Answer:
the average change in stock prices over the two days is -155
Step-by-step explanation:
The computation of the average change in stock price over the two days is shown below:
= (-One day points - second day points) ÷ number of days
= (-250 points - 60 points ) ÷ 2 days
= -310 points ÷ 2 days
= -155
Hence, the average change in stock prices over the two days is -155
We simply applied the above formula so that the average change could come
Answer:
Step-by-step explanation:
arithmetic sequence: 60,68,76,......
a = 60
d = 68 - 60 = 8
an = a + (n-1)*d
a20 = 60 + 19 * 8
= 60 + 152
= 112
There are 112 seats in the 20th row
Answer:
The answer to your question is Midpoint = (0, 1)
Equation of the bisector y = 2x + 1
Step-by-step explanation:
Data
P (-4, 3)
Q (4, -1)
Process
1.- Find the midpoint
Xm = (-4 + 4)/2
Xm = 0/2
Xm = 0
Ym = (3 - 1)/2
Ym = 2/2
Ym = 1
Midpoint = (0, 1)
2.- Equation of the line
slope = (-1 - 3) / (4 + 4)
= -4/8
= -1/2
But the new line is perpendicular so the new slope is
m = 2
Equation of the new line
y - y1 = m(x - x1)
y - 1 = 2(x - 0)
y - 1 = 2x
y = 2x + 1
Answer:
12.486 Rounded to the Nearest Whole Number
To round 12.486 to the nearest whole number consider the tenths' value of 12.486, which is 4 and less than 5. Therefore, we have to round down: the whole number ones place value of 12.486, 12, remains 12, and the decimal point and all digits (. 486) are removed.
Step-by-step explanation:
Answer:
3.5 inches
Step-by-step explanation:
create a proportion:
inches / miles = inches / miles
let 'x' = distance in inches
<u>1/4</u> = <u> x </u>
18 252
18x = 252(1/4)
18x = 63
x = 63 / 18
x = 3.5
