You and your 8 friends decide to draw straws for a prize. There are 8 long straws and 1 short straw. Describe how the theoretical probability of drawing the short straw changes as each friend picks a straw.
Answers
Answer:
the total of straw are going to be 9 and there will be a 1/9 chances of getting the short straw. while each friend picks a straw the probability of getting a short straw is going to be higher because the amount of straws are going to be lessened.

3(x - 6) = -15 + 3x
Yes no solution show work
Answers
Answer:
see explanation
Step-by-step explanation:
Given
3(x - 6) = - 15 + 3x ← distribute parenthesis on left side
3x - 18 = - 15 + 3x ( add 18 to both sides )
3x = 3 + 3x ( subtract 3x from both sides )
0 = 3 ← not possible
This indicates the equation has no solution

1.Write the equation in point-slope form with the given slope of -2 and passes through the point (4,-5)
2. Write the equation in slope-intercept form of the line parallel to y=4x-2 and passes through (4,6)
3. Write the equation in slope-intercept form with the given slope of 3 and passes through (-1,1)
4. Write the equation in slope-intercept form of the line perpendicular to 2x-7y=1 and passes through (0,-4)
Answers
The equation in point-slope form: y - y₁ = m(x - x₁)
slope: m = -2
point: (4, -5) ⇒ x₁ = 4, y₁ = -5
Therefore, the equation of the line in point-slope form:
y + 5 = -2(x - 4)2.The equation in slope-intercept form: y = mx + b
Parallel lines has the same slope, so:
y = 4x + 2 ⇒ a = 4
If a line passes through the point (x₁, y₁) then the equation y₁ = mx₁ + b is true.
(4, 6) ⇒ x₁ = 4, y₁ = 6
So: 6 = 4·4 + b ⇒ b = -10
Therefore the equation:
y = 4x - 103.a = 3
(-1, 1) ⇒ x₁ = -1, y₁ = 1
So: 1 = 3·(-1) + b ⇒ b = 4
The equation:
y = 3x + 44.The product of slopes of perpendicular lines is -1.
2x - 7y = 1 ⇒ 7y = -2x + 1 ⇒ y = -²/₇x + ¹/₇
-²/₇×m = -1 ⇒ m = ⁷/₂
(0, -4) ⇒ x₁ = 0, y₁ = -4
-4 = ⁷/₂·0 + b ⇒ b = -4
The equation:
y = ⁷/₂x - 4Using the graph below, find A, H, and K.

Answer:
B
Step-by-step explanation:
For this problem, you would only need to figure one of them out since all the numbers vary. I calculated the mean. Mean is the same as the average. First, add all the numbers up. I got 112. Then, divide 112 by the amount of numbers you added (8). 112/8 is 14, and the mean=14 is b.
A is the point with coordinates (4, 6)
B is the point with coordinates (d, 21)

Jane's cell phone plan is $58 each month plus $0.20 per minute for each minute over 200 minutes of call time. Jane's cell phone bill last month was $67.00. Write an equation that can be used to determine the number of minutes over 200 that Jane was billed. How many minutes over 200 was Jane billed last month?
Answers
Answer: 45 minutes more than 200
Step-by-step explanation:
So for every minute over 200 jane has to pay 0.20 cents per additional minute. The equation we can use is $58+0.20m=$67 where m is the amount of minutes after 200 jane has to pay 20 cents per
58+0.20m=67
0.20m=9
m=45
So Jane was billed for 45 minutes over 200 minutes last month. so in total 245 minutes and she was charged for the extra 45 minutes
