Answer:
We conclude that a researcher used simple random sample.
Step-by-step explanation:
We know that select a sample of five children from a class of 30, a researcher puts each child’s name on a slip of paper, then shuffles the papers in a hat and randomly picks five names.
We conclude that a researcher used simple random sample.
Because every children has an equal chance of being included in the sample.
Well you have to start of by finding the circumference of the tire, which you can do with the equation 2πr. If the radius is 1.2 feet, you just plug this into the equation to get 2.4π, which we will round to 7.5. After 10 rotations, you should've traveled approximately 75 feet
Not A.(17 is a common factor)
B. only common factor is 1
not C (7 is a common factor)
D. only common factor is 1
Both B and D are relatively prime.
Answer:
I think [(-4)^4]^5, but I'm not completely sure
Step-by-step explanation:
1.0995116e+12 greater than -4.7223665e+21
[(-4)^4]^5=1.0995116e+12
-[(4^12)^3=-4.7223665e+21
