How many feet are 48 inches in a sentence?
There are 12 inches in one foot, so 48 divided by 12 equals 4. So 48 inches is equal to 4 feet
How do you get the answer of a median?
take your list of numbers and put them in numerical order then count the number
Note: if you don't get a number left then you add the two numbers and divide by 2
example 1 (odd): 1 3 5 6 9 the median is 5
example 2 (even): 124679 add4+6+10 divided by 2 is 5 the median is 5
How many 10 digit numbers can be formed using 0123456789?
Assuming that numbers with a leading zero is not permitted,
the answer is 9*9! = 3,265,920.
If leading 0s were permitted, the answer would have been 3,628,800
What is the value of relative error if the absolute error is 10?
The relative error depends on the true value of the measurement. That information has not been provided.
How many five-digit whole numbers can be made with 1 2 3 and 4?
1024
If you're not allowed to use each digit more than once, then you can't make any 5-digit numbers, since you only have 4 digits to use.
I you can use each numeral (1, 2, 3, or 4) as many times as you want, then there are 4 ways to fill each position in the 5-digit number. The total number of possibilities is 45 = 1024.
Why is the mean and median not pratical when it comes to the mode?
The three are different measures of central tendency. None of them are substitutes for the other and, except in symmetric unimodal distributions, none of them can be used to estimate another.
How many 4 number combinations are there in the numbers 0 to 2?
Since there are only 3 digits available, repetition must be allowed.
In that case, there are 30 combinations.
Compute the variance (or its square root , standard deviation) of each of the data set.
Set 1: standard deviation = 10.121
Set 2: standard deviation = 12.09
Set 2 shows more variation around the mean.

How many 4 digit combinations can be made with 4 7 0 2?
24 without repeating digits: 4702 4720 4072 4027 4270 4207 7402 7420 7042 7024 7240 7204 0472 0427 0742 0724 0247 0274 2470 2407 2740 2704 2047 and 2074.
How do you find the range between the numbers -54 and 119?
to find the range of numbers, you take the largest number and subtract the smaller number. 119-(-54)=119+54=173
Assuming P(B) = 1/2 and P(G) = 1/2, the expected ratio of boys to girls would be:
B/G = 1.
Explanation:
Suppose 16 families. On their first child there would be 8 boys and 8 girls. From the
8 families that would try again their would be 4 girls and 4 boys. From the 4 families that would try again there would be 2 girls and 2 boys and from the 2 families that
would try again there would be 1 girl and one boy. Form the last family to try again
the chances of getting a boy or a girl is 1/2. So in a larger population than 16 families
half the time they would get a boy and half the time a girl. The relation of boys to
girls end up to be 1 to 1.
Better to plot the subjects' ages on the X-axis (horizontal) and their years of education on the Y-axis (vertical).
What is one thing that every equation contains?
An "equals" sign. That's why it is an equation, two parts are equal.
How many meters are there in 91.9 decimetres?
There are 10 decimetres in one metre. Therefore, 91.9 decimetres is equal to 91.9/10 = 9.19 metres.
