Answer:

And we can use the normal table and the complement rule we got:

Step-by-step explanation:
For this case we have the following parameters given:

We select a ample size of n=49. And we want to find this probability:

And for this case is a right tail probability and we can use the z score formula given by:

And replacing we got:

And we can use the normal table and the complement rule we got:

Answer:
Answer down below!
Step-by-step explanation:
1) 10
2) 4
3) 6
----------------
1 ) we know that perimeter = all the sides combined.
- (44 is the given perim.; so therefore if 12x2+10x2=44, 20 is the missing width.
2 ) we know that area = lw.
- 44 is the given area, so therefore if 10x4=40, 4 is the base.
3 ) we know that area = lw.
we need to find the area of the square. 3 x 2 = 6. 6 is the area of the missing square or the part that needs to be covered.
Greater than because 5 feet equal 60 inches
Answer:
14.4%
Step-by-step explanation:
Of the 39% who fail the first exam, 37% fail a second time. Those are the ones who take it 3 times:
