Answer:Is an estimate of the average grams of salt used in 2012

Step-by-step explanation: Let

x ---> the number of years since 2012

f(x) ---> is the total amount of salt ingested in grams

we have

This is a linear equation in slope intercept form

where

The slope is equal to

The y-intercept or initial value is equal to

The y-intercept is the value of the function f(x) when the value of x is equal to zero

In this context, the y-intercept is the average amount of grams of salt ingested  in the year 2012

The exact value of the average amount of grams of salt ingested  in the year 2012 is 3,554 grams (see the data in the table)

Compare the exact value with the y-intercept

therefore

3,548 grams Is an estimate of the average grams of salt used in 2012

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

Exit A or exit B, so 2 desired outcomes.

This means that D = 2

Total outcomes:

Any of the 5 exits, so T = 5

Probability:

p = \frac{2}{5} = 0.4

Answer:

10 quarters

40 dimes

Step-by-step explanation:

q + d = 40

25q + 10d = 625

25 > 10

q < d

25(10) = 250

10(40) = 400

$2.50 + $4.00 = $6.00

Natali5045456 [20]

Answer:

D) 12,656

Step-by-step explanation:

First of all, as they have given us 3 quantities of plants in 1/2 an acre, we can work out the average amount of plants in 1 whole acre.

In the first 1/2 acre there were:

  • 291 plants

In the second 1/2 acre there were:

  • 327 plants

In the third 1/2 acre there were:

  • 286 plants

to work out the average, we add all these together then divide them by 3 (as there are 3 examples)

291 + 327 + 286 = 904

904 ÷ 3 = 301.3 (this is the average amount of plants in every 1/2 acre.) If we multiply this answer by 2 we will get the average amount of plants in every acre.

301.3 x 2 = 602.67 (average plants in every 1 acre) multiply by total acres (21) for your answer

602.67 x 21 = 12656 average plants in total

I hope this was helpful :-)

A store advertises 15% off an item that regularly sells for $300.
Ilia_Sergeevich [38]

Regular price = 300

Sale = 15%

Price after sale

= 300 - 15%(300)

= 300 - 15/100 x 300

= 300 - 15 x 3

= 300 - 45

= 255
