The vertices of triangle QRS have coordinates Q(1, −2), R(3, −2), and S(2, −4). The coordinates are the coordinates of the vertices of triangle QꞌRꞌSꞌ when triangle QRS is reflected across the x-axis <span>Qꞌ(1, 2), Rꞌ(3, 2), Sꞌ(2, 4). The answer is letter B.</span>
Get rid of the decimal first.
-0.875*1000
-875/1000=-0.875
Simplify it since both denominator and numerator is divisible by 5
1/5(-875/1000)
-175/200
Still divisible by 5
1/5(-175/200)
-35/40
Keep going
-7/8
There, now it can’t be more simplified.

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
