Answer: its is you figer it out okay haha

Step-by-step explanation: im jokeing

Kinetic energy = 1/2 M V2

At the lower speed, the car's KE is (500) (1)2 = 500 joules

At the higher speed, the car's KE is (500) (2)2 = 2,000 joules

The difference is the energy i.e. the work you have to put into it

to raise the speed from 1 m/s to 2 m/s.

(2,000 - 500) = 1,500 joules there u go :D

lianna [129]

Answer:

95 intervals

Step-by-step explanation:

Given that

population mean = 100

standard deviation = 15

number of interval that involve the mean for 95% confidence interval is calculated as

We know that when we measure the 99 percent confidence interval, 99 outof 100 confidence interval are required to provide the mean population.

similarly

Assuming we measure a confidence interval of 95 percent, then we  should expect 95 out of 100 confidence interval to provide the mean population therefore, answer is 95

Solve the following two equations. Show all of your
Elena L [17]

Step-by-step explanation:

Given that,

Two equations,

3x + 11 = 11 .....(1)

And

3(x - 3) = 45

or

3x-9=45 ....(2)

Subtract 11 on both sides of equation (1).

3x + 11-11 = 11-11

3x=0

x = 0

Add 9 to both sides of equation (2)

3x-9+9=45+9

3x = 54

x = 18

Hence, the solution of equation (1) is x=0 and form equation (2) x = 18.
