These are the y intercepts
1. (0, 1/3)
2. (0, 26/3)
Answer:
The answer to the equation is W’(4, –2), X’(3, –4), Y’(1, –4), Z’(0, –2)
Step-by-step explanation:
Because its turning 180 degrees that means its turning half the way it is. and if you look on the graph the z is Z (0, 2). which if you flip it upside down it would be (0,-2)
Also i took the test! :)
Usually, the function of a parabola is y=ax^2+bx+c. With your three given points, which I don't know, plug in your x's and y's to come up with three quadratic equations. Using those equations, you use algebra to find out what a, b, and c equal. Once you have a numerical answer, insert them in the usual quadratic function to have your answer.

Answer:
0.05155 or 5.155%
Step-by-step explanation:
We are given;
Weight of passenger cars the ferry can accommodate = 79 tons of passenger cars
Number of cars loaded = 39
Thus;
population mean weight; μ = 1.9
Since it can accommodate 79 tons of passenger cars, then their average weight should not exceed;
79/39 = 2.03 thus;
Sample mean; x¯ = 2.03
Standard deviation; σ = 0.5
Sample size; n = 39
Let's find the z-score value;
z = (x¯ - μ)/(σ/√n)
Thus;
z = (2.03 - 1.9)/(0.5/√39)
z = 0.13/0.08
z ≈ 1.63
Thus; P(z > 1.63) = 1 - P(z < 1.63)
From the z-score table attached, the p-value which is the probability is P(z < 1.63)
Thus;
P = 1 - 0.94845
P = 0.05155 or 5.155%
