Derrick needs to figure out how he’s doing on his test scores so far this year. You can help by calculating the mean and the median to get an overall picture of his scores. Below are all of his scores:

25, 40, 68, 85, 95, 98, 70, 78, 85, 100

Answers

Answer 1

Answer:

Mean = 74.4

Median = 81.5

Step-by-step explanation:

25, 40, 68, 85, 95, 98, 70, 78, 85, 100

Mean = Sum of values / Number of values

Number of values = 10

= 25 + 40 + 68 + 70 + 78 + 85 + 85 + 95 + 98 + 100/10

= 744/10

= 74.4

Median

Rearranging the given data

= 25, 40 ,68 ,70 ,78 ,85 ,85 , 95 ,98 ,100

Formula for median = 1/2(n + 1)th value

n = 10

Hence

1/2(10 + 1)th value

1/2(11)th value

= 5.5 th value

This fall between the 5th and 6th value

5th value = 78

6th value = 85

Hence: 78 + 85/2

= 163 / 2

= 81.5

Of the clients who had their hair cut at Tanner's salon last month, 4 clients had black hair and
12 clients had hair in other colors. Considering this data, how many of the next 12 clients to
get haircuts should you expect to have black hair?

Answers

Answer: 3

Step-by-step explanation:

The number of getting the black hair color clients will be 4.

What is probability?

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favorable outcomes / Number of samples

Given the of the clients who had their hair cut at Tanner's salon last month, 4 clients had black hair and 12 clients had hair in other colors.

The probability is:-

P = 4 / 12

The number of clients having black color hair is calculated as:-

Number = ( 4 / 12 ) x 12

Number =  4

Therefore, there will be 4 people getting black hair colors.

Answers

Answer:

28/53

Step-by-step explanation:

We need the cos of Q

therefore we'll use CAH (in SOH, CAH, TOA)

where CAH means

cos(angle)=adj/hyp

the side that adjacent to Q is 28

and the hypotonous (the oppsoite to the right angle) is 53

therefore cos(q)=28/53

Find 100% of 188:
Find 50% of 188:
Find 25% of 188:
Il
Find 75% of 188: 14

Answers

Answer:

100% = 188

50% = 94

25% = 47

add 50% value and 25% value 141 or you can multiply 188 by .75

Step-by-step explanation:

hat is pretty simple first think 188 is the 100 percent

the 50 percentage is dividing by 2 the number or multiplying by 0.50 that is 50% so it's 94

to get 25 porcent you can't multiply by .25 or divide by 4

to get 75 porcent add the values of 50 and 25 percent or multiply 188 by .75

If m <1 = 115° and the m < 8 = 105°, what is the measure of angle 5?

Answers

Answer:

measure of angle 5 = 75 degrees

Step-by-step explanation:

given measure of angle 8 = 105 degrees,

angle 8 and angle 5 are in a linear pair so,

(the sum of angles in a linear pair is 180 degrees)

therefore, angle 8 + angle 5 = 180 degrees

therefore,. 105 + angle 5 = 180 degrees

angle 5 = 180 - 105

angle 5 = 75 degrees

Four of the interior angles of a hexagon measure 92°, 100°, 94°, and 140°. The remaining two angles each measure (x−32)°. What is the value of x? Justify your response.

A. The sum of all interior angle measure is 540°
, so each angle measuring (x−32)° has a measure of 123°
. Thus, (x−32)°=123°, and so x=155.

B. The sum of all interior angle measure is 720°
, so each angle measuring (x−32)° has a measure of 294°. Thus, (x−32)°=294°, and so x=326.

C. The sum of all interior angle measure is 720°
, so each angle measuring (x−32)° has a measure of 147°
. Thus, (x−32)°=147°, and so x=179.

D. The sum of all interior angle measure is 540°
, so each angle measuring (x−32)° has a measure of 246°. Thus, (x−32)°=246°, and so x=275.

Answers

Answer:

The answer is x=294 (B)

Step-by-step explanation:

Remember, all interior angles of a hexagon add to 720.

So add all the  given numbers first.

92+100+94+140+x= 720

426+x=720

-426 from both sides

x= 294

3.) In triangle RST, RS = 4, ST = 5, and RT = 6. Which angle is largest?
Hint draw a picture!
A) B) C) D) Cannot be determined

Answers

Answer:

So If you start with sinØ = .5

your calculator is programmed to always give the closest angle to 0, and that would be 30°

You probably used the cosine law to find the first angle. A suggestion is to always find the largest angle first. If that happens to be an obtuse angle, your calculator will find the correct angle.

Of course there can only be one obtuse angle in a triangle, so using the sine law for your second angle does not result in any problems

notice that in your solution 78 and 102 add up to 180 , and sin 78 = sin(180-78) = sin 102

I would have found angle S first, the largest angle always opposite the largest side.

7^2 = 5^2 + 4^2 - 2(5)(4)cosØ

40cosØ = -8

cosØ = -8/40 = -1/5

Ø = 101.537°

Now you can use the sine law and you will find the correct other angles.

Answers

Answer:

C: 23 centimeters

Step-by-step explanation:
