The area under the graph of the continuous uniform distribution is 1.
a. The probability that the value will be between 5 and 7 is the area between 5 and 7.
P(5 \ \textless \  x \ \textless \  7) = \frac{2}{10} = \frac{1}{5}
b. The probability that the value will be between 2 and 3 is the are between 2 and 3.
P(2 \ \textless \  x \ \textless \  3)=\frac{1}{10} 
c. The mean is given by:
\mu=\frac{a+b}{2}=\frac{0+10}{2}=5
d. The variance is given by:
\sigma^2}=\frac{1}{12}(b-a)^{2}=\frac{1}{12}(10)^{2}=8.3333
The standard deviation is:
\sqrt{\sigma} = \sqrt{8.3333} =2.887

Which table represents a nonlinear function?
Setler [38]

Answer:

A

Step-by-step explanation:

Nonlinear would be any function where both values are not changing by some fixed amount. In B, f(x) increases by 1 for every time x increases by 1 so that's linear. For C, f(x) increases by 2 for every time x increases by 1, so that's linear. For D, f(x) increases by 3 for every time x increases by 1 so that's also linear. For A, f(x) does not always change by the same amount, so it's nonlinear.

Why do the inequality signs stay the same in the last two steps of exercise 1
MrRissso [65]
The only reason an inequality would change would be because a number is divided or multiplied by a negative number. So if it stayed the same, then it would be because there was no division or multiplication by a negative number. Hope I helped :)
