Five times the smallest of three consecutive odd integers is seven more than twice

Fantom [35]

Answer:

5, 7, 9

Step-by-step explanation:

Using the information given we get:

$5x-7=2z$

$x+2=y\\y+2=z\\x+4=z$

$5x-7=2(x+4)\\5x-7=2x+8\\$

Add 7 to both sides

$5x=2x+15$

Subtract 2x from both sides

$3x=15$

Divide both sides by 3

$x=5$

Using these equations:

$x+2=y\\y+2=z\\x+4=z$

and

$x=5$

We get:

$x=5\\y=7\\z=9$

Of all customers purchasing automatic garage-door openers, 70% purchase a chain-driven model. Let X = the number among the next

otez555 [7]

Answer:

P(X > 10), n = 15, p = 0.7

P(X > 10) =P(10 < X ≤ 15) = P(11 ≤ X ≤ 15) = P(X = 11, 12, 13, 14, 15)

=P(X = 11) + P(X =12) + P(X = 13) + P(X =14) + P(X = 15) (because these are disjoint events)
