A) Bill's chances are the same as Sandra's chances.

B) Since she is on a streak, Sandra's chances are higher.

C) Since he hasn't been rolling them, Bill's chances are higher.

D) It depends on whether or not the dice are fair.

Answer:

Step-by-step explanation:

The answer is D. I just did it.

Answer:

Option D.

Step-by-step explanation:

We have to solve the trigonometric expression give below.

[tex]tan(x+\frac{\pi }{3})[/tex]

[tex]=\frac{tanx+tan\frac{\pi }{3}}{1-tanx.tan\frac{\pi }{3}}[/tex]

[Since [tex]tan(a+b)=\frac{tana+tanb}{1-tana.tanb}[/tex]]

Now we place the value of [tex]tan\frac{\pi }{3}=\sqrt{3}[/tex]

[tex]=\frac{tanx+\sqrt{3}}{1-tanx\sqrt{3}}[/tex]

Therefore, option D. is the answer.

The probability that the die will land with a value less than 3 and on a red square, given an equal number of black and red squares, is 1/6.

The subject of this question is probability, a branch of Mathematics. In the given scenario, Gabrielle is tossing a die onto a black-and-red checkerboard. There are two separate events here - the roll of the die and the colour of the square where the die lands.

Firstly, the probability that the die will land with a value less than 3 is 2/6, or 1/3, as there are two sides of a six-sided die that have values less than 3 (1 and 2).

Secondly, assuming the checkerboard has an equal number of red and black squares, the probability that the die will land on a red square is 1/2.

Since these are separate events, we can calculate the combined probability by multiplying the probabilities of the individual events: (1/3) * (1/2) = 1/6. So, the answer is 1/6.

Answer:

The graph is symmetric about the x-axis only

Step-by-step explanation:

* Lets study the limacon curve

- Equations of the form:

# r = a + b sin θ

# r = a – b sin θ

# r = a + b cos θ

# r = a – b cos θ  

All will produce limacons.    

* Lets examine what happens for various values of a and b.  

- When the value of a is less than the value of b, the graph is  

 a limacon with and inner loop.

- When the value of a is greater than the value of b, the graph is

 a dimpled limacon.

- When the value of a is greater than or equal to the value of 2b,  

 the graph is a convex limacon.

- When the value of a equals the value of b, the graph is a special  

 case of the limacon.  It is called a cardioid.

* Notice that, in each of the graphs of the liamcons, changing

 from sine to cosine does not affect the shape of the graph just its  

 orientation.  

- Equations using sine will be symmetric to the vertical axis  

- Equations using cosine are symmetric to the horizontal axis.  

∵ r = -2 + 3 cos Ф

- from the notes up the equation of cosine is symmetric to

 the horizontal axis

∴ The graph is symmetric about the x-axis only

The volume of a cube with a side length of 1 foot is 1 cubic foot, or 1728 cubic inches. So, 1 cubic foot is equal to 1728 cubic inches. The ratios of 1 cubic inch to 1/1728 cubic foot and 1 cubic foot to 1728 cubic inches can be used to convert between cubic inches and cubic feet.

When dealing with volumes, it's crucial to understand the relationship between cubic feet and cubic inches. Since 1 foot is equivalent to 12 inches, 1 cubic foot contains 12 × 12 × 12 = 1728 cubic inches. This conversion factor arises because volume is a measure of three-dimensional space, so each dimension is multiplied by itself three times.

To convert between cubic feet and cubic inches, you can use the conversion factor: 1 cubic foot = 1728 cubic inches. This means that to convert cubic feet to cubic inches, you multiply the volume in cubic feet by 1728, and to convert cubic inches to cubic feet, you divide the volume in cubic inches by 1728.

Understanding this relationship allows for easy conversion between the two units, whether you're dealing with measurements in feet or inches.

The probable question may be:

The volume of a cube with a side length of 1 foot is __ cubic foot, or __ cubic inches. So, 1 cubic foot is equal to __ cubic inches. The ratios of __ cubic inches to __ cublc foot and __ cubic foot to __ cubic inches can be used to convert between cubic inches and cubic feet.

Answer:

two solutions x = 1 and x = - 8/3 x

Step-by-step explanation:

These are two questions and two answers:

Question 1:

A quadratic equation is shown below: 3x^2 − 15x + 20 = 0 Part A: Describe the solution(s) to the equation by just determining the radicand. Show your work.

