Answer:
f(j) = 6j + 5 if f(1/3)
f(j) = 6(1/3) + 5
f(j) = 2 + 5
f(j) = 7
Step-by-step explanation:
- replace j by 1/3
- distribute 6(1/3)
- do addition
Answer:
A.) Population : All employees at a firm
B.) μ = 5.4
C.) Sample : 80 employees at a firm
D.) Sample mean, x bar = 4.5
Step-by-step explanation:
From the question :
E.)
H0: μ ≥ 5.4
H1 : μ < 5.4
F.)
If Pvalue < α ; Reject H0
G.)
Test statistic :
(xbar - μ) ÷ (s/sqrt(n))
(4.5 - 5.4) ÷ (2.7/sqrt(80))
-0.9 ÷ 0.3018691
= - 2.98
H.)
Pvalue fro Zscore calculator, α = 0.10 = 0.002882
I.)
Decision :
0.002882 < 0.10
Since, Pvalue < α ; We reject the Null
J.)
We Can conclude that the true mean number of sick days for all employees of the firm has decreased after telecommuting was introduced
Answer:
The Multiplication property
Step-by-step explanation:
The Multiplication property by a constant was used
For real numbers a and b, and c different from zero:
If c is positive and 
then 
.
If c is negative and then 
.
In this case we have
Then 
Finally
Answer:
1) hypotenuse = 5
2) leg = 2.65
Step-by-step explanation:
1) x² = 3² + 4² = 9 + 16 = 25
x = √25 = 5
2) x² = 4² - 3² = 16 - 9 = 7
x = √7 = 2.65
Step-by-step explanation:
We have (n + 2)/5 = 14.
=> (n + 2) = 14 * 5 = 70 (multiply 5 on both sides)
=> n = 70 - 2 = 68. (subtract 2 on both sides)
Hence the number n is 68.
