Answer:

Mean = 33.7

Median = 34.5

Mode = 34

Range = 33

After adding 26....

mean decreases by 0.7

median decreases by 0.5

mode is 34

range is 33

Step-by-step explanation:

mean = sum of all the data values/number of data values

= (18 + 19 + 20  + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7

To find median arrange the values in increasing order, find the mid value

If the number of data points is even, find the average of the mid 2 data values

Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51

Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5

The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once

Mode = 34

The range is highest - lowest = 51 - 18 = 33

After we add 26, we get the following data set arranged

18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51

we can calculate the stats using the same technique as above

We get the following values

mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33  

median = 34

mode = 34

range = 51-18 = 33

To find the decrease in mean and median subtract from the first set of values

Answer:

A. x = -6
B. x = 15

Step-by-step explanation:

A.

\(\frac{x}{3}-5=-7\\\frac{x}{3}-\frac{15}{3}=-7\\\frac{x-15}{3}=-7\\x-15 = -7*3\\x-15=-21\\x=-21+15\\x=-6\)

B.

\(\frac{x}{2}-5=2.5\\\frac{x}{2}-\frac{10}{2} = 2.5\\\frac{x-10}{2}=2.5\\x-10= 2.5*2\\x-10=5\\x=5+10\\x=15\\\)

Answer:

A, C

Step-by-step explanation:

If it is inversely proportional then y = k/x

Let's try one by one for the options. (im replacing y and x in the equation and finding k to see if k is the same all throughout)

A.

6 = k/1 (k=6)

3 = k/2 (k=6)

2 = k/3 (k=6)

1.5 = k/4 (k=6)

Yes! It's the same everywhere so this is correct!

B.

7.5 = k/2 (k=15)

5 = k/3 (k=15)

3 = k/5 (k=15)

2 = k/7 (k=14)

For the last one k is not the same so nope. It is wrong.

C.

24 = k/1 (k=24)

8 = k/3 (k=24)

k = 6×4 = 24

k = 24×1 = 24

This is correct too.

D.

k = 0.1×200 = 20

k = 0.3×40 = 12

k = 0.8 × 25 = 20

We can already see that k is not the same everywhere.

Only A and C, x and y are inversely proportional for all of the values

Answer:

The total area of the back classroom wall is (20ft x 12ft) = 240ft²

The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².

Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.

Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

Answer:

incorrect, correct answer is 4√2

Step-by-step explanation:

When you remove the square root You will have to remove them completely. so that the inside of the square root cannot be removed any more numbers (I'm not good at English but I hope u understand what I want u to know :)))

√32 = √2×2×2×2×2

Match 2 identical numbers one at a time and bring them out. ;

√32 = 2×2√2

√32 = 4√2 correct answer!

find you If you want to check if your square root removal is correct or not. Multiply the answer you have given by itself, for example:

4√2 × 4√2 = 16×√4 = 16×2 = 32 correct!

hope it helps you <3

She had taken 2 outside without consideration of square root. And the correct value of √32 is 4√2.

If the value of a numerical expression is terminating then they are the rational number then they are called the rational number and if the value of a numerical expression is non-terminating then they are called an irrational number.

Jaclyn estimates the square root of 32 in the following way:

√32 = 2√16 = 2 ∗ 4 = 8

a)  She had taken 2 outside without consideration of square root.

b)  The √32 is correctly solved below.

\(\sqrt{32} = \sqrt{2*2*2*2*2} = 2*2*\sqrt2=4\sqrt2\)

Then the correct value of √32 is 4√2.

Step-by-step explanation:

\(\frac{1}{w^{6} }\) i hope this helps!!

Answer:

The simplified expression is 1/w^6.

Step-by-step explanation:

Using the product of powers exponent rule, we have

w^3 * w^(-9) = w^(3 + (-9)) = w^(-6).

However, the problem says to write the expression using only positive exponents. Here's an example of how to interpret negative exponents as positive exponents:

3^2 = 9

3^1 = 3

3^0 = 1

3^(-1) = 1/3

(and keeps on dividing by three onward)

Here, we see that 3^(-1) = 1/3^1.

Applying the same logic here, we have

w^(-6) = 1/w^6.

Step-by-step explanation:Quadrant I and Quadrant IV

Two out of the four Quadrant planes have a positive x- value.

The coordinate axis split the plane into four parts called Quadrants or which can also be called Cartesian quadrants. These divided parts of the plane are numbered I, II, III, and IV.

The first quadrant/ quadrant I which lies on the upper axis on the right side of the plane has two positive quadrants, that is one positive x and one positive y because both of them lie in the positive direction of the axis.

The second quadrant/ quadrant II which appears on the upper right side of the plane has one positive and one negative coordinate that is, one positive y and one negative x because the x coordinate lie in the opposite direction of the sign of the numbers.

In quadrant III which lies in the downward direction and the left side of the plane has two negative coordinates both x and y. both the coordinates go towards the opposite direction of the sign convention.

in the last quadrant/ quadrant IV have a positive x- coordinate and one negative y-coordinate. Because the y coordinate goes against the positive sign convention.

Answer:

1.6 liters of lemonade

Step-by-step explanation:

There are 1000 milliliters in one liter so she made 8000 milliliters of lemonade

Next we have to figure out how many milliliters of lemonade she sold each day:

Saturday: 200 milliliters of lemonade in a glass * 8 glasses = 1600 milliliters of lemonade sold

Sunday:  200 milliliters of lemonade in a glass * 24 glasses = 4800 milliliters of lemonade sold

1600  + 4800 = 6400 total milliliters of lemonade sold

Since there are 1000 milliliters in one liter, we have to divide 6400 by 1000:

6400 ÷ 1000 = 6.4 liters

Lastly, we have to subtract 6.4 from 8:

8 - 6.4 = 1.6 liters of lemonade
