<h3>What is a normal distribution?</h3>
A normal distribution is a probability distribution that is symmetric around the mean of the distribution. This means that the there are more data around the mean than data far from the mean. A normal distribution is also known as the Gaussian distribution. When depicted on a graph, a normal distribution is bell-shaped.

Step-by-step explanation:
conditions : x≠0 and x≠-a and b≠1
1/(x+a) = b/x ⇌ 1×x = b(x+a) ⇌ x = bx + ba ⇌ (1-b)x = ab ⇌ x = ab/(1-b)
Let the numbers be x and y, then
2x + y = 47 . . . (1)
x + 3y = 56 . . . (2)
(2) x 2 => 2x + 6y = 112 . . . (3)
(1) - (3) => -5y = -65 => y = -65/-5 = 13
From (2), x + 3(13) = 56 => x = 56 - 39 = 17
The two numbers are 13 and 17.

Step-by-step explanation:
L times W times H
Answer: 129
Step-by-step explanation:
It is 129 because y is less than 70 so the greatest possible value for that is 69 and z is less than or equal to 60 so 69 + 60 =129
