So 52 words per 1 minute
364 words per x minute
52:1 as is 364:x so
divide 364 by 52 and get 7
she typed 7 minutes
so 40% means 40/100 or 4/10
so 364=4/10
divide 364 by 2
364/2=182=2/10
multiply 182 by 5 ( to make 2/10 into 10/10) and get 910=words total to type
BUT WE WANT TO FIND WORDS LEFT so
910-364=546
she has 546 words left to type
Answer:
P(x < 5) = 0.70
Step-by-step explanation:
Note: The area under a probability "curve" must be = to 1.
Finding the sub-area representing x < 5 immediately yields the desired probability.
Draw a dashed, vertical line through x = 5. The resulting area, on the left, is a trapezoid. The area of a trapezoid is equal to:
(average length)·(width, which here is:
2 + 5
----------- · 0.02 = (7/2)(0.2) = 0.70
2
Thus, P(x < 5) = 0.70
