Answer: Our required probability is 0.947.
Step-by-step explanation:
Since we have given that
Number of light bulbs selected = 30
Probability that the light bulb produced in a facility are defective = 2.8% = 0.028
We need to find the probability that fewer than 3 defective bulbs are found.
We will use "Binomial distribution":
n = 30, p = 0.028
so, P(X>3)=P(X=0)+P(X=1)+P(X=2)
So, it becomes,
and
So, the probability that fewer than three defective bulbs are defective is given by
Answer:
of outdoor carpet is needed for the hole
Step-by-step explanation:
The question is not properly formatted
The expression for the dimension is
Given data
Area A = ?
Length l = 4ft
Width w= 2ft
Height h = 5ft
since we are required to find the area in
we do not need the height for our calculation
we know that the expression for area is
The graph of the journey is shown in the speed-time graph below
At the time = 3 minutes, Peter would have achieved the speed V.
The distance he travelled is the area under the line as shown in the graph
We first need to find the V by using the area of a rectangle formula
so V=220
the gradient the f slope then given as
There will be no angle between the lines as the lines are parallel.
We are given the two lines:
2 x - 3 y + 5 = 0 and 2 x - 3 y - 7 = 0
Slope of the line 2 x - 3 y + 5 = 0:
-a₁/b₁ = -2/-3 = 2/3
Slope of the line 2 x - 3 y - 7 = 0
-a₂/b₂ = -2 / -3 = 2/3
Since both the lines have same slopes, they are parallel lines and will not intersect each other.
So, there will be no angle between the lines.
