4 0

Answer:

3\%

Step-by-step explanation:

we know that

The simple interest formula is equal to

I=P(rt)

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=8\ years\\ P=\$12,000\\I=\$2,880\\r=?

substitute in the formula above

2,880=12,000(8r)

Solve for t

2,880=96,000(r)

r=2,880/96,000

r=0.03

Convert to percent form

0.03*100=3\%

The average speed of a car driving down freeway is 70mph with a standard deviation of 5mph. Thid speed is normally distributed.
ikadub [295]

Answer:

0.081,0.2621,0.645,0.919

Step-by-step explanation:

Let X be the average speed of a car driving down freeway

Given that X is normal with mean as 70mph with a standard deviation of 5mph.

To convert to Z score we do

Z =\frac{x-70}{5}

a)  the probability that a randomly selected car is driving more than 77mph

=P(X>77)\\=P(Z>1.4)\\=0.081

b) probability that a randomly selected car is driving between 65 and 69 mph

= P(-1

c) the probability that a randonly selected car is driving between 67 and 77mph

=P(-0.6

d) the probability that a randomly selected car is driving less than 77mph

=P(Z

Begin by computing the <span>monthly interest rate like this:
</span>\frac{14.99}{12}=1.25
<span>Each month, we have to substract from $463 the monthly rate and the payment of 5%, which result in the following formula:
</span>463(1-(0.05+0.0125))^3=463\times0,9375^3\\=381.5

The drawing below (not to scale) shows a running track. The ends are semicircles. The distance between the two inner parallel st
aleksklad [387]
We are looking for the inner perimeter of the track. Since there are two semicircles, these mix to form one full circle so we can use the formula to find the circumference of the circle with a diameter of 60 m, which was given to us. With a diameter of 60m, the radius will be 30m. Now we can solve this problem.
C = 2πr
C = 2π(30)
C = 60π
The semicircle ends of the track are a distance of 60π m, and now we just need to add the lengths of the inner track which are 100 m each. So:
P = 60π + 100m + 100m
P = 200 + 60π
P = 388.5 m

A. 3<br> B. 1/3<br> C. -3<br> D. -1/3
guapka [62]

Answer:

D

Step-by-step explanation:

This is a negative slope since it is going from left to right so that leaves you with c or d.

The slope is rise over run so in this case the rise is 1 and the run is -3 since its going left.

This leads you to -1/3

Hope this helped :)
