In Class 1, what is the median score? A) 70 B) 70.5 C) 71.5 D) 72

Answers

Answer:

B)  70.5

Step-by-step explanation:

Median = middle value when the values are placed in order.

If there are two middle values, the median is the mean of those two values.

Class 1

45 46 51 52 53 53 61 63 64 65 66 68 70 70 71 73 76 77 79 81 82 83 84 87 90 92 93 95

There are 28 values in Class 1.

Therefore, there are two middle values: 14th and 15th values

14th value = 70

15th value = 71

[tex]\implies \textsf{Median}=\dfrac{70+71}{2}=70.5[/tex]

Answer:

70.5

Step-by-step explanation:

What value added to the set below would give a mean of 33?

{19, 27, 64, 36}
19

30

27

42

Answers

Answer is 19

If you add all of the numbers together including 19. You would get 165, then divide the total by 5. Your answer would be 33!

Answer:

19

Step-by-step explanation:

Given:

data = [19,27,64,36]mean value = 33

To find:

another data / last data

Therefore:

New data is 19,27,64,36,xWhere x is an unknown value/data.

Mean Value:

[tex]\displaystyle \large{m=\dfrac{1}{n}\sum_{i =1}^n x_i \to \dfrac{x_1+x_2+x_3+...+x_n}{n}}[/tex]

m = mean valuex1+x2+x3+...+xn = sum of all datan = amount of data

Therefore:

[tex]\displaystyle \large{33=\dfrac{19+27+64+36+x}{5}}[/tex]

Solve for x - first, multiply both sides by 5 to clear out the denominator:

[tex]\displaystyle \large{33\cdot 5=\dfrac{19+27+64+36+x}{5} \cdot 5}\\\displaystyle \large{165=19+27+64+36+x}[/tex]

Evaluate the sum:

[tex]\displaystyle \large{165=146+x}[/tex]

Subtract both sides by 146:

[tex]\displaystyle \large{165-146=146-146+x}\\\displaystyle \large{19=x}[/tex]

Therefore, another value/data that will give a mean value of 33 is 19.

5. Laura uses 3 yards of fabric to make 2 skirts. She uses the same amount of fabric to make each skirt. At this rate, what is the total amount of fabric, in yards, she needs to make 6 skirts?

Answers

Answer:

1. 9/24 = 0.375 ounces

You have 9 ounces of clay that make up 24 pieces therefore you need to divide the 9 by 24 to work out how much clay is used for one piece

2. X=7

To solve the equation you want x to be on its own. To do this you need to minus the 5 from the left. But what you do to one side you must do to the other so x=7 because 12-5=7

3. 3y-1

To get three times yvonnes age you need to multiple y by 3 making it 3y. You then need to take off one year which quite simply makes the expression 3y-1

4. 18/3= 6mm

You divide the total depth by the number of hours to get 6mm.

5. 3x3=9 yards

6 skirts is three times as many skirts as 2 skirts (6/2=3) and because Laura uses 3 yards for every 2 skirts you multiple 3 by 3 to get the 9 yards

During a clearance sale, Archer bought a DVD-player which was regularly priced $320 at a discount of 25%. In addition, he had to pay 5% tax. If Archer had to put 10% of what he had to pay including tax as down payment, how much money did he have to pay for the down payment?

Answers

Answer:

The answer is : 25.20

Step-by-step explanation:

The selling price of the player: 320×(100%-25%) = 240

The total payment with tax: 240×(100%+5%) = 252

The down payment: 252×10% = 25.20

We know 20%=$15 and the percentage goes up 20% each time so you keep adding $15 on. For question 2 the bar is half way between 0 and 20 and half of 20 is 10.
