Hello!
To find the surface area of a cube you do
where "a" is the length of one of the sides.
So
= 1350
the answer is 1350mm
Hope this helps!

chuck knows that 1/50 = 0.02 how can he use this information to find the fraction form for the decimal 0.86?

Step-by-step explanation:
The plumber's daily earnings have a mean of $145 per day with a standard deviation of
$16.50.
We want to find the probability that the plumber earns between $135 and
$175 on a given day, if the daily earnings follow a normal distribution.
That is we want to find P(135 <X<175).
Let us convert to z-scores using
This means that:
We simplify to get:
From the standard n normal distribution table,
P(z<1.82)=0.9656
P(z<-0.61)=0.2709
To find the area between the two z-scores, we subtract to obtain:
P(-0.61<z<1.82)=0.9656-0.2709=0.6947
This means that:
The correct choice is C.
Answer:
-6
Step-by-step explanation:
= -3 × -3
-3 × -3 = 9
7 × -3 =-21
9 - 21 +6 = -6
