Answer: 4
Step-by-step explanation:
Perpendicular lines have reciprocal slopes
Answer:
A
Step-by-step explanation:
A function have the inverse only if it passes the horizontal line test ,
For the given options we need to look for the function which passes the horizontal line test
Option A is g(x)= 2x-3 which is a straight line with slope not equal to 0 so it passes the horizontal line test and hence it will have an inverse which is also a function.
Option B: we need to restrict the domain to get the inverse so the option B is not correct .
Option C : It also fails the horizontal line test .
Option D : Horizontal line so it also fails the horizontal line test .
Answer:
The requirements for the hypothesis test does satisfied the method for testing the claim that from two population proportions the rate of polio is less for children given the salk vaccine.
Step-by-step explanation:
The percentage of children in the treatment group was:
(201229/401974)*100 = 49.9%
The percentage of children given placebo was:
(200745/401974)*100 = 50.1%
The percentage of children that developed polio in the treatment group:
(33/200745)*100 = 0.0164%
The percentage of children that developed polio in the placebo group:
(115/201229)*100 = 0.0571%
The percentage difference between the two group:
((0.0571-0.0164)/0.0571) = 61.62%
Therefore:
The amount of children used for each group was almost divided into half of the total amount of children. The test revealed although very small percentages of the both group developed polio, 68.62% more children given placebo than the children that was given the salk vaccine. Therefore, the study shows that the rate of polio is less for children given the salk vaccine and the the hypthesis test is satisfied.
Answer:
I think it's a because when if the graph was actually able to pass the y axis before the x axis it would be ( 10, 0) however since it's the x axis coming first and it is negative it is going to be ( 0 , -10 )
