The temp. rose by 17 degrees and then fell by 17 degrees. This means that the net change in temp over the course of the day was zero.
Given mean μ = 7.6 and standard deviation σ =3.1
The z score value for x= 5 is given by
Z = 
Z = 
Z = -0.8387
The Z- score value rounded to nearest tenth is -0.8
The correct answer choice is A. -0.8
Answer:
The volume of the ball is 256 cm³
Step-by-step explanation:
we know that
The density is equal to the ratio of the mass by the volume
D=m/V
Solve for V
The volume is equal to the ratio of the mass by the density
V=m/D
In this problem we have
m=128 g
D=0.5 g/cm³
substitute
V=128/0.5=256 cm³
Answer:
it is 9a+6y+10
