Answer:

A. x < 6 and x > - 28

Step-by-step explanation:

We have been given the following inequality;

| x+11 | < 17

We can replace the absolute value function by re-writing the inequality as;

-17< x+11<17

subtract 11 from both sides;

-17-11<x+11-11<17-11

-28<x<6

splitting this we have;

x<6

x>-28

Answer:

A. x < 6 and x > - 28

Step-by-step explanation:

| x+11 |< 17

x + 11 < 17

x < 6

-(x + 11) < 17

-x - 11 < 17

-x < 28

x > - 28

Answer

6 > x > -28 (x < 6 and x > - 28)

When would you want to use the median over the mean for describing the measure of center for a data set?

zheka24 [161]

Hello!

Sometimes when there are outliers in a data set, for example 1, 20,25,26,30, one is the outlier and when you find the mean it will not represent the data in the most accurate way. This is when you use the median to represent the part of the data set that has the information that is close together.

I hope this helps!

Makayla and Caroline go to the movie theater and purchase refreshments for their friends. Makayla spends a total of $49.00 on 9

gizmo_the_mogwai [7]

Answer:

Let the cost of each popcorn bag be x and cost of each drink be y

Cost of 9 bags of Popcorn= 9 x

Cost of 8 drinks be = 8 y

Total money spent by Makayla = $ 49

According to Question

9 x + 8 y= 49..................... equation (1)

Similarly , cost of 3 popcorn = 3 x

Cost of 3 drinks= 3 y

Total money spent by Caroline= $ 17.25

According to Question

3 x+ 3 y= $ 17.25...................equation(2)

We can solve above equation by using elimination method

Multiply equation (2) by 3

9 x + 9 y = 51.75..................equation(3)

9 x + 8 y= 49..................... equation (1)

Subtraction equation (1 ) from equation(3)

y = 2.75

put value of y in any equation (2)

we get

3 x + 3 × 2.75 = 17.25

3 x + 8.25 = 17.25

3 x = 17.25 - 8.25

3 x = 9

x = 3

Hence, cost of each popcorn bag $ 3 cost of each popcorn bag is also $ 3 (approx)

Murphy loves pistachio nuts. Every Saturday morning, she walks to the market and buy some. Last week, she bought two pounds and

BARSIC [14]

Answer:

3.98

Step-by-step explanation:

From the above question,

Cost is directly proportional to the Number of pounds

Hence:

C ∝ N

= C = kN

Where k = Proportionality constant

We are told:

Last week, she bought two pounds and paid $7.96,

Hence:

7.96 = 2k

k = 7.96/2

k = 3.98

This week she bought only one half pound and paid $1.99,

1.99 = k × 1/2

k = 1.99/ 1/2

k = 3.98

Hence, the constant rate of proportionality is 3.98

which set of numbers can represent the side lengths, in centimeters, of a right triangle?a. 8,12,15b. 10,24,26c. 12,20,25d. 15,1

Mama L [17]

Answer:

Step-by-step explanation:

Pythagorean theorem (applicable on right triangles only) says:

$a^{2}+b^{2}=c^{2}$

Where $a$ and $b$ are the two legs of the triangle and $c$ is the length of the hypotenuse [THE LONGEST SIDE].

<u>We can square each leg on the triangle and take the sum, if that is equal to the square of the longest side, we have a right triangle. Let's check for all of these.</u>

$8^{2}+12^{2}\\=64+144\\=208$
