Answer:
y=2/3x
Step-by-step explanation:
A direct variation equation is y=kx. if k=2/3, then if x was 9,y would be 6.
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:
Length of prism = 17.5 in
Step-by-step explanation:
Given:
Width = 16 in
Height = = 3.75 in
Volume of rectangular prism = 1,050 inches
Find:
Length of prism
Computation:
Volume of rectangular prism = WHL
1,050 = Length of prism × 16 × 3.75
Length of prism = 17.5 in
Answer:
correct. the mean of 72 and 89 is 80?5
Step-by-step explanation:
find the mean to confirm it.
(a+b)/2
72+89= 161
161/2=80.5
