I think A or D but i'm stuck on D

Step-by-step explanation:

Answer:

D because if you multiply all the other brands to get a 100oz they are more expensive/ high than D.

Answer:

The value of P(B) = 0.5

Step-by-step explanation:

Given:

Value of P(A and B) = 0.20

Value of P(A|B) = 0.40

Find:

The value of P(B)

Computation:

P(A and B) = P(A|B) x P(B)

By putting value of P(A and B)  and P(A|B)

⇒ 0.20 = 0.40 x P(B)

⇒ The value of P(B) = 0.20 / 0.40

⇒ The value of P(B) = 20 / 40

⇒ The value of P(B) = 1 / 2

The value of P(B) = 0.5

Answer:

I don't know D

Step-by-step explanation:

but why is this in the mathematics section

Answer:

B

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 3 , then

y = 3x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation.

Using (4, 10 ) , then

10 = 12 + c ⇒ c = 10 - 12 = - 2 → B

D

Given m = 4 then

y = 4x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (3, 19 ), then

19 = 12 + c ⇒ c = 19 - 12 = 7 → D

Answer:

collection of information

Step-by-step explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.

Pseudoscience can be defined as a collection of theories, methodology, practices and beliefs about the universe that are mistakenly, purportedly or erroneously regarded as scientific but in true sense isn't backed up by evidence (facts) and fails to comply with any scientific model.

However, a common characteristic of both science and pseudoscience is that both fields deals with the collection of information.

In conclusion, pseudoscience is considered to be subjective while science is objective.

We can predict the outcome of the second set of trials by assuming that the ratio will be the same as in the first set of trials. Write a proportion by setting the two ratios equal to each other, then solve.

Answer:

the correct answer is -6

Answer:

d)-6

Step-by-step explanation:

negative and positive is a negative in multiplication. and 6x6=36

so if you put 6(-6) you get -36

Answer:

2 1/4

Step-by-step explanation:

SOL Review question 4

Adana made key chains for her friends out of string.  She started with 2 1/6  feet of red string, 3 1/4 of yellow string, and 5 1/2 feet of green string. If Adana used a total of 8 2/3 feed of string on the key chains, How much string remains unused.

It would be 2 1/4 because you convert all the factions denominators to 12. 2 1/6 becomes 2 2/12, 3 1/4 becomes 3 3/12, 5 1/2 becomes 5 6/12, and 6 2/3 becomes 8 8/12. add 2 2/12, 3 3/12, and 5 6/12 and you get 10 11/12 and then you subtract 10 11/12 and 8 8/12 (10 11/12 - 8 8/12) and get 2 3/12. when you get that answer, convert it by 3 and you get 2 1/4.

I hope this was helpful.

Answer:

  (b)  80°

Step-by-step explanation:

The relevant trig relation is ...

  Cos = Adjacent/Hypotenuse

The 1.5 meter distance to the wall is the side adjacent to the angle with the ground. The 9 m length of the ladder is the hypotenuse of the triangle modeling this situation.

  cos(angle) = 1.5/9 = 1/6

  angle = arccos(1/6) ≈ 80.4°

The angle between the ladder and the ground is about 80°.

_____

Additional comment

The Ladder Association recommends an angle of 75° for safety. At 80°, the ladder may have a tendency to tip the user backward.

Answer:

Elisa y Romina comieron 5/16 de la pizza completa cada una.

Step-by-step explanation:

Dado que Elisa y Romina tienen 5/8 de pizza y decidieron dividírsela en partes iguales, para determinar qué parte de la pizza completa le tocó a cada una se debe realizar el siguiente calculo:

(5/2) / 8 = X

2.5 / 8 = X

0.3125 = X

0.3125 = 5/16

Por lo tanto, Elisa y Romina comieron 5/16 de la pizza completa cada una.

Answer:

8(6x + 7)

Step-by-step explanation:

Find a factor for both of the numbers (8)

Place the remaining numbers in a bracket (6x +7)

Place the 8 outside the bracket

8 (6x + 7)

Have a good day :)

Answer:

All you have to do is factor like this. It is also know as common factoring.

48x+54

8(6x+7)  You chose the eight because it fits into 48 and 54. So you find the multiple of 8 to get the total of 48. And that is 6 and for 54 it would turn out to be 7. So the answer would be  8(6x+7)

Answer:

Rectangular route

Step-by-step explanation:

Given

H(-4, 3)    B (2, 11)   F (6, 8)   C (0, 0)

Required

The type of route

First, calculate the distance between adjacent points i.e. HB, BF, FC and CH

Where

HB and FC are opposite

BF and CH are opposite

Using distance formula:

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

So, we have:

HB

[tex]H =(-4, 3) \to (x_1,y_1)[/tex]

[tex]B = (2, 11) \to (x_2,y_2)[/tex]

[tex]HB = \sqrt{(-4- 2)^2 + (3 -11)^2}= \sqrt{(-6)^2 + (-8)^2} = \sqrt{36 + 64} = \sqrt{100} = 10[/tex]

BF

[tex]B = (2, 11) \to (x_1,y_1)[/tex]

[tex]F = (6, 8) \to (x_2,y_2)[/tex]

[tex]BF = \sqrt{(2- 6)^2 + (11 -8)^2}= \sqrt{(-4)^2 + (3)^2} = \sqrt{16 + 9} = \sqrt{25} = 5[/tex]

FC

[tex]F = (6, 8) \to (x_1,y_1)[/tex]

[tex]C =(0, 0) \to (x_2,y_2)[/tex]

[tex]FC = \sqrt{(6- 0)^2 + (8 -0)^2}= \sqrt{(6)^2 + (8)^2} = \sqrt{36 + 64} = \sqrt{100} = 10[/tex]

CH

[tex]C =(0, 0) \to (x_1,y_1)[/tex]

[tex]H =(-4, 3) \to (x_2,y_2)[/tex]

[tex]CH = \sqrt{(0-- 4)^2 + (0 -3)^2}= \sqrt{(4)^2 + (-3)^2} = \sqrt{16 + 9} = \sqrt{25} = 5[/tex]

So, we have:

[tex]HB = FC = 10[/tex]

[tex]BF = CF = 5[/tex]

Sine the opposite sides are equal; We can conclude that the route is a rectangle

Answer:

f(g(x)) = 8x² + 18x - 8

Step-by-step explanation:

Substitute x = g(x) into f(x) , that is

f(g(x))

= f(- 2x - 1)

= 2(- 2x - 1)² - 5(- 2x - 1) - 15

= 2(4x² + 4x + 1) + 10x + 5 - 15

= 8x² + 8x + 2 + 10x - 10

= 8x² + 18x - 8
