Estimate the sum.

10 1/9 + 5 14/15

Answer:

If you are looking for the slope, it equals -6

Step-by-step explanation:

(3,4) (5, -8)

[tex]\frac{4+8}{3-5}[/tex] = [tex]\frac{12}{-2}[/tex] = [tex]\frac{6}{-1}[/tex] = -6

Hey there!

The formula to this equation is: y2 - y1 /x2 - x1

• y2 = -8

• y1 = 4

• x2 = 5

• x1 = 3

EQUATION:

-8 - 4/5 - 3

-8 - 4 = -12

5 - 3 = 2

NEW EQUATION: -12/2

-12/2 = your answer

-12 / 2 = -6 because 2 • -6 = -12

Answer that you’re looking for: -6

Good luck on your assignment and enjoy your day!

1 apple: 24 people

2 apples: 12 people

3 apples: 8 people

4 apples: 6 people

6 apples: 4 people

8 apples: 3 people

12 apples: 2 people

24 apples: 1 person

Step-by-step explanation:

The number of 6 people can have 4 apples each.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

Priya is sharing 24 apples equally with some friends.

She uses division to determine how many people can have a share if each person gets a particular number of apples.

For example, 24 ÷ 4 = 6 means that if each person gets 4 apples,

then 6 people can have apples,

= 24 ÷ 6

= 4

Therefore, 6 people can have 4 apples.

Answer:

Dimension: 2inches by 4 inches

Step-by-step explanation:

Given

[tex]Width = 2wice\ Length[/tex]

Required

Determine the dimension.

This is calculated as :

[tex]Area = Length * Width[/tex]

[tex]A = L * W[/tex]

So:

[tex]A=L * 2L[/tex]

[tex]A=2L^2[/tex]

Substitute 72 for A

[tex]72=2L^2[/tex]

Divide bith sodes by 2

[tex]36 = L^2[/tex]

Take square root of both sides

[tex]L = 6[/tex]

Recall that:

[tex]Width = 2 * Length[/tex]

Hence:

[tex]LEnhth= 0 * 2[/tex]

[tex]LEnhth= 2[/tex]

Hence, the dimension is: 2 by 3 inches

The volume of the metal used to make the pipe is [tex]\mathbf{1,680\pi\ cm^3}[/tex]

Step-by-step explanation:

The Volume of a Cylinder

Given a right cylinder of base radius r and height h, the volume is calculated as follows:

[tex]V=\pi r^2h[/tex]

We are given the dimensions of a cylindrical metallic pipe whose external diameter is de=12 cm and the internal diameter is di=8 cm. The height is h=21 cm.

The volume of the metal used in making the pipe is the difference between the external volume and the internal volume.

Calculating the external volume:

[tex]V_e=\pi r_e^2h[/tex]

[tex]V_e=\pi 12^2*21[/tex]

[tex]V_e=3,024\pi\ cm^3[/tex]

Calculating the internal volume:

[tex]V_i=\pi r_i^2h[/tex]

[tex]V_i=\pi 8^2*21[/tex]

[tex]V_i=1,344\pi\ cm^3[/tex]

The volume of metal is:

[tex]V_m=V_e-V_i=3,024\pi\ cm^3-1,344\pi\ cm^3[/tex]

[tex]V_m=1,680\pi\ cm^3[/tex]

The volume of the metal used to make the pipe is [tex]\mathbf{1,680\pi\ cm^3}[/tex]

I guess you're asking to compute the difference,

-3224₅ - 3434₅

Ignore the minus signs for now, and consider the sum

3224₅ + 3434₅

In the 5⁰ place (the rightmost digit) we have

4₅ + 4₅ = 8 = 13₅

Carry the 1 to the next place. In the 5¹ place,

2₅ + 3₅ + 1₅ = 6 = 11₅

Carry the 1. In the 5² place,

2₅ + 4₅ + 1₅ = 7 = 12₅

Carry the 1. In the 5³ place,

3₅ + 3₅ + 1₅ = 7 = 12₅

So,

3224₅ + 3434₅ = 12213₅

and hence

-3224₅ - 3434₅ = -12213₅

Answer:

The emergency medical technician made $739.12 per week

Step-by-step explanation:

Given that:

Per hour pay = $19.71

One month earning of emergency medical technician = $3326.06

Weeks in the following month = 4.5

For per week income, we will divide the monthly salary by number of weeks in the month.

Per week income = [tex]\frac{3326.06}{4.5}[/tex]

Per week income = $739.12

Hence,

The emergency medical technician made $739.12 per week

Step-by-step explanation:

Steps down below. Remember that angles on a straight line add up to 180 degrees

Answer:

7 metre

Step-by-step explanation:

Let the breadth of the room is x.m. , then the length is (x+2).m. , accordingly:-

(x+2).x. = 63.

or, x^2 +2 x - 63 = 0.

or, (x + 9).(x -7) =0.

or, x = - 9 (not valid) , 7 .

Thus , the length = (x+2).m.= (7+2) = 9.m. , breadth = x .m. = 7.m. , Answer.

Finding the error for each observation, squaring the error and minimizing the sum

Step-by-step explanation:

The regression line is a straight line which gives a description of how the dependent variable y changes as changes occur in the independent variable X. It gives a prediction of the value of Y for any given value of X.

The method of least squares is used for squaring the error and also used for minimising the sum. Therefore, when you calculate the regression line, you would be Finding the error for each observation, squaring the error and minimizing the sum.

Step-by-step explanation:

Please find the complete question in the attached file.

Using formula:

[tex]\text{Margin of error} = \frac{(z \times \sigma) }{\sqrt{n}}[/tex]

n = the number of work cycles for 95 confidence interval

z-score = 1.96

So, [tex]\frac{(z \times \sigma)}{\sqrt{n}}[/tex] = [tex]\ Mean \times 0.02[/tex]  

[tex]\frac{(1.96 \times 0.376)}{\sqrt{n}} = 4.416666667 \times 0.02 \\\\\\[AVERAGE(4,4.5,5,4.5,4.5,4) = 4.416666667][/tex]

[tex]\sqrt{n} = \frac{(1.96 \times 0.376)}{(4.416666667 \times 0.02)} \\\\[/tex]

     [tex]= 8.342943396\\\\[/tex]

[tex]n = 69.6047045[/tex]

   [tex]= 70[/tex]

Using the sample size formula, the number of samples required is 919.

From the data given :

Using the sample size relation thus:

Substituting the values into the equation :

[tex] n = (\frac{4.032 \times 0.376 }{0.05})^{2}[/tex]

[tex] n = (\frac{1.516032}{0.05})^{2} = 919.34[/tex]
