The answer is z = y over cos 50 degrees
2 1/3 / 1 3/5 7/3 / 8/5 7/3 * 5/8 7*5 = 35 3*8 = 24 35 / 24 1 and 11/24 1 and 11/24 1 and 11/24
Hope this helps!
Answer:
29+/-2.26
= (26.74, 31.26) characters
Therefore the 95% confidence interval (a,b) = (26.74, 31.26) characters
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 29 characters
Standard deviation r = 6 characters
Number of samples n = 27
Confidence level = 95%
z value(at 95% confidence) = 1.96
Substituting the values we have;
29+/-1.96(6/√27)
29+/-1.96(1.154700538379)
29+/-2.263213055223
29+/-2.26
= (26.74, 31.26) characters
Therefore the 95% confidence interval (a,b) = (26.74, 31.26) characters
Step-by-step explanation:
length=x
width=x-1
x + x + (x-1) + (x-1) = 54
4x - 2 = 54
4x = 56
x = 14 ft
x = 14 ft
x - 1 = 14 - 1 = 13 ft
x = 14 ft
x - 1 = 14 - 1 = 13 ft
Perimeter= x + x + (x-1) + (x-1)
54 ft = 14 + 14 + (14 - 1) + (14 - 1)
54 ft = 28 + (13 +13)
54 ft = 54 ft
