Answer:

The rocket has a faster unit rate and is 219\ km/h much faster than the penny

Step-by-step explanation:

Find the unit rate of each object and the compare the results

step 1

Find the unit rate per hour of the rocket

To find the unit rate divide the total distance by the time

Let

d -----> the distance in km

t -----> the time in hours

we have

d=208\ km

t=50/60=5/6\ h

Find the unit rate

208/(5/6)=208*6/5=249.6\ km/h

step 2

Find the unit rate per hour of the penny

To find the unit rate divide the total distance by the time

Let

d -----> the distance in km

t -----> the time in hours

we have

d=153\ km

t=5\ h

Find the unit rate

153/5=30.6\ km/h

step 3

Compare the unit rates

The units rate of rocket is 249.6\ km/h

The unit rate of penny is 30.6\ km/h

Find the difference

249.6-30.6=219\ km/h

therefore

The rocket has a faster unit rate and is 219\ km/h much faster than the penny

You must first normalize this in order to use a Z-score table. To convert what you have into a Z score you must use this formula: (x- mean) /standard deviation. In your case (334-310)/12=2. So now you want the probability that a score is greater than 334, which in turn means you want P(Z>2)=1-P(Z<2)=1-.9772=0.0228=2.28%.

Which function is the inverse of f(x)=9x-3
DIA [1.3K]
F^-1(x)= x/9 + 1/3

To find this, just interchange the variables and solve for y.

y=9x-3
x=9y-3
x+3=9y
divide by nine
