Assume that you only include whole numbers (1,2,3,4,5,6,7,8,9) and not 3.5 and such
so if 1 is odd and less than 5 then it is
1 or 3, since 5 isn't included
then the other number, to be less than 5 when added,
must be
1+x<5
3+x<5
solve each
1+x<5
subtract 1
x<4
set of answers are 1,2,3
3+x<5
subtract 3
x<2
set of answer is 1
so the possible numbers are
1,2,3
that is 3 numbesr out of 9 so
probability=(total desired outcomes)/(total possible outcomes) so
disred outcomes=3
total possible=9
3/9=1/3
the probabiltiy is 1/3
Okay lets get started.
I drove 110 miles with speed of 55 mi/hr so the time taken =
time = distance / speed
time = 110 / 55 = 2 hrs For the distance which is covered with 55 mi/hr speed.
Total time for reaching home is 4 hrs 15 minutes. (given in question)
Means rest distance after snow is covered in = 4 hrs 15 minutes - 2 hrs
= 2 hrs 15 minutes = 2 + 15/60 = 2.25 hrs
The speed in snow driving is 35 mi/hr
So distance covered in snow driving is = 2.25 * 35 = 78.75 miles
Hence the total distance = 110 + 78.75 = 188.75 miles : Answer
Hope that will help :)
Independent variables (IV): These are the factors or conditions that you manipulate in an experiment.
Dependent variable It is something that depends on other factors
A constant is a value or number that never changes in expression; it's constantly the same.
A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results.
I hope I was helpful
23. it increased by 12 because the difference between -4 and 8 is 12
24. 25 because 40 minus 15 is 25
26. 5 because 156 minus 96 equals 60 and 60 divided by 12 equals 5
1/2. You would round 3/8 to 1/2 to 0. Then you add 1/2 to 0 and you get your answer.
