Answer:

x=26262626262626...

Step-by-step explanation:

Answer:

x(4 × 2) + x(3 × 4)

Step-by-step explanation:

The question says "which of the following equations" which infers you have already been given options. However, none were provided in the question so my answer may be slightly different than the given options as there's several ways to solve this problem.

Monday through Thursday = 4 days × 2 hours per day

Friday through Sunday = 3 days × 4 hours per day

To find the total for one week, add the two expressions together:

(4 × 2) + (3 × 4)

The question states for "x weeks" so:

x(4 × 2) + x(3 × 4)

This is one way the equation can be written

Another way is:

x[(4 × 2) + (3 × 4)]

If neither of these are answers for your mutliple choice question, then please provide the options and I will let you know which is correct

Answer:

Answer: 120

Step-by-step explanation:

Base x height / 2 (I think)

Answer:

180 Miles?

Step-by-step explanation:

First divide 150 by 2 1/2 (or 2.5)

You'll end up with 60

Then times it by the amount of hours (3)

60 x 3 = 180

Answer:

1. D and C

2. F = 9/5(k-273) + 32

Step-by-step explanation:

1. We simply want to write the given equation in different forms;

PV = nRT

So P = nRT/V

R = PV/nT

V = nRT/P

n = PV/RT

T = PV/nR

So the correct expressions are;

D, C,

2. we want to make F the subject of the formula, that would be;

C = 5/9(F - 32)

9C = 5(F - 32)

divide both sides by 5

9C/5 = F - 32

F = 9C/5 + 32

But K = C + 273

So C = K - 273

Insert this into the equation, we have

F = 9(K-273)/5 + 32

Answer:

The alternative is characterized in the interpretation section following the table, as per the case mentioned.

Step-by-step explanation:

According to the question:

The sample mean will be:

⇒ [tex]\bar{x}=\frac{\Sigma x}{n}[/tex]

      [tex]=\frac{1050500}{55}[/tex]

      [tex]=19100[/tex]

The critical value of z ([tex]z_e=1.96[/tex]) seems to be the 95 % confidence interval. So the required confidence interval will be:

=  [tex]\bar{x} \ \pm \ x_{critical}\frac{\sigma}{\sqrt{n} }[/tex]

= [tex]19100 \ \pm \ 1.96.\frac{3027}{\sqrt{25} }[/tex]

= [tex]19100 \ \pm \ 800[/tex]

The 95% confidence interval is ($18300 , $19900) and according to the confidence interval, the average estimated price of fires results through the use of tobacco is somewhat more costly than that of the average cost of flames results from across all factors that cause.

Given :

First, find the sample mean by using the following formula:

[tex]\rm \bar{x}=\dfrac{\sum x}{n}[/tex]

[tex]\rm \bar{x}=\dfrac{1050500}{55}[/tex]

[tex]\rm \bar {x} = 19100[/tex]

Now, for 95% confidence level, the confidence interval will be:

[tex]= \rm \bar{x} \pm x_{critical} \dfrac{\sigma}{\sqrt{n} }[/tex]

[tex]\rm = 19100\pm 1.96\times \dfrac{3027}{\sqrt{55} }[/tex]

[tex]=19100\pm 800[/tex]

The 95% confidence interval is ($18300 , $19900).

According to the confidence interval, the average estimated price of fires results through the use of tobacco is somewhat more costly than that of the average cost of flames results from across all factors that cause.

Answer:

34.5744 ≈ 35

Step-by-step explanation:

The formula for Margin of Error

= z × σ/√n

Where

z = z score of the confidence interval = z score of 95% = 1.96

σ = 15 pounds

n = number of samples = ??

Margin of Error = 5

Hence,

5 = 1.96 × 15/√n

Cross Multiply

5 × √n = 1.96 × 15

Divide both sides 5

√n = 1.96 × 15/5

√n = 1.96 × 3

√ n = 5.88

Square both sides

n = 5.88²

n= 34.5744

Approximately the size = 35

Answer:

Choice B

Step-by-step explanation:

The area of the triangle is 10 square units, the correct option is B.

A triangle is a polygon with three sides, angles, and vertices.

The triangle is classified into various types on the basis of the angle and on the basis of equality of the length of the sides.

The vertices of the triangle are at:

(-3,3), (2, 3), and (4,7).

The area of the triangle has to be determined.

The length of the sides will be calculated using the distance formula.

side 1 = [tex]\rm \sqrt { (3-3)^2 + ( 2 +3)^2}[/tex] = 5 units

side 2 = 2√5 units

side 3 = √65 units

The height of the triangle is determined by calculating the distance from (4, 7) to (4, 3).

The height of the triangle = 4 units

The area of a triangle is given by,

A = (1/2) * base * height

A = (1/2) * 5 * 4

A = 10 square units

Answer:

C) I got it right

Step-by-step explanation:

Answer:

Scale factor = [tex] \frac{5}{4} = 1\frac{1}{4} [/tex]

Step-by-step explanation:

The scale factor is how much the right triangle on the right was increased in size or enlarged, since the right triangle is a scaled copy of the one on the left.

The scale factor used = the ratio of any of their corresponding sides

Scale factor = side length of the ∆ on the right ÷ corresponding side length of the ∆ on the left

Scale factor = [tex] \frac{15}{12} [/tex]

Scale factor = [tex] \frac{5}{4} = 1\frac{1}{4} [/tex]

The scale factor expressed as a fraction is 4/5

Since the right triangle on the right is a scaled copy of the right triangle on the left, then the ratio of their similar sides is equal to the scale factor.

This is expressed as:

Taking the ratio of the fractions

[tex]\frac{20}{25} = \frac{4}{5}[/tex]

Similarly for [tex]\frac{12}{15}[/tex]

[tex]\frac{12}{15} =\frac{4}{5}[/tex]

This shows that [tex]\frac{20}{25} = \frac{12}{15} = \frac{4}{5}[/tex]

Hence the scale factor expressed as a fraction is 4/5
