Answer:
88 times
Step-by-step explanation:
The two comes up 20 out of 50 times
We don't know how many times 2 will come up if the die is rolled 220 times. We can, however, set up a proportion
20/50 = x/220 Cross multiply
50x = 20 * 220 Combine the right
50x = 4400 Divide by 50
50x/50 = 4400/50 Do the division
x = 88 times.
in the equation as we can say x= 2y-10.
so, substitute x=2y-10 everywhere then the x in 1240 gets cancelled with 2y-10 then solve the remaining you will get 4y-20+3y=1240
7y=1260
y=1260/7
y=180
then substitute the value of y everywhere
2x+3y=1240
2x+3(180)=1240
2x=1240-540
2x=700
x=350
DONE.
8\9 is the correct answer becuase 5 plus 3 is 8 so 8\9

Answer:
Consider the following explanation
Step-by-step explanation:
The experimental unit here is a cat.
The explanatory variable is a numerical variable which identifies the time for which a given cat is subjected to hunger deprivation.
The response variable is a categorical variable which identifies whether there is an increase in aggression in a given cat.
The interacting variable is a numerical variable where weight of a given cat is noted.
Population here is the 10 cats.
There is no control group for the given experiment.
Dependent variable is the weight of each cat as it changes as the experimental units are subjected to hunger deprivation.
