Answer: 5%
Step-by-step explanation:
A meteorologist predicted that Monday's hight temperature would be 76F and on Monday, the temperature reached 80F.
The percentage error will be
Percentage error=
(Exact value-Forecasted value)/exact value x 100
= 76-80/80 × 100
= -4/80 × 100
=4/80 × 100
= 400/80
= 5%
The percentage error is 5%.

Answer:
First one: C. Second One:C.
Step-by-step explanation:
Kate purchased a car for $23,000. It will depreciate by a rate of 12% a year. What is the value of the car in 4 years?
a) $13,935.76
b) $12,874.57
c) $13,792.99
To solve this this is an exponential function. The price started at $23,000 and depreciates at 12% so the equation is f(x) = (23,0000)(1-0.12)^4. When calculated results with 13792.99328 which is C.
A rare coin is currently worth $450. The value of the coin increases 4% each year. Determine the value of the coin after 7 years.
a) $613.98
b) $546.78
c) $592.17
To solve this this is also an exponential function. The price started at $450 and the coin increases 4% each year so the equation is f(x) = (450)(1+0.04)^7. When calculated results with 592.169300656 which is c.
Answer:
The ordered pair is a solution.
Step-by-step explanation:
Plug x = -3 and y = 0 into the 2 inequalities and see if they fit:
-2x + 2y >= 4
-2(-3) + 2(0) = 6 which is > 4 so this one fits.
y>= 2x - 6
0 >= 2*-3) - 6 = -12 which also fits.
