A used car has a value of $15,250 when it is purchased in 2012. The value of the car decreases at a rate of 7.5% per year.

1 answer:

3 0

The given P=15250
r=7.5/100=0.075 
t=x 
y = 15250*(1 - 0.075)^x 
after 8 years we would have 
x = 8 
y = 15250*(1 - 0.075)^8 
y = $8,173.42 
after 8 years the value of the car would be $8,173.42

An angle measures 10° less than the measure of its complementary angle. What is the measure of each angle?

Wewaii [24]

Answer:

50º & 40º

Step-by-step explanation:

complementary anlges add up to 90º. so, we can make an equation:

x+x-10=90

2x=100

x=50

so the angles are 50º and 40º.

At a fast food restaurant, customers are asked if they want to “round up” their bill to the next highest dollar and donat

jarptica [38.1K]

Answer:

(a) 0.1414

(b) 0.1010

Step-by-step explanation:

(a)

The density curve is rectangular in shape.

This implies that the distribution of donations is Uniform.

(b)

Compute the probability of donations at least 85 cents as follows:

$P(X\geq 85)=\int\limits^{99}_{85} {\frac{1}{99-0} \, dx$

$=\frac{1}{99}\times [x]^{99}_{85}\\\\=\frac{99-85}{99}\\\\=0.1414\\\\$

Thus, the proportion of donations that are at least 85 cents is 0.1414.

(b)

Compute the probability of donations between 30 and 40 cents as follows:

$P(30\leq X\leq 40)=\int\limits^{40}_{30} {\frac{1}{99-0}} \, dx$

$=\frac{1}{99}\times [x]^{40}_{30}\\\\=\frac{40-30}{99}\\\\=0.1010$

Thus, the probability of donations between 30 and 40 cents is 0.1010.
