A number cube is rolled 10 times. An even number comes up 6 times. What is the experimental probability of an even number coming
1 answer:
Answer:
B
Step-by-step explanation:
Experimental probability is the ratio of the number of times an event occurs to the total number of trials or times the activity is performed.
A number cube is rolled 10 times, so
<u>Number of trials or times the activity is performed</u> = 10.
An even number comes up 6 times, so
<u>Number of times an event occurs</u> = 6.
Hence, the experimental probability is

Answer:
(507.05, 592.95)
Step-by-step explanation:
Given data:
sample mean = $550, sample standard deviation S = $60.05
95% confidence interval , n = 10
For 95% confidence interval for the mean
mean ± M.E.
where M.E. is margin of error =
Substituting the values in above equation
= 2.62×18.99
=42.955
= 550±42.95
=(507.05, 592.95)
