68% you have to divide 17 by 25 and then move the decimal
Answer:
2/3=0.6667
Step-by-step explanation:
Let X be the cycle time for trucks hauling concrete to a highway construction site
Given that X is U(50,70)
Hence pdf of X is
Let A be the event that cycle time is no more than 65 minutes and
B the event cycle time exceeds 55 minutes
Required probability
= the conditional probability that the cycle time is no more than 65 minutes if it is known that the cycle time exceeds 55 minutes
= P(A/B)
=
Step-by-step explanation:
let us start with
Molly's equation
15x + 10 = 100
solving for x we have
15x=100-10
15x=90
x=90/15
x=6
Maddie's equation
15x - 10 = 100
solving for x we have
15x=100+10
15x=120
x=120/15
x=8
well, from the solution niether of them is correct
Fractions and decimals are related in a very close way. Ways such as they are both representing a whole number.
for example
1/2 , 0.5 , 50%
all three numbers have the same value but are expressed in a different format. all three represent the same whole number.
another example would be
1/4 , 0.25 , 25%
hopefully this helped. and or makes sense.
LET ME KNOW :p
