The probability that the sample will be rejected if five items from 1 lot is selected is 26/15504.
Given Industrial product is product in lots of 20. If sample contains more than one defective then the lot will be rejected.
Probability is the chance of happening an event among all the events possible. The probability lies between 0 and 1. The formula of calculating probability is as under:
Probability= number of items/ total items.
Sample from 1 lot =5
Samples in 1 lot=20
Lot will be rejected when 1 sample, 2 sample , 3 sample, 4 sample or all the samples are defective.
Probability that the lot will be rejected=[tex](5C_{2} +5C_{3} +5C_{4} +5C_{5})/20C_{5}[/tex]
=(10+10+5+1)/15504
=26/15504
Hence the probability that lot will be rejected if the lot is rejected if more than one defective is observed is 26/15504.

Solve for x HELP PLEASE!!!!!!!!
Answer:
5
Step-by-step explanation:
28 - 12 = 16
28 / 35 = 16 / 4x
28 = 4 * 7
35 = 5 * 7
16 = 4 * 4
4x = 4 * x
( 4 * 7 ) / ( 5 * 7 ) = ( 4 * 4 ) / ( 4 * x )
( 4 / 5 ) = ( 4 / x )
Cross multiply,
4 * x = 5 * 4
Divide 4 on both sides,

the nth term of another sequence is given by an bn 2 + the third term is 9 and the sixth term is 126. find the value of a and the value of b
The values of a and b of the given sequence are; a = 6 and b = -15
How to find the Nth Term of a Sequence?
We are given the formula for nth term of a sequence as;
an² + bn
We are given that;
Third term = 9
Sixth term = 126
Thus;
a₃ = 9 = a(3)² + b(3)
9a + 3b = 9 ------(1)
Similarly for the 6th term;
a(6)² + b(6) = 126
36a + 6b = 126 ------(2)
Multiply eq 1 by 2 to get;
18a + 6b = 18 ------(3)
Subtract eq 3 from eq 2 to get;
18a = 108
a = 6
18(6) + 6b = 18
6b = 18 - 108
6b = -90
b = -90/6
b = -15

The percentages for each acid are:
0% acid ⇒ percentage disolved = 0%33% acid ⇒ percentage disolved = 1%66% acid ⇒ percentage disolved = 2%100% acid ⇒ percentage disolved = 4.2%How to get the percentages?
Here we just need to use the given formula:
[tex]percent\ disolved = \frac{initial\ mass - \ final \ mass}{initial \ mass}*100 \%[/tex]
For the 0% acid, the initial and final mass are the same:
initial mass = final mass = 10.3g
Then the percent dissolved is:
[tex]percent\ disolved = \frac{10.3g - 10.3g}{10.3g}*100 \% = 0 \%[/tex]
For the 33% acid we have:
initial mass = 10.1gfinal mass = 10gThen:
[tex]percent\ disolved = \frac{10.1g - 10g}{10.1g}*100 \% = 1 \%[/tex]
For the 66% acid:
initial mass = 10gfinal mass = 9.8g[tex]percent\ disolved = \frac{10g - 9.8g}{10g}*100 \% = 2 \%[/tex]

Levi needed to get his computer fixed. He took it to the repair store. The technician at
the store worked on the computer for 5.5 hours and charged him $59 for parts. The
total was $361.50. Which equation could be used to determine c, the cost of labor per
hour?
Answer:
$55
Step-by-step explanation:
Let c = cost of labour per hour
1) Set up an equation, where hours is denoted by c.
5.5c + 59 = 361.50
5.5c = 361.50 - 59
5.5c = 302.50
c = 302.50/5.5
c = 55
Therefore, the technician took $55 per hour.

How many distinct pairs of positive consecutive integers have a product less than 10,000?
Please explain it step-by-step
Step-by-step explanation:
Let the consecutive positive integer be x , x+1
now, we know that there product is less then 10000
so, x(x+1) = 10000
x² + x - 10000 = 0
On solving the quadractic equation,
we get the roots = (-100.50124999219 ), (99.501249992188)
since we are asked for less then 10000 we can approximate the answer to x = 99.5
Answer:
99.5
Step-by-step explanation:
Let the consecutive positive integer be n , n+1
now, we know that there product is less then 10000
so, n(n+1) = 10000
So, the question asked " Less than 10,000 " so, we get the roots = (-100.50124999219 ), (99.501249992188)
n² + n - 10000 = 0

The area of the square LMNP is 50 square units
How to determine the area of the square?The circumference of the circle is given as:
C = 10π
Circumference is calculated as:
C = 2πr
So, we have:
2πr = 10π
Divide by 2π
r = 5
This represents the length OM
The length PM is calculated as:
PM = 2 * OM
This gives
PM = 2 * 5
PM = 10
The length (PN) of the square is then calculated as:
PM = PN√2
This gives
10 = PN√2
Square both sides
100 = PN^2 * 2
Divide by 2
50 = PN^2
Rewrite as:
PN^2 = 50

The sesame street tube bought by the blue bird costs $177.92 which contained one gallon of toothpaste.
Given,
cost of regular toothpaste = $1.39 for 2.7 ounce tube
But the bird took a tube of toothpaste that contained one gallon of toothpaste.
One gallon = 128 ounces
∴the total price at which the toothpaste is brought = price of normal toothpaste × one gallon(128 ounces)
= 1.39 × 128
=$177.92
Here we can observe that a gallon contains 128 ounces. so we need to multiply to the initial cost of the toothpaste to get the final amount of the toothpaste bought by the bird.
Hence the price at which the bird bought the toothpaste is $177.92

UT = 2 × 46° = 92°
the sum of the arcs in a circle = 360° , that is

Pete is ahead of nick by 11 meters. Oliver is ahead of manny by 10 meters. Oliver is ahead of pete by 5 meters. How far is the runner in first place ahead of the runner
Answer:
The runner in first place is 16 meters ahead of the runner in last place
Step-by-step explanation:
There are 4 boys racing - Pete, Nick, Manny, and Oliver.
Pete is 11 meters ahead of Nick, Oliver is 10 meters ahead of Manny, and Oliver is ahead of Pete by 5 meters.
This means Oliver is ahead of the other three racers, putting him in first place, and Manny is between Nick and Pete.
So in order to find out the distance between the racer in first place (Oliver) and the racer in last place (Nick), add the distance between Oliver and Pete and the distance between Pete and Nick.
Add the distances: 5 + 11
Therefore, the runner in first place (Oliver) is 16 meters ahead of the runner in last place (Nick).
