The correct option is C

Step-by-step explanation:

Generally

       [tex]MS_B[/tex] stand for Mean Square Between which the mean calculated based on the difference between the sample means

While

 [tex]MS_W[/tex] stands for Mean Square Within which the mean calculated based on the difference between the elements within the set(group)

   Thus  

The [tex]MS_B[/tex]  measures the differences related to the treatment given to each sample. The [tex]MS_W[/tex]  measures the differences related to entries within the same sample.

Ava is 23cm taller then Olivia, and Olivia is half the height of Lucas. If Lucas is 1.78m tall, how tall are Ava and Olivia

Answers

Answer:

Ava = 1.12 m tall

Olivia =  0.89 m tall

Step-by-step explanation:

given;

Ava is 23cm taller then Olivia,

Olivia is half the height of Lucas.

If Lucas is 1.78m tall

find:

how tall are Ava and Olivia

-------------------------------------

Ava = Olivia + 0.23

Olivia = Lucas / 2

Lucas = 1.78

plugin values into the equation above

Olivia = 1.78 / 2 =

Olivia =  0.89 m tall

Ava = 0.89 + 0.23

Ava = 1.12 m tall

In an alloy of gold and silver the ratio of the amount of gold to the amount of silver is 2:5.

What is the weight of gold in the alloy, if there are 80g of silver?

Answers

Given :

The ratio of the amount of gold to the amount of silver is 2:5.

To Find :

The weight of gold in the alloy, if there are 80 g of silver.

Solution :

Let, amount of gold is x.

So, the ratio of amount of gold and silver is :

[tex]\dfrac{x}{80}=\dfrac{2}{5}\\\\x=32\ g[/tex]

Therefore, the weight of gold in the alloy is 32 g.

Hence, this is the required solution.

Answer:

32

Step-by-step explanation:

do 80÷5=16 to get unit. Then do 16*2=32

what’s the slope-intercept form of y + 3 = 4(x - 5),

Answers

Slope-intercept form is: y = mx + b

m = slope

b = y-intercept

y + 3 = 4(x - 5)

Distribute the 4

y + 3 = 4x - 20

Subtract 3 from both sides.

y = 4x - 23

Answer:

Step-by-step explanation:

Slope intercept form...

y=mx+c

where, m=slope

c=intercept

y + 3 = 4(x - 5)

Open the Brackets.

y + 3 = 4x - 20

SUBTRACT 3 FROM BOTH SIDES.

y + 3 (-3)= 4x - 20 (-3)

Take note of the signs and solve.

y = 4x - 23

4 is the slope.

-23 is the intercept.

Find the extraneous solution of the equation |4x−42|=−10x.

Answers

Answer:

x=3 is the extraneous solution

Step-by-step explanation:

|4x-42| = -10x

Since it's absolute value and we know that there are two possibilities, we need two equations to set up to solve for x.

1st equation:

4x - 42 = -10x

2nd equation:

4x - 42 = 10x

Solve both equations for x:

1st equation:4x - 42 = -10x14x-42 = 014x=42x = 32nd equation:4x-42=10x-6x-42=0-6x=42x=-7

Plug in both values for x in the original equation to find the extraneous solution:

x=-7

|4x-42|=-10x|4(-7)-42|=-10(-7)|-28-42|=70|-70|=7070=70

x=3

|4x-42|=-10x|4(3)-42|=-10(3)|-30|=-3030≠-30

Solve the equation.
b + 6 = 27

Answers

Answer:

Step-by-step explanation:

b+6=27

b=27-6

b=21

Answer:

b = 21

Step-by-step explanation:

To find this answer, all you have to do is subtract 6 from both sides of the equal sign, where you will cancel out the 6 and subtract 6 from 27. 27 minus 6 is 21, so you are left with b = 21

Marc is creating a rectangular garden in his back yard. The length of the garden is 18 feet. The perimeter of the garden must be at least 60 feet and no more than 76 feet. Write and solve a compound inequality to find the range of values for the width, w, of the garden.

Answers

Answer:[12,20]

Step-by-step explanation:

The value of width will be from 12 to 20.

What is the perimeter of the rectangle?

The sum of all the sides of the rectangle will be known as the perimeter of the rectangle. Let L be the length and W be the width of the rectangle.

Then the perimeter of the rectangle will be

Perimeter of the rectangle = 2(L + W) units

Marc is creating a rectangular garden in his backyard. The length of the garden is 18 feet. The perimeter of the garden must be at least 60 feet and no more than 76 feet.

Then the inequality is given as,

60 < 2(W + 18) < 76

Simplify the inequality, then the value of the width W will be

60 < 2(W + 18) < 76

30 < (W + 18) < 38

12 < W < 20

Thus, the value of the width will be from 12 to 20.

to convert degrees Fahrenheit  to degrees Celsius. So replace the value for the Fahrenheit with 102 and solve for C:

[tex]C=\frac{5}{9} (F-32)\\C=\frac{5}{9} (102-32)\\C=\frac{5}{9} (70)\\C=\frac{350}{9} \approx38.89\,^oC[/tex]

1. In part (b) of the example, why isn't AB a correct answer? 2. In part (c) of the example, would KJL be an appropriate answer?

Answers

Answer:

Step-by-step explanation:

1. AB isn't a correct answer because it only refers to the part of the line between point A and point B. This is incorrect because it doesn't represent the whole line which goes on infinity past point A (as seen by the arrow).

2. KJL would not be an appropriate answer because the points must be listed in the same order that they appear in direction of the line. The angle shown is angle K so K should be the middle letter as it is the middle point with the angle. KJL would not be appropriate because it would refer to the angle J if there was another line between J and L.
