Answer:
c. 0.1151
Step-by-step explanation:
d) the probability that, on average, fish are larger than 86 centimeters in length.The area under part of a normal probability curve is directly proportional to probability and the value is calculated as
z = (x₁−x) /σ
where z = propability of normal curve
x₁ = variate mean = 86cm
x = mean of 80cm
σ = standard deviation = 5cm
applying the formula,
z= (86-80)/5
z = 6/5 =1.2
Using a table of partial areas beneath the standardized normal curve (see Table of normal curve, a z-value of 1.2 corresponds to an area of 0.3849 between the mean value. but, because the standard curve has 0.5, then will minus 0.3849 from 0.5= 0.5 - 0.3849 = 0.1151
Thus the probability of a fish are larger than 86 centimeters in length is 0.1151
$66. 10% of $60 is $6, so add that to $60.
Hello there!
So, as we see here, we can see that they start out with 20,000 members. 25% of 20,000 would be 5,000 members.
So, every year, they lose 25% which is 5,000 members of they team. But then they gain 10,000 more.
So, practically, they get 5,000 every year even though they get 25% off.
5,000 would be the answer.
