The fit line equation is Y = -2.61x +152.51, where x is variable 1 and Y is variable 2. According to the equation, what is the expected value of Y when x-value is 45?

Answers

The expected value of y when x is equals to 45 in the equation is 35.06

How to find variable from an equation?

The equation is given as follows;

y = -2.61x + 152.51

where

x = variable 1y = variable 2

Therefore,

when

x = 45

y = -2.61x + 152.51

y = -2.61(45) + 152.51

y = - 117.45 + 152.51

Answer:

187 Points

Step-by-step explanation:

Total ratio units = 17 + 14 = 31 units

Total they scored = 341 points

Therefore total units = 31 = 341 points

31 units = 341 points

1 unit = (341/31) points

1 unit = 11 points

Nina scored 17 units of the total points

Step-by-step explanation:

The line where it says 2cm, extend that line to the top. You know have 2 triangles, call the one on the left A and the one on the right B

area of recntangle = bh

Rect A:

b = 5

h = 4 - 2

h = 2

bh = 5 x 2

bh = 10

Rect B:

h = 4

bh = 4 X 3

Answers

The measures of GX = 13

The measures of [tex]\angle ABX=22^0[/tex]

EX = 4z + 1  and XF = 2z + 7

Take EX and XF equal time each other and then solve for z and then you will get GX because EX = XF = GX are congruent.

EX = XF

What is congruent?

Two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.

4z + 1 = 2z + 7

2z = 6

z = 3

As,    EX = XF = GX

EX = 4(3) + 1

EX = 13

Therefore, GX = 13      ------      ( EX = XF = GX )

To find the angle ABX, divide the angle ABC by 2 you will get

Sun-roof, and Keyless entry
2. Write an inequality to model purchasing a car from Dealership A with the desired add-on options and staying within your budget. Use x to represent the base price of the car. (Assume that only the base price of the car is taxed to simplify the problem.)
3. Solve for x. Explain in words what the solution to the inequality means.
4. Graph the possible base price values that are included in the solution. Please upload an image of your graph.
5. Complete 2–4 for Dealership B using the same add-on options.
Will you buy from Dealership A or from Dealership B? Why?

Answers

The best buy is from dealership B because dealership B has a lesser base price

The add-on options

For the purpose of this exercise, the add-on options to select are:

SunroofKeyless entry

Dealership A

The total amount of the add-on options is:

Total = $500 + $1500

Total = $2000

The inequality

This is represented using:

Base price * (1 + Tax) + Fees + Add-on total ≤ 20000

So, we have:

(1 + 6.75%) * x + 751.56 + 2000 ≤ 20000

Solve for x

We have:

(1 + 6.75%) * x + 751.56 + 2000 ≤ 20000

Evaluate the like terms

(1 + 6.75%) * x  ≤ 17248.44

Divide both sides by (1 + 6.75%)

x  ≤ 16157.79

The solution means that the base price of the car cannot exceed $16157.78 for dealership A

The graph of the possible base price

See attachment

Dealership B

The total amount of the add-on options is:

Total = $750 + $1000

Total = $1750

The inequality

This is represented using:

Base price * (1 + Tax) + Fees + Add-on total ≤ 20000

So, we have:

(1 + 6.75%) * x + 1524.72 + 1750 ≤ 20000

Solve for x

We have:

(1 + 6.75%) * x + 1524.72 + 1750 ≤ 20000

Evaluate the like terms

(1 + 6.75%) * x  ≤ 16725.28

Divide both sides by (1 + 6.75%)

x  ≤ 15667.71

The solution means that the base price of the car cannot exceed $15667.71 for dealership B

Answers

The value of the relative frequency distribution of the first interval, having a frequency of 14, and the total frequency given is 40, is 0.35.

In a Relative Frequency Distribution, we list how often a data value appears and scale it using the total frequency.

The sum of Relative Frequencies adds to 1.

In the question, we are informed that the first interval has a frequency of 14.

This implies that the data appears 14 times in the first interval.

Also, we are told that the total frequency is 40.

Thus, the relative frequency can be calculated as the ratio of the frequency of the interval to the total frequency.

Therefore, Relative frequency = 14/40 = 0.35.

Thus, the value of the relative frequency distribution of the first interval, having a frequency of 14, and the total frequency given is 40, is 0.35.
