Answer:
B. The width of the confidence interval would be smaller.
Step-by-step explanation:
By reducing the confidence level from 99% to 95%, the student assumes that there is more uncertainty about the new confidence interval than the previous one. That, being said, since the results aren't as certain, the confidence interval is widened towards a central average point because the new interval isn't as accurate.
Therefore, the answer is B. The width of the confidence interval would be smaller.
N + (n+1) + (n+2) = -369
3n + 3 = -369
3n = -366
n = -122
so the three consecutive integers are : -124 ; -123 ; -122
After factoring
the solutions are x=0 , x=3, x= -3
Step-by-step explanation:
We need to solve by factoring:

Solving:

Taking 3x common:

Now using formula 


So, After factoring
the solutions are x=0 , x=3, x= -3

Answer:

Step-by-step explanation:
This is simple, the picture that is provided tells us the answer easily.
An angle lower than 90 degrees is called an acute angle. While one that is the same as 90 degrees is a right angle, and one that is more than 90 is obtuse.
We are asked to take a look at angle 4, we can see that is more than 90 degrees. Since 100 is the only answer with an amount higher than 90 degrees and fits the angle, it is the angle.
The domain of the function is [-4,∞).
Domain is the set of all the possible inputs for which the function is defined.
The given function is:
y = √x+4
It is a radical function. The function is defined if the expression inside the radical greater than or equal to zero.
x+4≥0
Subtract 4 from both the sides.
x+4-4 ≥ 0-4
x ≥ 4
The domain of the function is:
Domain = {xIx ≥ -4} = [-4,∞)
