Answer: As the time spent training increases, the time to run 100m decreases.

Step-by-step explanation:

The scatterplot shows a negative correlation. Thus, as x increases, y decreases. Since x is training time and y is 100m time, the second option would be the appropriate response.

At Central High School, the following probabilities have been determined.

yuradex [85]

Answer:

The expression is $\frac{h}{g}$

Step-by-step explanation:

Define the following events:

A: The student is enrolled in a foreign language class,

B: The student is enrolled in a technology class

We are given that $P(A) = f, P(B) = g, P(A\cap B) = h$

Recall the definition of conditional probability: Let A, B be sets if P(B)>0, then, the probability of A given B is given by the expression

$P(A|B) = \frac{P(A\cap B)}{P(B)}$

So, using this, we are asked for the probability $P(A|B)$ which is

$P(A|B) = \frac{P(A\cap B)}{P(B)} = \frac{h}{g}$

What is the value of this expression when a = 3 and b = -2?

weqwewe [10]

The first step: Simplify the expression with:

$\dfrac{x^n}{x^m}=x^{n-m}\\\\(xy)^n=x^ny^n\\\\(x^n)^m=x^{nm}\\\\x^{-n}=\dfrac{1}{x^n}$

$\left(\dfrac{3a^{-2}b^6}{2a^{-1}b^5}\right)^2=\left(\dfrac{3}{2}a^{-2-(-1)}b^{6-5}\right)^2=\left(\dfrac{3}{2}a^{-1}b^1\right)^2\\\\=\left(\dfrac{3}{2}\right)^2(a^{-1})^2b^2=\dfrac{9}{4}a^{-2}b^2=\dfrac{9b^2}{4a^2}$

The second step: Put the values of a = 3 and b = -2 to the expression:

$\dfrac{9(-2)^2}{4(3)^2}=\dfrac{(9)(4)}{(4)(9)}=1$
