Answer:

Step-by-step explanation:

Answer:

a) 8

b) 27

c) x+7

d) 5

Step-by-step explanation:

For a and b your are just adding 7

For c you are just writing the algebraic equation

For d you are just subtracting 7

Hope this helps!:)

Answer:

1. a. 8 years

   b. 27 years

   c. x+7 because x is an unknown value so it is x+7.

   d. 5 years old

Step-by-step explanation:

a, b, c, d it is the value they give you plus 7.

d. her sister is 5 years old because Britney is 7 years older than her. in this situation her sister is X years old, but they tell you what Britney's age is. so you do 12-7 because her sister is 7 years younger. 12-7= 5 so her sister is 5 years old. you can check this by doing 5+7, to get 12.

Answer:

  0

Step-by-step explanation:

The function is defined everywhere except at x=-6. The limit value is the function value at that point.

  f(6) = (6^2 -36)/(6 +6) = 0/12 = 0

The limit of the function is 0 as x → 6.

Answer:

A. -1/12

Step-by-step explanation:

This is the correct answer.

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]

Incluso podemos factorizar la respuesta final para obtener

[tex](\frac{1}{3}y^2+\frac{2}{3}xy-3)x[/tex]

Answer :

3.5 × 3.5 × 3.5 = 42.875

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.

Hope this answer helped! :)

Answer:

C. 61/pi/18

Step-by-step explanation:

I calculated logically

Answer:

x=35 degrees

Step-by-step explanation:

Since the other side is 90 degrees you would have to add 55 degrees + 35 degrees in order to get 90 degrees for both sides.

Answer:

Step-by-step explanation:

its perpedicular so it adds up to 90°, therefore 90-55=x and x =35

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 :))

Answer:

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!

Step-by-step explanation:

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)

"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."

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.

"It is the probability of an event occurring given that another event has already occurred."

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)

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: 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

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

Answer:

x = 3

Step-by-step explanation:

From the given parallelogram;

m<XWC = m<XYC

Given

m<XWC = 2x+5

m<XYC = 3x+2

Equate

2x+5 = 3x+2

2x - 3x = 2 - 5

-x = -3

x = 3

Hence the value of x is 3
