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
I think it is 6/16 because if you add 1/4 with 5/12
Answer:
Ã=7/6
Step-by-step explanation:
<em>2/3(x -6) -y </em>
<h3><em>put the value of x= 9 and y=5/6 </em></h3>
=2/3(9-6)-5/6
=2/3×3-5/6
=2/1-5/6
=12-5/6
=7/6
