Answer:
This is the identity property of addition which states that when you add zero to a number the results is the number itself.
Step-by-step explanation:
Hello,
Identity is a number<em> t</em> that when added to other numbers it gives the same number<em> t. </em>In mathematics, the additive identity is always 0. In this property a number is added to 0 where the sum is always the number. For example 0+ 96= 96.
Other properties in math that involve addition are the commutative property, associative property and the distributive property.
In the commutative property, when two numbers are added, the sum is the same regardless of the order of the addends. For example, 3+2=2+3
The associative property states that when three or more numbers are added, the sum is the same regardless of how the addends are grouped.For example (2+3)+4 = 2+(3+4)
The distributive property states that the sum of two numbers multiplied by a third number is equal to the sum of each addend multiplied by the third number. For example 2*(9+1)=2*9 +2*1.
Hope this Helps.
Answer:
3
Step-by-step explanation:
set the two equations equal to each other
2y+3 = 5y-6
add 6 to both sides
subtract 2y from both sides
9=3y
divide both sides by 3
y=3
Answer:
: mu1-mu2=0
: mu1-mu2>0
Step-by-step explanation:
Let mu1 be the mean amount of time (in hours) per domestic car repair
and mu2 be the mean amount of time (in hours) per foreign car repair
According to the claim of the automobile technician, the mean amount of time (in hours) per domestic car repair is <em>more than</em> that of foreign cars.
Then <em>null and alternative hypotheses</em> can be stated in <em>symbolic</em> form as
- : mu1-mu2=0
- : mu1-mu2>0
