z scores are useful because they:a. allow us to convert raw scores to mean scores, compare scores from different samples, and transform populations into samples.b. transform linear scores into nonlinear scores, convert nonlinear scores back into linear scores, and allow us to obtain comparisons between nonlinear and linear scores.c. give us an understanding of where a score falls in relation to the mean of its underlying population, allow comparisons to be made between scores from different distributions, and permit the transformation of z scores into percentiles.d. reduce the probability of Type I and Type II errors, allow us to compare raw scores with standard scores, and permit the transformation of raw scores into percentiles.

Answer:

x = -1

y = -5

Step-by-step explanation:

y = x - 4                                     y = x - 4

2x + 3y = -17                             y = (-1) - 4

2x + 3(x - 4) = -17                      y = -1 - 4

2x + 3x - 12 = -17                       y = -5

5x - 12 = -17

5x - 12 + 12 = -17 + 12                 Check

5x = -5                                    2x + 3y = -17

5x/5 = -5/5                           2(-1) + 3(-5) = -17

x = -1                                        -2 + -15 = -17

                                                   -17 = -17

Step-by-step explanation:

Independent variables may be referred to as one or more single or standalone variables which affects the outcome or output variable, which is the dependent or response variable. To determine the cost of sandwich (this will be the response variable), this will be affected or dictated by the independent variables, which includes ; the size of sandwich, the type of bread roll used (hard roll, soft bun, hero, slice bread). Also, the tyoe of sandwich filling which may be (cheese, Ham salad, Ham and cheese, Egg mayonnaise and so on). Therefore, these variables are independent and the combination of each of these predictor variables will dictate the dependent variable, Cost.

Answer:

4 movies, $20

Step-by-step explanation:

Given data

Family Video

charges $10 for a monthly membership and

$2.50 per movie

let the number of movies be x

and the charge for x movies be y

y= 10+2.5x----------1

Babe's  Movies

charges a $12

membership and $2 per

movie.

let the number of movies be x

and the charge for x movies be y

y= 12+2x----------2

equate 1 and 2

10+2.5x= 12+2x

collect like terms

12-10= 2.5x-2x

2= 0.5x

x= 2/0.5

x= 4 movies

put x= 4 in equation 1 or 2

y= 12+2x----------2

y= 12+2*4

y= 12+8

y= $20

Answer:

y < 28

Step-by-step explanation:

get the y on its own

y/2 - 6 < 8

y/2 - 6 + 6 = y/2

8 + 6 = 14

y/2 < 14

y/2 x 2 = y

14 x 2 = 28

y < 28

Answer:

36

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

72° and 3x are adjacent angles and are supplementary , that is

72° + 3x = 180° ( subtract 72° from both sides )

3x = 108° ( divide both sides by 3 )

x = 36° → C

Answer:

y=15

Step-by-step explanation:

Since the triangles are similar you take 22/33 and 10/y then cross multiply and get 330=22y now divide 330 by 22 and you get 15

The value of x is 26.4 unit and y is 15 units,

Two triangles are said to be comparable if their two sides are in the same ratio as the two sides of another triangle and their two sides' angles inscribed in both triangles are equal.

Given:

As, the two triangles are similar then the ratio of their corresponding sides and angles are equal.

So, 22/ 10 = 33/ y

22y = 330

y = 330/22

y = 15

and, 22/10 = x/ 12

264 = 10 x

x= 26.4

Hence, the value of x is 26.4 unit and y is 15 units,

Given:

A recipe uses 4 pounds of rice and 5 quarts of boiling water.

To find:

The rate of rice to quarts of water for this recipe.

Solution:

We need to divide the amount of rice by amount of water to get the rate of rice to quarts of water for this recipe.

[tex]\text{Required rate}=\dfrac{\text{Rice in pounds}}{\text{Water in quarts}}[/tex]

[tex]\text{Required rate}=\dfrac{4}{5}[/tex]

[tex]\text{Required rate}=0.8[/tex]

Therefore, the  rate of rice to quarts of water for this recipe is 0.8.

Answer/Step-by-step explanation:

An expression is a series of number without any signs so expression would be the first one.

Inequality would be when they do a sign like > or <, etc. so it would be the 2nd one.

Equation would be when they have an equal sign which would be the 3rd one.

Simple Ex.

Expression : 2 + 66 / 11 - 3 x 2

Inequality : g + h > f

Expression : 4j - 3 = j
