(a) The probability of each possible number of sets that are acceptable without any adjustment can be found using the binomial distribution formula:
P(x) = (n choose x) * p^x * (1-p)^(n-x)
Where:
P(x) is the probability of x successes in n trials
n is the number of trials (in this case, the number of sets produced in a week)
x is the number of successes (in this case, the number of sets that are acceptable without any adjustment)
p is the probability of success (in this case, the probability that a set is acceptable without any adjustment, which is 0.70)
Plugging in the values, we get:
P(0) = (3 choose 0) * 0.70^0 * (1-0.70)^(3-0) = 0.028
P(1) = (3 choose 1) * 0.70^1 * (1-0.70)^(3-1) = 0.081
P(2) = (3 choose 2) * 0.70^2 * (1-0.70)^(3-2) = 0.162
P(3) = (3 choose 3) * 0.70^3 * (1-0.70)^(3-3) = 0.126
(b) To find the expected number of sets that are tested and found to be acceptable without adjustment, we can use the formula:
E(x) = n * p
Plugging in the values, we get:
E(x) = 3 * 0.70 = 2.1
The expected number of sets that are tested and found to be acceptable without adjustment is 2.1.
(c) The cumulative probability distribution for the number of sets that are tested and found to be acceptable without adjustment is the sum of the probabilities of each possible number of successes. For example, the probability of 0 or 1 successes is the sum of the probabilities of 0 and 1 successes: P(0 or 1) = P(0) + P(1) = 0.028 + 0.081 = 0.109. The probability of 0, 1, or 2 successes is the sum of the probabilities of 0, 1, and 2 successes: P(0 or 1 or 2) = P(0) + P(1) + P(2) = 0.028 + 0.081 + 0.162 = 0.271.
The cumulative probability distribution for the number of sets that are tested and found to be acceptable without adjustment is:
P(0) = 0.028
P(0 or 1) = P(0) + P(1) = 0.028 + 0.081 = 0.109
P(0 or 1 or 2) = P(0) + P(1) + P(2) = 0.028 + 0.081 + 0.162 = 0.271
P(0 or 1 or 2 or 3) = P(0) + P(1) + P(2) + P(3) = 0.028 + 0.081 + 0.162 + 0.126 = 0.397
The corresponding graph would be a step function with a step at each possible value of x (in this case, 0, 1, 2, and 3) and the corresponding probability at each step.

Step-by-step explanation:
Given that ABCD is a rectangle, where EC=7 x-3 and AE=4 x+8 . Find DE.
The length of side DE of the rectangle ABCD is 11/5 units .
What is rectangle?
In euclidean plane geometry, a rectangle may be a quadrilateral with four right angles. It also can be outlined as: an angular quadrilateral, since angular means all of its angles square measure equal; or a tetragon containing a right angle.
Main body:
given:
AE = 4x+8 -----------(1)
CE = 7x - 3 -----------(2)
as we know diagonal of rectangle bisect each other , which means AE = CE
using the property , we get
4x+ 8 = 7x -3
taking like terms to one side,
7x - 4x = 8+3
3x = 11
x = 11/3
put the value of x in any equation,
AE = 4(11/3) +8
AE = 44/3 +24/3
AE = 68/3
as AE = DE
Hence the value of DE is 68/3 units.

0 = x² + 6x - 72
the general solution to such a quadratic equation

is
x = (-b ± sqrt(b² - 4ac))/(2a)

x = (-6 ± sqrt(6² - 4×1×-72))/(2×1) =

What is sales tax?A sales tax is a tax levied by a government on the sale of certain goods and services. Generally, laws allow the seller to collect tax funds from the consumer at the point of sale. A use tax is a tax on goods or services paid directly to a governing body by a consumer.
Given:
Bill at dinner was before tax and tip = $58.24
Sales tax = 6%
Tip = 18%
As per the question:

Sum of interior angles of a triangle.The interior angles of a triangle have a total sum of 180°.
Considering the triangle with interior angles: y, 51°, and 62° we have that;
y + 51° + 62° = 180°
y + 113° = 180°
y + 113° - 113° = 180° - 113° {subtract 113° from both sides}
y = 67°
the exterior angle x and the angle y lie on a straight line, so they sum up to 180°.
x + 67° = 180°
x + 67° - 67° = 180° - 67° {subtract 67° from both sides}
x = 113°

Describe a linear equation using an example.
An equation with only one variable is referred to as a linear equation in one variable.
It has the mathematical formula Ax + B = 0, where A and B can be any two real numbers, and x is an unknowable variable with just one possible value. One such linear equation in one variable is 9x + 78 = 18.
Consider the provided information,
Andy walked [tex]2\frac{3}{4}[/tex] mi at a constant speed of [tex]2\frac{1}{2}[/tex] mi/h.
As we know
Time = distance/speed
= [tex]\frac{2\frac{3}{4} }{2\frac{1}{2} }[/tex]
= [tex]\frac{11/4}{5/2}[/tex]
= 11/40
Therefore, Andy takes 1.1 hours.
Beth walked 1 1/2 mi at a constant speed of 1 1/8 mi/h .
time = [tex]\frac{1 1/2}{ 1 1/8}[/tex]

Therefore, Beth takes 1.33 hours.
Cindy walked for 1 h and 24 min at a constant speed of 1[tex]\frac{1}{4}[/tex] mi/h.
1 hour 24 min = 1 + 24/60 = 1.4 hours

Answer:
third option
Step-by-step explanation:
sinX = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{YZ}{XY}[/tex] = [tex]\frac{3}{\sqrt{34} }[/tex]
tanY = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{XZ}{YZ}[/tex] = [tex]\frac{5}{3}[/tex]
The table summarizes results from 975 pedestrian deaths that were caused by automobile accidents.
Driver
Intoxicated? Pedestrian Intoxicated?
Yes No
Yes 48 78
No 241 608
If one of the pedestrian deaths is randomly selected, find the probability that the pedestrian was not intoxicated or the driver was intoxicated.
Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol.
Therefore, the probability of the first case : 94.5% and second case:9.7%
Define probability.the likelihood that an event will take place. The proportion of feasible outcomes to outcomes in an exhaustive set of equally likely outcomes that result in a particular event. a field of mathematics that focuses on the investigation of probability.
Here,
Thus, the probabilities of following cases comes out to be:
1) The odds that either the pedestrian or the driver weren't are
=>(246+603+83)*100/986
=>(932/986)*100 =94.5%
2) The likelihood that both incidents involved inebriated pedestrians is equal to
=>(305/978)*(304/977)*100 = 9.7%
Therefore, the probability of the first case : 94.5% and second case:9.7%
