Answer:
The required probability is 0.0855
Step-by-step explanation:
Consider the provided information.
The daily revenue has mean $7200 and standard deviation $1200.
The daily revenue totals for the next 30 days will be monitored.
As we know 
Substitute 
in above formula.
From the standard normal table P( Z >1.3693) = 0.0855
Hence, the required probability is 0.0855
Answer:
Discrete variable
Step-by-step explanation:
We are given the following in the question:
Variable:
Total number of points scored in a football game
Discrete and continuous data:
- Discrete data is the data that can be expressed in whole numbers. They cannot take all the values within an interval.
- Discrete variables are usually counted and not measured.
- Continuous variable can be expressed in fractions and can take any value within an interval.
- Continuous variable are usually measured and not counted.
Since, total number of points score in a foot game are expressed in whole numbers and cannot be expressed in decimals, they are discrete variable. They cannot take all the values within an interval and they are usually counted.
Thus,
Total number of points scored in a football game is a discrete variable.
Given equation: 5 to the power of 2 + 8 divided by 2.
First, before we answer this,
let's convert it to numerical form.
=> 5 to the 2th power = 5^2
=> 8 divided by 2 = 8 / 2
Final equation = 5^2 + 8 / 2=> 5 ^ 2 = (5 * 5)
=> 25 + 8 / 2=> 25 + (8 /2)
=> 25 + 4 => 29.
Thus the answer to the given question or equation is 29.<span>

Answer:
0.6154 or 61.54%
Step-by-step explanation:
Machine B output level= 80%
Machine A output level= 20%
Machine B defective rate = 0.04
Machine A defective rate = 0.10
The proportion of total washers that are defective is:
Therefore, the probability that a randomly selected washer was manufactured by machine B, given that it is defective, is determined by the proportion of defective washers produced by machine B divided by the proportion of total defective washers:
The probability is 0.6154 or 61.54%.
