Mean=5
sd=2
Using Z(x)=(x-mean)/sd
Z(2)=(2-5)/2=-1.5
Z(6)=(6-5)/2=0.5
Therefore
probability of finding a spot between 2 and 6 minutes is
P(x<6)-P(x<2)
=P(Z<0.5)-P(Z<-1.5)
=0.6915-0.0668
=0.6247
=>
More than half of the students (62.5%) finds a space between 2 and 6 minutes.
Answer:
Pyramid A is 20.40 times smaller than pyramid B.
Step-by-step explanation:
It is given surface area of pyramid A is
Surface area of pyramid B is
We have to find that how many times pyramid A is smaller than pyramid B
For this we have to divide surface area of pyramid B by surface area of pyramid A
Therefore ,
So pyramid A is 20.40 times smaller than pyramid B.
Answer:
The wax will fill the mold a bit more than halfway.
Step-by-step explanation:
The volume of a sphere with radius is:
.
The radius of this sphere of wax is ; Its volume would be:
.
Assume that the wax here does not evaporate, combust, or otherwise disappear. .
The volume of a rectangular prism is equal to .
For this mold with a rectangular prism shape:
.
Half of that would be:
.
Compare these two volumes to the volume of wax available:
.
In other words, the wax will fill the mold a bit more than halfway, but not completely.
I think answer should be the first option please give me brainlest let me know if it’s correct or not okay thanks bye
