Answer:

A) A unit rate relates a quantity to 1 : TRUE

B) unit rates can be used to compare two rates : TRUE

C) any rate is equivalent to its unit rate

. FALSE

D) a unit rate always relates quantities with the same units. FALSE

Step-by-step explanation:

The ratio that which is used to compare quantities of different kinds is known as the rate of that quantity.

A unit rate is the ratio.

Number of units of the first type of quantity : Number of units of the second type of quantity.

Now,

A) a unit rate relates a quantity to 1.

TRUE, as a UNIT is equivalent to one.

Hence, unit rate unit rate relates a quantity to 1.

B) unit rates can be used to compare two rates

TRUE, unit rate compares two rates.

C) any rate is equivalent to its unit rate

FALSE, only the rate of one single unit is equivalent to its Unit Rate.

D) a unit rate always relates quantities with the same units

FALSE, rate compares the two terms which are in different units.

The water works commission needs to know the mean household usage of water by the residents of a small town in gallons per day.

Answer:

A sample of 179 is needed.

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1 - 0.85}{2} = 0.075$

Now, we have to find z in the Ztable as such z has a pvalue of $1 - \alpha$ .

That is z with a pvalue of $1 - 0.075 = 0.925$ , so Z = 1.44.

Now, find the margin of error M as such

$M = z\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

A previous study found that for an average family the variance is 1.69 gallon?

This means that $\sigma = \sqrt{1.69} = 1.3$

If they are using a 85% level of confidence, how large of a sample is required to estimate the mean usage of water?

A sample of n is needed, and n is found for M = 0.14. So

$M = z\frac{\sigma}{\sqrt{n}}$

$0.14 = 1.44\frac{1.3}{\sqrt{n}}$

$0.14\sqrt{n} = 1.44*1.3$

$\sqrt{n} = \frac{1.44*1.3}{0.14}$

$(\sqrt{n})^2 = (\frac{1.44*1.3}{0.14})^2$

$n = 178.8$

Rounding up

A sample of 179 is needed.

Which statement about an input/output table is true?

GREYUIT [131]

The answer is c because the input values do not have to be consecutive, the output values can be decimals and fractions, and the output values are not always increasing as they go on, sometimes they decrease. for example, look at exponential decay and exponential growth. hope this helped (;

You need a right triangle correct. If you used a graph and put the points (5,12) & (11,12) it would make sense to have the next point --this(11,4)
