Answer:
5/7
Step-by-step explanation:
A common factor of 8 can be canceled from numerator and denominator.
40/56 = (5·8)/(7·8) = (5/7)·(8/8) = (5/7)·1 = 5/7
_____
Since you know your multiplication tables, you know that 40 and 56 are both multiples of 8.
__
If you don't know your multiplication tables, you can find the greatest common divisor (GCD) of the two numbers and divide each by that. The GCD can be found using Euclid's algorithm. For that, you divide the larger by the smaller and use the remainder as the new smaller number. The original smaller number is now the larger number. For these numbers, that looks like ...
56 ÷ 40 = 1 r 16
40 ÷ 16 = 2 r 8
16 ÷ 8 = 2 r 0 . . . . . the zero remainder signals that the divisor (8) is the GCD
Now, your fraction is ...
(40/8) / (56/8) = 5/7
Answer:
5/7
Step-by-step explanation:
40/56 both divided by 8 and that is how to get your answer because you can not simplify further
Answer:
The second piece is 5/8 meters.
Step-by-step explanation:
To find the length of the second piece of wire, subtract the length of the first piece of wire from the total.
7/8 - 1/4
Get a common denominator:
7/8 - (1/4) *2/2
7/8 - 2/8
5/8
The second piece is 5/8 meters.
Answer:
Narrower with the same probability of reporting an incorrect interval
Step-by-step explanation:
Increasing the sample size shrinks the width of the confidence interval because the larger the sample size, the more accurate the sample represents the true population.
Standard Error is calculated by multiplying the z or t score of the confidence level by the standard deviation, then dividing by the square root of the sample size
E = z(s)/√n
t scores are used for samples below a size of 30. All t values for 95% confidence are higher than the z score of 1.96, which is used when the sample is greater than 30. This causes a larger value for the error estimate, therefore creating a larger width for the confidence interval.

The solution of the given expression will be -3a - 4b + 8c.'
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is (a + 2b + 3c) − (4a + 6b − 5c). The expression will be solved as below,
E = (a + 2b + 3 c) - (4a + 6b - 5c)
E = a + 2b + 3c - 4a - 6b + 5c =
E = -3a - 4b + 8c
Therefore, the expression will have the solution (a + 2b + 3c) − (4a + 6b − 5c).
