PROBABILITY!!! Hospitals typically require backup generators to provide electricity in the event of a power outage. Assume that emergency backup generators fail 35% of the times when they are needed. A hospital has two backup generators so that power is available if one of them fails during a power outage. Complete parts (a) and (b) below.
Answers
A) In the event of a power loss, the possibility of both generators failing is 0.1225.
B) (i) In the case of a power outage, having a functioning generator may be anticipated 87.75% of the time.
(ii) During a power outage, it may be anticipated that both generators will malfunction roughly 12.25% of the time.
Probability: The probability of an occurrence is defined as the ratio between the number of positive outcomes to a certain event and the entire number of potential outcomes.
Complementary Events: When event A is specified, the complement of that event A does not take place.
Union of two events: The term "union of two events" refers to the collection of outcomes that are either related to both occurrences or one of the two events.
The intersection of two events: The intersection of two events refers to the group of results that are related to both occurrences.
Independent Events: If the occurrence of one event does not influence the occurrence of another event, then two occurrences A and B are said to be independent events. To put it another way, if the occurrence of event A has no bearing on the occurrence of event B, then the two occurrences A and B are independent.
A) The likelihood that both generators would malfunction during a power outage is calculated as follows:
According to the data provided, emergency backup generators malfunction 35% of the time when they are required. The probability value is 0.35 in this case.
The required probability is,
P⎝|⎛Bothgeneratorsfailduringapoweroutage⎠|⎞
= ⎣⎡P(Firstgeneratorfail) × P(Secondgeneratorfail)⎦ |⎤
= 0.35 × 0.35 = 0.1225
When there is a power outage, the likelihood that both generators will fail is calculated by multiplying the likelihood that the first and second generators will fail. During a power outage, the failure of both generators may be anticipated roughly 12.25% of the time.
B) (i) The likelihood of having a functional generator during a power outage is calculated as indicated below:
The required probability is,
P⎝|⎛Workinggeneratorintheeventofapoweroutage⎠|⎞
= 1−P⎝|⎛Bothgeneratorsfailduringapoweroutage⎠|⎞ =
1−0.1225 = 0.8775
The likelihood that a generator will operate in the case of a power loss is calculated by deducting the likelihood that both generators would malfunction from the overall likelihood. In the case of a power outage, having a functioning generator may be anticipated 87.75% of the time.
(ii) The likelihood that a patient will require hospitalization or not is determined as follows:
When there is a power outage, there is a 12.25% chance that both generators will malfunction; this means that they will malfunction roughly 10% of the time.
It is obvious that it is possible to anticipate that during a power outage, both generators will fail roughly 12.25% of the time, suggesting that this probability is low enough to not have an effect on patients' health.

Identify the function family to which f(x)=x+3 belongs.
A. Constant B. Linear C. Absolute value D. Quadratic
Answers
The function f(x)=x+3 belongs to linear category.
For a function to be linear it must have an single variable and also the maximum power to that variable in the equation must be 1.
In a linear variable there is always single value possible in a equation.
In the function also there is only one value at one time but it varies according to the function change.
Here the function f(x)=x+3 will vary as the value of x changes.
For x=1 the value of f(1)=4
For x=2 the value of f(2)=5 and so on
The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The whole set of values that the function's output can produce is referred to as the range. The set of values that might be a function's outputs is known as the co-domain.

Find the measure of the angle AEC that is supplementary to the angle AED in the diagram below. Enter only the number.
Answers
The measure of angle AEC is 115°.
What are Supplementary angle?
Supplementary angle are those angles whose sum up are 180 degree.
Given that;
Measure of angle AED = 65
The angle AEC is supplementary to the angle AED.
Now, The angle AEC is supplementary to the angle AED.
Hence, ∠ AEC + ∠AED = 180°
Since, Measure of angle AED = 65°
So, ∠ AEC + ∠AED = 180°
⇒ ∠ AEC + 65° = 180°
⇒ ∠ AEC = 180° - 65°
⇒ ∠ AEC = 115°
Therefore, The measure of angle AEC is 115°.

The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line. The origin for this usage is unknown, however it may be found in O'Brien's (1844) and Todhunter's (1888) formulations of the equation for a straight line.
The ratio of the "vertical change" to the "horizontal change" between (any) two unique points on a line is used to compute slope. The ratio may occasionally be written as a quotient ("rise over run").

The solution for x from the linear equation is x=(n+p)/m .
Linear equation is a equation where the greatest degree of the variable is 1 in the equation.
A basic linear equation in the variable x is of the form ax+b =0 where b is a constant and a is the co-efficient of x.
To solve a linear equation for x we use the simple mathematical operations to make x the subject of the formula.
Given equation is:
mx=n+p
We have to find the value of x.
So we can see that the variable x has a constant co-efficient m
to make x the subject we divide both sides of the equation by m.
Therefore:
mx÷m=(n+p)÷m
or, x=(n+p)/m
So on solving the linear equation we get the value of x as (n+p)/m

Answer:
34,621
Step-by-step explanation:
Well as it may look hard it is simpler than you think
389*89 looks like a big number right? lets break it down into small pieces!
lets split up 389 into hundreds, tens, and ones.
So that will make it 300, 80, and 9!
Since we have to make 89 more of those numbers, lets try out a simple number in there!
Lets look at 9*89
9*9= 81
9*80=720
This means the answer is 801!
we will use this number later!
Now lets move on to 80*89!
80*9=720
80*80=6400
We will get 7120 if we add them!
we will also use that number later!
Now finally, 300*89!
300*80=24000
300*9=2700
We will get 26700!
Now finally, we add up all the three answers we got!
801 + 7120 + 26700 = 34621
This means the final answer is 34,621! I hope this helps!
