Answer:
The probability is 
Step-by-step explanation:
From the question we are told that
The percentage that are on time is p = 0.76
The sample size is n = 11
Generally the percentage that are not on time is



The probability that no more than 4 of them were on time is mathematically represented as

=> 


Answer:
For
we will have positive values only.


Rest are positive so will give positive values out of the modulus function.
Step-by-step explanation:
The absolute value of any number is its positive value only.
As for example
and
both are having equal distance from
in a number line, one on the left other on the right side of the number line but are equidistant from
.
So absolute value of a number is its distance on number line from reference point
.
One by one we will work with all of our question.





So we have to take the positive number out of the modulus function that is also called absolute value.
Answer:
y = 56/3
Step-by-step explanation:
Distribute:
37 - (y - 19) = 2y
37 - y + 19 = 2y
Add the numbers:
37 - y + 19 = 2y
56 - y = 2y
Rearrange the terms:
56 - y = 2y
-y + 56 = 2y
Solution:
y = 56/3
Add q/c to the side with k and get q/c-k=m
