Answer:
Cedric's share=$120
Abel's share=$60
Step-by-step explanation:
Abel will receive half as much as Cedric
Let
Cedric's share=x
Abel's share = 1/2 of x
Total money=$180
x + 1/2x = 180
2x+x/2 =180
3/2x=180
Divide both sides by 3/2
x= 180÷3/2
=180 × 2/3
=360/3
=120
Therefore,
Cedric's share = x = 120
Abel's share=1/2x
=1/2 × 120
=120/2
=60
Cedric's share=$120
Abel's share=$60
Answer:
One sample t-test for population mean would be the most appropriate method.
Step-by-step explanation:
Following is the data which botanist collected and can use:
- Sample mean
- Sample Standard Deviation
- Sample size (Which is 10)
- Distribution is normal
We have to find the best approach to construct the confidence interval for one-sample population mean. Two tests are used for constructing the confidence interval for one-sample population mean. These are:
- One-sample z test for population mean
- One-sample t test for population mean
One sample z test is used when the distribution is normal and the population standard deviation is known to us. One sample t test is used when the distribution is normal, population standard deviation is unknown and sample standard deviation is known.
Considering the data botanist collected, One-sample t test would be the most appropriate method as we have all the required data for this test. Using any other test will result in flawed intervals and hence flawed conclusions.
Therefore, One-sample t-test for population mean would be the most appropriate method.
Answer:
∠ZXY and ZX
XYZ is not found on the diagram, as there is no line going from Z to Y, and YX is not a line segement in the diagram, its a full line.
The rate of change is shown to the right of the second graph as being -2
At 5 to 6 the average rate of change is -11, so at 6 to 7 the rate of change would be -11-2 = -13, then from 7 to 8 it would be -13-2 = -15.
The answer is D. -15
Sorry but there is no question
