5 0

For this case we must find an expression equivalent to:

10q-30

We look for the factors of 10 and 30:

10: 1,2,5,10

30: 1,2,3,5,6,10,15,30

The greatest common factor of both numbers is 10.

Then, we can rewrite the expression as:

10 (q-3)

Answer:

10 (q-3)

12=10(s+4)+50 what is the written problem to this can you help me with the answer
muminat

Answer:

s = -7.8

Step-by-step explanation:

from the question 12=10(s+4)+50

<u>first step</u>

open the bracket and evaluate for the value of s

12=10(s+4)+50

12 = 10s + 40 + 50

12 = 10s + 90

collect or combine the like terms

12-90 = 10s

-78 = 10s

divide both side by 10

-78/10 = 10s/10

-7.8 = s

therefor s = -7.8

Suppose that the probabilities of a customer purchasing​ 0, 1, or 2 books at a book store are 0.4​, 0.2​, and 0.4​, respectively
Volgvan

Answer:

Expected number of books = 1.0

Step-by-step explanation:

Expected number of books, E(x) = ∑xp(x)

∑ = Summation

x = books

p(x) = probability of purchasing a book

E(x) = (0*0.4) + (1*0.2) + (2*0.4)

E(x) = 0 + 0.2 + 0.8 = 1.0
