Answer:
(2, - 5)
Step-by-step explanation:
The line y = -1 is horizontal: parallel to the y-axis.
The point B (2,3) is above the line y = - 1 at a distance equal to the y-coordinate of B (y = 3) less - 1:
Δy = 3 - ( - 1) = 4
When the point B (2,3) is reflected over the line y = -1, the x-coordinate does not change. The image will be 4 units down the line y = -1, thus the y-coordinate will be - 1 - 4 = - 5.
Hence, the coordinates of the vertex B' are x = 2, y = - 5: (2, - 5).

What are the solutions of 3x2 - x + 7 = 0?
Answer:
x =(1-√-83)/6=(1-i√ 83 )/6= 0.1667-1.5184
x =(1+√-83)/6=(1+i√ 83 )/6= 0.1667+1.5184
Step-by-step explanation:
3x2-x+7=0
Two solutions were found :
x =(1-√-83)/6=(1-i√ 83 )/6= 0.1667-1.5184i
x =(1+√-83)/6=(1+i√ 83 )/6= 0.1667+1.5184i

Josh draws a card randomly from a deck, records the suit, returns the card to the deck, and then shuffles the deck. He performs 500 trials. Explain how to use the probability model to predict how many times Josh can expect to draw a card that is a spade.
Answer:
125
Step-by-step explanation:
The probability of getting a spade is 14/56. We multiply 14/56 times 500 that equals 125. I think Josh will get a spade 125 times out of 500.

What I want you to do is think of yourself as a tourist who just landed in Nebraska. You've decided to take a road trip across the northwestern US (as presented in the states shown on the map) and you want to cross each state border exactly once. So for example, you want to make sure that you cross the border between SD-ND, SD-NE, SD-WY, SD-MT. You don't just want to visit South Dakota, but you want to cross all of the borders as well... but only once! You can visit each state as many times as you wish, but you can only cross each border once. Can you think of a way to cross ALL of the state borders in the map exactly once, while ending back where you started in Nebraska?

If the linear model applies the function f(x) = 1.3x + 9.2, what is the predicted value and residual
when the tree is 3 years old with a height of 14?
A) Predicted value: 13.1
Residual: 0.9
B) Predicted value: 11.8 Residual: 0.2
C) Predicted value: 15.7 Residual: 1.3
D) Predicted value: 18.3 Residual: 0.7
Answer:
A) Predicted value: 13.1 Residual: 0.9
Step-by-step explanation:
By definition:
residual = observed - predicted
The linear model is:
f(x) = 1.3x + 9.2
where f(x) is the height and x is the age of the tree.
Replacing with x = 3:
f(x) = 1.3(3) + 9.2 = 13.1 ft
which is the predicted value. The observed value is 14 ft, then:
residual = 14 - 13.1 = 0.9 ft
