Answer:
36.12
Step-by-step explanation:
43% of 84 can be rewritten to 43% * 84 or 43/100 * 84.
43/100 * 84/1 = 3612/100
3612/100 = 36.12
5/7 which means for every 7 kids, one owns a dog
Answer:
Answer: (7,-2)
Step-by-step explanation:
Look at the formula
1) (x – h)^2 + (y – k)^2 = r2
the center is described by (h,k)
now look at
(x – 7)^2 + (y +2)^2 = 25
here h=7
but k= -2 because is (y+2) =(y-(-2))
Answer:
B. Yes, there is reason. The TV audience might not be representative of the population.
Step-by-step explanation:
The question "Do you support new national mileage standards forautomobiles?" is asked to the TV audience.
Therefore those who will voted are the ones who are watching the TV show. We do not know the rate of people who do not watch TV or who do not watch that TV talk show in the population.
Thus the results cannot represent the whole population
Answer : Option A
Explanation:
we can clearly see that from x+ y=5 we can substitute y = 5-x in y = 9x^2
Option B is clearly incorrect x can not be y -5
Option C is incorrect because y can not be 5 +x
Option D is incorrect because its y = 9x^2 not y^2 =9x^2 so y can not be 3x
if its y^2 = 9x^2 then only implies y = 3x
