the answer is 30.5
Answer:
Step-by-step explanation:
324mi/4.5in=72mi/in
So each inch is equal to 72 miles.
40 out of 250 students speak French: 40 / 250 = 0.16
Multiply the number of students surveyed by 0.16:
30 x 0.16 = 4.8
Round up to 5 students.
Answer 5 students
Answer:
![\bold{m=-\dfrac25}](https://tex.z-dn.net/?f=%5Cbold%7Bm%3D-%5Cdfrac25%7D)
Step-by-step explanation:
![\bold{slope\, (m)=\dfrac{change\ in\ Y}{change\ in\ X}=\dfrac{y_2-y_1}{x_2-x_1}}](https://tex.z-dn.net/?f=%5Cbold%7Bslope%5C%2C%20%28m%29%3D%5Cdfrac%7Bchange%5C%20in%5C%20Y%7D%7Bchange%5C%20in%5C%20X%7D%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%7D)
(-5, 7) ⇒ x₁ = -5, y₁ = 7
(10, 1) ⇒ x₂ = 10, y₂ = 1
So the slope:
![\bold{m=\dfrac{1-7}{10+5}=\dfrac{-6}{15}=-\dfrac25}](https://tex.z-dn.net/?f=%5Cbold%7Bm%3D%5Cdfrac%7B1-7%7D%7B10%2B5%7D%3D%5Cdfrac%7B-6%7D%7B15%7D%3D-%5Cdfrac25%7D)
