Answer:
r = 4.417
Step-by-step explanation:
in order to calculate the radius of a sphere
given that
volume of sphere = 361
π = 3.14
radius = ?
recall that the volume of a sphere = 4/3 πr³
361 = 4 /3 × 3.14 × r³
361 = 12.56r³/3
cross multiply
361 × 3 = 12.56r³
1083 = 12.56r³
divide both sides by 12.56
1083/12.56 = 12.56r³/12.56
86.226 = r³
find the cubic root of both sides
r = ∛86.226
r = 4.417
therefore the radius of the sphere is evaluated to be 4.417
Answer:
If a 1% level of significance is used to test a null hypothesis, there is a probability of ____ less than 1%______ of rejecting the null hypothesis when it is true
Step-by-step explanation:
Given that a hypothesis testing is done.
Level of significance used is 1%
i.e. alpha = 1%
When we do hypothesis test, we find out test statistic Z or t suitable for the test and find p value
If p value is < 1% we reject null hypothesis otherwise we accept null hypothesis.
So p value can be atmost 1% only for accepting null hypothesis.
So the answer is 1%
If a 1% level of significance is used to test a null hypothesis, there is a probability of ____less than 1%______ of rejecting the null hypothesis when it is true.

<span>A jar contains 2 red and 4 blue marbles. A marble is drawn from the jar. What is the probability that a red marble will be drawn?
So lets solve this!
Probability is an event of chance; an occurrence of chance.
The probability that a red marble will be drawn is 2/6
Simply 2/6 which is 1/3
Thus, your answer is option C.
Hope I helped :D
