A researcher randomly surveyed 1,477 farmers to determine the geographical region in which they farm and the types of crops that grow there. The two-way table displays the data.
Suppose a farmer from this survey is chosen at random. Let M = farmer lives in the Midwest and V = farmer grows vegetables. What is the value of P(V|M)?
A) 251/72
B) 168/437
C) 723/1477
D) 251/365
Answer:
the answer is 251/723
Step-by-step explanation:
just took the test and also its asking for the (midwest farmer vegetables) so youd look at midwest and find the vegetable row and it would be 251 then since its asking for only vegetables you'd go across the row and locate the total vegetables which is 723. THE A OPTION IS MISTYPED ITS 251/723.
The value of P(V|M) is 251/365.
The correct answer is option (D)
What is probability?"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."
Formula of the probability of an event A is:P(A) = n(A)/n(S)
where, n(A) is the number of favorable outcomes,
n(S) is the total number of events in the sample space.
What is conditional probability?"It is the probability of an event occurring given that another event has already occurred."
Formula for conditional probability:The probability of event A occurring given that event B has already occurred is,
P(A|B) = P(A ∩ B)/P(B)
where, P(A ∩ B) the joint probability of events A and B
For given example,
n(S) = 1477
Event M = farmer lives in the Midwest
⇒ n(M) = 365
So, the probability of farmer lives in the Midwest would be,
⇒ P(M) = n(M)/n(S)
⇒ P(M) = 365/1477
And event V = farmer grows vegetables.
⇒ n(V) = 723
The probability of farmer grows vegetable would be,
⇒ P(V) = n(V)/n(S)
⇒ P(V) = 723/1477
The number of farmers who grows vegetables and lives in the Midwest are,
n(A ∩ B) = 251
So, the probability that the farmers grow vegetables and live in the Midwest would,
⇒ P(M ∩ V) = n(A ∩ B)/n(S)
⇒ P(M ∩ V) = 251 / 1477
Now, we need to find P(V|M).
Using the formula of conditional probability,
⇒ P(V|M) = P(M ∩ V) / P(M)
⇒ P(V|M) = (251/1477) / (365/1477)
⇒ P(V|M) = 251/365
The correct answer is option (D)

Emergency rooms have reason to suspect that visits increase on the weekends. A recent report indicates that Monday through Thursday represent 10% per day of the weekly total visits while Friday accounts for 15%, Saturday 25% and Sunday 20%. If your ER has the following pattern, Monday, 120, Tuesday, 130, Wednesday 110, Thursday 95, Friday 160, Saturday 280 and Sunday 105. Does your facility have the same pattern as the recent report at the 10% level
Answer:
No the facility dose not have the same pattern as the recent report at the 10% level
Step-by-step explanation:
To determine if the Facility have the same pattern ; Perform Chi squared test for Goodness of fit
state the hypothesis
H0 : μ = same pattern
Ha : μ ≠ same pattern
expected frequency ( E ) = proportion * summation of frequency
summation of frequency = 1000
degree of freedom = 7 - 1 = 6
Next : Calculate the expected frequency (E) , (O-E)²/E. given that the observed frequency and expected proportion is given
For Monday
expected frequency = proportion * frequency = 0.1 * 1000 = 100
(O-E)²/E. = ( 120 - 100 )^2 / 100 = 4.0.
observed frequency ( O ) , expected frequency ( E )
For Tuesday
E = 0.1 * 1000 = 100
(O-E)²/E = ( 130 - 100 )^2 / 100 = 9.0
Repeat same calculations for Wednesday through Sunday
Then perform Chi-squared test
X² = Σ(O-E)²/E = 63.642
∝ = 0.1
df = 6
hence P-value = 0.000 ( =chisq.dist.rt(test-stat,df)
since P-value < ∝ ; we will fail to reject Ha hence we reject H0

