28/2 or 28 x (1/2)
You can either divide $28 by 2 or multiply it by (1/2)
Hi!
Let's make a small chart
18:15 left town B
19:15 1 hour
20:15 2 hours
21:15 3 hours
Since they actually arrived at 21:05, and not 21:15, we know it took more than 2 hours, but less than 3 hours.
Subtract the extra time
21:15-21:05 = 00:10
Since there are 60 minutes in an hour, (60-10=50) we know it took 2 hours and 50 minutes.
Another way to solve this would be to convert the times to decimals, and subtract,
21.05-18.15 = 2.9
Then convert the decimal to the time.
9/10 of an hour = 50 minutes
It took 2 hours and 50 minutes
Hope this helps! :)
2 divided into 7 gives 3 with remainder 1
so as a mixed number 7/2 = 3 1/2
Answer:
Option D) 50
Step-by-step explanation:
We are given the following information in the question:
p = 0.5
Sample size,n = 100
We have to find the expected value of the distribution.
Formula:
Putting the values, we get,
The expected value of this distribution is 50.
The slope of a line in form ax+by=c is -a/b
the yint of the line is c/b
so
-6x-5y=15
slope=-(-6)/-5=6/-5=-6/5
yint is 15/-5=-15/5=-3
slope=-6/5
yint is -3
or you could just do slope intercept and solve for y
y=mx+b
m=slope
b=yintercept
slope=-6/5
yint is -3
