Answer:
1/18
Step-by-step explanation:
The spinner has 6 sections.
There are 2 vowels, A and U.
There is only one section with a K.
p(event) = (number of desired outcomes)/(total number of outcomes)
p(vowel) = 2/6 = 1/3
p(k) = 1/6
Each spin is an event. The two events are independent, so the probability of the two events is the product of the individual probabilities.
p(vowel, then K) = p(vowel) * p(k)
p(vowel, then K) = 1/3 * 1/6 = 1/18
Answer: 1/18
I'm not sure what expression you're referring to, but if I wanted to find 36% of 84, I'd divide 84 by 100 and then multiply it by 36.
The answer would be 30.24.
First we have to get x by itself, so we multiply two on each side,
then we get 5x=660/4, I like to simplify here, so I would change it to 5x=165, then we divide each side by 5
x=33

Answer: 6.5 hours
Step-by-step explanation:
You have to find out how long it’ll take, so you divide the total amount by the speed, so 455/70=6.5
Answer:
Test Statistic = 10
Critical Value = 9.488
Step-by-step explanation:
Given :
Grade A _ B _ C _ D _ F
_____14 _ 18 _32_ 20_16
H0 : distribution of grade is uniform
H1 : Distribution of grade is not uniform
Using the Chisquare statistic :
χ² = (observed - Expected)² / Expected
The expected value :
(14+18+32+20+16) / 5 = 20
χ² = (14-20)^2 / 20 + (18-20)^2 / 20 + (32-20)^2 / 20 + (20-20)^2 / 20 + (16-20)^2 / 20
χ² statistic = 10
The χ² critical at df = (n - 1) = 5 - 1 = 4
χ² Critical(10, 4) = 9.488