Answer:
El polinomio final es:
[tex]=x(\frac{1}{3}y^{2}-3+\frac{2}{3}xy)[/tex]
Step-by-step explanation:
Agrupemos los términos con las mismas variables:
[tex](\frac{2}{3}xy^{2}-\frac{1}{3}xy^{2})+(2x-5x)+\frac{2}{3}x^{2}y=[/tex]
Sumemos estos terminos:
[tex]=\frac{1}{3}xy^{2}-3x+\frac{2}{3}x^{2}y=[/tex]
Podemos ver que los tres terminos tienen x, asi que podemos factorizar x.
Por lo tanto el polinomio final es:
[tex]=x(\frac{1}{3}y^{2}-3+\frac{2}{3}xy)[/tex]
Espero te haya servido.
El resultado de simplificar [tex]\frac{2}{3}xy^2+2x-\frac{1}{3}xy^2+\frac{2}{3}x^2y-5x[/tex] es
[tex](\frac{1}{3}y^2+\frac{2}{3}xy-3)x[/tex]
El polinomio que queremos simplificar es
[tex]\frac{2}{3}xy^2+2x-\frac{1}{3}xy^2+\frac{2}{3}x^2y-5x[/tex]
primero, recopilamos términos similares
[tex]\frac{2}{3}xy^2-\frac{1}{3}xy^2+\frac{2}{3}x^2y+2x-5x[/tex]
luego simplificamos los términos similares. Es decir
Para el [tex]xy^2[/tex] términos:
[tex]\frac{2}{3}xy^2-\frac{1}{3}xy^2=(\frac{2}{3}-\frac{1}{3})xy^2\\\\=(\frac{1}{3})xy^2=\frac{1}{3}xy^2[/tex]
y para el [tex]x[/tex] términos:
[tex]2x-5x=(2-5)x\\=(-3)x=-3x[/tex]
la [tex]x^2y[/tex] términos ya está simplificado. Así que déjalo así.
Este es el trabajo total:
[tex]\frac{2}{3}xy^2-\frac{1}{3}xy^2+\frac{2}{3}x^2y+2x-5x\\\\=(\frac{2}{3}-\frac{1}{3})xy^2+\frac{2}{3}x^2y+(2-5)x\\\\=(\frac{1}{3})xy^2+\frac{2}{3}x^2y+(-3)x\\\\=\frac{1}{3}xy^2+\frac{2}{3}x^2y-3x[/tex]

Last week Jovanna ran 30 miles more than Rachel. Jovanna ran
47 miles. How many miles did
Rachel run?
A. 30 + x = 47
B. 30 - x = 47
C. 47 + x = 30
D. 47x = 30
Answer: A
Step-by-step explanation:
if rachel is 'x' and jovanna ran 30 more miles than her, then jovanna ran 30+x miles
we know that jovanna ran 47 miles so we set both values equal to each other
30 + x = 47
which is option A :))

Hello! answer: r = 7
Step-by-step explanation:
Hi im sorry I will try to explain this the simplest way possible! so all of this will add up to 180 we know 1 angle is 55 and the 1 that isnt labelled is 90 because its a complementary angle leta add those and subtract so we can figure out what our last angle will have to equal so... 55 + 90 = 145
180 - 145 = 35 so now we know the last angle will have to equal 35 r is just a place holder its just representing something multiplied by 6 subtracted by 7 will equal 35 so...
6 × 7 = 42 and 42 - 7 = 35 So 7 is r!! Hope that helps!

What is the approximate probability that a randomly selected student is satisfied with his or her school's variety of extracurricular activities?
O A. 0.308
OB. 0.468
O c. 0.617
OD. 0.658
O E 0.790
Answer: D. 0.658
Step-by-step explanation:
A randomly selected student would be from either of the high schools so both high schools need to be taken into account.
The probability that a randomly selected student is satisfied with his or her school's variety of extracurricular activities can be calculated as:
= Number of students from both high schools that are satisfied / Total number of students in both high schools
= 79 / 120
= 0.658
The length of a rectangle is 2 yards longer than its width. If the perimeter of the rectangle is 64 yards, find its length and width.
Answer:
Length: 17 yards
Width: 15 yards
Step-by-step explanation:
If the length is 2 yards longer than the width, then the width is w, and the length is w+2
Equation for perimeter is [tex]P =2l+2w[/tex], where:
P = Perimeter
l = length
w = width
Plug in the values:
64 = 2(w+2) + 2w
Distribute:
64 = 2w + 4 + 2w
Combine like terms:
64 = 4w + 4
Subtract 4 from both sides:
60 = 4w
Divide 4 from both sides:
15 = w
So if w = 15, then
Width = w, which is 15 yards.
Length = w+2, which is 15+2 = 17 yards.

Two gamblers, call them Gambler A and Gambler B flip a coin repeatedly. The coin is unfair and comes up heads 2/3 of the time. Gambler A wins one dollar from Gambler B, when a head is tossed. Conversely Gambler B wins one dollar from Gambler A when a tail is tossed. The coin tosses are independent. The game ends when one of the gamblers runs out of money. There are 5 dollars in the pot. Determine the probability that Gambler A wins the game if he starts with I dollars. Here I
Answer:
≈ 0.52
Step-by-step explanation:
P( head ) = 2/3 , P( tail ) = 1/3
when a head is tossed ; Gambler A wins $1
when a tail is tossed : Gambler B wins $1
Determine the P( Gambler A wins the game ) if he starts with I dollars
Assuming I = $1
n = 5
p ( head ) = P( winning ) = 0.66
p( losing ) = 0.33
applying the conditional probability in Markov which is ;
Pₓ = pPₓ₊₁ + (1 - p) Pₓ₋₁
P( 1) = 0.66P₂ + 0.33P₀
resolving the above using with Markov probability
P( 1 ) = 0.51613
hence the probability of Gambler A winning the game if he starts with $1
≈ 0.52
