How to find the mean of a data set with a missing value?

1 answer:

5 0

If you are given a mean and asked for one of the data values, you can still use the basic method for determining the mean, but work backwards. Generally we add up all the values and then divide by the number of values. In this case, working backwards, we multiply by the number of values (instead of dividing) and then subtract (instead of adding). You should be left with a data value from the set.

I am a fraction that is equal to 1/6 what am i?

We can multiply both the numerator and denominator by ANY number (as long as you multiply both the numerator and denominator by the SAME number) to get an equivalent fraction

examples would be 2/12 (numerator and denominator multiplied by 2)3/18 (by 3)
4/24 (by 4) etc.

Answer:

Step-by-step explanation:

The volume is calculated like:

V= length* hauteur* wide

V= 5* 2 3/4* 10 1/2

$V= 5*\frac{11}{4} *\frac{21}{2} =\frac{5*11*21}{4*2} =\frac{1155}{8}=144.375 \\=144 \frac{3}{8} in^{3}$

12 times a number plus 26 greater than 6

weeeeeb [17]

Answer:I am a little confused by your wording but I am assuming the question is 12 times what is 26 greater than 6

The answer would be 2.66666666667 which sound incorrect but multiply by 12 and you get 32 and 6 + 26= 32

Answer:

$\sqrt{44} = 2\sqrt{11}$

Step-by-step explanation:

Apply pythagorean theorem:

ABD is a right triangle with angle ADB = 90

hence AD = $\sqrt{AB^{2} - BD^{2} }$ where BD = 10 because it is half of BC

AD = $\sqrt{12^{2}-10^{2} }$ = $\sqrt{44} = 2\sqrt{11}$
