Answer:
No solution.
Step-by-step explanation:
−3> 7x−8 > −0.2
Split this into 2 inequalities:
7x - 8 < -3 Add 8 to both side:
7x < 5
x < 5/7.
and:
7x - 8 > -2 Add 8 to both sides:
7x > 6
x > 6/7.
But x cannot be both less than 5.7 and > 6.7, so No solution.
Answer:
Sequence One
Step-by-step explanation:
S = a₁ / (1 − r) is the infinite sum of a geometric series where |r| < 1.
Sequence One: r = 1/5
Sequence Two: r = 2
Sequence Three: not geometric
Sequence Four: r = -3/2
Only Sequence One has |r| < 1.
Answer: Hello your question is incomplete below is the missing part of the question
The Bureau of the Census reports that the median family income for all families in the United
States during the year 2003 was $43,318. That is, half of all American families had incomes exceeding this amount, and half had incomes equal to or below this amount. Suppose that four families are surveyed and that each one reveals whether its income exceeded $43,318 in 2003.
answer :
P(A) = 11 / 16
P(B) = 3/8
and P(C) = 1/4
Step-by-step explanation:
Making use of the given interpretation for the median we can assign probabilities to simple events as
P(A) = | A | / | sample space |
where | A | = 11
sample space = 16
P(A) = 11 / 16
∴ P(B) = 6/16 = 3/8
and P(C) = 4/16 = 1/4

Answer:
Step-by-step explanation:
At first you need to turn roots into factors and then multiply the
then you have
f(x) = a(x + 2)(x -5)^2
f(x) = a(x + 2)(x^2 - 10x + 25)
f(x) = a(x^3 - 8x^2 + 5x + 50)
You can use either synthetical or the factor
theorem
f(-2) = a(-8 - 8(4) + 5(-2) + 50) = a(0) = 0.. check, f
=-2
€(5) = a(125 - 8(25) + 5(5) + 50) = a(0) = 0 check, f
= 5 works
Then divide it to the the second multi
And you should get x^2 - 3x - 10 = (x - 5)(x + 2),
where the other two zeros are X =5 , and x=-2
