ipn [44]

Answer:

a = length

b = height(width)

a=3b

2(a+b)=120

2(b+3b)=2(4b)=8b

8b=120

b=15

a=45

length is 45 feet

width is 15 feet

Rochelle can run 800 meters in 5 minut

Semmy [17]

To find how much she can run in one minute we’re going to divide 800 by 5, to which we get 160.

She runs 160 meters in one minute.

We want to know how many meters she can run in 9 minutes.

160 * 9 = 1,440

She can run 1,440 meters in 9 minutes.

Given P(E)= 0.24 and P(FnE)= 0.17, find P(F| E). Round the answer to the nearest hundredth. A. 029 B. 0.40 C. 0.71 D. 1.41

romanna [79]

Given P(E) = 0.24 and P(F ∩ E) = 0.17

It says to find conditional probability of F given E has occurred.

We know the formula of conditional probability is given by :-

P(F ║ E) = $\frac{P(E\;and\; F)}{P(E)}$

P(F ║ E) = $\frac{0.17}{0.24}$ = 0.708333

P(F ║ E) = 0.71

Hence, option C i.e. 0.71 is the final answer.

Nezavi [6.7K]

ANSWER

$(x + 2)(3x + 4)$

EXPLANATION

The given expression is

$3x(x + 2) + 4(x + 2)$

We can see that (x+2) is the greatest common factor.

We factor to obtain;

$(x + 2)( 3x + 4)$

The correct choice is C.
