Answer:
The answer is 22.6kg
Step-by-step explanation:
kilo means 1000 i.e. 10³
Hence,
1 kilogram = 1000 gram
Now,
The both quantities are in kg i.e. 25kg and 2.4kg.
We can add zeros after an integer by putting decimal point after least significant figure hence we can write 25 as 25.0
Taking difference of these two:
25.0-2.4 = 22.6kg
Answer:
D
Step-by-step explanation:
The mean is the average summing all values together and dividing by the number of values been investigated.
Hence since no values exist between 201-350 that means the mean can not be there.

Answer:</h2>
The expression that is equivalent to the given expression is:
<h2>
Step-by-step explanation:</h2>
Two expression are said to be equivalent if by some simplification i.e. by some multiplication or division it could be represented in the same manner.
Here we are given a expression as:
g^{-m} ÷ g^n i.e.
We know that:
Hence, we get:
Answer:
1 cup of heavy cream
27 cups of whole milk
1/3 cups of sugar
7 teaspoons of vanilla extract
(serves 2 peopel)
Step-by-step explanation:
Since the whole thing is serving 4 people....you just have to divide all the ingredients by 2
Answer:
1. 68%
2. 50%
3. 15/100
Step-by-step explanation:
Here, we want to use the empirical rule
1. % waiting between 15 and 25 minutes
From what we have in the question;
15 is 1 SD below the mean
25 is 1 SD above the mean
So practically, we want to calculate the percentage between;
1 SD below and above the mean
According to the empirical rule;
1 SD above the mean we have 34%
1 SD below, we have 34%
So between 1 SD below and above, we have
34 + 34 = 68%
2. Percentage above the mean
Mathematically, the percentage above the mean according to the empirical rule for the normal distribution is 50%
3. Probability that someone waits less than 5 minutes
Less than 5 minutes is 3 SD below the mean
That is 0.15% according to the empirical rule and the probability is 15/100
