Answer:
20 sec
Step-by-step explanation:
the average adult male can run 100 m in 18 seconds, you could reasonably assume 20 seconds is a fair answer
Answer:
r=
Step-by-step explanation:
Circumference formula: 2πr
2πr=15
Divide 2π on both sides.
So since it won't be a integer you can leave it live that so your final answer will be:
r=
Answer:
Step-by-step explanation:
Given
See attachment for line segment RQ
of RQ
Required
The coordinates of P
Using line segment ratio formula, we have:
If P is at:
Then:
Solve
Multiply by 6
By comparison
From the attached line segment
So, we have:
Answer:
The correct value is t* = 1.690
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 36 - 1 = 35
90% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 35 degrees of freedom(y-axis) and a confidence level of . So we have T = 1.69, which is the answer to this question.
