When dividing with fractions, you "keep, change, and flip" the problem.
This means that the 4 becomes 1/4, so they are equal to each other.
What it looks like:
÷ 4 -> x 
= keep
÷ = change to x
4 = flip to
Answer:
about 117 times
Step-by-step explanation:
No. of possible outcomes of a cube: 6
2 out the 6 possible outcomes are less than 3,
and therefore, No. of favorable outcome: 2
P(less than 3)= No. of favorable outcome / No. of possible outcomes
=2/6 => 1/3
if you roll a standard number cube 350 times then,
Prediction= number of rolls x (P(less than 3))
=350 x 1/3
≈117 times.
Answer:
37

Answer:
1.) No ;
2.) - 0.931
3.) 0.1785
Step-by-step explanation:
Given :
μ = 84.3 ; xbar = 81.9 ; s = 17.3
H0 : μ = 84.3
H1 : μ < 84.3
The test statistic :
(xbar - μ) ÷ (s/√(n))
(81.9 - 84.3) / (17.3/√45)
-2.4 / 2.5789317
= - 0.9306
= - 0.931
Using the test statistic, we could obtain the Pvalue : df = n - 1 ; df = 45 - 1 = 44
Using the Pvalue calculator :
Pvalue(-0.9306, 44) = 0.1785
Using α = 0.05
The Pvalue > α
Then we fail to reject H0; and conclude that there is no significant evidence to support the claim that the mean waiting time is less than 84.3
