So, in 240 miles can be made by 2 hours.
Do this equation:
240 × 2 = 480 / 4 hours.
You cannot do 3 because it won't fit another 240 miles.
Next, subtract the 480 miles from 600 miles.
600 - 480 = 120
Also, if you would've divided by 2 hours.
240 ÷ 2 = 120 / 1 hour
Add the hours.
4 + 1 = 5 hours
It takes 5 hours to travel 600 miles by the small plane.
Answer:
No Solution
Step-by-step explanation:
For system of equations, you must equal the equations to each other like shown below:
Solve for x by subtracting 3x from both sides of the equation:
≠
Theorem: If a random variable is normally distributed with a mean of µ and a standard deviation of σ, then the sample mean with a sample size of n would be normally distributed too with the same mean and a standard deviation of
.
In this case, µ = 1200, σ = 60, sample size n = 36.
So the sample mean has a mean of 1200 and a standard deviation of
.
Then the z-score that corresponds to 1224 is
Answer:
r=4
Step-by-step explanation:
-4 (r+2) =4 (2-2r)
Divide each side by 4
-4/4 (r+2) =4/4 (2-2r)
-(r+2) = (2-2r)
Distribute
-r-2 = 2-2r
Add 2r to each side
-r+2r -2 = 2-2r+2r
r-2 =2
Add 2 to each side
r-2+2 =2+2
r=4
Check
-4 (r+2) =4 (2-2r)
-4 (4+2) =4(2-2*4)
-4(6) =4(2-8)
-24 = 4(-6)
-24 = -24
This checks
