Answer:
Option A: 3.59% is the correct answer
Step-by-step explanation:
Z-score is used to calculate the probabilities when mean and standard deviation is given.
Given
Mean = μ = 21
SD = σ = 5
We have to find the probability of selling 12 or less water heaters so our x value is 12
x = 12
The z-score of a value is calculated as:
z-score = (x-μ)/σ
Putting the values
Now z-score table will be used to calculate the probability for z= -1.8
So we will go for the row with -1.8 and column 0, which gives us: 0.03593
As we have to calculate the probability in percentage
Hence,
Option A: 3.59% is the correct answer
The answer is C :108! have a good night
Answer:
-7, -10
Step-by-step explanation:
The sequence seems to be decreasing by 3. Therefore, to find the next two terms simply subtract 3 from the previous term.
Rule: x - 3
-4 - 3 = -7
-7 - 3 = -10
Answer:
23
Step-by-step explanation:
Insert 3 for "x"
f(3)=23
The number that still remains under the radical when the expression is in its simplest form is 8.
<h3>What is a radical?</h3>
A radical refers to a root form. In this case, we can write this number as; 1,250^3/4.
If we try to simplify this in line with the laws of indicies, we have; 4√(1250)^3. If we simpify further, we obtain; (125)4√8.
Thus, the number that still remains under the radical when the expression is in its simplest form is 8.
