Answer:
b. 98
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find M as such
In which 
is the standard deviation of the population and n is the size of the sample.
In this problem, we have that:
So a sample of at least 98 is required.
The correct answer is:
b. 98
The answer is 1.b 2. d 3. c 4. c
Answer:
The new function is g(x) = -x + 4
Step-by-step explanation:
- If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k
- If the function f(x) reflected across the y-axis, then its image is g(x) = f(-x)
∵ A function f(x) = x
∵ It is vertically translated 4 units up
→ By using the 1st rule above, the value of k = 4
∴ k = 4
∵ Its image h(x) = f(x) + k
∴ Its image h(x) = f(x) + 4
∴ Its image h(x) = x + 4
∵ Then it is reflected across the y-axis
→ By using the 2nd rule above, change the sign of x in h(x)
∵ h(x) = x + 4
∴ g(x) = h(-x)
∴ g(x) = -x + 4
∴ The new function is g(x) = -x + 4
Answer4/8 x 69
Step-by-step explanation:
You add Tekashi
Answer:
No
Step-by-step explanation:
you have to subtract 2x from 3x, so you have just x( you don't need the one in front of it)
So the answer would be ( x-4)
Hope that this helps you and have a great day :)
