23b^4+(-10b^4)
23b^4-10b^4)
13b^4
I cannot draw a graph so im going to explain
on the bottom u write per month and on the side and then increase the amount of money by 20$.
I’m this you should know that it is best to find the area of each triangle then add them together
As you see the base is 24 so you take half of 24 for the base of your triangles and you get 12
1/2 is one half
TRIANGLE A
A = 1/2( Base (times) height)
A = 1/2(12 (times) 35) = 210
The formula will be the exact same for the other triangle.
When adding the areas up you get 420 squared inches.
Therefore answering is 420 in^2
Answer:
1. T test for independent means
2. T test for dependent means
3. T test for dependent means
Step-by-step explanation:
In number 1, the two groups are unrelated. The first group has 25 subjects and they're all unemployed. The second group has 24 subjects and their employment status is not stated and might not be the same all through. Also, the first group is receiving a new type of job skills program while the second group is taking the standard job skills program.
- The groups in the experiment are unrelated
- The tests in the research are unrelated
- The purpose of the research is unreasonable - the researcher seeks to measure how well all 49 subjects perform on 'a' job skills test! No comparison between the scores or mean scores of the two groups.
In number 2, the researcher uses the same subjects and also measures the same variable but twice. This is a good example of a study where the t test for dependent means can be taken. Same applies in case 3.
2nd degree and in form
ax^2+bx+c
it is a prabola
the minimum cost is the vertex (every parabola has only one, min or max)
minimum cost is the vertex
vertex=-b/(2a)
a=0.4
b=-208
vertex=-(-208)/(2*0.4)
vertex=208/0.8
vertex=260 (means 260 dresses)
that is x value
subsitute for y value
C(x)=0.4(260)^2-208(260)+37365
C(x)=10325
minimum cost is $10,325
