A pharmaceutical company receives large shipments of aspirin tablets. The acceptance sampling plan is to randomly select and test 39 tablets, then accept the whole batch if there is only one or none that doesn't meet the required specifications. If one shipment of 4000 aspirin tablets actually has a 5% rate of defects, what is the probability that this whole shipment will be accepted? Will almost all such shipments be accepted, or will many be rejected?
Probabilities are used to determine the chances of a shipment being accepted or rejected
The probability that a shipment will be accepted is 0.4129Many shipments will be rejectedHow to determine the probabilityThe rate of defect is 5%.
So, the probability that a tablet is not defect is 95%
The probability that there is no defect out of the 39 selected tablets is:
[tex]P(None) = 0.95^{39}[/tex]
[tex]P(None) = 0.1352[/tex]
The probability that there is one defect out of the 39 selected tablets is:
[tex]P(One) = 39 * 0.05 * 0.95^{38}[/tex]
[tex]P(One) = 0.2777[/tex]
Add both probabilities
[tex]P(Accepted) = 0.1352 + 0.2777[/tex]
[tex]P(Accepted) = 0.4129[/tex]
Hence, the probability that a shipment will be accepted is 0.4129
The above probability is less than 0.5.
This means that many shipments will be rejected

Corresponding angles converse theorem
Step-by-step explanation:
Angles x and y are corresponding angles.
This makes the lines parallel by the converse of that theorem.
This makes it similar by the corresponding angles converse theorem.
Definition of converse
the reverse of another
The corresponding angles theorem is for the congruency of the angles by parallel lines. Here we want to see if the lines are parallel given the congruency of the angles.
We can flip the operation, checking to see if the angles are congruent, which proves that the lines are parallel.

1 km = 0.62 mi. The distance between Lowell and Shelby is 285
miles. How many kilometers is this?
Round your answer to the nearest whole kilometer.
Answer:
459
Step-by-step explanation:
Since to find out mile to kilometer you divide the mile by 1.609 would equal 458.66304 and rounding it to the nearest whole kilometer is 459 there is you answer.
The distance between Lowell and Shelby is approximately 460 kilometres.
Given that information:
1 km = 0.62 miles
Also given the distance between Lowell and Shelby is 285 miles.
To convert miles to kilometres, use the conversion factor:
1 mile = 1.60934 kilometres
Now calculate the distance in kilometres as follows:
Distance in kilometres = 285 miles × 1.60934 km/mile
Distance in kilometres ≈ 459.7 kilometres.
Now, round the answer to the nearest whole kilometre as follows:
Distance in kilometres ≈ 460 kilometres.
Hence, the distance between Lowell and Shelby is approximately 460 kilometres.

A rectangle has an area of 893.2 square yards and a height of 31.9 yards. What is the length of the base?
Area = height x length
893.2 = 31.9 x length
To find length divide both sides by the height:
length = 893.2 / 31.9
Length = 28 yards
Answer:
4.84 yards
Step-by-step explanation:
You plug in the values into the formula for the Area of a triangle
a car park charges 1.50 to each car entering. the car park only accepts £1 coins and 50p coins. here are the coins collected on a particular day. number of £1 coins: 172 number of 50p coins:256 making the assumption that all drivers paid the exact amount due on that day, work out the percentage of drivers that paid with three 50p coins
Subtract the amount of £1 coins from 50p coins:
256-172 = 84
84/3 coins = 28 people paid with 3 coins.
172 people paid using £1 coins
172 + 28 = 200 total people
percent who used 3 coins = 28/200 = 0.13 x 100 = 14%

If the end behavior is increasing on the left and decreasing on the right, which statement must be true about the function?
The degree is even and the leading coefficient is positive.
The degree is even and the leading coefficient is negative.
The degree is odd and the leading coefficient is positive.
The degree is odd and the leading coefficient is negative.
Using limits, the correct statement is given by:
The degree is odd and the leading coefficient is negative.
How the end behavior of a function f(x) is found?It is found by it's limits as x goes to infinity. On the left, it is given by:
[tex]\lim_{x \rightarrow -\infty} f(x)[/tex]
On the right, it is given by:
[tex]\lim_{x \rightarrow \infty} f(x)[/tex]
Since it is a limit as x goes to infinity, we only consider the term with the highest degree and it's leading coefficient.
Hence, the behavior described, that is, [tex]\lim_{x \rightarrow -\infty} = \infty, \lim_{x \rightarrow \infty} = -\infty[/tex] happens when:

A student was asked to find the volume of the solid where the
inner cylinder is hollow. She incorrectly said the volume is
954.56 in.3. Find the volume of the solid. Use 3.14 for 1. What
mistake might the student have made?
The volume of the solid is 753.6 in³
Volume
Volume is the amount of space occupied by a three dimensional figure or shape.
The volume of the solid with hole = (π * (8/2)² * 16) + (1/3)(π * (8/2)² * 9)= 954.56 in³
Volume of hole = (π * (2)² * 16) = 200.96 in³
Volume of solid = 954.56 in³ - 200.96 in³ = 753.6 in³

Find the values of x and y in the triangle below.
(Please hurry)
Answer:
x = 10.4
y = 9
Step-by-step explanation:
Suppose the triangles are similar
x/26 = 8/20 (side lengths must be proportional) cross multiply expressions
20x = 208 divide both sides by 20
x = 10.4
same goes for y
6/(6+y) = 8/20 cross multiply expressions
120 = 8y + 48 subtract 48 from both sides
72 = 8y divide both sides by 8
9 = y
