Answer:

The value is a statistic because the 6,076 adults in public restrooms are a sample

Step-by-step explanation:

A measure that is calculated from a sample is known as sample statistic.

A study conducted and for the study 6076 adults are selected to inquire about the hand washing habit of adults. The selected 6076 adults are a sample and for this sample we computed the average 23% which demonstrates that 23% of adults did not wash their hands before exiting. So, a statistic is 23% and  6076 adults are a sample.

spin [16.1K]

Answer:

\frac{-75ft}{30sec} or simplified would be \frac{-2.5ft}{sec}

Step-by-step explanation:

In order to calculate the rate of change, we must subtract his end position and end time by the starting position and starting time. We are using the -15 feet since it is below the surface area as the starting position and the 10 seconds as the starting time. We make each of these into a fraction and subtract like so...

\frac{-90ft - (-15ft)}{40sec - 10sec} = rate of change

\frac{-75ft}{30sec} = rate of change

\frac{-2.5ft}{sec} = rate of change

Therefore, we can see that the rate of change of the diver is \frac{-75ft}{30sec} or simplified would be \frac{-2.5ft}{sec}

Arturo invests $2700 in a savings account that pay 9% interest, compounded quarterly. If there are no other transactions, when w
Sedbober [7]
The correct formula for this is as follows:
A=P(1+\frac{r}{n})^{nt}
where n is the number of compounding periods per year, and r is the annual interest rate as a decimal,
Plugging the given values into the formula, we get:
4550=2700(1+\frac{0.09}{4})^{4t}
This equation can be simplified to:
1.6852=(1.0225)^{4t}
Taking logs of both sides gives:
log 1.6852=4t\times log 1.0225
which can be rearranged to get:
t=\frac{log 1.6852}{4\times log 1.0225}=5.864
So it will take about 5.864 years for the amount to reach $4550.

how do i make the answer appear in pi form. i did 1/6 pi multiply by 1/12 pi and the answer was 0.1370778389 i want it in pi how
andreev551 [17]

Step-by-step explanation:

what you did was you multiplied all numbers (incl. pi as number) :

1/6, pi, 1/12, pi

and that gives 0.137077839. no i or pi attached. just the plain result number.

so, if you need to just calculate the factors of pi, but don't need the fully numeric result, then your problem looks like

1/6 × pi × 1/12 × pi = 1/72 × pi²

so, you have an expression of pi² with a factor of 1/72.

you only need to type in all the factors, not pi itself (that's what you need to add at the end yourself).
