Two lines, C and D, are represented by the following equations: Line C: y = x + 5 Line D: y = −2x − 1 Which of the following options shows the solution to the system of equations and explains why? (−2, 3), because the point does not lie on any axis (−2, 3), because both lines pass through this point (−2, 3), because one of the lines passes through this point (−2, 3), because the point lies between the two axes

Sarah is rolling a number cube, numbered 1-6, and recording the number that shows up on each roll.Event A describes the probability of getting a 4 on the first roll.Event B describes the probability of getting a 4 on the second roll.Which statement correctly explains whether the events A and B are dependent or independent?Question 1 options:A. A and B are dependent events, because the probability of the first roll will affect the probability of the second roll.B. A and B are independent events, because the probability of the first roll will affect the probability of the second roll.C. A and B are independent events, because the probability of the first roll will not affect the probability of the second roll.D. A and B are dependent events, because the probability of the first roll will not affect the probability of the second roll.

When the light turns yellow, should you stop or go through it? An article defines the “indecision zone” as the period when a vehicle is between 2.5 and 5.5 seconds away from an intersection. At the intersection of Route 7 and North Shrewsbury in Clarendon, Vermont, 154 vehicles were observed to encounter a yellow light in the indecision zone, and 20 of them ran the red light. At the intersection of Route 62 and Paine Turnpike in Berlin, Vermont, 183 vehicles entered the intersection in the indecision zone, and 20 ran the red light. Can you conclude that the proportion of red-light runners differs between the two intersections? Find the P-value and state a conclusion. Round the answer to four decimal places.

The manufacturer of the X-15 steel-belted radial truck tire claims that the mean mileage thetire can be driven before the tread wears out is 60,000 miles. The standard deviation of themileage is 5,000 miles. Viking Truck Company bought 48 tires and found that the meanmileage for their trucks is 59,500 miles. Is Viking's experience different from that claimed bythe manufacturer at the 0.05 significance level?(a) State the null hypothesis and the alternative hypothesis. (b) State the decision rule.(b) Compute the value of the test statistic. (d) What is your decision regarding H0 ?(e) What is the p-value? Interpret it.

Crystal is amazed! She graphed ΔABC using the points A(5, –1), B(3, –7), and C(6, –2). Then she rotated ΔABC 90° counterclockwise (↺) about the origin to find ΔA′B′C′. Meanwhile, her teammate took a different triangle (ΔTUV) and rotated it 90° clockwise (↻) about the origin to find ΔT′U′V′. Amazingly, ΔA′B′C′ and ΔT′U′V′ ended up having exactly the same points! Name the coordinates of the vertices of ΔTUV.
