A’(-8,-4) B’(4,-4) C’(4,8) D’(-8,8)
Because the scale factor is 4 all you do is multiply your coordinates by 4
Answer:
Step-by-step explanation:
A matched pair t test is one in which the set of data is divided into two sets of data and the test is done to test the difference between the pairs. Sometimes this is called paired t test.\
This is done normally where one group of sample or population can be paired with other group of sample /population.
Hence
A .Measurements of annual income for each twin for 100 randomly selected pairs of twins -- True
B. Measurements of annual income for both individuals in pairs formed by matching 100 people from State A and 100 people from State B based on level of education -- True
C. Measurements of annual income for both individuals in pairs formed by assigning 100 people to pairs at random -- True
D. Measurements of annual income recorded for both spouses of 100 randomly selected married couples --False here we cannot say paired as these people are not grouped under the same conditions.
Answer:
Since b^2 -4ac = 256 we have 2 real distinct root roots
Step-by-step explanation:
4x^2+12x=7
We need to subtract 7 to get it in the proper form
4x^2+12x-7=7-7
4x^2+12x-7=0
The discriminant is b^2 -4ac
when the equation is ax^2 +bx+c
so a =4 b=12 and c=-7
(12)^2 - 4(4)(-7)
144 +112
256
If b^2 -4ac > 0 we have 2 real distinct roots
If b^2 -4ac = 0 we have one real root
If b^2 -4ac < 0 we have two complex root
Since b^2 -4ac = 256 we have 2 real distinct root roots
9x(12+7)
distribute the 9x
108x+63
Answer:
<u>Janet's interest is $3.90 every month.</u>
Step-by-step explanation:
First, you need to set up a proportion to find Janet's interest:
0.65%/100 = x/600
Step 1: Cross-multiply.
0.65/100/100 = x/600
(0.65/100)*(600)=x*(100)
39/10=100x
Step 2: Flip the equation.
100x=39/10
Step 3: Divide both sides by 100.
100x/100=39/10/100
x=39/1000 (0.039)
Then move the decimal twice to the left to find the dollar amount:
0.039 ⇒ 3.90
Janet's interest is $3.90 every month.
