A department store is holding a drawing to give free shopping sprees to two lucky customers. There are 17 customers who have ent
mixer [17]

Answer: Our required probability is 0.044.

Step-by-step explanation:

Since we have given that

Number of customers who have entered the drawing = 17

Number of customers live in the town of Gaston = 5

Number of customers live in Pike = 4

Number of customers live in Wells = 8

The first customer will be selected and then second customer will be selected from the remaining .

Probability of getting first customers are Pike residents = \dfrac{4}{17}

Probability of getting second customers are Pike residents = \dfrac{3}{16}

So, the probability that both customers selected are Pike residents are

\dfrac{4}{17}\times \dfrac{3}{16}\\\\=0.044

Hence, our required probability is 0.044.

Lisa wrote the expression (3x + 6x) - 2(x + 1) + 5. She simplified the expression using the following steps:
Ivanshal [37]

Answer:

Step 1. Should be 3(x +2x) -2(x +1) +5 . . .

or . . . 3x(1 +2) -2(x +1) +5 . . .

or . . . 9x -2(x+1) +5

Step-by-step explanation:

Lisa apparently failed to realize that both terms inside the first set of parentheses have 3x as a factor. They are like terms, so could be combined directly. If Lisa really wants to factor out 3 or 3x, she could do so and then combine the remaining factors at another step.
