Answer: 111 dollars
Step-by-step explanation:
7 hours on Saturday and 4 hours on Sunday
Sunday gets paid 1 1/3, or 4/3 times more which is 9 x 4/3 = 12 per hour
Saturday is 9 per hour
7x9 (Saturday) + 4x12 (Sunday) = 111 dollars
Answer:
0.2983
Step-by-step explanation:
Let X be the reading on thermometer. Given that X is N(0,1)
We are to find the probability that a randomly selected thermometer reads between negative 0.12 and 1.02
Reqd probability = .
Since this x is already normal std variable x=z
i.e. reqd prob =
Hence answer is 0.2983
Step-by-step explanation:
A) Let X= the number of weeks 46 times 3/4 = 72. And 135+72 x >_ 580
B) 135+72 x >_ 580. 580-135. 72/72 >_ 445/72
x >_ 6.2
She must work a minimun of 7 weeks to get $580.
Answer:
Let the speed of the train be x km/hr and the speed of the bus is y km/hr.
So according to question and using
Total distance =300 km
Mansi travels 60 km by train and 300−60=240 by bus in 4 minute,
and 100 km by train, 300−100=200 by bus, and takes 10 minutes more,
Now, let
and.
multiply (1) by 5 and (2) by 6 we get
Subtracting (3) and (4) we get
Putting the value of a in (1) we get
Now ,
Hence, the speed of the train is 60 km/hr and the speed of the bus is 80 km/hr.
