Method One:
Step One: Figure out how long the width is, witch is 19 feet.
Step Two: Multiply 2*19 and 3*11 because it is 2 times as long and three times as wide
Step Three: Add 38+33
The new perimeter will be 71 feet.
Yes they are equivalent fractions. If you multiply by 2 on both numbers for 2/3, you get 4/6.
Answer:
Explained below.
Step-by-step explanation:
According to the Central Limit Theorem if an unknown population is selected with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from this population with replacement, then the distribution of the sample means will be approximately normal.
Then, the mean of the sampling distribution of sample means is given by,
And the standard deviation of the sampling distribution of sample means is given by,
So, if the sample of daily calcium intake of Americans collected is more than 30, then the sampling distribution of will be approximately normal.
3x and 2x are alike terms, as they have the same variable