Answer: The negative value of the radicand means that the equation does not have real solutions.

Explanation:

1) With radicand the statement means the disciminant of the quadratic function.

2) The discriminant is: b² - 4ac, where a, b, and c are the coefficients of the quadratic equation: ax² + bx + c

3) Then, for 3x² - 15x + 20, a = 3, b = - 15, and c = 20

and the discriminant (radicand) is: (-15)² - 4(3)(20) = 225 - 240 = - 15.

4) The negative value of the radicand means that the equation does not have real solutions.

Question 2:

Part B: Solve 3x^2 + 5x − 8 = 0 by using an appropriate method. Show the steps of your work, and explain why you chose the method used.

Answer: two solutions x = 1 and x = - 8/3x

Explanation:

1) I choose factoring (you may use the quadratic formula if you prefer)

2) Factoring

Given: 3x² + 5x − 8 = 0

Make 5x = 8x - 3x: 3x² + 8x - 3x - 8 = 0

Group: (3x² - 3x) + (8x - 8) = 0

Common factors for each group: 3x(x -1) + 8(x - 1) = 0

Coomon factor x - 1: (x - 1) (3x + 8) = 0

The two solutions are for each factor equal to zero:

x - 1 = 0 ⇒ x = 1

3x + 8 = 0 ⇒ x = -8/3

Those are the two solutions. x = 1 and x = - 8/3

There's no string in your question so zero. If you find out how long the string is just subtract it from the ribbon

Step-by-step explanation:

Answer:

It is A.

Step-by-step explanation:

In function A we see that there are 2 ordered pairs with value 2 in the first position with y values 6 and 2. So this is not a function.

A function is a relation in which each input pairs with exactly one output. In the given relations, option A is not a function because the input 2 pairs with both 6 and 2, contradicting the definition of a function.

In mathematics, a function is a relation in which every input, also known as the domain, corresponds to exactly one output, called the range. Looking at the following relations, we determine if a relation is not a function by seeing if any input values are paired with more than one output.

Option A: {(2, 6), (- 4, 0), (2, 2), (3, 5)} is NOT a function because the input 2 corresponds to both 6 and 2, which violates the definition of a function.

Options B, C, and D each pair every input with exactly one output, thus they are all functions. In conclusion, the relation provided in option A is the only one that is not a function.

Answer:

x = [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Using the rules of logarithms

• log[tex]x^{n}[/tex] ⇔ n logx

• logx - logy = log([tex]\frac{x}{y}[/tex])

• logx = logy ⇔ x = y

Given

2log2 - 3log2 = log2x

log2² - log2³ = log2x

log4 - log8 = log2x

log[tex]\frac{4}{8}[/tex] = log2x, hence

2x = [tex]\frac{1}{2}[/tex]

x = [tex]\frac{1}{4}[/tex]

For this case it is observed that the border of the region is not dotted, then the inequality includes an equal.

Thus, we discard options C and D.

We substitute the point (0,0) and see if it is fulfilled:

[tex]y\geq\frac {3} {2} x-3\\0 \geq\frac {3} {2} (0) -3\\0 \geq0-3\\0 \geq-3[/tex]

It is fulfilled, so the correct option is A.

Answer:

Option A

Answer:

A. [tex]y\geq \frac{3}{2} x-3[/tex]

Step-by-step explanation:

We are given a graph and we are to determine which inequality is described by the graph.

Since the graph has a solid line that means that the inequality includes the points on the line and must contain an equal sign.

So we will substitute the point (0, 0) to find the correct inequality.

[tex]y\geq \frac{3}{2} x-3[/tex]

[tex]0\geq \frac{3}{2} (0)-3[/tex]

[tex]0\geq 3[/tex] - true

[tex]y\leq \frac{3}{2} x-3[/tex]

[tex]0\leq \frac{3}{2} (0)-3[/tex]

[tex]0\leq 3[/tex] - false

Therefore, the correct inequality is [tex]y\geq \frac{3}{2} x-3[/tex].

Answer:

according to the equation it is 158.330917...

Step-by-step explanation:

put w as 64 and solve for t

Answer: 158.331 minutes.

Step-by-step explanation: To solve this problem we need to replace the given level of water (64 cups) in the equation, and isolate and calculate the time (t):

W=-0.414t+129.549

isolating t:

W-129.549=-0.414t

t=(W-129.549)/-0.414

replacing W=64

t=(64-129.549)/-0.414

t=-65.549/-0.414

t=158.331 minutes.

