#16. Do the ordered pairs (-5,19), (-1,7),(3,-5),(6,-14), and (9,-23) represent a linear function? How do you know?

Using pemdas what is the answer to 6÷2(1+2) equal to?

jeka94

So pemdas
partneasees first ()

1+2=3
then dividsion multiplicatn wihciever comes first
6/2=3
3 times 3=9
answer is 9

Answer please! (No explanation needed!) <3

Hi there! Hopefully this helps!

Question A answer: 2.

To find the median, you simply need to order the set from lowest to highest and finding the exact middle. So it should look like this:

0, 1, 2, 3, 4. So 2 is the median, therefore 2 is the answer to Question A.

------------------------------------------------------------------------------------------------

Question B answer: 2

To find the mean, you have to add all of the numbers together and then you have to divide by the number of items in the set. There are 5 numbers in the set so it should look like this:

0 + 1 + 2 + 3 + 4 = 10.

Since there 5 numbers in the set, we need to divide by 5.

10 / 5 = 2.

Therefore, 2 is also the answer to Question B.

Edit: Whoops, sorry for the explanation...

1. Each month, the city of Accra generates an average of 28 pounds of waste. Assume the variable is approximately normally distr

Molodets [167]

1. Answer: given: an average of 28 pounds

a.

Find z values corresponding to 27 and 31:

z=%2827-28%29%2F2=-1%2F2=-0.5

z=%2831-28%29%2F2=3%2F2=1.5

Find the area between z+=+-0.5 and z=+1.5

Table E gives us an area of 0.9332-0.30=0.6247=> The probability is 62.47%

b.

Find z values corresponding to 30.2

z=%2830.2-28%29%2F2=2.2%2F2=1.1 Find the area to the right of z+=1.1

it gives you an area of 0.1357=> The probability is 13.57%

Mrs. Adesso wants to take her class on a trip to either the science center or natural history museum. The science center charges

BartSMP [9]

Answer:

25

Step-by-step explanation:

When we write expressions for the total cost of each field visit and set them equal, we find the solution to be the ratio of the difference in fixed cost to the difference in variable cost.

y = 75 +7x . . . . . cost for x students to visit the science center

y = 50 +8x . . . . cost for x students to visit the natural history museum

__

Subtracting the first equation from the second, we get ...

0 = -25 +x

25 = x . . . . . add 25; the number of students such that costs are equal

The cost will be the same either place for 25 students.

__

Additional comment

Here, the fixed cost difference is 75-50=25, and the variable cost difference is 8-7=1. The ratio of these costs is ...

$25/($1 /student) = 25 students.

This relationship only holds when the higher fixed cost is associated with the lower variable cost. Charges are such that one place caters to larger numbers of students (science center), and one prefers fewer students (natural history museum).

12.) Find the x-intercept and y intercept of the following equation. 9x + 6y = -36

Alik [6]

Answer:

Thevalue of x-intercept is 0

and y intercept is-6.

Step-by-step explanation:

here,9x+6y=-36

9x = -36 - 6y

x=(-36 -6y)/9

x=(-12-2y)/9.........(i)

putting value of x in question

9[(-12-2y)/9]+6y=-36

-12-2y+6y= -36

-12+4y= -36

4y=-24

y=-6

puting value of x in equation (i)

x=(-12-2y)/9

x=(-12-2×-6)/9

x=0
