Slope formula (m = slope):

y₂ - y₁

m = ----------

x₂ - x₁

Coordinates:

(5, 1)

(5, -2)

Solve by substitution:

-2 - 1

m = ---------

5 - 5

-3

m = ----

m = ∞

This is true because, when y₁ ≠ y₂ and x₁ = x₂, the slope is ∞ (infinity).

Hope this helps!

To the nearest whole percent, what is the probability that a randomly chosen member of the JV swim team does not wear glasses an

Yuri [45]

Answer: 14%

Step-by-step explanation:

Complete question is provided in the attachment below:

Probability that members of the junior varsity swim team wear glasses = 55%=0.55

Given: P(wear glasses) = 0.55

P(not wear glasses) = 1-0.55 = 0.45

P(member in 10th grade | not wear glasses) = 30%

Using conditional probability formula:

$P(B|A)=\dfrac{P(A\text{ and } B)}{P(A)}$

$\Rightarrow\ 0.30=\dfrac{P(\text{not wear glasses and in 10th grade})}{0.45}\\\\\Rightarrow\ P(\text{not wear glasses and in 10th grade})=0.45\times0.30\\\\0.135=13.5\%\approx14\%$

Hence, the probability that a randomly chosen member of the JV swim team does not wear glasses and is in the 10th grade = 14%.

So, the correct option is "14%".

Flauer [41]

Answer:

x<-1

Step-by-step explanation:

All of the numbers on/in the set are below -1. That means for that any of them to be x, the inequality would be x<-1.

Please evaluate P(7,1)

xxTIMURxx [149]

Answer:

Step-by-step explanation:

Using the definition

n $P_{r}$ = $\frac{n!}{(n-r)!}$

where n! = n(n - 1)(n - 2)..... 3 × 2 × 1

Then

7 $P_{1}$ = $\frac{7!}{(7-1)!}$ = $\frac{7!}{6!}$ ← cancel out the multiples 6 ×5 × 4 × 3 × 2 × 1 , then

7 $P_{1}$ = 7
