Answer: Noah is right. If the mean for the second lake is 60ft and the first lake is 45ft, the second lake has an average depth that is 15 feet deeper.
The standard deviations also indicate that the second lake has some even deeper spots, and even the shallower spots of the second lake are about the same as the shallow spots of the first lake.
Step-by-step explanation:
I think it would be y=(-9/5)x -1/9
Answer: y= -1x-2
Step-by-step explanation:
the line crosses at -2 on the y axis and travels negatively up 1 over 1
Answer:
b
Step-by-step explanation:
the volume (V) of a cone is calculated as
V =
πr²h ( r is the radius , h is the height )
here diameter = 12 , so r = 12 ÷ 2 = 6 and h = 22 , then
V =
π × 6² × 22
=
π × 36 × 22
=
π × 792 ( cancel 3 and 792 by 3 )
= π × 264
≈ 829.4 m³ ( to the nearest tenth )
'is' means equals
'of' means mutily so
we have
18 =0.4 times what
divide both sides by 0.4
45=what
the answer is the number is 45
