Answer:
0.0793 = 7.93% probability that more than 5% of the guests are pollotarian and therefore she will not have enough pollotarian meals
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
3.5% of the people in the area where a large wedding is to be held are pollotarian.
This means that [tex]p = 0.035[/tex]
300 guests
This means that [tex]n = 300[/tex]
Mean and standard deviation:
[tex]\mu = p = 0.035[/tex]
[tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.035*0.965}{300}} = 0.0106[/tex]
What is the approximate probability that more than 5% of the guests are pollotarian and therefore she will not have enough pollotarian meals?
This is 1 subtracted by the pvalue of Z when X = 0.05. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.05 - 0.035}{0.0106}[/tex]
[tex]Z = 1.41[/tex]
[tex]Z = 1.41[/tex] has a pvalue of 0.9207
1 - 0.9207 = 0.0793
0.0793 = 7.93% probability that more than 5% of the guests are pollotarian and therefore she will not have enough pollotarian meals

Which of the following is a subspace of R^3? (A) All vectors of the form(0, a, a^2), (B) All vectors of the form(a+2, a, 0), (C) All vectors of the form (a, b, 2), (D) All vectors of the form(a, b, a-2b)
All vectors of the form(a, b, a - 2b) is a subspace of R³. So, the correct option is option(D).
Subspace:If W is a set of one or more vectors from a vector space V, then W is a subspace of V if and only if
If u and v are vectors in W, then u + v in W. ku is in W if k is any scalar and u is any vector in W.Now, check the options and find out the option which satisfy the subspace conditions.
A) All the vectors are of form (0, a,a²)
let (0,1,1) = u and v=(0,2,4) and both are belongs to { 0, a,a² : a∈R }, (0,0,0)∈ {0, a,a² : a∈R }.
u + v = (0,1,1) + (0,2,4) = (0,3, 5) not belongs to
{ 0, a,a² : a∈R }. So, this is not correct option.
B) Here, (0,0,0) does not belongs to
{0, a, a+2 : a∈R } because if a= 0 then a+2 =/ 0 .
So, it is also not subspace.
C) All vectors of the form (a, b, 2)
The third tuple is 2 which never be equal to zero. Hence, (0,0,0) does not belongs to (a, b, 2) and it is not form subspace.
D) All vectors of the form (a, b, a - 2b)
When a = 0 , b = 0 => (0,0,0) ∈(a, b, a - 2b)
let u = ( a1, b1 , a1- 2b1) and v = ( a₂, b₂ , a₂ - 2b₂)
and α∈R
u + v = ( a₁, b₁ , a₁- 2b₁ ) + ( a₂, b₂ , a₂ - 2b₂)
= ( a₁ +a₂ , b₁+b₂ , a₁+a₂ -2(b₁ - b₂)) €(a, b, a - 2b)
αu = α(a₁ , b₁ , a₁- 2b₁)

The value of variable x in the equation is x = -3y + 5/ 2
How to solve an equation for a variable?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign.
Therefore, the equation 2x + 3y = 5 can be solved for x as follows:
We have to make x the subject of the formula in the equation.
Subject of the formula is the variable which is expressed in terms of other variables involved in the formula.
Hence,
2x + 3y = 5
subtract 3y from both sides of the equation
2x + 3y = 5
2x + 3y - 3y = 5 - 3y

An account executive receives a base salary plus a commission. On $50,000 in monthly sales, the account executive receives $6500. On $60,000 in monthly sales, the account executive receives $6800.
(a) Determine a linear function that will yield the compensation y of the sales executive for a given amount of monthly sales x.
(b) Use this model to determine the account executive's compensation for $90,000 in monthly sales.

A) A linear function that will yield the compensation y of the sales executive for a given amount of monthly sales x is;
B) The account executive's compensation for $90,000 in monthly sales is; $300
How to model a linear equation?
The general equation of a line in slope intercept form is;
y = mx + b
where;
m is slope
b is y-intercept
x and y are provided in the problem: x = monthly sales and y = compensation
We will have to find m (Slope), which represents the commission percentage, and b (y-intercept), which represents the the base salary.
x₁ y₁ x₂ y₂
(50000, 6500) (60000, 6800)
Slope;
m = (y₂ - y₁) / (x₂ - x₁)
m = (6800 - 6500) / (60000 - 50000)
m = 300/10000
m = 3/100 = 0.03 = 3%
To find b, we have to take one of our ordered pairs [ (50000, 6500) or (60000, 6800) ] and plug it into the equation, y=mx+b.
Let's use (60000, 6800)
6800 = 0.03(60000) + b
6800 = 1200 + b
b = 6800 - 1200
b = $5600
The base salary = $5600
The equation is y = 0.03x + 5600
b) For $90000 in monthly sales, the executive's compensation is;
y = 0.03(90000) + 5600
y = 2700 + 5600

−0.76; There is a strong, negative association between discharge and speed.
−0.87; There is a strong, negative association between discharge and speed.
Answer:
The value of the correlation coefficient is 0.87, which means there is a strong, positive association between discharge and speed. A positive correlation means that as one variable increases, the other variable also increases. In this case, as the discharge of the Colorado River increases, the speed of the river also increases. The strength of the association is indicated by the magnitude of the correlation coefficient, which ranges from -1 to 1. A value of 0.87 is considered a strong positive correlation, indicating that there is a strong relationship between the two variables.

