Answer:43 teaches
Step-by-step explanation:I research it
Hi there!
2(4z - 9 - 7) = 166 - 46
let's make this a little more simpler...
2(4z - 16) = 120
use distributive property.
multiply 2 and 4z , 2 and -16.
8z - 32 = 120
add 32 on both sides to isolate the variable
8z = 152
divide both sides by 8...
z = 19
So your answer is A. 19
Hope this helped!! :)

Our Order of Operations looks like this:
Parenthesis
Exponent
Multiplication/Division
Addition/Subtraction
Multiplication and division are on the same "level".
When we see them in the problem, we execute the operations from LEFT TO RIGHT. So Shawna should have applied the division before multiplying the 2 and 3. (Because the division is the leftmost operation in the problem).
Answer:
Value of a is 0.667
Step-by-step explanation:
We are given the following in the question:
The rate of customer at an airport follows a Poisson distribution with
The normal approximation of Poisson distribution can be done in the following manner
Formula:
We have to find the value of a such that
More than 50 customers per 5 hours means more than 10 customer per hour.
Thus, we can write
Therefore, value of a is 0.667
