Hello!
We know that the length of the pack is 8 cm, width is 2 cm, and the volume is 48 cm^3.
The formula for volume is:
V = l × w × h
We don't want to find the volume...we already have that!
But we can use the volume and the length and width to find the height.
Since we multiply the dimensions to find the volume, we'll have to do the opposite to find a dimension.
And what's the opposite of multiplication? Division!
H = V ÷ lw
Multiply the length by the width, then divide the volume by that.
H = 48 ÷ 8(2)
H = 48 ÷ 16
H = 3
We can double check by using this to find the volume.
V = 8 × 2 × 3
V = 48
This means we're right!
ANSWER:
The height of the pack of gum is 3 centimetres.
Answer: 36
Step-by-step explanation:
36 ÷ 6 = 6
Answer:
There is a difference in mean hand span between male and female if you notice the difference between their averages. 2cm is quite significant
female mean = 19.6 cm and male mean = 21.6 cm
Step-by-step explanation:
a.) There is a significant difference.
take P( Z < ( 19.6 - 21.6) / 1) = P(Z < -2) = 2% probability of assuming that male and female means are the same. too low to think like that.
b.) Differ by 2cm. MAD= Mean Absolute Deviation , MAD within their own data set seem similar
C.) The variability in hand spans among male and female are very similar, since they both have the same MAD = 1.0
