To multiply 9x475 using expanded form and the distributive property, you will break 475 into three numbers, multiply each of them by 9, and add the products together:
475 = 400 + 70 + 5
400x9 = 3600
70x9 = 630
5x9 = 45
3600 + 630 + 45 = 4,275
Uh I think it’s 3? 10-7=3
Answer:
The standard deviation is not greater than 5 mg ()
Step-by-step explanation:
First we need to find the z-score for a 0.05 level of significance.
Looking in the z-table with alpha = 0.05, we have z = 1.645.
Now, finding the standard error of the mean, we have:
The standard deviation with 0.05 level of significance would be:
This deviation is not greater than 5 mg.
Answer: 1.5 kilometers.
Step-by-step explanation:
You need to make the conversion from 500 meters to kilometers.
It is important to remember that:
Then, 500 m to km is:
Now you know that he ran 0.5 kilometers in each of his last three track meets.
To calculate the total amount of kilometers ran in those three meets, you need to multiply 0.5 kilometers by 3. Then:
