B because 14-5=9 and 9-8= 1
Answer:
A = 173 m²
Step-by-step explanation:
P = 60m = 3L => L = 60 : 3 = 20 m
A = L×h/2 = 20m×17.3m/2 = 10m×17.3m = 173 m²
Lets find the common demoninator of them all, Its 30! so 1/3 of 30= 10
3/5 of 30= 18 7/10 of 30= 21 1/2 of 30 = 15
So that means that 7/10 is the biggest out of them all, That means carlos ran the greatest distance!

Answer:
CI(99%) = ( 0.93 , 2.07)
Therefore at 99% confidence interval (a,b) = ( 0.93 , 2.07)
Critical value z(at 99% confidence) = z(0.005) = 2.58
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 gain x = 1.5
Standard deviation r = 0.58
Number of samples n = 7
Confidence interval = 99%
Critical value z(at 99% confidence) = z((1-0.99)/2)
z(0.005) = 2.58
Substituting the values we have;
1.5+/-2.58(0.58/√7)
1.5+/-2.58(0.2192)
1.5+/-0.565536
1.5+/-0.57
= ( 0.93 , 2.07)
Therefore at 99% confidence interval (a,b) = ( 0.93 , 2.07)
