Can someone help I’m so confused

Answer:

35 times, or D

Step-by-step explanation:

A bag contains 5 red marbles, 6 blue marbles, 3 green marbles, 4 black marbles, and 2 yellow marbles. A marble will be drawn from the bag and replaced 100 times. What is a reasonable prediction for the number of times a green or black marble will be drawn?

A quick lesson on probability:

The probability of an event is: (the number of ways what you want can happen) / (total number of outcomes possible). For example, in a coin flip, there is 1 way to get heads, and 2 possible outcomes. Thus, the possiblity  of flipping a coin and getting heads is:

(1 way to get heads) / (2 possible outcomes) = 1/2

Then, if we were to flip the coin 100 times, we would expect about 1/2 of the times to be heads, so we should expect heads 50 times.  

On to the problem.

There are 3 green marbles and 4 black marbles, so there are 7 ways to draw a green or black marble.

Then, there are 5 + 6 + 3 + 4 + 2 = 20 possible outcomes.

Using the formula to find the probability, substitute the values we just found.

(the number of ways what you want can happen) / (total number of outcomes possible) =

(7 ways to draw a green or black marble) / (20 marbles that can be drawn) = 7/20 chance of getting a green or black marble.

Then, because there is a 7/20 chance of getting what we want, and there are 100 draws, we can say that an we should get green or black

7/20 * 100 = 35 times, or D

Answer:

6.16 miles

Step-by-step explanation:

When solving word problems like these, I like to start by drawing a picture.

So, Glera starts at her home and moves north by 5.8 miles. Then, she walks west by 2.1 miles to the library. The problem wants you to find the distance from her home to the library.

I've attached a drawing I made to help me visualize the problem. The distance from her home to the library is the hypotenuse of the triangle. To solve for it, you would use the equation [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex].

a and b are the sides of the triangle, and c is the hypotenuse.

[tex]5.8^{2}[/tex]  + [tex]2.1^{2}[/tex] = [tex]c^{2}[/tex]

33.64 + 4.41 = [tex]c^{2}[/tex]

38.05 = [tex]c^{2}[/tex]

To find c, you would take the square root of 38.05, which is about 6.16 if you use a calculator.

So, the distance from her home to the library is 6.16 miles!

Answer:

  y ≥ 1/4x + 2

Step-by-step explanation:

The line is solid, and the shading is above it, so the inequality will have a form similar to ...

  y ≥ [the boundary line]

The y-intercept is y = 2, and the slope is 1 unit up for 4 units right, so 1/4. In slope-intercept form, the equation of the boundary line is ...

  y = mx + b . . . . . . for slope m and y-intercept b

This boundary line has equation ...

  y = 1/4x + 2

So, the inequality is ...

  y ≥ 1/4x + 2

The comparison of the given function and the graph is required.

It is true that y-intercept of both functions is 0.

It is false that the slope of both functions is [tex]\dfrac{3}{2}[/tex]

It is true that the graphs function has a greater rate of change.

It is true that point (0,0) is the point of intersection for both the functions.

Two points of the graph are (0,0),(-2,-3).

The equation of the line is

[tex]y-0=\dfrac{-3}{-2}(x-0)\\\Rightarrow y=\dfrac{3}{2}x[/tex]

The other equation is [tex]y=\dfrac{2}{3}x[/tex]

Both the lines pass through the origin so the y intercept of both the functions is 0.

Only the slope of the function in the graph is [tex]\dfrac{3}{2}[/tex] the other function has slope [tex]\dfrac{2}{3}[/tex]

Writing the decimal forms of the slopes [tex]\dfrac{3}{2}=1.5[/tex] and [tex]\dfrac{2}{3}=0.67[/tex]

The function in the graph does have a greater rate of change.
