Answer:
c. 106 million
Step-by-step explanation:
A = number of people in the sample that use public transportation 5 or more days per week
A = 2,067,153
B = number of people total in the sample
B = 4,295,280
C = proportion of those in the sample that use public transportation 5 or more days per week
C = A/B
C = (2,067,153)/(4,295,280)
C = 0.48126 approximately
Multiply this value by the figure 220 million to compute the estimated number of people who use public transportation 5 or more days per week
C*(220 million) = 0.48126*(220 million) = (0.48126*220) million = 105.8772 million = 106 million
Answer:
(x-5)(x+1)
Step-by-step explanation:
Since the highest power of x is 2, u can assume the equation to be (x +/- A) (x +/- B), whereby A and B are unknowns.
Since the coefficient of X^2 is 1, and the number in the equation is - 5, the only possible values for A and B to get - 5 is either - 5 and 1 or 1 and - 5.
Since coefficient of x is - 4 and number in equation is - 5, imagine inserting those numbers in the equation and cross multiplying back. You would realise that the answer should be as listed above.
Answer:
5v+4
Step-by-step explanation:
Answer:
$85
Step-by-step explanation:
$25 + $80 + $65=$180
$180 - $80 -$15 = 85
So balance would be $85
