A quality control inspector has drawn a sample of 11 light bulbs from a recent production lot. Suppose 20% of the bulbs in the lot are defective. What is the probability that less than 7, but more than 4 bulbs from the sample are defective
Answers
Answer:
0.04845
Step-by-step explanation:
Probability that less than 7 but more than 4 bulbs from the sample are defective :
P(4 < X < 7) = P(x = 5) + P(x = 6)
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
From the question :
p = 0.2 ; 1 - p = 0.8 ; n = 11
P(x =5) = 11C5 * 0.2^5 * 0.8^6 = 0.03876
P(x = 6) = 11C6 * 0.2^6 * 0.8^5 = 0.00969
P(4 < X < 7) = P(x = 5) + P(x = 6)
P(4 < X < 7) = 0.03876 + 0.00969
P(4 < X < 7) = 0.04845

Hi there!
[tex]\large\boxed{x = 40}[/tex]
We can solve for x knowing that the sum of interior angles in a triangle is 180°.
The square at the bottom indicates a right angle, or 90°. Therefore:
180 = 90 + x + (x + 10)
Combine like terms:
180 = 100 + 2x
Subtract 100 from both sides:
180 - 100 = 2x
80 = 2x
Divide both sides by 2:
x = 40.
Answer:
hi
Step-by-step explanation:
x+90⁰+x+10=180
x+x+10=180-90
2x+10=90
2x=90-10
2x=80
x=80/2
x=40

When using the median fit method to model data, you should Determine three y intercepts by using each summary point along with the slope.
What is the median fit method?This is a model for coming up with trend lines to represent the data given by a data set by dividing the given data into sections where the data points are equal in number.
As there will be three sections, it is important that three y intercepts are determined using summary points and the slope.

11. If you randomly selected 500 U.S. homes, about
how many would be heated with fuel oil?
Answers
Answer:
50
Step-by-step explanation:
Given
Total number of US houses = 500
If 10% were affected by fuel oil
Total number affected by fuel oil = 10% of 500
Total number affected by fuel oil = 0.1 * 500
Total number affected by fuel oil = 50
Hence 50 houses were affected by fuel oil

Answer:
x = [tex]\frac{19+\sqrt{365}}{2}, \frac{19-\sqrt{365}}{2}[/tex]
Step-by-step explanation:
1. Move everything to one side of the equation.
x^2 - 19x - 1 = 0
2. Use the quadratic formula where a = 1, b = -19, and c = -1.
x = (-b +- sqrt(b^2-4ac)) / 2a
If you plug those numbers into that formula, you will get the result listed above