Answer:

Choice C: approximately 121 green beans will be 13 centimeters or shorter.

Step-by-step explanation:

What's the probability that a green bean from this sale is shorter than 13 centimeters?

Let the length of a green bean be [tex]X[/tex] centimeters.

[tex]X[/tex] follows a normal distribution with

In other words,

[tex]X\sim \text{N}(11.2, 2.1^{2})[/tex],

and the probability in question is [tex]X \le 13[/tex].

Z-score table approach:

Find the z-score of this measurement:

[tex]\displaystyle z= \frac{x-\mu}{\sigma} = \frac{13-11.2}{2.1} = 0.857143[/tex]. Closest to 0.86.

Look up the z-score in a table. Keep in mind that entries on a typical z-score table gives the probability of the left tail, which is the chance that [tex]Z[/tex] will be less than or equal to the z-score in question. (In case the question is asking for the probability that [tex]Z[/tex] is greater than the z-score, subtract the value from table from 1.)

[tex]P(X\le 13) = P(Z \le 0.857143) \approx 0.8051[/tex].

"Technology" Approach

Depending on the manufacturer, the steps generally include:

For example, on a Texas Instruments TI-84, evaluating [tex]\text{normalcdf})(-1\text{E}99,\;13,\;11.2,\;2.1 )[/tex] gives [tex]0.804317[/tex].

As a result,

[tex]P(X\le 13) = 0.804317[/tex].

Number of green beans that are shorter than 13 centimeters:

Assume that the length of green beans for sale are independent of each other. The probability that each green bean is shorter than 13 centimeters is constant. As a result, the number of green beans out of 150 that are shorter than 13 centimeters follow a binomial distribution.

Let [tex]Y[/tex] be the number of green beans out of this 150 that are shorter than 13 centimeters. [tex]Y\sim\text{B}(150,0.804317)[/tex].

The expected value of a binomial random variable is the product of the number of trials and the probability of success on each trial. In other words,

[tex]E(Y) = n\cdot p = 150 \times 0.804317 = 120.648\approx 121[/tex]

The expected number of green beans out of this 150 that are shorter than 13 centimeters will thus be approximately 121.

h(x) passes through (-1,4) and (1,2)

b)  q(x) = | x | + 3

|-1| + 3 = 4

| 1 | + 3 = 4

q(x) passes through (-1,4) and (1,4)

c) w(x)  = | x+ 3 |

| -1 + 3 | = | 2 | = 2

| 1 + 3 | = | 4 | = 4

w(x) passes through (-1,2) and (1,4)

Answer:

Option D) multiply y by 4 in the first equation and subtract the second equation

Step-by-step explanation:

we have

2x+y=-10 ----> first equation

3x+4y=-20 ---> second equation

Verify each case

case A) multiply the first equation by 4 and subtract the second equation

so

(2x+y)*4=-10*4 ------> 8x+4y=-40

[8x+4y=-40]-[3x+4y=-20] -----> 5x=-20 -----> x=-4

This step is correct

case B) multiply the first equation by -4 and add the second equation

so

(2x+y)*-4=-10*-4 ------> -8x-4y=40

[-8x-4y=40]+[3x+4y=-20] ----->-5x=20 -----> x=-4

This step is correct

case C)  add 8 times the first equation and −2 times the second equation

so

(2x+y)*8=-10*8 ------> 16x+8y=-80

(3x+4y)*-2=-20*-2 ----> -6x-8y=40

[16x+8y=-80]+[-6x-8y=40] ----->10x=-40 -----> x=-4

This step is correct

case D) multiply y by 4 in the first equation and subtract the second equation

so

2x+4y=-10

[2x+4y=-10]-[3x+4y=-20] -----> -x=-10+20 -----> x=-10

This step is incorrect

NOT produce a system with the same solution

Answer:

the answer is he rode 17 miles in the morning and 40 miles in the afternoon

Step-by-step explanation:

so in the afternoon, it says that 6 more than twice as many miles in the afternoon as in the morning. this means that if the morning is x then in the afternoon it will be 2x+6 but it says altogether it is 57 miles so the you have to add x too.

so the equation is 2x+6+x=57

then this should be easy to solve.

2x+6+x=57

3x+6=57

3x=51

x=17

so if the morning is 17 miles then the afternoon will be:

2(17)+6

this equals to 40.
