Answer:
b. 224
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 the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
In this problem:
We want to find n, when 
So
The nearest integer number to 223.9 is 224.
So the correct answer is:
b. 224
Hello there,
The equation that is give to us is as follows:
- -1 = 5 +
In order to solve for x we would first subtract 5 from both sides and then multiply by 6:
This means that x would equal to -1 given the equation above.
Hope I helped,
Amna
I’m not 100% sure but I think it’s D.
Answer:
Hey!
The 6th term of your sequence is 23!
Step-by-step explanation:
<u>This is how you get it...</u>
1) T6=3n+5 (the 6th term and the equation...)
2. We now do T6=3(6)+5 (3 x 6 then add 5)
3. In other words... T6=18+5
4. We work it out 18 + 5 = 23
HOPE THIS HELPS!!

Answer:
The slope would be -5/12 and the intercept would be -11/12
Step-by-step explanation:
To find the slope and intercept of this line, solve for y.
-5x - 12y = 11
-12y = 5x + 11
y = -5/12x - 11/12
Now that we have this, we know that the slope is the coefficient of x (-5/12). Then we can locate the intercept as the constant at the end (-11/12)
