Answers

Answer:

r = -12

General Formulas and Concepts:

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define

6 + 18r = 20r - 18 - 4r

Step 2: Solve for r

Combine like terms:                    18r + 6 = 16r - 18Subtract 16r on both sides:         2r + 6 = -18Isolate r term:                               2r = -24Isolate r:                                        r = -12
6+18r=20r-18-4r
6+18r=18r-18
-6. -6
18r=18r-24
-18r. -18r

Start by using your first factor, 1. Substitute "1" for each "x" in the equation: (1)3 - 4(1)2 - 7(1) + 10 = 0.

This gives you: 1 - 4 - 7 + 10 = 0.

Because 0 = 0 is a true statement, you know that x = 1 is a solution.

For the equation y = 2.5X, choose which ordered pairs would be on the line if it was graphed? Select ALL that apply.

(0, 0) and (-4, -10)

(-1, -2.5)

(0. 0) and (2, 5)

(3, 7.5) and (-3, -7.5)

(1, 3.5) and (2, 5)

(1, 2.5) and (3, 6.5)

Answers

Answer:

(0, 0) and (-4, -10)

(0. 0) and (2, 5)

(3, 7.5) and (-3, -7.5)

Step-by-step explanation:

We have the function:

y = 2.5*x

This is a linear relationship, with a slope equal to 2.5 and y-intercept equal to zero.

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

Then we can check with the points given in the options, and see which ones meet these two criteria.

a) (0, 0) and (-4, -10)

the slope will be:

a = (-10 - 0)/(-4 - 0) = 2.5

The slope is 2.5, then:

y = 2.5*x + b

To find the value of b, we just need to replace the values of one of the points in the equation, let's use the point (0, 0)

0 = 2.5*0 + b

0 = 0 + b

Then b = 0

y = 2.5*x

This means that these points would be on the line when graphed.

b) (0. 0) and (2, 5)

in this case the slope is:

a = (5 - 0)/(2 - 0) = 2.5

then:

y = 2.5*x + b

to find the value of b, let's use the point (0, 0)

0 = 2.5*0 + b

0 = 0 + b

b = 0

then

y = 2.5*x

This ordered pair would be on the line when graphed.

c) (3, 7.5) and (-3, -7.5)

The slope is:

a = (-7.5 - 7.5)/(-3 - 3) = 2.5

y = 2.5*x + b

The value of b will be obtained by using the point (3, 7.5)

7.5 = 2.5*3 + b

7.5 = 7.5 + b

b = 0

Then:

y = 2.5*x

This ordered pair will be on the line when graphed.

d) (1, 3.5) and (2, 5)

The slope is:

a = (5 - 3.5)/(2 - 1) = 1.5

The slope is different than 2.5, then we can discard this pair.

e) (1, 2.5) and (3, 6.5)

the slope is:

a = (6.5 - 2.5)/(3 - 1) = 2

Again, the slope is different than 2.5, then this option can be discarded.

We can conclude that the ordered pairs that will be graphed are:

(0, 0) and (-4, -10)

(0. 0) and (2, 5)

(3, 7.5) and (-3, -7.5)

Suppose Metro by T-Mobile wants to offer a simple extended warranty plan. If your phone is damaged, they will repair it for up to $50. If you lose or destroy your phone, they will give you a $200 voucher towards a new phone. The company believes that 5% of customers will need the replacement voucher and 10% will request a repair. What is the standard deviation?

Answers

Answer:

45

Step-by-step explanation:

Given that :

Voucher awarded (x) :

Repair = $50

Lose or destroy = $200

P(x):

Replacement voucher = 5%

Repair voucher = 10%

X ______ 50 ______ 200

P(x) ____ 0.1 _______ 0.05

Expected variance Var(X) :

ΣX²p(x) - E(x) ;

E(x) = Σx*p(x) = (50*0.1) + (200*0.05) = 15

ΣX²p(x) = Σ[(50^2 * 0. 1) + (200^2 * 0.05)] = 250 + 2000 = 2250

Var(X) = 2250 - 15^2 = 2025

Standard deviation = √Var(x)

Standard deviation = √2025

Standard deviation = $45
