Answer:

mean=28.8

median=31

Step-by-step explanation:

mean=sum of all values/number of all values

mean=40+45+7+21+31+40+45+7+21+31/10

  =288/10

mean=28.8

Median

arrrange in order

7,7,21,21,31,31,40,40,45,45  

in case of even ungrouped data median is the average of middle two values

  = (31+31)/2

     median =31

Answer:

30 degrees

Step-by-step explanation:

triangles have 180 degrees

right triangles have a right angle which is 90 degrees

180-90=90

90-60=30

Answer:

30 degrees

Step-by-step explanation:

A triangle has three sides that should add up to 180.

Since it is a right triangle a side has to be 90°.

90°+60°+_30°_ = 180°

Answer:

3/2 or 1.5 or 1 1/2

Step-by-step explanation

To divide, you must switch the -1/4 to its reciprocal which is -4/1 and then multiply the fractions (-3/8 * -4/1) and since negative - negative = positive. It's a positive.

Answer:

35/37

Step-by-step explanation:

hope this helps:)))

Step-by-step explanation:

The mean is the usual average, so add all of the numbers and then divide.

The mode is the number that is repeated more often than any other.

The range is the largest value and smallest value subtracted.

Answer:

Answer bellow

Step-by-step explanation:

To find mean(average) get all the numbers and and add them together after devide the added number by the number of numbers

To find mode rewrite all the numbers and look for numbers that are repeating (it can be more than one)

To find range take the biggest number from the data set and subtract it from the smallest number in the data set

Answer:

  B.  r = 6.30÷5

Step-by-step explanation:

The cost per pencil is found by dividing the cost by the number of pencils.

Here, the cost is $6.30 and the number of pencils is 5. Then the cost per pencil (r) is ...

  r = 6.30 ÷ 5

Answer:

sin x = 0.4706

Step-by-step explanation:

Given that,

Height, h = 8

Base, b = 15

Let H be the hypotenuse of the triangle. Using Pythagoras theorem,

[tex]H=\sqrt{8^2+15^2} \\\\H=17[/tex]

We know that,

[tex]\sin\theta=\dfrac{h}{H}[/tex]

So,

[tex]\sinx=\dfrac{8}{17}\\\\\sin x=0.4706[/tex]

So, the correct option is (b).

Answer:

probability = 0.07777

Step-by-step explanation:

there are 10 chips

white  1

red     4

green 2

blue   3

the probability of choosing the W chip is 1/10  or  0.10      

now there are 9 chips left (the first chip was not replaced)

the probability of choosing a non-green chip is (9-2)/9 =  7/9  = 0.7777  

so now I THINK you multiply the two probabilities to get the total probability

probability = 0.1 ·0.7777

probability = 0.07777    which makes sense it has to be less than 0.1

Answer:

7.07 in²

Step-by-step explanation:

Diameter = 3 in ( shown in figure )

Radius = 1/2( diameter) = 1/2 (3) = 1.5 in

Area of a circle = πr²

Area = (3.14)(1.5)²

Area = (3.14)(2.25)

Area = 7.065 in

Area = 7.07 in² ( round off)

Answer:

(4, 10) and (7, 7.5) are the solutions to this system.

You can see this by observing the two given points where the line and the parabola intercept.  Those are the only two points where that will happen.

Answer:

c = 9.2m is the answer.

Step-by-step explanation:

a = 6m

b = 7m

c = ?

According to the Pythagoras theorem,

a² + b² = c²

6² + 7² = c²

36 + 49 = c²

c² = 85

c = 9.2m

∴ the distance between the school and the candy store is 9.2m

Step-by-step explanation:

The solution to the proportion 2/4 = 5/x is x = 10.

To solve the given proportion 2/4 = 5/x, we can cross-multiply and then solve for x.

Cross-multiplying means multiplying the numerator of the first fraction with the denominator of the second fraction, and then multiplying the denominator of the first fraction with the numerator of the second fraction.

Using the given proportion:

2/4 = 5/x

Cross-multiplying:

2 * x = 4 * 5

Simplifying:

2x = 20

To isolate x, divide both sides of the equation by 2:

(2x)/2 = 20/2

Simplifying:

x = 10

Therefore, the solution to the proportion 2/4 = 5/x is x = 10.

Answer:

34,5 ?? I am not good at this but I did 92-23 that's 69 ÷ 2 = 34.5 ?

Answer:

Step-by-step explanation:

We can use the formula for the area of a triangle, to help us find the height:

Area=12⋅b⋅h

Using the formula for area, we can solve for the height by plugging in the information we have about the area and the base:

92=12⋅23⋅h

Isolate h by multiplying both sides by 2 and dividing both sides by 23.

hh=2⋅9223=8

The height is 8 inches.
