Answer:
74.47%
Step-by-step explanation:
Divide the total number of students by the number who passed
passed/total
35/47
0.74468085
As a percent:
0.74468085*100=74.4680851
Rounded to the nearest hundreth:
74.4680851
74.47%
So, 74.47% passed the geometry test
Hope this helps! :)
Answer:
d. 11:15
Step-by-step explanation:
1) officer1: distance 75 miles, velocity 60mil/h; officer2: distance 25 miles, velocity 55mil/h;
2) time, which is spent officer1 is: 75/60=1.25[h]=75 [min]. If the officer1 leaves his office at 10:00, the arrival time is 11:15;
3) time which is spent officer2 is: 25/55=5/11[h]≈27[min]. The arrival time is 10:27.
4) finally, the both officers are in the required location at 11:15.

Answer:
Optin b is right
Step-by-step explanation:
given that the mean of the sampling distribution for the difference in two sample means is 0.
This means that when two sample means are equal we get difference is 0 and this would be the point estimate of mean for differene of means distribution.
Hence the four options given can be analysed
. the two sample means are both 0. -- False need not be 0 but equal
B. the two sample means are equal to each other. -- True
C. the two population means are both 0. -- False need not be 0
D. the two population means are equal to each oth -- False only sample means are 0 and if sample represents population this may be 0
