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.

Answer:
5/6
Step-by-step explanation:
Suppose x = 0.83 (3 repeating).
Multiply both sides by 10:
10x = 8.3 (repeating 3)
Now, multiply both sides by 10 again:
100x = 83.3 (repeating 3)
So, we have:
100x = 83.3 (repeating 3)
10x = 8.3 (repeating 3)
We see that if we subtract these two equations, the repeating 3s cancel out, and we're left with:
100x - 10x = 83 - 8
90x = 75
x = 75/90 = 5/6
Thus, the answer is 5/6.
Hope this helps!
Answer: The given statement is FALSE.
Step-by-step explanation: Given that Mrs Adams buys 4 bananas and 6 apples.
We are to check whether the following statement is true or false :
" the ratio of bananas to apples is 6 : 4".
The number of bananas, b = 4
and
the number of apples, a = 6.
Therefore, the ratio of number of bananas to number of apples is given by
That is, the ratio of number of bananas to number of apples is 2 : 3.
Thus, the given statement is FALSE.
