Anit [1.1K]

Since we must save 50 meals for volunteers, the real amount we are giving away is 700 meals in 12 hours.

700/12 = 58.3333...

10*58.333.. = 583.333....

Since we can't serve 1/3 of a person, we take 583. Hope this helps!

A manager records the number of hours, X, each employee works on his or her shift and develops the probability distribution belo

Reika [66]

Answer:

c. 2

Step-by-step explanation:

Given : X = No. of hours worked

No. of people work for the manager = 50

X = 3, 4 , 5 , 6 , 7, 8

P(X) = 0.1 , ? , 0.14 , 0.3 , 0.36 , 0.06

To Find : No. of people work for four hours

Solution : First understand the fact that sum of all probabilities is equal to 1

So, sum of all values of P(X) = 1

⇒ $0.1+?+0.14+0.3+0.36+0.06 = 1$

⇒ $0.96+? = 1$

⇒ $?= 1-0.96$

⇒ $? = 0.04$

So, the probability of no. of people worked for 4 hours is 0.04.

⇒P(4)=0.04

Thus , To calculate no. of people work for four hours :

$0.04\times 50$

⇒ 2 no. of people work for four hours per shift .

99 pencils cost \$7.74$7.74dollar sign, 7, point, 74. Which equation would help determine the cost of 666 pencils? Choose 1 answ

balu736 [363]

Answer:

$\large \boxed{\text{A) } \dfrac{6}{x} = \dfrac{9}{\$7.74}}$

Step-by-step explanation:

9 pencils cost $7.74

6 pencils cost x

The ratios are

$\dfrac{9}{6} = \dfrac{\$7.74}{x}$

According to the alternendo property,

$\dfrac{9}{6} = \dfrac{\$7.74}{x} \Rightarrow \dfrac{9}{\$7.74} = \dfrac{6}{x}\\\\\text{The correct answer is $\large \boxed{\mathbf{ \dfrac{6}{x} = \dfrac{9}{\$7.74}}}$}$