It is known that 25 % percent of Americans identify themselves as republican . In a random sample of n=20 Americans , what is the standard deviation of the number of republicans ? ( Round to 2 decimal places )
Using percentages, we know that out of 20 people, 5 people that is 25% of the random sample consider themselves as republicans.
What is the percentage?A percentage is a figure or ratio stated as a fraction of 100 in mathematics.
We must divide the value by the entire value to find the percentage, and then multiply the resulting number by 100.
As an illustration, 1% of 1,000 chickens is equal to 1/100 of 1,000, or 10 birds, and 20% of the quantity is equal to 20% of 1,000, or 200.
So, we have a random sample of 20 people.
n = 20
And we also know that 25% of Americans identify themselves as republicans.
Then the number of republicans in 20 people would be:
20/100 * 25

In Game 1, Emerson struck out 30 times in 90 times at bat. In Game 2, he struck out 40 times in 120 times at bat. In Game 3, Emerson struck out 42 times in 140 times at bat.
What percentage of times at bat did Emerson actually hit the ball?
%
Emerson actually hit the ball 32% of times at bat.
What is percentage ?
In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).
Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100. Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent. You divide the part of the whole by the whole and multiply the result by 100 to get the percentage.
Since in Game 1, Emerson struck out 30 times in 90 times at bat;
in Game 2, he struck out 40 times in 120 times at bat;
in Game 3, Emerson struck out 42 times in 140 times at bat;
To determine what percentage of times at bat did Emerson actually hit the ball, the following calculation must be performed:
(30 + 40 + 42) / (90 + 120 + 140) = X
112/350 = X
0.32 = X
Therefore, Emerson actually hit the ball 32% of times at bat.

Using combination we get 20475 teams can made up of 3 girls and 2 boys and 37128 teams can be selected with at least 3 girls.
Why does combination mean?Combinations are mathematical operations that count the number of potential configurations for a set of elements when the order of the selection is irrelevant. You can choose the components of combos in any order. Permutations and combinations can be mixed up.Since this is just a team of 5 children,
we have no of girls = 15
No of boys = 10
teams made up of 3 girls and 2 boys
girls out of 3 girls can be selected in ¹⁵C₃ ways and
2 boys out of 10 boys can be selected in ¹⁰C₂ ways.
[tex]\implies[/tex] ¹⁵C₃ X ¹⁰C₂
= 455*45 =20475 Ways
Teams can be selected with at least 3 girls
It is the probability of at least 3 girls which means P(3 girls,2 boys) or P(4 girls,1 boy) or P(5 girls, 0 boys)
[tex]\implies[/tex] ¹⁵C₃ X ¹⁰C₂ + ¹⁵C₄ X ¹⁰C₁ + ¹⁵C₅ X ¹⁰C₀
= 455 * 45 +1365*10+3003*1
=20475 +13650 +3003
=37128 ways

A certain game keeps track of the maximum and minimum scores obtained so far. If num represents the most recent score obtained, which of the following algorithms correctly updates the values of the maximum and the minimum?
following algorithms correctly updates the values, If num is less than the minimum, set the minimum equal to num. Otherwise, if num is greater than the maximum, set the maximum equal to num.
What is algorithm ?An algorithm is a process used to carry out a computation or solve a problem. In either hardware-based or software-based routines, algorithms function as a detailed sequence of instructions that carry out predetermined operations sequentially.The game records the highest and lowest scores that were earned. This indicates that the game already has the highest and lowest score stored in its memory.
Now, if a new score, num, is achieved, the game must compare num with the minimum and maximum scores in order to update the minimum and maximum scores. The minimum score is updated to the score, num if the most recent score, num, is lower than the minimum score.
Additionally, the maximum score is updated to the score, num if the most recent score, num, is higher than the maximum score.

C
The range of possible values for x is 4/11 < x < 8
How to determine the range of possible values for x?From the question, we have the following parameters that can be used in our computation:
Triangles = 2
On these triangles, we have the following angles
Angle 1 = 11x - 4
Angle 2 = 84
Angle 1 cannot exceed angle 2
So, we have
11x - 4 < 84
Add 4 to both sides
11x < 88
Divide
x < 8
Angle 1 cannot exceed be negative or 0
So, we have
11x - 4 > 0
Add 4 to both sides
11x > 4
Divide
x > 4/11
Hence, the range is 4/11 < x < 8
