Joe, Kent, Bryan and Julie scored an average of 63 mark in Mathematics test. If we know that Julie's score qas 25% of Joe's score. Bryan scored 10 more marks thsn Joe and Kent scored 18 fewer marks than Joe. What is the total score of kent and bryan?​

Answers

Answer 1
J = Julie
B = Bryan
O = Joe
K = Kent

(J + B + O + K) / 4 = 63

J = .25O
B = O + 10
K = O - 18

Substitute:
((.25O) + (O + 10) + O + (O - 18)) / 4 = 63
(3.25O - 8) / 4 = 63
3.25O - 8 = 252
3.25O = 260
O = 80

K = O - 18
K = 80 - 18
K = 62

B = O + 10
B = 80 + 10
B = 90

Therefore,
B + K = 152

Favor Oppose No Opinion TotalDemocrat 320 150 50 520Republican 125 345 10 480Total 445 495 60 1000If the group surveyed represents the people of the United States, what is the probability that a citizen selected at random will favor reducing industries' carbon emissions, given that the person is a Republican? (Enter your probability as a fraction.)

Answers

Answer:

1 / 8

Step-by-step explanation:

Given the data

_____Favor __Oppose__ No Opinion__Total

Demo 320___ 150 ______50 _______ 520

Repub 125___ 345 _____ 10 _________480

Total 445 ___495 ______60 ________ 1000

what is the probability that a citizen selected at random will favor reducing industries' carbon emissions, given that the person is a Republica

From the table provided :

n(favor n republican) / n(Total)

Number of republican who are in favor = 125

Total number of persons = 1000

Hence,

125 / 1000

= 1/8

Use binomial expansion to solve each exercise. (a) Find the coefficient of xy19 in (3x − 2y) 20.(b) Give a formula for the coefficient of x k in (x+1/ x) n .

Answers

9514 1404 393

Answer:

  (a) -29,884,416

  (b) C(n,(n -k)/2) . . . where C(n,k) = n!/(k!(n-k)!) and k ∈ ℕ

Step-by-step explanation:

(a) The coefficient of the k-th term of the expansion is ...

  C(20,k)(3x)^(20-k)(-2y)^k

For k=19, this is ...

  19(3x)(-2y)^19 = -29,884,416xy^19

The coefficient of the term is -29,884,416.

__

(b) The p-th term of the expansion of (x +1/x)^n is ...

  C(n,p)(x^(n-p)(1/x)^p = C(n,p)(x^(n-2p))

For some exponent k of x, the value of p will be ...

  k = n -2p

  p = (n -k)/2

Then the coefficient of x^k will be C(n, (n-k)/2), where C(n, x) = n!/(x!(n-x)!).

You will notice that there will only be a term x^k for k having the same parity as n.

write the equation in slope-intercept form of the line that passes through (6,-11) and is parallel to the graph of y=-2/3x+12

Answers

Answer:

[tex]y = -\frac{2}{3}x - 7[/tex]

Step-by-step explanation:

Given

[tex]Point = (6,-11)[/tex]

[tex]Equation: y = -\frac{2}{3}x + 12[/tex]

Required

Determine the equation of the point

First, we need to determine the slope of the point.

Since the point is parallel to the given equation, then they have the same  slope (m).

The general form of an equation is:

[tex]y = mx + b[/tex]

Where

[tex]m = slope[/tex]

By comparison:

[tex]m = -\frac{2}{3}[/tex]

The equation of the point in slope intercept point is:

[tex]y -y_1 = m(x-x_1)[/tex]

Where

[tex]m = -\frac{2}{3}[/tex]

[tex](x_1,y_1) = (6,-11)[/tex]

Substitute these values in the equation:

[tex]y - (-11) = -\frac{2}{3}(x - 6)[/tex]

[tex]y +11 = -\frac{2}{3}(x - 6)[/tex]

[tex]y +11 = -\frac{2}{3}x + \frac{2}{3}*6[/tex]

[tex]y +11 = -\frac{2}{3}x + 4[/tex]

Subtract 11 from both sides

[tex]y = -\frac{2}{3}x + 4-11[/tex]

[tex]y = -\frac{2}{3}x - 7[/tex]

Enter your answer in the answer box and then click Check Answer.
All parts showing

Answers

Answer: The height of the building = 14.5 feet.

Step-by-step explanation:

Given: Length of ladder = 15 feet

Distance of base of ladder from building = 4 feet

Since building is standing vertical on ground making right angle.

So with ladder a right triangle is formed , where base = 4 feet , Hypotenuse = 15 feet [Hypotenuse is side opposite to right angle]

According to the Pythagoras theorem ,

Hypotenuse² = Perpendicular² + Base²

⇒ (15)² =  Perpendicular² +  (4)²

⇒ 225 = Perpendicular² +16

⇒ Perpendicular² = 225 -16

⇒ Perpendicular² = 209

⇒  Perpendicular = √209 = 14.4568322948 ≈ 14.5 feet

Hence, the height of the building = 14.5 feet.

Consider the composite function g(F(x)) = x square root of 6.
If f(x) = 3x2, what is g(x)?


Answers

Answer:

g(x) = √(2x)

Step-by-step explanation:

f(x) = 3x^2

g(f(x)) =√6x

g(3x^2) = x√6

g(x) must be √(2x)

because if we  substitute  x = 3x^2 in this we get

(√2(3x^2))

= √2√3√(x^2)
