D = 5/6 sqrt(h)
7 = 5/6 sqrt(h)
42/5 = sqrt(h)
h = (42/5)^2 = 1,764/25 = 70.56
The height of the mast is 70.56 miles
No, 40,000 has a value of 40,000
Answer:
Tstatistic = - 3.068
Step-by-step explanation:
Given the data: 9.7% 7.4% 5.9% 7.7% 7.5% 8.9%
Mean titanium > 9.5%
Test statistic :
(m - μ) / (s/√n)
From the data: obtain the sample mean and standard deviation
From the data given ;
Calculate the same mean and standard deviation :
Using calculator :
Sample mean (m) = ΣX / n
Sample size (n) = 6
m = 47.1 / 6 = 7.85
Standard deviation (s) :
Using calculator = 1.317
Hence,
(m - μ) / (s/√n)
Tstatistic = (7.85 - 9.5) / (1.317/√6)
Tstatistic = - 1.65 / 0.5376629
Tstatistic = - 3.068
54 yards =
4937.76 centimeters
There is a sign missing, but I think it's a "+" like this:
8-(2+5)
H, ,that is Harry's answer would be:
first the bracket:
8-(7)
and then the whole expression:
8-(7)=1, so H=1
Terry's answer would be:
8-2+5, which we do from left to right:
6+5=11, so T=11
then H-T is 1-11, which is -10.
