Answer:
The interval is 
Step-by-step explanation:
From the question we are told that
The sample size is 
The population proportion is 
The confidence level is C = 98%
The level of significance is mathematically evaluated as
%

Here this level of significance represented the left and the right tail
The degree of freedom is evaluated as

substituting value


Since we require the critical value of one tail in order to evaluate the 98% confidence interval that estimates the proportion of them that are involved in an after school activity. we will divide the level of significance by 2
The critical value of
and the evaluated degree of freedom is

this is obtained from the critical value table
The standard error is mathematically evaluated as
substituting value
The 98% confidence interval is evaluated as

substituting value


Answer:
b.) 9/g = 28.5
Step-by-step explanation:
a.) 9g = 28.5
b.) 9/g = 28.5
c.) 28.5 = 9 x g
d.) 28.5/9 = g
Total billing = $28.50
Rate = $9 per gigabyte
Calculate the additional gigabytes, g, that you used.
Additional gigabyte used, g = Total billing / Rate
g = $28.50 / $9
9g = 28.50
28.50 = 9 × g
g = 28.50 / 9
Option b.) 9/g = 28.5 is the incorrect way to calculate the additional gigabytes, g, that you used.
A function cannot have symmetry with respect to the x-axis
Answer:
x and y do not have a proportional relationship. The constant would be 1.7
Step-by-step explanation:
The reason for this is because as the miles increase they are not following a straight pattern. While 14+14=28 and 28+14=42, 42+14 doesn't equal 70. Even if you think about it in a sense of multiplication, while 14x2=28, 28x2 does not equal 42. What should be done is that the opposite factor of each number should be added together and divided by 3. So 28/14=2, 42/28=1.5, and 70/42=1.6. Then you should take the numbers 2, 1.5, and 1.6, add them together and divide by 3. The answer that you should recieve is 1.7.
Hope that helped.
