show hosting.

2. Conan writes one usable joke in an hour, Andy needs 2 hours to do the same. So, Cohan has an absolute advantage in the production of joke writing.

Thus, Cohan has an absolute advantage in the production of both show hosting and joke writing.

Correct option is option C.

I think the best value for x is -9 because 6 x -9 = 54, minus 8 equals -44.

Let f(x) = x2 − 8x + 5. Find f(−1)

rewona [7]

Answer:

Step-by-step explanation:

$f(x)=x^2-8x+5$

now substitute x for -1

$f(-1)=(-1)^2-8(-1)+5$

now solve

$f(-1)=1+8+5$

$f(-1)=14$

there is your answer! hope this helps! :)

liberstina [14]

Answer:

Step-by-step explanation:

Hello!

You have two populations of interest and want to compare them. If you define the study variables as:

X₁: average hourly wages of an employee of the Downtown store.

n₁= 25

X[bar]₁= $9

S₁= $2

X₂: average hourly wages of an employee of the North Mall store.

n₂= 20

X[bar]₂= $8

S₂= $1

Both samples taken are independent, assuming that both populations are normal and that their population variances are equal I'll use the Student's-t statistic with a pooled sample variance to calculate the Confidence interval:

95% CI for μ₁ - μ₂

(X[bar]₁-X[bar]₂) ± $t_{n_1+n_2-2; 1-\alpha /2} * (Sa*\sqrt{\frac{1}{n_1} +\frac{1}{n_2} } )$
