Answer:

if you mean find the coordinates "of" the midpoint then the solution is

Step-by-step explanation:

(x1+x2)/2 and (y1+y2)/2

so

(2+6)/2=8/2=4 and (4+8)/2=12/2=6

so the coordinates of the midpoint of the given segment is

(4,6)

Answer:

  -27 -6z

Step-by-step explanation:

"Simplify" in this context means "eliminate parentheses." You do that by making use of the distributive property. The factor -3 outside the parentheses multiplies each term inside parentheses.

  -3(9 +2z)

  = -3(9) +(-3)(2z)

  = -27 -6z

Hey there!

-3(9 + 2z)

= -3(9) - 3(2z)

= -27 - 6z

= -6z - 27

Therefore, your answer is: -6z - 27

Good luck on your assignment & enjoy your day!

Answer:

a = 1

b = 5

⇒ f(x) = x + 5

Step-by-step explanation:

Given

Therefore,

f(1) = 6    ⇒   a + b = 6

f(-2) = 3   ⇒   -2a + b = 3

Rewrite a + b = 6 to make a the subject, substitute into  -2a + b = 3  and solve for b:

a = 6 - b

⇒ -2(6 - b) + b = 3

⇒ -12 + 2b + b = 3

⇒ -12 + 3b = 3

⇒  3b = 15

⇒  b = 5

Substitute found value for b into  a + b = 6  and solve for a:

⇒ a + 5 = 6

⇒ a = 1

Therefore, f(x) = x + 5

Answer:

A: Randomly select 10 freshmen from each of the majors at the university.

Step-by-step explanation:

This is because stratified random sampling is taking a population and dividing them into subpopulations. So, majors would be the best way to divide up college freshmen into different subsections to survey them about their workloads because each major would have a different answer and result.

The techniques to give a stratified random sample would be A: Randomly select 10 freshmen from each of the majors at the university.

If the sampling is done from the population randomly, without any other rule, then such sampling is called simple random sampling. Items are selected in a fixed size, all randomly.

The best sampling is simple random sampling, as it is randomly picking data values from the population.

Stratified random sampling it is taking a population and dividing them into subpopulations.

1 5/8 divided 1/3

first change 1 5/8 into a improper fraction which is 40/8

40/8 divided by 1/3
Keep Change Flip
40/8 divided by 3/1
40/8 x 3/1 = 120/8 simplify by 4 then you get 30/2 simplify again and you get 15/1 which is 15

Answer:

4 and 7/8 (or as a decimal: 4.875)

Step-by-step explanation:

(Important:) Okay, so before we solve this problem we need to know the "dividing fraction rules." When you are dividing fractions, you need to remember that the second fraction is flipped and the sign goes from being a division symbol to being a multiplication symbol. It may sound confusing, but I'll explain as we go on.

First, let's turn that 1 and 5/8 into an improper fraction so that this is easier to solve. Multiply the denominator by the whole number, then add the numerator. Keep the same denominator (8 in 1 and 5/8), but place your new numerator on top instead.

1 and 5/8 = 13/8.

Now we can go through the steps of the dividing process. Flip the second fraction in the equation. Doing this changes the symbol to a multiplication symbol.

13  x  3

8  x   1

Now multiply across.

13 x 3 = 39

8 x  1 =  8

This question does not ask for an improper fraction, so let's reduce this fraction down to a mixed number and decimal.

Mixed number: 39/8 = 4 and 7/8.

Decimal: 4.875.

I hope that this helps.

Answer:

angle xdq= 90-49= 41

angle uxd= 180-41= 139

Step-by-step explanation:

A right angle equals 90 degrees.

90-49 = angle xdq = 41 degrees

49 + 90 + x = 180

angle x = 41

180-41 = angl uxd = 139

Answer:

x = 6

y = 7

z = 23

Step-by-step explanation:

ÀC = z + 7

30 = z + 7

30 - 7 = z

z = 23

2x - 3 = 5x - 21

21 - 3 = 5x -2x

18 = 3x

x = 18÷3

x = 6

4x + 1 = 3y + 4

4(6) + 1 = 3y + 4

25 = 3y + 4

3y = 25 - 4

y = 21 ÷ 3

y = 7

First, let's find the area of the rectangle.We know that the area of a rectangle is the length times width, or  20⋅32in this example:20⋅32=640So the area of the rectangle is  640ft2.You may not know the area of a semicircle, but that's fine  −we know the area of a circle, or  πr2.Since the area of a semicircle is half the area of a circle, we just do the area of the circle divided by  2:So the area of a semicircle is  πr22.The question asks for  πto just be  3.14, so instead the equation is  A=3.14r22The picture gives the diameter of the circle.To find the radius, or  r, we divide the diameter by  2:202=10Now we can solve for the area of the semicircle:3.14(10)223.14(100)23142157ft2Now that we now the areas of the rectangle and semicircle, we can add them up to find the area of the rose garden:640+157=797ft2

We have that the population standard deviation and  confidence interval is mathematically given as

SD=1

W = 2.8284

a) Generally, normal distribution 95% of the values lies within 2 standard deviations from the mean.

Therefore, we have here:

2*2SD = 51 - 47

2*2SD

SD=1

Hence, the standard deviation is

SD=1

b)

Where,the margin of error is inversely proportional to the square root of sample size.

1 / sqrt{2}

Hence, the new width is

The scale factor from shape A to shape B is 0.75 with w = 5.25 cm.

The size by which the shape is enlarged or reduced is called as its scale factor.

Scale factor from shape A to shape B = [tex]\frac{3}{4}[/tex] = 0.75

It can be calculated by dividing the length of one side of the polygon to the corresponding side of the similar polygon. Keep the length of the side of the original figure in denominator and length of the side of the transformed figure in the numerator.

Answer:

(B) 18 cm x 8 cm

Step-by-step explanation:

let the length be x,

then the width is [tex]\frac{1}{3}[/tex]x + 2

2( [tex]\frac{1}{3}[/tex]x + 2 + x ) = 52

[tex]\frac{1}{3}[/tex]x + 2 + x  = 26

[tex]\frac{4}{3} x[/tex] = 24

x = (24*3)/4

x = 18

then the length is 18 cm

and width is (1/3)*18 + 2 = 8

Therefore the dimensions are length:width = 18 cm : 8 cm

Answer:

(B) 18cm x 8cm

Step-by-step explanation:

Perimeter of a rectangle  =  52 cm

2(length + width)  =  52 ==>  l + w  =  26

Let x be the length

width  =  (x/3) + 2

x + (x/3) + 2  =  26

[(3x + x)/3]  + 2 =  26

4x / 3  =  24

4x  =  24 (3)

x  =  6(3) ==>  18 cm

Width  =  (18/3) + 2

=  6 + 2  =  8 cm

So, the required dimension is 18 cm x 8 cm.
