Ok, so u would times 4 by 7 because there is 7 days in a week and that would equal 28. After, do 2194 and divide that by 49 hours per week. That’s all I know so far
Answer:
The standard error of the mean is 10.11 points
Step-by-step explanation:
Standard error of mean = t×sd/√n
sd = 115 points, n = 500, degree of freedom = n-1 = 500-1 = 499, assuming a 95% confidence level, t-value corresponding to 499 degrees of freedom and 95% confidence level is 1.96501
Standard error of mean = 1.96501×115/√500 = 10.11 points (to the nearest 100th)
3 49/90
Step-by-step explanation:
7 11/78-4 1/15
(7-4)+(11/18-1/15)
3+49/90
3 49/90
3 19/90 or
3.5444444444
Answer:
2 1/2 or 2.5
Step-by-step explanation:
1/2x +4=9
-4 -4
1/2x= 5
/1/2 /1/2
x= 2 1/2 or 2.5
F(x)=x^2+3x-7, x=3
f(3)=3^2+3(3)-7
f(3)=9+9-7
f(3)=11
