Answer:

y = 6 when x = 18

Step-by-step explanation:

The appropriate formula for this direct proportion is y = kx, where k is the constant of proportionality.

We know y = 3 when x = 9:  3 = k(9)

This yields k = 3/9, or k = 1/3

Then the formula is y = (1/3)x

and when x = 18, y = (1/3)(18) = 6

y = 6 when x = 18

Mazyrski [523]

Answer:

84%

Step-by-step explanation:

The probability that the selected player is a football player, P(F)=19%

The probability that the selected player is a basketball player, P(B)=79%

The probability that the selected player play both football and basketball,

P(B \cap F)=14\%

We want to determine the probability that a randomly chosen athlete is either a football player or a basketball player, P(B \cup F)

In probability theory

P(B \cup F)=P(B)+P(F)-P(B \cap F)\\=79\%+19\%-14\%\\=84\%

The probability that a randomly chosen athlete is either a football player or a basketball player is 84%.

What’s the correct answer for this question?
irinina [24]

Answer:

A.

Step-by-step explanation:

Since VA and BC are equal in length so their central angles would also be equal.

So

<VWA = <BWC

32x-27 = 120

32x = 120+27

32x = 147

Dividing both sides by 32

x ≈ 4.6

Step-by-step explanation:

So squaring (i+7) looks like this

(i+7)^2

(i+7)(i+7)

Use foil.

First: i(i)=i^2=-1

Outer: i(7)=7i

Inner: 7(i)=7i

Last: 7(7)=49

____________Add the terms.
