Answer:
2
Step-by-step explanation:
Remember the rule with negatives. -x/-y=x/y
So -6/-3=6/3
6/3=2
Answer:
360 students
Step-by-step explanation:
We start off with 368.
Then 72 leave the school, so subtract 72 from our total.
368 - 72 = 296
But, then 64 new students join, so add this to our new total.
296 + 64 = 360.

Answer:
28 polio vaccinations and 32 measles vacinnacions.
Step-by-step explanation:
x= polio vaccinations
y= measles vaccinations
here we have an ecuation system:
x+y=60 (vaccinations)
2x+4y=184 (doses)
In order to solve it I will solve the x in the first ecuation:
x=60-y
And replace it on the other ecuation:
2(60-y)+4y=184 -----> 120-2y+4y=184------>2y=64------->y=32
Now I replace this result in x=60-y, so x=28.
Answer:
a) 0.92; b) 84%
Step-by-step explanation:
First we enter the data into a graphing calculator. Use the values for X, The number of tourists, in the first list and the values for Y, the number of riders, in the second list.
Bring up the scatter plot and then run the linear regression. We get the equation
y = 1.59x + 5.06.
For part a,
The correlation coefficient, r, is 0.92. This means the equation is a good fit for the data.
For part b,
The coefficient of determination, r², tells us what percentage of variation in the dependent variable, y, is explained by the independent variable, x. This value is 0.84, which is 84%.
