Answer:
net amount $885.98 tax at 8.5% is $75.31 gross amount is $961.29
Answer:
8.3
Step-by-step explanation:
The tenths spot in 8.275 is where the 2 is. Since it is a 75 after that you will round it up.
. Tenths (2), Hundredths (7), Thousandths (5)
Answer:
A.) the number of photos Nina needs to sell to make profit
Step-by-step explanation:
you can tell this because she has to sell X number of photos and times that number by 2 and then take away 14 so her final number to make profit or even make back her money is that X number
Answer:
The true mean
it probably could be larger, smaller, or equal to 22
Step-by-step explanation:
False.
By definition the sample mean is defined as:

For this case the value for the sample size is n =190 and the calculated sample mean is
. This value represent the sample and for this case we can't assume that this value represent at all the population as the population mean
since we probably have variability from the data of the students at City College.
So we can conclude that the true mean
it probably could be larger, smaller, or equal to 22
To solve this we are going to use the kinematic equation for final velocity:

where

is the final velocity

is the initial velocity

is the acceleration

is the time
We know for our problem that the the velocity at the beginning of the slope is

, so

. We also know that the speed ad the bottom of the slope is

, so

. We also know that the acceleration is

, so

. Lets replace those values in our formula and solve for

:





seconds
We can conclude that it takes the roller coaster
3 seconds to reach the bottom of the slope.
