Answer:
B.It takes more than 12 loads to wash 9 bins of towels.
Step-by-step explanation:
The function f(x) gives the number of loads required when there are x bins of towels to be washed.
f(x)=Number of loads
x=Bins of towels
Therefore in the inequality f(9)>12
- Number of loads=12
- Bins of towel =9
If f(9)>12, it means Number of loads is more than 12.
f(9)>12 therefore tells us that it takes more than 12 loads to wash 9 bins of towels.
The correct option is B
Answer:
A.48.99
48.992 two is less than five soo you leave it at that point and assume the 2.

Answer:
And rounded up we have that n=421
Step-by-step explanation:
We know that the sample proportion have the following distribution:

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 90% of confidence, our significance level would be given by
and
. And the critical value would be given by:
The margin of error for the proportion interval is given by this formula:
(a)
And on this case we have that
and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
We assume that a prior estimation for p would be
since we don't have any other info provided. And replacing into equation (b) the values from part a we got:
And rounded up we have that n=421
Answer:
mABC = 81°
mCAB = 59°
Let’s start with finding mCAB.
Segment CD is a straight line that runs through A, so we know it is a total of 180°.
The problem tells us that there is a right angle (90°) and gives us that 31° in between. Since they all have to add up to 180, we can do
180 - 90 - 31 = ...59°!
Now that we have mCAB, we can find mABC.
All the angles in any triangle must add up to 180. Since we now know mCAB (59°) and mCBA (40°), we can subtract to find the missing angle.
180 - 59 - 40 = ...81°!
Hope this helps! Brainliest always appreciated
