Answer:
It’s the third choice : x ≥8
Step-by-step explanation:
the third choice means he made equal to or greater than $8 an hour.
185-25=160
160÷20=8
Answer:
The ordered pair solution is (-2, 8)
Step-by-step explanation:
y = -4x ------ equation 1
y = 2x + 12 ---- equation 2
We solve for x by substitution;
Substituting the value of y into equation 2;
y = 2x + 12
-4x = 2x + 12
-4x -2x = 12
-6x = 12
Divide by -6
x = 12/(-6)
x = -2
From equation 1;
y = -4x
Substituting the value of x;
y = -4×(-2)
y = 8.
PROOF;
y = -4x
8 = -4*(-2)
8 = 8
The probability of getting 3 or more who were involved in a car accident last year is 0.126.
Given 9% of the drivers were involved in a car accident last year.
We have to find the probability of getting 3 or more who were involved in a car accident last year if 14 were selected randomly.
We have to use binomial theorem which is as under:
n
where p is the probability an r is the number of trials.
Probability that 3 or more involved in a car accident last year if 14 are randomly selected=1-[P(X=0)+P(X=1)+P(X=2)]
=1-{
}
=1-{1*0.2670+14!/13!*0.9*0.29+14!/2!12!*0.0081*0.2358}
=1-{0.2670+0.3654+0.2358}
=1-0.8682
=0.1318
Among the options given the nearest is 0.126.
Hence the probability that 3 or more are involved in the accident is 0.126.

Answer:
c = +5 or c= -5, both are possible
Step-by-step explanation:
3^2 = 9
4^2 = 16
c^2 = 25
c = + or - sqrt(25)
c = + 5 or -5
