Answer:
With the given points your slope would be -5/4.
Answer:C because if you look at 7 the 140 its multiplied by 2 so if you multipy or divide everything by 2 you get C
Step-by-step explanation: It just is G
Answer:
The test statistic is z = 1.865.
Step-by-step explanation:
The test statistic is:
In which X is the sample mean, is the value tested at the null hypothesis, is the standard deviation and n is the size of the sample.
H0: p = 0.11
This means that 0.11 is tested at the null hypothesis, and so:
The engineer weighs 94 bags and finds that 16 of them are over-filled.
This means that:
What is the test statistic?
The test statistic is z = 1.865.
the volume of cylinder is 3.14 r^2×h
480=60(v+s)
480=60v+60s
8=v+s
s=8-v...
480=80(v-s) using s from above we get:
480=80(v-(8-v))
6=v-8+v
6=2v-8
2v=14
v=7, and since s=8-v, s=1
So the rate of the team is 7m/s while the rate of the stream is 1m/s
