Answer:
1
Step-by-step explanation:
listing the factors of both numbers
factors of 10 are 1, 2, ,5, 10
factors of 3 are 1, 3
the only common factor to both is 1
the greatest common factor is 1
Answer: 3900
ft^3
if you use the formula on how to find the volume of a cone
V=r^2*h/3
you will insert 30 where the r is, 13 in where h is, after you just solve that and your answer would be 3900 ft^3
A. 5500x(1+5%)=$5775
b. 5775x(1+5%)=$6063.75
Those are your answers.
Answer:
1. -5.5 2. 5 3. 5, 5.5
Step-by-step explanation:
For #1 just look at what point it would be towards the y- axis.
For #2 you want to kinda estimate what it would be between.
And lastly #3 they want to see the exact coordinates for Q so, look at the x axis first they the y axis. Remember Run then Jump
Answer:
Yes, there is enough evidence to say the proportions are the same.
Step-by-step explanation:
Null hypothesis: The proportions are the same.
Alternate hypothesis: The proportions are not the same.
Data given:
p1 = 51% = 0.51
n1 = 200
p2 = 48% = 0.48
n2 = 150
pooled proportion (p) = (n1p1 + n2p2) ÷ (n1 + n2) = (200×0.51 + 150×0.48) ÷ (200 + 150) = 174 ÷ 350 = 0.497
Test statistic (z) = (p1 - p2) ÷ sqrt[p(1-p)(1/n1 + 1/n2) = (0.51 - 0.48) ÷ sqrt[0.497(1-0.497)(1/200 + 1/150)] = 0.03 ÷ 0.054 = 0.556
The test is a two-tailed test. At 0.10 significance level the critical values -1.645 and 1.645
Conclusion:
Fail to reject the null hypothesis because the test statistic 0.556 falls within the region bounded by the critical values.
