15, 10, 19, 17, 16, 12, 20, 22, 18, 35
Planting soil 2 plant height:
16, 17, 10, 12, 18, 17, 14, 15, 17, 23
A) Planting soil 1 growth percentage is approximately 14% more than planting soil 2 growth percentage.

Answer 1

Answer:

Answer:

Step-by-step explanation:

First find the mean of each group. To do this we total the numbers and then divide by the number of measurements. There are 10 measurements for each.

Planting soil 1

15 + 10 + 19 + 17 + 16 + 12 + 20 + 22 + 18 + 35 = 184

184 / 10 = 18.4cm

18.4 / 5 cm = 368

368% growth

Planting soil 2

16 + 17 + 10 + 12 + 18 + 17 + 14 + 15 + 17 + 23 = 159

159 / 10 = 15.9

15.9 / 5 = 318

318% growth

The difference between the two plant percentage growths is 50%, with plant 1 being more than plant 2, so the answer is C.

. Is 10% of 10% of 100 the same as 20% of 100?

Answers

No. 20% of 100 is 20.

10% of 10% of 100 is 1.

the equations are:
.1 × .1 × 100 = 1

and

.2 × 100 = 20

So these are NOT the same

I’m guessing that the pool is about 8 meters deep.
7*4*8=224 cubic meters
224*.11= 24.64
So I would go with B

A right isosceles triangle has an angle with measure of 45*. If x represents the measure of the third angle of the triangle, what is x? PLEASE HELP ASAP

Answers

depends on which angle is x because the 2 smaller corner angles equals 45 degrees each which the third equals 90 degrees so it depends on which angle is x
