given,
2r = 7/10
r= 7/10*1/2
r= 7/20
Answer:
Step-by-step explanation:
we know that
The density is equal to the mass divided by the volume
Let
x-----> the mass of marble
y----> the volume of marble
z----> the density of marble
in this problem we have
substitute and solve for x
I believe the problem ask for s which is the standard
deviation. We must recall that the formula for z statistic is stated as:
z = (x – x over bar) / s
Where,
z = z statistic = 2.5
x = sample value or sample score = 102
x over bar = the sample mean or sample average = 100
s = standard deviation = unknown
Rewriting the equation in terms of s:
s = (x – x over bar) / z
Substituting the given values into the equation:
s = (102 – 100) / 2.5
s = 0.8
Therefore the standard deviation s is 0.8
Answer:
20.4cm²
Step-by-step explanation:
base= 10.2
height= 2
10.2×2=20.4cm²
I would think you would use 1/3 of a cup but I am not sure.Hope it helps!
