Step-by-step explanation:

Total marbles = 12 + 30 + 20 + 10 + 8 = 80

Probability = 12 + 30 + 8 = 50

= 50 / 80 = 5 / 8

Answer:

15 ft

Step-by-step explanation: To solve this, you have to use the Pythagorean Theorem. The 25 ft is the hypotenuse, the longest side of the triangle. the building's height, 20 ft is one of the legs. The missing measurement is one of the other legs.

Pythagorean Theorem: A^2 + B^2 = C^2

A and B are legs and C is the hypotenuse.

Substitute the values:

20^2 + B^2 = 25^2

400+ B^2 = 625

625 - 400 = 225

225 = 15^2

Answer:

1/5

Step-by-step explanation:

There are 10 marbles in the jar (2+8 = 10)

P(pink) = number of pink marbles / total marble

           = 2/10 = 1/5

Answer:

1/5 or 20% because there is ten marbles and there is 2 pink so the theoretical answer is 20% or 1/5

Answer:

y = - 8x² + 6

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (0, 6), thus

y = a(x - 0)² + 6, that is

y = ax² + 6

To find a substitute (- 1, - 2) into the equation

- 2 = a(- 1)² + 6, that is

- 2 = a + 6 ( subtract 6 from both sides )

- 8 = a

y = - 8x² + 6

The formula of the quadratic function is [tex]y = -8x^2 + 6[/tex]

A quadratic function is represented as:

[tex]y = a(x - h)^2 + k[/tex]

The vertex of the quadratic function is given as:

[tex](h,k) = (0,6)[/tex]

So, we have:

[tex]y = a(x - 0)^2 + 6[/tex]

This gives:

[tex]y = ax^2 + 6[/tex]

The quadratic function passes through (-1,-2).

So, we have:

[tex]-2 = a(-1)^2 + 6[/tex]

[tex]-2 = a + 6[/tex]

Subtract 6 from both sides

[tex]a = -8[/tex]

Substitute -8 for a in [tex]y = ax^2 + 6[/tex]

[tex]y = -8x^2 + 6[/tex]

Hence, the formula of the quadratic function is [tex]y = -8x^2 + 6[/tex]

hope this helps :)

Kind of need a picture to help answer the question.

Hey there! I'm happy to help you! :)

We see that there are 160 songs in total. Let's split them up into groups of rock, country, and pop.

ROCK

Our problem says that 3/8 of the songs are rock songs. We know that we have 160 songs. We just need to multiply 3/8 by 160 and we will have the number of rock songs.

3/8*160=60

Therefore, we have 60 rock songs.

COUNTRY

We see that 25% of our songs are country songs. 25% is the same thing as 1/4, or 0.25. We can multiply this by our total number of songs to see how many are country.

0.25(160)= 40

We have 40 country songs.

POP

All we have in the problem is that the remaining songs are pop. The nice thing is is that we already know how many rock and country songs we have, so we can simply subtract those from 160 and we will then be able to tell how many pop songs there are.

160-60-40= 60

Therefore, there are 60 pop songs.

I hope that this helps you! Have a wonderful day!

The interval over which the function f(x) is negative is (-infinity, -4) .

Given,

The values of f(x) for corresponding x .

Here,

From the table,

x = -8 ; f(x) = -16

x = -6 ; f(x) = -8

Thus from the data given in the table it is clear that the function f(x) will be negative if we decrease the value of x .

Thus f(x) will be negative for the values which are smaller than -8 .

Now,

When

x = -4 ; f(x) = 0

x = -2 ; f(x) = 8

Thus f(x) changes its sign at x = -4.

So,

Interval in which f(x)  will be negative : (-infinity, -4) .

Answer:

Step-by-step explanation:

The answer would be -1, 0

The first numbers represent the A axis, so -3-2 = -1

The 2nd number represents the B axis, so 5-5=0

The midpoint of the line segment is (-1/2, 0).

The midpoint of a line segment is given as,

x = (a + c)/2

y = (b + d) / 2

Where (x, y) is the midpoint and (a, b) and (c, d) are the two endpoints.

We have,

A = (-3, -5) = (a, b)

B = (2, 5) = (c, d)

The midpoint of AB is (x, y).

x = (a + c)/2

x = (-3 + 2)/2

x = -1/2

y = (b + d) / 2

y = (-5 + 5)/2

y = 0/2

y = 0

(x, y) = (-1/2, 0)

Thus,

The midpoint is (-1/2, 0).
