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
Answer:
(4x + y)(3x-5x)
Step-by-step explanation:
X = y - 5
x = 1 - y / 3

Answer:
660
Step-by-step explanation:
First, to find out how much money they have collected so far, you need to add 7100 + 1300 which is 8400. 8400= $8.40. So now you know that they have collected 8.40, you need to subtract 1500-840 which = 660
Hope this helps!
