A game of chance involves rolling a 16-sided die once. If a number from 1 to 3 comes up, you win 4 dollars. If the number 4 or 5 comes up, you win 7 dollars. If any other number comes up, you lose. If it costs 5 dollars to play, what is your expected net winnings

Answer:

A

Step-by-step explanation:

The value of x + y for the given system of equations is found to be as 5.

A system of linear equations is a group of  equations having same number of variables and degree.

For the n number of variables n number of equations are required.

On the basis of number of solutions a system of equations can be classified as consistent and inconsistent.

The given equations are as follows,

x + 7y = 23                      (1)

3x + 14y = 48                  (2)

Solve the equations by substituting the value of x from equation (1) into (2) as follows,

3x + 14y = 48

=> 3(23 - 7y) + 14y = 48

=> -21y + 14y = 48 - 69

=> -7y = -21

=> y = 3

Then, x = 23 - 7y = 23 - 7 × 3 = 2

Thus, the value of x + y is given as 3 + 2 = 5.

Hence, the value of the required expression is given as 5.

Step-by-step explanation:

Answer:

Mean: [tex]20.2[/tex], Median: [tex]20[/tex], Mode: [tex]18[/tex]

Step-by-step explanation:

The mean or average of a data set is calculating by dividing the sum of the data values by the number of the data values. In this case, the sum of the data values is [tex]18+24+20+18+21=101[/tex] and the number of data values is [tex]5[/tex], so the mean is [tex]\frac{101}{5}=20.2[/tex].

The median of a data set is the middle value when the data is ordered in ascending order, meaning least to greatest. Right now, the data is not in ascending order, but after ordering it, we get [tex]18,18,20,21,24[/tex]. Since there are [tex]5[/tex] data values in this set, the middle value, or median, will be the [tex]3[/tex]rd value, which, in this case, is [tex]20[/tex].

Finally, the mode of a data set is the most frequent value, or the value that shows up the most. In this case, [tex]18[/tex] shows up twice, unlike the other numbers, which only show up once, so we know that the mode is [tex]18[/tex]. Hope this helps!

Answer:

[tex]sec\ x = \frac{25}{24}[/tex]

Step-by-step explanation:

Given

[tex]sin\ x = -\frac{7}{25}[/tex]

[tex]cot\ x = -\frac{24}{7}[/tex]

Required

Determine sec x

Sec x is calculated as:

[tex]sec\ x = \frac{1}{cos\ x}[/tex]

Multiply by sin x/sin x

[tex]sec\ x = \frac{1}{cos\ x} * \frac{sin\ x}{sin\ x}[/tex]

[tex]sec\ x = \frac{1}{sin\ x} * \frac{sin\ x}{cos\ x}[/tex]

[tex]sec\ x = \frac{1}{sin\ x} * \tan\ x[/tex]

[tex]tan\ x = \frac{1}{cot\ x}[/tex]

[tex]sec\ x = \frac{1}{sin\ x} * \frac{1}{cot\ x}[/tex]

The equation becomes:

[tex]sec\ x = \frac{1}{-7/25} * \frac{1}{-24/7}[/tex]

[tex]sec\ x = \frac{-25}{7} * \frac{-7}{24}[/tex]

[tex]sec\ x = \frac{25}{24}[/tex]

Answer:

[tex]zw=76 * (cos(\frac{3\pi}{16}) +isin(\frac{3\pi}{16}) )[/tex]

Step-by-step explanation:

Given

[tex]z =38 (cos(\frac{\pi}{8})+ i sin(\frac{\pi}{8})[/tex] and

[tex]w = 2 (cos(\frac{\pi}{16} ) + i sin(\frac{\pi}{16})[/tex]

Required

Determine zw

Given that:

[tex]x = v_1(cos(a) + isin(a))[/tex] and [tex]y = v_2(cos(b) + isin(b))[/tex]

[tex]x * y = (v_1 * v_2)*((cos(a+b) + isin(a+b))[/tex]

So, we have:

[tex]zw=(38 * 2) * (cos(\frac{\pi}{8} + \frac{\pi}{16}) + isin(\frac{\pi}{8} + \frac{\pi}{16}))[/tex]

[tex]zw=76 * (cos(\frac{2\pi + \pi}{16})+isin(\frac{2\pi + \pi}{16}))[/tex]

[tex]zw=76 * (cos(\frac{3\pi}{16}) +isin(\frac{3\pi}{16}) )[/tex]

The value of ZW is  [tex]\begin{aligned} (76) [Cos(\frac{3\pi}{16})+ \i\ Sin(\frac{3\pi}{16})]\end{aligned}[/tex].

Given to us,

[tex]\begin{aligned} Z &= 38 [cos(\frac{\pi}{8}) + i\ sin(\frac{\pi}{8}) ]\end{aligned}[/tex],

[tex]\begin{aligned}W &= 2 [cos(\frac{\pi}{16}) + i\ sin(\frac{\pi}{16}) ]\end{aligned}[/tex],

We know that,

[tex]{x = v_1 [ cos\ (a) +i\ sin\ (a)]}[/tex]  and  [tex]{y = v_2 [ cos(b) +i\ sin(b)]}[/tex]

So,

[tex]xy = (v_1 \times v_2) [ cos(a+b) + i\ sin(a+b)][/tex]

Therefore, we can write it as,

[tex]\begin{aligned}ZW &= [38cos(\frac{\pi}{8}) + 38\ i\ sin(\frac{\pi}{8}) ]\times [2cos(\frac{\pi}{16}) + 2\ i\ sin(\frac{\pi}{16}) ]\\&= (38 \times 2) \{Cos[\frac{\pi}{8} + \frac{\pi}{16}]\}+ \{i\ Sin[\frac{\pi}{8} + \frac{\pi}{16}]\} \end{aligned}[/tex]

        [tex]\begin{aligned}&= (76) [Cos(\frac{3\pi}{16})+ \i\ Sin(\frac{3\pi}{16})]\end{aligned}[/tex]

Hence, the value of ZW is  [tex]\begin{aligned} (76) [Cos(\frac{3\pi}{16})+ \i\ Sin(\frac{3\pi}{16})]\end{aligned}[/tex].

Answer: 105m²

Formula for Area of Circle: A = π r²

so, A = 3.14 (6)² (I got 6 because radius is half the diameter)

Don't forget to divide the final area of the circle in half, because It's only a semicircle.

Formula for Triangle: A = [tex]\frac{bh}{2\\}[/tex]

so, A = [tex]\frac{6(8)}{2}[/tex] (again, the "6" is just the diameter divided in half which forms the base of ONE triangle.)

You need to multiply the final area of the triangle by 2 since there are 2 triangles.
