Answer:

24

Step-by-step explanation:

3*8 = 24

Answer:

68%

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean of 75, standard deviation of 4.

What percent had scores between 67 and 75?

67 = 71 - 4

75 = 71 + 4

Within 1 standard deviation of the mean, so, by the Empirical Rule, 68%.

Hello!

This is strange. It seems to give you the answer.

I am assuming your teacher would just like you to identify what a radius is.

All the same, I'll let you know the equation for finding a radius.

r= d × 2 (D is equal to diameter, and r to radius)

If you were given the diameter,, you would simply multiply it by 2 to get your radius.

The correct answer to your question is:

7 inches.

Answer:

33 1/3%

Step-by-step explanation:

(672 - 600) / 4 = 72 / 4 = $18, which is 33 1/3%

Hope that helps! A Brainliest would be appreciated :)

Answer:

3%

Step-by-step explanation:

1) 672-600=72 = the simple interest

2) 72=600(4)r which equals 72=2400r

3) divide 72 by 2400 which get 0.03

4) 0.03 = 3%

Answer:

36 m²

Step-by-step explanation:

A = 1/2h × (sum of bases)

A = 1/2(4)(6 + 12)

A = 2·(18)

A = 36 sq m

Answer:

12.5 sq. units

Step-by-step explanation:

Divide the blue triangle into two smaller triangles.

The length of their common base = 5 units

The height of the yellow triangle = 2 units

The height of the red triangle = 3 units

The area of the yellow triangle

= (5×2)÷2

= 5 sq. units

The area of the red triangle

= (5×3)÷2

= 7.5 sq. units

The total area

= 5+7.5

= 12.5 sq. units

Answer:

1.

mean= 84.6

median=84

mode=84

2.

mean=10.14

median=9

mode=9

3.

mean=22.3

median=21

mode=phi

Step-by-step explanation:

mean: the sum of of the quantities by their number

median: the median value after rearranging the values

mode: the value that occurs most frequently

in the second question

mean = (8+9+9+9+9+10+11+15)/8

median(even number) =(9+9)/2=9

mode=9

Answer:

for data set 1

1.mean-84.6

2.median-(84+84)/2 = 84

3.mode-84

for data set 2

1.mean-9.25

2.median-(9+9)/2 = 9

3.mode-9

for data set 3

1.mean-22.3

2.median-21

3.mode-no mode with this data set

Monday, Wednesday, Tuesday and Thursday is the order from least to greatest.

A fraction represents a part of a whole.

Monday = [tex]3\frac{1}{3}[/tex]

Convert mixed fraction to improper 10/3

Decimal value 3.33

Tuesday = [tex]3\frac{2}{5}[/tex]

The improper fraction is 17/5

Decimal value 3.4

Wednesday = [tex]3\frac{3}{8}[/tex]

The improper fraction is 27/8

Decimal 3.375

Thursday = [tex]3\frac{1}{2}[/tex]

The improper fraction is 7/2 which is 3.5

Answer:

Measure of E'F' = 9

Step-by-step explanation:

If a quadrilateral is dilated by a scale factor of [tex]\frac{3}{4}[/tex], all the sides of preimage CDEF will be dilated with the same factor to form image quadrilateral C'D'E'F'.

Scale factor = [tex]\frac{\text{Dimension of image}}{\text{Dimension of preimage}}[/tex]

[tex]\frac{3}{4}=\frac{E'F'}{EF}[/tex]

[tex]\frac{3}{4}=\frac{E'F'}{12}[/tex]

E'F' = [tex]\frac{3}{4}\times 12[/tex]

      = 9

Therefore, measure of side E'F' will be 9.

Mina is analyzing products of negative numbers. Is the product (- 7.291015)(- 3.214195) • (- 2.124819) positive or negative? How do you know ? Explain your reasoning . If 99 negative numbers are multiplied together , is the product positive or negative ? How do you know ? Explain your reasoning

Answer:

Probably the easiest way to visualise negative and positive numbers is using a number line, a tool with which you may well be familiar, especially if you have children at primary school.

It looks something like this:

Number line showing a scale of -25 to +25.

A number line can help you to visualise both positive and negative numbers and the operations (adding and subtracting) that you can do with them.

When you have an addition or subtraction to calculate, you start at the first number and move the second number of places either to the right (for an addition) or left (for a subtraction).

This number line is a simplified version, but you can draw them with every number included if you wish. The big advantage of a number line is that it is very easy to draw for yourself on the back of an envelope or a piece of scrap paper, and it is also quite hard to go wrong with the calculation. As long as you are careful to count the number of places that you are moving, you will reach the correct answer.

[tex]4 + 9 = 9 + x \\ 4 + 9 - 9 = x \\ 4 = x[/tex]

=> ᵗʰᵉ ᵐⁱˢˢⁱⁿᵍ ᵛᵃˡᵘᵉ ⁱˢ 4.

The missing Value is 4.

According to the commutative property, the numbers on which we operate can be swapped out or moved without affecting the result. Subtraction and division are not supported by the property, but addition and multiplication are.

Given Expression

4 + 9 = 9 + ?

According to Commutative  property

A + B = B + A

for expression

4 + 9 = 9 + 4

or let missing number be x

4 + 9 = 9 + x

x = 4 + 9 - 9

x = 4

Hence the missing value is 4.
