Answer:

  A 2-column table has 3 rows. The first column is labeled x with entries 40, 160, 200. The second column is labeled y with entries 60, 15, 0.

Step-by-step explanation:

All of the tables have x=40 in the first column. The function value there is ...

  f(x) = (-3/8)(40) +75 = -15 +75 = 60

Only the last table has y = 60 for x = 40.

__

A check of the other points in that table shows they are all on the same (second) piece of the graph, as required by the problem statement. Those points are marked with a purple x in the attachment.

Answer:

<em><u>B. Store T sells apples at the lowest rate</u></em>

Step-by-step explanation:

Store R sells apples at $1.20 <u>per pound.</u>

Store S sells <u>4 pounds</u> of apples at $5.00.

Store T sells <u>3 pounds</u> of apples at $3.48.

To find the answer, <u>you have to find the unit price</u> for both Store S and Store T.

For Store S: 4 pounds = $5. <u>Divide the cost by the pounds</u>. This will give us <u>$1.25 per pound.</u>

For Store T: 3 pounds = $3.48. Same thing as Store S, d<u>ivide the cost by the number of pounds</u>. This will give us <u>1.16 per pound</u>.

Now, we know the unit prices for each store. It's time to answer the question.

A. Store R sells apples at the lowest rate.

This is <em><u>incorrect</u></em> because the store that sells the apples at the lowest rate is Store T.

B. Store T sells the apples at the lowest rate.

This answer is <em><u>correct</u></em>, but I'll also take a look at the other two

C. Store S charges a lower rate for apples than Store T.

Again, this is <em><u>incorrect</u></em> because Store T sells apples at the lowest rate.

D. Store T charges the same rate for apples as Store R.

<em><u>Nope</u></em>, Store T sells the apples at a lower rate than Store R.

This means your answer will be <u>B. Store T sells apples at the lowest rate</u>.

kodGreya [7K]
Mathematics is very important in a small business is because when you make money transactions with other people you need to know how to count money correctly and your calculations can’t be wrong. Mathematics is definitely helpful to me because Artificial Intelligence is taking on jobs, so we have to step up our game.

Line E'F' has endpoints located at E'(1,0) and F'(1,3). Line EF was dilated by a scale of 1/2 from the orgin. Which statement de
Lerok [7]

Answer:

If line EF was dilated by a scale of 1/2 from the origin to get line E'F', then if line E'F' is dilated by a scale of 2 from the origin, EF is obtained. Also, the length of EF is double than the length of E'F'.

Dilation by a scale of 2 from the origin transforms point (x,y) into (2*x, 2*y)

E'(1,0) -> E(2,0)

F'(1, 3) ->F(2, 6)

length of E'F': 3

length of EF: 6

A dieter believes that the average number of calories in a homemade peanut better cookie is more than the average number of calo
zalisa [80]

The confidence interval formula is computed by:

Xbar ± Z s/ sqrt (n)

Where:

Xbar is the mean

Z is the z value

S is the standard deviation

N is the number of samples

 

So our given are:

90% confidence interval with a z value of 1.645

Sample size 40, 45

Mean 180, 179

Standard deviation 2, 4

 

So plugging that information in the data will give us a confidence interval:

For 1:

Xbar ± Z s/ sqrt (n)

= 180 ± 1.645 (2 / sqrt (40))

= 180 ± 1.645 (0.316227766)

= 180 ± 0.520194675

= 179.48, 180.52

For 2:

Xbar ± Z s/ sqrt (n)

= 179 ± 1.645 (4 / sqrt (45))

<span>= 179 ± 1.645 (0.596284794)</span>

therefore, the answer is letter b
