Answer: C

Step-by-step explanation:

x = 2 $\sqrt{y+2}$ - 6

x + 6 = 2 $\sqrt{y+2}$

((x+6)/2 = $\sqrt{y+2}$ )^2

(x+6/2)^2 = y+2

y = (x+6/2)^2 -2

y= 1/4x^2 +3x +7

6, 3, 4, 7, 3, 7, 8, 5, 7 i. Find the median ii. Find the mean iii. Find the modal mark

4vir4ik [10]

Answer:

i. 6

ii. $5\frac{5}{9}$

iii. 7

Step-by-step explanation:

First organize the data from least to greatest. 3,3,4,5,6,7,7,7,8

To find the median, remove the extremes from the data over and over.

3,4,5,6,7,7,7

4,5,6,7,7

5,6,7

To find the mean, add all of the numbers and divide by 9

3+3+4+5+6+7+7+7+8=50

50/9= $5\frac{5}{9}$

To find the modal mark, simply find the number present most in the data set: 7(occurs 3 times)

Matching quantities with units

Mrrafil [7]

Answer:

1. Volume = length x width x height => cubic centimetres.

2. Perimeter = 2(length) + 2(width) => metres.

3. Speed = Distance /time => metres per second.

4. Area = length x width => square metres.

Step-by-step explanation:

1. Volume = length x width x height

If the length, width and height are measured in centimetre (cm) , then, the unit of the volume will be:

Volume = cm x cm xcm = cm3 i.e cubic centimetres.

2. Perimeter = 2(length) + 2(width)

If the length and width are measured in meter (m), then, the unit of the perimeter will also be in metre (m).

3. Speed = Distance /time

If the unit of distance is measured in metre (m) and the time is measured in second (s), then , the unit of the speed will be:

Speed = Distance /time = m/s i.e metres per second.

4. Area = length x width

If the length and width are measured in metres (m), then, the unit of the area will be:

Area = m x m = m2 i.e square metres
