Point slope form = y - b= m ( x - a )
where y and x stay the same
m is the slope
and (a, b) (any coordinate on the graph)
based on the point (5, -7)
Y - (-7) = -3 (x - 5)
however, the - cancels out the negative 7 making I positive
Y + 7 = -3(x - 5)
Answer:
x = 80
Step-by-step explanation:
1x + 0.2x = 96
1.2x = 96
Divide both sides by 1.2
x = 80
It would be 100. If you divide 100/10, you get 10, multiply that by 9 and you’d get 90.

Answer:
a) 
b) P(x>2) = 0.566
c) P(2<x<5) = 0.334
Step-by-step explanation:
Given 24% of U.S. adults say they are more likely to make purchases during a sales tax holiday
Probability 0f U.S. adults say they are more likely to make purchases during a sales tax holiday (p) = 0.24
n = 10
By using Poisson distribution
mean number of make purchases during a sales tax holiday
λ = np = 10 X 0.24 = 2.4
a)
The probability of getting exactly '2'
The probability 


b) The probability of getting more than '2'


= 0.090 + 0.2177+0.261 = 0.566
P(x>2) = 0.566
c) The probability of getting between two and five
P( 2<x<5) = P(x=3)+p(x=4) =
P(2<x<5) = 0.2090 + 0.125 = 0.334
