After 5 days
You can solve this by plugging 5 in.
-3(5)+42 = 27
4(5)+7 = 27
They have the same result.
Answer:
Step-by-step explanation:
Data given and notation
represent the sample mean
represent the population standard deviation
sample size
represent the value that we want to test
t would represent the statistic (variable of interest)
represent the p value for the test (variable of interest)
Solution to the problem
We need to conduct a hypothesis in order to check if the true mean for the bushlels per acre is not 135, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
And the z statistic is given by:
And replacing we got:
Jessica has 9 more marbles than Jenny.
Answer:
Step-by-step explanation:
When a tangent line is drawn from Q to Z and then from Q to R, what happens that is the length of QZ and QR are the same. So if QZ = 10, the QR = 10. The same occurs at every point outside the circle where a tangent line is drawn from that point to the circle. We are told that YX is 9. That means that YZ is also 9. If XW is 9, then WV is also 9. Here's where the tricky part is. We are given the whole side length of UW as 17, but we need to know each individual part so we can eventually find the length of RS. So we'll keep going the way we were. If XW = 9, the WV = 9. That means that UV is 17 - 9 or 8. So UV = 8. That means that TU is also 8. THAT means that ST is 10 - 8 or 2. And if ST is 2, then RS is also 2. Let's add it all together now:
QZ + ZY + YX + XW + WV + VU + UT + TS + SR + RQ
10 + 9 + 9 + 9 + 9 + 8 + 8 + 2 + 2 + 10 = 76
