Tim Has Two Spinners, Spinner A And Spinner B. Each Spinner Can Only Land On Red Or Blue. The Probability

Answers

Answer 1

Answer:

56 times

Step-by-step explanation:

To find the probability of both spinners landing on red, we need to multiply the probability of the spinner A landing on red (0.5) by the probability of the spinner B landing on red (0.6):

P(redA and redB) = 0.5 * 0.6 = 0.3

Then, to find the probability of both landing on blue, we do the same:

P(blueA and blueB) = 0.5 * 0.4 = 0.2

Now, if the number of times that both spinners land on red is 84, to estimate the number of times that both land blue, we just need to multiply this number of times by the ratio of P(blueA and blueB) over P(redA and redB):

84 * 0.2 / 0.3 = 56 times

A line goes through points (-2, 18) and (4, 3). What is the slope of the line?

A. 12

B. -1.25

C. -2.5

D. -5

Answers

Answer:

-2.5

Step-by-step explanation:

The slope can be found by

m = (y2-y1)/(x2-x1)

   = (3-18)/(4- -2)

   = -15/(4+2)

    =-15/6

    = -5/2

     -2.5

Answer:

C. -2.5

Step-by-step explanation:

Slope is: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

We are given the points (-2,18) and (4,3).

[tex]m=\frac{3-18}{4-(-2)}= \frac{-15}{6} =-\frac{15}{6}= -\frac{5}{2}[/tex]

In a circle with radius 22, an angle measuring 2\pi2π radians intercepts an arc. Find the length of the arc in simplest form.

Answers

Answer:

15

Step-by-step explanation:

The length of the arc in its simplest form will be 138.16 units.

What is the arc length of the sector?

Let r is the radius of the sector and θ be the angle subtended by the sector at the center. Then the arc length of the sector of the circle will be

Arc = (θ/2π) 2πr

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

In a circle with a radius of 22, an angle measuring 2π radians intercepts an arc.

Then the length of the arc in the simplest form will be given as,

Arc = (2π/2π) 2π (22)

Arc = 44 x 3.14

Arc = 138.16 units

The length of the arc in its simplest form will be 138.16 units.

What is the vertex of the parabola given by y = x2 − 10x + 17? A. (5, -8) B. (-5, 8) C. (5, 8) D. (-5, -8)

Answers

Answer:

A

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 ), then

The x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

y = x² - 10x + 17 ← is in standard form

with a = 1 and b = - 10, thus

[tex]x_{vertex}[/tex] = - [tex]\frac{-10}{2}[/tex] = 5

Substitute x = 5 into the equation for corresponding value of y

y = 5² - 10(5) + 17 = 25 - 50 + 17 = - 8

vertex = (5, - 8 ) → A

What is a prism?

A prism is a solid form that is enclosed by plane faces on all of its sides. A prism has two different kinds of faces. Bases refer to the identical top and bottom faces. The name "prism" refers to the form of these bases. For instance, a prism is referred to be a triangular prism if its base is triangular.

A triangular prism is a three-dimensional (3D) object having two identical triangle-shaped faces joined by three rectangular faces. The bases are the triangle faces, while the lateral faces are the rectangular faces. The top and bottom (faces) of the prism are other names for the bases.

Therefore, option B is the correct answer.

Which of these could be the value of k?
A. 0
B. 1
C. 5
D. 8

Answers

Answer:

A. 0

Step-by-step explanation:

In a function, all x-coordinates must be different.

The given function already shows 1, 2, 5, and 8 as x-coordinates, so you must choose a number other than those.

Answer: 0

The correct option will be Option A : the value of k will be 0.

What is a function?

The function is a relation between two sets where one set is called the domain and another set is the codomain which is one one or many one relations.

If the x or input values are different then the relation will become a function.

So we can say if the x values are repeated and their corresponding y or output values are the same, then also the relation becomes a function.

If the x values are repeated and their corresponding y or output values are different, then the relation will not become a function.

Given the ordered pairs are {(1,3), (2, 9), (k, 12), (5,9), (8,0)

As we know the x value is repeated and the y value is different then the relation will not be a function.

So here in the given ordered pair, there is no any second 12. So k value should not be equal to 1,2,5,8 otherwise it will not be a function.

By checking all the options

0 is not present in x value of the given ordered pair.

Therefore the correct option will be Option A : the value of k will be 0.

Answers

suplementary means adds to 180

83+b=180

minus 83 both sidse

b=97

answer is 97 degrees

Answer:

97°

Step-by-step explanation:

Supplementary angles are a pair of angles whose sum is 180°.

If one angle of a pair of supplementary angles is given, it is easy to find the other angle.

It can be found out by subtracting the given angle from 180.

So here in this case, ∠A + ∠B = 180° where ∠A = 83°

83 + ∠B = 180

∠B = 180 - 83

∠B = 97°

So the m∠B = 97°

Please help! For the function f(x) = 2x^6 + 3x^4 - 4x^3 + (1/x) - sin(2x) find the first four derivatives.

Answers

Answer:

See the explanation

Step-by-step explanation:

We know that

f(x) = 2x⁶ + 3x⁴ - 4x³ + (1/x) - sin2x

Lets calculate the derivatives:

f'(x) = 6(2x⁵) + 4(3x³) - 3(4x²) -( 1/x²) - 2(cos2x)

f'(x) = 12x⁵ + 12x³ - 12x² - (1/x²) - 2cos2x

Similarly:

f''(x) = 60x⁴ + 36x² - 24x + (2/x³) + 4sin2x

f'''(x) = 240x³ + 72x - 24 - (6/x⁴) + 8cos2x

Rearrange:

f'''(x) - 240x³ +72x - (6/x⁴) + 8cos2x - 24

f''''(x) = 720x² + 72 + (24/x⁵) - 16sin2x
