Question 1 is no doubt B, because Johnny only asked the students in his science class, not the entire school's population. As for question 2, If you could give me a picture of the actual graph, that would be fantastic. Until then, i don't think I can answer Q2 properly.

Question 1 is D.<em> </em>

It's not clear that the science class is a good sample of the school as a whole. It may be an elective or for a particular grade, making it a biased sample.

For Question 2 I'll try to create the histogram from your description.

N TOP BOTTOM

9 3 3

10 5 4

11 2 3

If that's accurate the BOTTOM, B, group has longer arms, due to a single person measuring 11 instead of 10.

Neither B or D is really a good answer making me think I transcribed the table incorrectly. I'd guess D

Andrew has a different cookie recipe that makes 28 cookies. He plans to have 21 guests at the party and wants each guest to have

joja [24]

Answer: Since each recipe makes 28 cookies, tripling the recipe would give him 28(3) = 84 cookies.

Step-by-step explanation: <em>Since each recipe makes 28 cookies, tripling the recipe would give him 28(3) = 84 cookies. </em>

<em> </em>

<em>Then divide the total number of cookies by the number of guests: 84 21 = 4. Each person would get 4 cookies.</em>

<em> </em>

<em>This process can be modeled by the expressions 28(3) ÷ 21 and </em>

<em>28(3) </em>

<em>21 </em>

<em>. This is because the fraction bar represents division.</em>

Let f(x) = (x − 3)−2. Find all values of c in (1, 7) such that f(7) − f(1) = f '(c)(7 − 1). (Enter your answers as a comma-separ

Sidana [21]

Answer:

This contradicts the Mean Value Theorem since there exists a c on (1, 7) such that f '(c) = f(7) − f(1) (7 − 1) , but f is not continuous at x = 3

Step-by-step explanation:

The given function is

$f(x)=(x-3)^{-2}$

When we differentiate this function with respect to x, we get;

$f'(x)=-\frac{2}{(x-3)^3}$

We want to find all values of c in (1,7) such that f(7) − f(1) = f '(c)(7 − 1)

This implies that;

$0.06-0.25=-\frac{2}{(c-3)^3} (6)$

$-0.19=-\frac{12}{(c-3)^3}$

$(c-3)^3=\frac{-12}{-0.19}$

$(c-3)^3=63.15789$

$c-3=\sqrt[3]{63.15789}$

$c=3+\sqrt[3]{63.15789}$

$c=6.98$

If this function satisfies the Mean Value Theorem, then f must be continuous on [1,7] and differentiable on (1,7).

But f is not continuous at x=3, hence this hypothesis of the Mean Value Theorem is contradicted.
