30. 30 is the answer to this question.
Answer:
Distributive
Step-by-step explanation:
1. Distributive Property a • (b + c) = a • b + a • c
2. Commutative Property of Addition a + b = b + a
3. Commutative Property of Multiplication a • b = b • a
4. Associative Property of Addition a + (b + c) = (a + b) + c
Answer:
68.269%
Step-by-step explanation:
We start by calculating the z-scores of both numbers
Mathematically;
z-score = (x-mean)/SD
where x represents the raw score
For 82;
z-score = (82-87)/5 = -5/5 = -1
For 92;
z-score = (92-87)/5 = 5/5 = 1
So the probability we want to calculate would be;
P(-1 < x< 1)
We can use the standard normal distribution table to get this.
By using the distribution, P(-1<x<1) = 0.68269
By converting this to percentage, we have 68.269%

Answer:
The expression representing the volume of the cylinder is
/7 cubic units
Step-by-step explanation:
In this question, we are tasked with finding an expression that represents the volume of a cylinder given the condition that the height of the cylinder is twice the radius of its base.
Now, let's say the radius of the base of the cylinder is x, since the height is twice it, the value of the height h will be 2x
Mathematically, the volume of a cylinder can be calculated using the formula
V = π ××h
where r and h represents the radius of the base and height respectively. Plugging the values, we have;
V = π × × 2
V = 22/7 × × 2
V = /7 cubic units
