Answer:
40 + 24 = 8(5 + 3)
Step-by-step explanation:
Consider the expression 40 + 24. Find the greatest common factor of the two numbers, and rewrite the expression using distributive property
Step 1
We find the GCF
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40
Then the greatest common factor is 8.
Step 2
Rewriting the expression using distributive property.
The factors of 40 and 24 that would give us the sum of 8 is given as 5 and 3
Therefore, using Distributive property
40 + 24 = 8(5 + 3)
Answer:
Measurement error.
Step-by-step explanation:
Measurement Error are the error when there is difference found in true value of data and measured quantity of data. This difference could be found if we are missing some data in the sample.
The error could be reduced by carefully designing the process of data collection and it´s measurement.
Measurement error are classified into two type of error:
- Random error.
- Systematic error.
Answer: The number you reach would be -4
Step-by-step explanation:
Answer:
(a) (6, 2)
Step-by-step explanation:
The system of equations has one of them in y= form, so it lends itself to solution by substitution.
__
Using the equation for y to substitute into the first equation, we have ...
2x -y = 10
2x -(-1/2x +5) = 10 . . . . . substitute for y
2x +1/2x -5 = 10 . . . . . eliminate parentheses
5/2x = 15 . . . . . . . . . add 5, collect terms
x = 6 . . . . . . . . . . . multiply by 2/5
Using the equation for y, we have ...
y = -1/2(6) +5 = -3 +5
y = 2
The solution is (x, y) = (6, 2).
Answer:
B. 61%
Step-by-step explanation:
When we have the standard deviation of a sample, we use the t-distribution.
The width of an interval is related to the margin of error, which is given by the following equation:
M = T*s
In which T is related to the confidence level(and the sample size) and s is the standard deviation of the sample. Higher confidence levels have higher values of T.
A higher margin of error means that the interval is wider. To have a higher margin of error, we desire a higher value of T, which is achieved with a higher confidence level.
So the correct answer is:
B. 61%
