Step-by-step explanation:
(4/5+3/5)+3.5*5
= 7/5+7/2*5
= 7/5+35/2
= 14/10+175/10
= 189/10
= 18.9
Answer:
27.27cm²
Step-by-step explanation:
∅=125° r=5m
A=∅/360×πr²
A=125/360×3.142×5²
A=27.27cm²
The required equation of a line is y = 9/5 (4x - 12)
Given-
The point from which the line passes through is (3,2)
The slope of the given line m is -4/5.
Equation of the line
The linear equation of a line can be represented by a set of points on a graph using the equation of the line.
The standard form of the line passing through the point x₁, y₁
The slope m is given by,
m = (y - y₁) / (x - x₁)
Put the values of points and slope in the above equation, we get,
-4/5 = (y - 2) / (x - 3)
-4/5(x - 3) = y -2
-4x/5 + 12/5 = y - 2
-1/5 (4x - 12) + 2 = y
y = 9/5 (4x - 12)
The linear equation of a line can be represented by a set of points on a graph using the equation of the line. The following equation depicts a line that crosses (3, 2) and has a slope of -4/5: y = 9/5 (4x - 12)

Answer:
1. Not Independent
2. Independent
3. Not Independent
4. Independent
Step-by-step explanation:
Independent: An event is independent if the outcome of one event doesn't effect the outcome of the other event.
Not independent : An event is Not independent if the outcome of one event effect the outcome of other event.
1. A jar contains twenty coins. Two coins are picked randomly without replacement.
Not Independent because if coins are not replaced the outcome of next event will be effected.
2. A coin is flipped three times.
Independent because when a coin is flipped once its outcome doesn't effect the outcome of the coin flipped again
3. A bag contains 5 red balls and 3 green balls. A red ball is chosen followed by a green ball without replacement.
Not Independent because if balls are not replaced the outcome of next event will be effected.
4. A spinner contains 3 equal sectors labeled A, B and C. The spinner is spun twice.
Independent because when the spinner is spuned once its outcome doesn't effect the outcome of the spinner spun again
