The inverse version of a number is it's opposite. The opposite of 3 is -3
Answer: x = 9
We know that 26 and 17 are in a fact family.
Let's see the fact family.
26 - 17 = 9.
So, the answer is 9.
Hope this helps you!
Answer:
a)
The probability of type I error is 0.5
b)
Type II error is an error committed when we fail to reject a false null hypothesis. The probability of Type II error is beta and 1 -beta gives the power of a test.
Step-by-step explanation:
The probability of a Type I error is the probability of rejecting the null hypothesis when it is actually true. In this case;
pr(x>0 / mu =0)
If the mean is 0 and sigma 1 then x has the standard normal distribution. Now, if x has the standard normal distribution then pr(x>0) = 0.5 since the standard normal distribution curve is symmetric about the mean which in this case is 0.
Answer:
A,17.1 in
Step-by-step explanation:
circumference of sphere=2πr
Beetle walks=πr=π×15=15π=15×3.14≈47.1 in
Ant walks=d=2r=2×15=30
difference=47.1-30=17.1 in
