The root of the equation z + 4 = -8 is

Answer:

Its d

Step-by-step explanation:A probability of 1 indicates an event will definitely happen.

The true statement  is D; probability of 1 indicates an event will definitely happen.

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

P(E) = Number of favorable outcomes / total number of outcomes

Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence . An event's probability is a number between 0 and 1, where approximately 0 indicates how unlikely the event is to occur and 1 indicates certainty.

It is a numerical representation of the likelihood or likelihood that a particular event will occur, Alternative ways to express probabilities are as percentages from 0% to 100% or from 0 to 1.

The correct statement is D; A probability of 1 indicates an event will definitely happen.

Step-by-step explanation:

The question is incomplete. However, I will solve using the following assumptions.

Job A:

[tex]y = 2x + 5[/tex]

Job B

[tex]\begin{array}{cccccc}x & {1} & {2} & {3} & {4} & {5} \ \\ y & {6} & {10} & {14} & {18} & {22} \ \end{array}[/tex]

The first step is to calculate the rate of Job B using:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where:

[tex](x_1,y_1) = (1,6)[/tex]

[tex](x_2,y_2) = (2,10)[/tex]

So, we have:

[tex]m = \frac{10 - 6}{2 - 1}[/tex]

[tex]m = \frac{4}{1}[/tex]

[tex]m = 4[/tex]

So, the hourly rate of job B is $4/hr

For Job A:

[tex]y = 2x + 5[/tex]

A linear equation has the form:

[tex]y = mx + b[/tex]

Where m is the rate

By comparison:

[tex]m = 2[/tex]

So, the hourly rate of Job A is $2/hr

Comparing both rates, we can draw the following conclusions;

Step-by-step explanation:

probability (P) is calculated as

P = [tex]\frac{favourableoutcome}{numberofpossibleoutcomes}[/tex]

Here favourable outcome is a purple brick

number of possible outcomes = 6 + 5 + 4 = 15

P(purple brick ) = [tex]\frac{6}{15}[/tex] = [tex]\frac{2}{5}[/tex]

Answer:

[tex]x=0.61485921[/tex]

Step-by-step explanation:

The given equation is in exponential form:

[tex]6^{4x} =82[/tex]

To find [tex]x[/tex] we need to write it in logarithmic form:

[tex]b^{a} =n[/tex] ⇒ [tex]log_{b} n=a[/tex]

[tex]6^{4x} =82[/tex] ⇒ [tex]log_{ 6 } 82=4x[/tex]

           [tex]2.45943684 = 4x[/tex]

              [tex]\frac{2.45943684}{4} = x[/tex]

           [tex]0.61485921 =x[/tex]

To prove this, we can substitute the value into the given equation

             [tex]6^{4x} =82[/tex]

[tex]6^{4(0.61485921)} =82[/tex]

               [tex]82=82[/tex]

Therefore, the answer is [tex]x=0.61485921[/tex]

Answer:

$20.30

Step-by-step explanation:

Original price = 100% of the price

100% = $29

1% = 29 ÷ 100 = 0.29

Sale percentage = 30%

30% = 0.29 x 30 = 8.70

Since they are asking for the sale price of the shoes, it means the price of the shoes after the discount of the sale percentage.

29 - 8.70 = 20.3

Volume of the prism:

Scaled volume is 60 - 70 in³

Find the scale factor k;

So the scale factor is

and the volume of the smaller prism is:

Answer:

Scale factor 1/19, volume 65.6 in³

Step-by-step explanation:

Volume of the prism:

V = abh

V = 300*50*30 = 450000 in³

Scaled volume is 60 - 70 in³

Find the scale factor k;

450000/60 = 7500

450000/70 = 6428

1/6428 < 1/k³ < 1/7500

1/∛6428 < 1/∛k³ < 1/∛7500

1/18.59 < 1/k < 1/19.57

1/k = 19 is best

So the scale factor is

k = 1/19

and the volume of the smaller prism is:

450000 / 19³ = 65.6 in³
