Answer:
Step-by-step explanation:
44 = 2 * 2 * 11
= 2² *11
So calculate the probability
that is
(desired outcomes)/(total possible outcomes)
desired oucomes=green
so take the spins from20 and 200 and 2000
tota=20
deriedoutcome=0
0/20=0
total=200
desired outcomes=7
7/200=0.035
total=2000
disired outcomes=95
95/2000=0.0475
average the 3 results
(0+0.035+0.0475)/3=0.027
0.027=x/20
multily both side by 20
0.5
round up
1
the answer is A, 1
The answer is 216
Hope this helps
Answer:
The area of the sector (shaded section) is 29.51 .
Step-by-step explanation:
Area of a sector = (θ ÷ 360)
where θ is the central angle of the sector, and r is the radius of the circle.
From the diagram give, diameter of the circle is 26 m. So that;
r =
= = 13 m
θ = 360 - (180 + 160)
= 360 - 340
=
Thus,
area of the given sector = x x
= x x x 169
= 29.5079
The area of the sector (shaded section) is 29.51 .
Answer:
when the advertiser failed to reject the null hypothesis it means that the belief of the newsletter publisher that ess than 26% of their readers own a Rolls Royce is not supported by statistical evidence at 10% significance level.
Step-by-step explanation:
given that a newsletter publisher believes that less than 26% of their readers own a Rolls Royce.
For marketing purposes, a potential advertiser wants to confirm this claim.
After performing a test at the 0.10 level of significance, the advertiser failed to reject the null hypothesis.
For this the hypotheses would be
H0: p = 0.26
Ha: p <0.26
when the advertiser failed to reject the null hypothesis it means that the belief of the newsletter publisher that ess than 26% of their readers own a Rolls Royce is not supported by statistical evidence at 10% significance level.
