Answer:
44
Step-by-step explanation
4c + d
this is an expression and since they provided c and d it is easy to solve
c = 9 and d = 8. You need to plug in c and d into the expression to solve the problem.
4(9) + (8)
4 times 9 is 36 so it leaves you with 36 + 8
36 + 8 = 44
I hope this helps but basically the concept is just plugging in the numbers in place of the variables. For future problems plug in the numbers given where the variables are.
11 and 11/15 is the answer
Percent of decrease :
Original - New / Original
so...
80 - 52 / 80 ---->
28/80
.35 multiply by 100 to get percent
35% increase Hope I helped if you have any questions let me know! :)
Considering that the value of 126.07 is valid for the population, it is a parameter.
<h3>What is the difference between a statistic and a parameter?</h3>
- If the measure is defined only for the sample, it is a statistic.
- If the measure can be defined for the population, it is a parameter.
In this problem, the mean blood pressure is calculated for all employees, which means that it is valid for the population, hence it is a parameter.
