If this is an exponent, it would be 4 x 4 x 4 x 4 x 4 in expanded form.
First, find the mean. You'll need it to compute the variance.
The variance of the sample is then computed with the formula
The standard deviation is the square root of the variance, so
All cubes are similar because every one of them have an equal width and length and height.
I really hope I helped
Answer:
D. A = πr^2
Step-by-step explanation:
The formula of the area of a circle is <u>A = πr^2</u>.
D. 55% of the time
45% of the time it will say positive
The other 55% of the time will come back negative.
