Answer:
perimeter = 56 m
area= 196 m^2
Step-by-step explanation:
perimeter = 4 x sides = 4 x 35(2/5) = 4 x 14 = 56 m
area= sides^2 = (35 x = 14^2 = 196 m^2
Answer with explanation:
Let p be the population proportion.
Given : The chain will open if there is evidence that more than 5,000 of the 20,000 households in the area are equipped with Blu-ray players.
i.e.
Since alternative hypothesis is right-tailed , so the test is right-tailed test.
Also, Sample size : n= 300 ,
Sample proportion:
Test statistic:
i.e. Observed test statistic Value = 2.80
(A) is right option.
Critical value for 5% significance level for right tailed test :-
Since , the observed z-value is greater than the critical value , so we reject the null hypothesis.
Conclusion : We have sufficient evidence to supposrt the alternative hypothesis.
So, The chain will open if there is evidence that more than 5,000 of the 20,000 households in the area are equipped with Blu-ray players.
The answer is B. Here are some more words to meet the 20 word requirement.
Answer:
x=16
Step-by-step explanation:
1. Simplify 9/12 to 3/4.
2. Multiply both sides by x.
3. Simplify 3/4x to 3x/4
4. Multiply both sides by 4.
5. 12x4=28
6. Divide both sides by 3.
7. Simplify 48/3 to 16.
Well. U have 6 lamps and we r turning in 3 and the probability of 1 being red is 16.666% u would do 1/6 as a percentage because I are only trying to find if that one is red. Hope this helps! ☺️
