The first thing we should know is the definition of commutative property.
Commutative property:
The distributive property of multiplication over addition in elementary algebra is that in which the result of a number multiplied by the sum of two or more addends is equal to the sum of the products of each summand by that number. In algebraic terms we have then:
4 * ((2 * 0.75) + (3)) = (8 * 0.75) + (4 * 3) = 6 + 12 = 18 $
answer:
the total cost of these parts is $ 18
Step-by-step explanation:
All are not correct way to name the angle because the angle'p' isn't pointed in the line.
Answer:
sorry only doing the ones i know how to do
b) for the histogram, just write all the numbers on the table on the bottom, theres 13 lines but 2 repeats so it should be even. on the side write a range of minutes
c) mean = 7.8 ; standard deviation = 3.13
d)
min = 2
max = 13
range = 11
q1 = 5.5
q3 = 10.75
iqr = 5.25
median = 8
what does iqr represent? it represents the middle 50% of all the values
e) write the numbers from the table without repeats and mark them how many times theyre written
Answer:
Step-by-step explanation:
Additive identity is a property that involves the sum of two or more integers in an equation without compromising the equality of the equation.
Given the equation
(5+2)+n = 7+n
We can see that the right hand side of the equation is derived from the left hand had by addition of the values in parenthesis.
Given the right hand side;
= 5+2+n
= (5+2)+n
adding the expression in parenthesis will give;
= 7 + n
Since we added the expression in parenthesis to arrive at the expression at the right hand side, hence additive identity was used in the calculation.
Answer:
4 ²/3
Step-by-step explanation:
( 5+2) ×( 6-4) / ( 2+1 )
= (7)×(2) / 3
= 4 ²/3
