Five-sevenths of a number is -35. what is the number?

White raven [17]

So lets write this equation out. Let x be that number we are trying to find.

So five-sevenths is a fraction that is written like this

5/7

when you see the word "of" that means multiplication

so we can write the full equation.

(5/7)x = -35

now we can solve

Multiply both sides by 7

5x = -245

now divide by 5
and we get

x = -49

In the town of Maplewood a certain type of DVD player is sold at just two stores, 43% of the sales 13) are from store A and 57%

umka21 [38]

Answer:

Option A 0.312 is right

Step-by-step explanation:

Given that iN Maplewood a certain type of DVD player is sold at just two stores, 43% of the sales 13) are from store A and 57% of the sales are from store B. 2.4% of the DVD players sold at store A are defective while 4.0% of the DVD players sold at store B are defective.

Prob for any random item form store to be defective = Prob from A and defective +Prob from B and defective

= $0.43(0.024)+0.57(0.04)\\=0.03312$

Prob it came from A and defective = 0. $0.43(0.024)=0.01032$

If Kate receives one of these DVD players as a gift and finds that it is defective, what is the probability that it came from store A

= $\frac{0.01032}{0.03312} \\=0.312$
