Answer:
C. becomes narrower
Step-by-step explanation:
If the confidence level is reduced from 95% to 90%, then, the confidence interval for u becomes narrower, i.e., we are less sure that the true value of u is contained inside the new interval. With a 95% confidence interval there is a probability of 0.95 that the parameter u is inside the interval and with a 90% confidence interval there is a probability of 0.90 that the parameter u is inside the interval.
Answer:
x = 6
Step-by-step explanation:
Step 1 - Expand brackets via distributive property:
Step 2 - Combine like terms:
Step 3 - Use the addition property of equality to isolate the 9x:
Step 4 - Use the subtraction property of equality to move the 5x over and isolate the 24:
Step 5 - Use the division property of equality to simplify:
Hope this helps!
9r=108
To solve for r, we must isolate it. To do this, divide both sides by 9.
r=108/9
Simplified, r=9
Answer:
Step-by-step explanation:
The given function is
If a function translated vertically upward by p units, then we need to add p in the function value to get the new function.
It is given that if the graph of h is translated vertically upward by 4 units, it becomes the graph of a function g. So,
On simplification, we get
Therefore, the required function is .
