the slope is the five
Step-by-step explanation:
Answer:
4.75 hours
Step-by-step explanation:
First you need to find the median of the two numbers. The fastest way to do it is to add 9.3 and 9.7 and divide by 2, which will give you 9.5. Since there's going to be two of them working, divide 9.5 by 2, and you get 4.75.
I believe the answer is 0. Hope this helps.
80% of what is 56
0.80x = 56
x = 56/0.80
x = 70
check..
80% of 70 is 56
.80(70) = 56
56 = 56 (correct)
so there were 70 items on the test
Divide both sides by 2
|x-3|>4 and |x-3|<-4
ok so |x-3|<-4 is false, since |x|≥0 always
so we have
|x-3|>4
now assume
x-3>4 and
x-3<-4
x-3>
add 3
x>7
x-3<-4
add 3
x<-1
so
-1>x and x>7
so basically it is all numbers from -∞ to +∞ except from -1 to 7
in interval notaion
(-∞,-1)U(7,∞)
S={x|x<-1 or x>7}
