The probability of choosing a red marble is:

Answer:

1 : 8

Step-by-step explanation:

Given the height of 2 similar cylinders = a : b , then

ratio of volumes = a³ : b³

Here the ratio of heights = 1 : 2

ratio of volumes = 1³ : 2³ = 1 : 8

Answer:

x   y

0  .75

3  3.75

9  9.75

Step-by-step explanation:

You add .75 to whatever number x equals, to get y.

Hope that this helps!

Ok, this is a bit tricky, it might be A or D.

Step-by-step explanation:

First i found the area of the triangle, .5(10*7)=35

And the area of a circle formula is pi*r^2 so...

35-(pi*2.8^2)=35-24.6300864=10.3699136

Answer:

Cos <B = 3/5

Step-by-step explanation:

Find the diagram attached

From the diagram, we have;

Hypotenuse BC = 80

Opposite to <B = AC =64

Adjacent AB = 48

According to SOH CAH TOA identity

Cos theta = adjacent/hypotenuse

Cos<B = AB/BC

Cos <B = 48/80

Express in its simplest form

Cos <B = (16*3)/(16*5)

Cos <B = 3/5

Hence the ratio of cos<B in its simplest form is 3/5

Answer: [tex]84\ \text{units}[/tex]

Step-by-step explanation:

Given

The length of each cube is [tex]a=14\ \text{units}[/tex]

If there are 6 cubes placed over each other, then the height achieved by the cubes is

[tex]\Rightarrow 6\times 14\\\Rightarrow 84\ \text{units}[/tex]

Answer:

Only f(x) has an x-intercept.

All three functions have the same domain values.

Step-by-step explanation:

Given

See attachment for table

Required

Select two correct options

Checking the domain:

The x values represent the domain.

From the attached table, we have:

[tex]x = \{-4.-3,-2,-1,1\}[/tex]

These values of x apply to the three functions; f(x), g(x) and h(x).

This means that the functions have the same domain

Checking the greatest maximum

The maximum of each function is:

[tex]f(x) = 1[/tex]

[tex]g(x) = -4[/tex]

[tex]h(x) = 2[/tex]

Compare these three values, we have:

[tex]h(x) > f(x) > g(x)[/tex]

This means that h(x) has the greatest maximum

Checking the x intercept

When a function equals 0, then it has an x intercept

Of the three functions, we have:

[tex]f(-3) = 0[/tex] --- This represents the x intercept.

Other functions do not have this value.

This means that only f(x) has an x intercept

Answer:

Only f(x) has an x-intercept.

All three functions have the same domain values.

Answer:

The first aid station is at the middle of the park.

Step-by-step explanation:

Given

[tex](0,0) \to[/tex] Origin of Fun

[tex](-7, 6) \to[/tex] Quadratics in Motion

[tex](-2, 14) \to[/tex]Towers of Trigonometry

[tex](5,8) \to[/tex] The Food Equation

[tex](-1,7)\to[/tex] First aid station

Solving (a): Plot the above points

See attachment for plot

Solving (b): Determine if the first aid station is at the center of the park

From the plot, we have the opposite points to be:

(1) [tex](0,0)[/tex] and  [tex](-2, 14)[/tex]

(2) [tex](5,8)[/tex]  and [tex](-7, 6)[/tex]

Calculate midpoint using:

[tex]M = \frac{1}{2}(x_1 + x_2, y_1 + y_2)[/tex]

For (1):

[tex]M = \frac{1}{2}(0 -2, 0 + 14)[/tex]

[tex]M = \frac{1}{2}(-2,14)[/tex]

[tex]M = (-1,7)[/tex]

For (2):

[tex]M = \frac{1}{2}(5 -7, 8 + 6)[/tex]

[tex]M = \frac{1}{2}(-2,14)[/tex]

[tex]M = (-1,7)[/tex]

From the above computation, we have midpoint to be:

[tex]M = (-1,7)[/tex]

Given that:

[tex](-1,7)\to[/tex] First aid station

We can conclude that the first aid station is at the middle of the park.

Answer:

A B D

Step-by-step explanation:

those are the answers

But a closer look shows that B will be the best answer.

Answer:

Since all the rhombus is parallelogram

some are trapezoid and quadrilateral.

So

B.parallelogram is a answer:

it opposite side are equal.

Answer:

A

Step-by-step explanation:

The third pair of cleats shows the marginal cost is [tex]\$1[/tex]. Thus option (C) is the correct answer.

"A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. The points on the graph often represent the relationship between two or more things".

For the given situation,

The graph is plotted between the production of pair of cleats to the marginal cost.

The first pair of cleats shows the marginal cost is from [tex]\$2[/tex] to [tex]\$7[/tex].

The second pair of cleats shows the marginal cost is from [tex]\$2[/tex] to [tex]\$1[/tex].

The third pair of cleats shows the marginal cost is [tex]\$1[/tex].

The fourth pair of cleats shows the marginal cost is from [tex]\$4[/tex] to [tex]\$6[/tex].

Hence from the given data, the third pair of cleats shows the marginal cost is [tex]\$1[/tex]. Thus option (C) is the correct answer.

Step-by-step explanation:

Answer:

7.3

Step-by-step explanation:

The system of equations that represents the number of each type of basket Jake scored is given by:

x + y = 13

2x + 3y = 28

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

Jake scored 28 points in his basketball game by shooting only two-point and three-point shots, hence:

2x + 3y = 28.

He scored a total of 13 baskets, hence:

x + y = 13.
