Answer:
No, You can't. You have to make their denominators equal!

Step-by-step explanation:
So first, you make their denominators equal!

Multiplying both the numerator and denominator with the same number results in the same fraction, just un-simplified
So, we input it!

There you go!
Hope you get better at math!(gets wayyyyyyyyyyy...y more complicated later)
Hope this helps!
See Ya!

part b: 30/60=1/2
Answer:
Third option given
Step-by-step explanation:
On a coordinate plane, a parabola opens to the right with a vertex at (0, 0).
use the following x values to plot the associated y values on the x-y plane:
If x = 0, then 
If x = 1, then 
If x = 4, then 
If x = 9, then 
Join the points and you will find a branch of a parabola opening to the right.
Answer:
The probability of rolling a number that is even and a multiple of 3 is 
Step-by-step explanation:
The total possible outcomes of cube = { 1, 2, 3 , 4 , 5 , 6}
Now, let E: Event of getting an even number and a multiple of 3
So, out of all the outcomes, {6) is the ONLY possible favorable outcome.

or, 
Hence, the probability of rolling a number that is even and a multiple of 3 is 
Answer:
a. The expected or average costs for all weekly rat purchases is $20.00
Step-by-step explanation:
a. A mean value of $20.00 means that over a period of 52 weeks, the company can expect to spend $20.00 per week on rat purchases.
b. This is incorrect since individual values don't interfere in the mean. For instance, if half the weeks had a cost of $19.00 and the other half had a cost of $21.00, the mean cost would still be $20.00 even though no particular week had a $20.00 cost
c. Incorrect. The median is the central value in a distribution; the median and the mean are not necessarily the same.
d. Incorrect, same as item b.
