2m = 25/2
m= 25/2 divided by 2
m= 25/4
3m= 25/4 x 3
3m= 75/4
so she does 3 miles in 18 3/4 hours
0.0157 the number of zeroes at the end of 1000 is three zeroes therefore u need to ,over the number “15.7” three times to the side and add zeroes in its place.
PLS BRAINLIEST!
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
