Mixed numbers are basically sometimes a sign of division. You need to turn the mixed number into an improper fraction.
Steps:
Multiply the whole number by the denominator of the fraction and then add that product to the numerator. Leave the denominator as it is before.
Example:
2 1/4
2x4=8
8+1= 9
Answer: 9/4
Then you can divide!
Step-by-step explanation:
The difference in the formula of population and sample variance can be explained as:
Population variance is said to be the value of variance that is calculated from population data, whereas sample variance refers to the variance calculated from sample data. This is the reason why value of denominator in the formula for variance in case of sample data is ‘n-1’, while it is ‘n’ for population data. Hence, the result of both variance and standard deviation derived from sample data is larger than those found out from population data.
Answer:
C 10 columns and 12 rows
Step-by-step explanation:
c = columns
r = rows
5c + 5c = 10c
6r + 6r = 12r
10 columns and 12 rows
The answer is C
Answer:
I think the answer is -25
Step-by-step explanation:
Answer:
y=4x+1
Step-by-step explanation:
First find the gradient of the straight line
Then substitute the gradient in the formula y=mx+c.
Substitute one of the given coordinates in the line to find the value of c.
After finding the value of c substitute it in the formula but do not write the values of x and y in the formula
