She can make up to 22 bags because you have to add 2.40 and 3.25 together to get 5.65 then divide by .25 to get 22.6 she can make a total of 22 with .6 left over
Answer: y = -2/3(x-3)^2 + 0 or y = -2/3(x-3)^2
Step-by-step explanation:
vertex form is y=a(x-h)^2 + k
here we can see the vertex is (3,0) which is (x,y). Or (h,k) in this case.
so to plug that into vertex form, we now have y=a(x-3)^2 + 0. or just y=a(x-3)^2.
now we need to find "a" which is the leading coefficient. to do that we can plug in the (6,-6) for the x and y parts of the above equation. so we'd have
-6=a(6-3)^2. which goes to -6=a(2)^2 which is -6=4a. divide each side by 4 to get a = -2/3. plug this in for a
the final equation would be y = -2/3(x-3)^2 + 0 or y = -2/3(x-3)^2
Answer:
3884.4 is what percent of 46.8 is 8300
Answer:
A) The proportions of wins is the same for teams wearing suits as for teams wearing jeans
Step-by-step explanation:
Although the question says that they will "test the claim at the 0.05 level that the proportion of win is the same for teams wearing sutis as for the teams wearing the jeans", the claim, that will be expressed in the alternative hypothesis, is that there is a significant difference between the two proportions.
The null hypothesis, the one that this test try to nullify, will state that there is no significant difference between the two proportions. Or, saying the same, that the proportions are equal.
The right answer is A, which states that the two proportions (as this is a test on the difference of proportions) are equal.
It’s a good range of values so you get an accurate line
