ANSWER : (9u - 8)2
STEPS:
Step-1 : Multiply the coefficient of the first term by the constant 81 • 64 = 5184
Step-2 : Find two factors of 5184 whose sum equals the coefficient of the middle term, which is -144 .
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -72 and -72
81u2 - 72u - 72u - 64
Step-4 : Add up the first 2 terms, pulling out like factors :
9u • (9u-8)
Step-5 : Add up the four terms of step 4 :
(9u-8) • (9u-8)
Which is the desired factorization
Answer:
0.25
Step-by-step explanation:
Answer:
x=-3
Step-by-step explanation:
F(x) just means X.
0=x+3
0-3=x+3-3
-3=x
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.
