Step-by-step explanation:

(27 + 39 + S)/3 = 36

27 + 39 + S = 36(3)

27 + 39 + S = 108

Step-by-step explanation:

Answer: x= 33

i subtracted -10 away from 56  and i got 66, then i divide 66 by 2x and got 33x.. which is your answer ;)  

The denominator is the bottom number.

To change the 5 to 10, you would multiply 5 by 2: 5 x 2 = 10

Because you multiplied the 5 by 2, you also need to multiply the numerator ( top number) by the same amount.

1 x 2 = 2

So 1/5 = 2/10

The answer is 2/10

Step-by-step explanation:

quiz scores:

a. arrange them all from least to greatest to figure out the median first

your quiz: 15, 16, 17, 18, 19     middle # = 17        median = 17

friend's quiz: 12, 13, 17, 20, 20     middle # = 17       median = 17

now for mean add all of your quiz scores up and divide by how many #s

15 + 16 + 17 + 18 + 19 = 85 / 5 = 17          mean = 17

now your friend's:

12 + 13 + 17 + 20 + 20 = 82 / 5 = 16.4       mean = 16.4

mode is which number is used the most

your mode = you don't have a mode       your friend's mode = 20

b. you have a higher mean than your friend

world populations:

a. range is to subtract the smallest number from the largest

803 - 31 = 772

b. mean is adding it all up and dividing by how many numbers there are:

803 + 487 + 348 + 368 + 730 + 31 = 2767 / 6 = 461.17

median is arranging them in order and finding the middle #

31, 348, 368, 487, 730, 803

368 + 487 = 855 / 2 = 427.5

mean = 461.17

median = 427.5

mode = no mode

tomato plants:

a. range is subtracting the smallest from the largest

52 - 36 = 16

b. mean is adding all the #s and dividing by how many #s there are:

36 + 45 + 52 + 40 + 38 +41 + 50 + 48 = 350 / 8 = 43.75

median is the middle from least to greatest

36, 38, 40, 41, 45, 48, 50, 52

41 + 45 = 86 / 2 = 43

mean = 43.75

median = 43

mode = no mode

Answer:

The perimeter of the room is 60 feet.

Step-by-step explanation:

If the area of the room is 224 square feet, and one side is 14 feet, then the other side is 224/14 feet, or 16 feet.

This gives us the dimensions of the room, 14 x 16.

From this, we can calculate the perimeter, which would be 2(14+16), or 60.

Answer:

55

Step-by-step explanation:

Number of Jone's goats = 550

Let Number of King's goat = x

Jone's goat is 10% more than King's ;

Thus, number King's goat would be ;

x = 550 - (10% of 550)

x = 550 - 55

x = 495

x = Mr. King's goat

Hence, Jones goat is :

550 - 495 = 55 more than Mr King's goat.

Mr King has 55 goats

Number of goats owned by Mr Jones is 550

let y represent the goats owned by Mr King

y= 550-(10% × 550)

= 550- (0.1×550)

= 550 - 55

= 495

= 550-495

= 55

Hence Mr King has 55 goats than Mr Jones

Answer:

35.36

Step-by-step explanation:

For Class A

Class A has 11 pupils

The mean score for Class A is 32.

The total score of the students =

Mean score × Number of pupils

= 32 × 11

= 352

For Class B

Class B has 14 pupils. The mean score for class B is 38.

The total score of the students =

Mean score × Number of pupils

= 38 × 14

= 532

Total number of pupils for both classes = (11 + 14)pupils

= 25 pupils

Total score for both class = 532 + 352

= 884

The mean score(rounded to 2DP) in the maths test across both classes is calculated as:

Total score of both classes÷ Total number of pupils

884 ÷ 25

Answer:

 ( 2x +4) ( x+6)

Step-by-step explanation:

Explanation:-

Given expression   2 x² + 16 x + 24

The factors of 48 =  12 × 4

⇒   2 x² + 16 x + 24

⇒    2 x² + 12 x + 4x + 24

⇒   2 x ( x +6 ) + 4( x +6)

(-∞,-16)U(16/9,5)

Answer:

n = 3,4,5

Step-by-step explanation:

3n + 4 < 19

3n ≤ 15

n ≤ 5

10n/n+16 > 1

10n > n²+16

-n²+10n-16

(-n+2)(n-8)

n = 2 or n = 8

2 < n < 8

So 2<n≤5 = 3,4,5

Calculate the amount of people on both sides.

32% preferred cats

32% of 800

0.32 × 800 = 256 people

27% preferred dogs

27% of 800

0.27 × 800 = 216 people

So 256 people preferred cats and 216 people preferred dogs.

256 - 216 = 40 people

40 more people preferred cats than preferred dogs

40 people preferred cats more than preferred dog.

Percentage is a measurement to find value of given number out of hundred.

Given that,

Total number of people participated in survey = 800.

Percentage of people who preferred cats = 32%,

And percentage of people who preferred dogs = 27%.

The percentage of  people who preferred cats more than preferred dogs

= 32 - 27

= 5 %

The number of people preferred cats more than preferred dogs

= 800 x 5/100

= 40.

There are 40 more people preferred cats than dog.
