Answer:
9
6
0.15 or if in whole number maybe it was 15
I don’t really understand what you mean though so I had the answers from my own calculator that I use for my homework and did 9/10 = 9 then 6/1 = 6 and then I did 9/10/6/1 = 0.15 then I did the separate 9/6 = 15
I don’t know which answer you need though so I did them all.
Step-by-step explanation:
26-16=10. So I believe it would be 10 girls and 6 boys.
0.0543 nearest whole number is 1 i think
It will be right angle triangle. The two vectors beginning at the same vertex
of a triangle are <2,3> and <-3,2> is classified as right-angled
triangle. It is classified as a right-angled triangle because the dot product
of the vectors are 0.
Answer:
The 99% confidence interval of the population standard deviation is 1.7047 < σ < 7.485
Step-by-step explanation:
Confidence interval of standard deviation is given as follows;
s = 
Where:
= Sample mean
s = Sample standard deviation
n = Sample size = 7
χ = Chi squared value at the given confidence level
= ∑x/n = (62 + 58 + 58 + 56 + 60 +53 + 58)/7 = 57.857
The sample standard deviation s = = 2.854
The test statistic, derived through computation, = ±3.707
Which gives;
1.7047 < σ < 7.485
The 99% confidence interval of the population standard deviation = 1.7047 < σ < 7.485.
