It said the greatest amount,
So change 50% to .50
120x.50=60
Answer:
(a). $35746. (b). Higher.
Step-by-step explanation:
(a). Given that the least-squares regression equation is y = 7163x + 14242. Also, in the question above we are given that y is the median income and x is the percentage of 25 years and older with at least a bachelor's degree in the region, that is to say that the value of x = 30.
Therefore, y = 7163x + 14242.
y = (7163 × 30) + 14242.
y = $35746.
(b). The condition for our x is; 28.7 percent of adults 25 years and older have at least a bachelor's degree.
Then, y = (7163 × 28.7) + 14242.
y = $34814.
Hence, we have the median income in this region = $38,163 HIGHER than $34814.
Answer:
a/b = 2
so , a = 2b
b/c = 3/4
so , c = 4b/3
c/a = (4b/3) / 2b
which gives 2/3
Step-by-step explanation:
The value of c that makes up a perfect square trinomial is
9x^2 - 12x +c
