Answer:
Hello,
0,4925...
Step-by-step explanation:
A geometric random variable X with parameter p has probability function:
Distance covered in 1 rotation = circumference of the wheel
= 2
r
= 2 x 
x 14
= 2 x 22 x 2
= 88 inches
Distance covered in 10 rotations = 88 x 10 = 880 inches
Therefore, the bike covers 880 inches after 10 rotations.
Answer:
y = -x +4
Step-by-step explanation:
2x+5y = 3y+8
Subtract 3y from each side
2x+5y-3y = 3y-3y+8
2x+2y = 8
Subtract 2x from each side
2x+2y -2x = -2x+8
2y = -2x+8
Divide by 2
2y/2 = -2x/2 +8/2
y = -x +4
Answer:
David has 12 pears.
Step-by-step explanation:
4 + 9 = 13
39 / 13 = 3
3 x 4 = 12
3 x 9 = 27
Answer:
y = 2x - 3
Step-by-step explanation:
Since the equation for the line y = 2x + 5 is already in slope-intercept form (y = mx + b), the slope (m) is 2. A parallel line will have the same slope. Now use point-slope formula to find an equation for the parallel line including point (3,3). Point-slope formula is:
(y – y₁) = m(x – x₁), where m is the slope (2) and (x₁, y₁) is the point the line passes through (3,3).
Therefore:
(y – 3) = 2 (x – 3)
y – 3 = 2x – 6
y – 3 + 3 = 2x – 6 + 3
y = 2x - 3
