Answer:
n=3.8416≅4
So Minimum Sample Size is 4
Step-by-step explanation:
In order to find the minimum sample size, the formula we use will be:
Where:
n is sample size
Z is the distribution
S is the standard deviation
E is the Margin of error
S=3 ,E=3
For Z:
Alpha=1-0.95=0.05
Alpha/2=0.025=2.5%
From Cumulative Standard Distribution Table:
Z at Alpha/2 = 1.960
n=3.8416≅4
So Minimum Sample Size is 4
Answer:
The LCM of 9 and 12 is 36. The GCF is 3
Step-by-step explanation:
To get the Least Common Multiple (LCM) of 9 and 12 we need to factor each value first and then we choose all the factors which appear in any column and multiply them: 2 x 2 x 3 x 3 = 36
To get the Greatest Common Factor (GCF) of 9 and 12 we need to factor each value, that should give you 3.
Answer:
60
Step-by-step explanation:
you should divide 152.4 by 2.54
the result will be 60
Answer:
False.
Step-by-step explanation:
A number is not an element of a number.
A number can be an element of a set. For example, we can say .
BMI = (pounds * 703) / (height^2)
so in the information you are missing the height
let's find it :)
first plug in what you know:
28.5 = (211 * 703) / (height)^2 then solve for (height)
28.5 (height)^2 = (211 * 703) multiplied both sides by (height)^2
(height)^2 = (211 * 703) / 28.5 divided both sides by 28.5
(height) = square root [(211 * 703) / 28.5] square rooted both sides
(height) = 72.143 inches
The healthy BMI is about 25
so 25 = (pounds)(703) / (72.143^2)
25(72.143^2) / (703) = (pounds) divide by 703, multiply by (72.143^2)
pounds = 185
211 - 185 = 26
Therefore Christopher would have to lose 26 pounds.
*Note: If the BMI you wanted to use was not 25, then just replace it like this
(pounds) = (BMI)(72.143^2) / (703) = goal weight
