A train station employee collects data on 160 incoming trains to the station. He notices that 18 of the 90 incoming trains on li

Elena L [17]

Answer:

Probability of a train on line A arriving on time: 80%

Probability of any train arriving on time: 96%

Step-by-step explanation:

If 18 of the 90 incoming trains on line A arrive late, we have that 90 - 18 = 72 trains of the 90 arrive on time, so the probability of a train on line A arriving on time is:

P(A) = 72/90 = 0.8 = 80%

on line B, we have that 70 - 14 = 56 trains of the 70 arrived in time, so the probability of a train from line B arriving on time is:

P(B) = 56/70 = 0.8 = 80%

To find the probability of any train arriving on time, we can use this formula:

P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = 0.8 + 0.8 - 0.8*0.8

P(A or B) = 1.6 - 0.64 = 0.96 = 96%

What are the solutions to the following system of equations? Select the correct answer below.

polet [3.4K]

      y = x² - 4x + 8
4x + y = 12

   4x + y = 12
4x + (x² - 4x + 8) = 12
x² + 4x - 4x + 8 = 12
       x² + 8 = 12
      - 8 - 8
   x² = 4
      x = ±2
   4x + y = 12
4(2) + y = 12
   8 + y = 12
   - 8 - 8
   y = 4

    4x + y = 12
4(-2) + y = 12
    -8 + y = 12
+ 8    + 8
   y = 20

(x, y) = (2, 4) and (-2, 20)

Lubov Fominskaja [6]

Answer:

Part A: Linear relationship

Part B: Using the dividing method

Slope = -3.325

y-intercept is (0, 88.5)

Step-by-step explanation:

Part A

The is an approximately linear relationship between the temperature of his city and the number of chocolate sold

Part B

The line of best fit can be drawn by

1) Plot the data points on the graph

2) Divide the number of data points into two with a vertical dotted line

3) Mark the center of the data on each side of the dividing central line with an a or x

4) Draw a straight line through the x marks that extends to the plot edges

5) The straight line drawn is the line of best fit

The approximate slope is found from points (0, 90) and (20, 20) using the formula for gradient, m, such that we have;

$m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Where:

y₁ = 88

x₁ = 0

y₂ = 22

x₂ = 20

Therefore;

$The \ slope, \ m =\dfrac{22-88.5}{20-0} = \dfrac{-66.5}{20} =-3.325$

From the graph, the y-intercept is approximately (0, 88.5) while the x intercept is approximately (26.5, 0)
