Answer:
The mean amount of cereal in a box must be 23.42 ounces.
Step-by-step explanation:
Let <em>X</em> = amount of cereal in a box.
It is provided that <em>X</em> follows a normal distribution with mean <em>μ</em> and standard deviation <em>σ</em> = 0.25.
If 99% of the boxes contain 24 ounces or more of cereals then the probability statement is:
Use the <em>z</em> table to determine the <em>z-</em>value.
The value of <em>z</em> is -2.33.
Determine the value of <em>μ</em> as follows:
Thus, the mean amount of cereal in a box must be 23.42 ounces.
X= first number
x+1= second number
2x+1=275
2x=274
x+274
x=137 first number
137+1=138 second number
Answer:
Step-by-step explanation:
V = π times r^2 times h (height)
452.16 = 3.14 times r^2 times 4
Multiply 3.14 times 4
452.16 = 12.56 times r^2
Divide 452.16 by 12.56.
452.16 / 12.56 = 36
36 = r^2
The square root of 36 is 6.
So the radius of the cylinder is 6 yards^3.
