so y=5x on a graph is going to look like a 5/1 slope. X represents days and Y represents miles. So (1,5) means in 1 day Fran runs 5 miles.
Answer:
-2 (2 x^2 - 2 x + 5)
Step-by-step explanation:
Factor the following:
-4 x^2 + 4 x - 10
Factor -2 out of -4 x^2 + 4 x - 10:
Answer: -2 (2 x^2 - 2 x + 5)
Answer:
-5
Step-by-step explanation:
-15<-6=-15
-15÷3
=-5
Margin of error = +/- Z*SD/sqrt (n)
Where, Z = 1.96 at 95% confidence interval, SD =standard deviation = 589 dollars, n= sample size (to be calculated)
For the values given;
132= 1.96*589/Sqrt (n) => Sqrt (n) = 1.96*589/132 = 8.7458 => n= 8.7458^2 = 76.49
Rounding up to near a person, n (sample size)= 77 students
Answer:
2/3 +9.26 = 0.6666+9.26=rational
