Answers
Answer:
B. They will have the same slopes but different y-intercepts.Step-by-step explanation:
MelanieThe slope:
m = (59 - 48)/(2013 - 2010) = 11/3The y -intercept:
the starting point, 2010The equation off the line:
y = 11/3x + 2010TracyThe slope:
m = (59 - 48)/(3 - 0) = 11/3The y -intercept:
the starting point, 0The equation off the line:
y = 11/3xAs we see they get same slopes but different y-intercepts.
Correct choice is B

4. A''(-3, 13)
5. No
Step-by-step explanation:
2. The translation is represented by the transformation ...
(x, y) ⇒ (x-4, y+8)
A(7, 5) ⇒ A'(7-4, 5+8) = A'(3, 13)
__
4. The reflection is represented by the transformation ...
(x, y) ⇒ (-x, y)
A'(3, 13) ⇒ A''(-3, 13)

Area of sector of a circle = 28.26 meter²
Step-by-step explanation:
Given:
Side of cube = 12 meter
One white section = sector of a circle
Find:
Area of one white section
Computation:
Radius of circle = Side of cube / 2
Radius of circle = 12 / 2
Radius of circle = 6 meter
One white section = sector of a circle
Area of sector of a circle = [θ/360][π][r]²
Area of sector of a circle = [90/360][22/7][6]²
Area of sector of a circle = [0.25][3.14][36]
Area of sector of a circle = 28.26 meter²

Luca decides to play Wheel of Letter. To play the game, contestants spin a wheel with 26 equal sections, letter A through Z. If the pointer lands on any letter in the phrase “COUNTRY PHRASE,” the contestant wins a prize.
What is the probability that Luca will win Wheel of Letters?
Answers
The probability that Luca will win Wheel of Letters for this considered case is 6/13
How to calculate the probability of an event?Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.
Then, suppose we want to find the probability of an event E.
Then, its probability is given as
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}}[/tex]
where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.
For this case, the sample space of result of wheel of letters spin is
S = {A, B, ..., Z} , thus, n(S) = size of S = 26
Let E = event that the spinner will stop in one of the letters in “COUNTRY PHRASE”
Then, the outcomes in favor of E are {'P', 'O', 'C', 'A', 'T', 'R', 'Y', 'N', 'H', 'S', 'U', 'E'}
Thus, n(Favorable cases for E) = 12 (counted unique ones, and not repeated), as each letter is only 1 time in the spinner.
Thus, we get:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{12}{26} =\dfrac{6}{13}[/tex]
Thus, the probability that Luca will win Wheel of Letters for this considered case is 6/13
