Step-by-step explanation:

    half of 100 is 50

Answer:

x=35 earbuds

Step-by-step explanation:

[tex](0,0) \longrightarrow \sf{part \: \: of \: \: the \: \: graph} \\ (1, - 3)\longrightarrow \sf{given \: \:coordinate \: \: point}[/tex]

[tex]m = \frac{dy}{dx} = \frac{y_2-y_1}{x_2-x_1}[/tex]

Substitute these coordinate values in.

[tex]m = \frac{0 - ( - 3)}{0 - 1} \\ m = \frac{3}{ - 1} \\ m = - 3[/tex]

Hence, the slope is -3.

From the graph, the line passes through the origin point. Therefore, the y-intercept is (0,0).

[tex]y = mx + b \\ \begin{cases} \sf{m = slope} \\ \sf{b = y - intercept} \end{cases}[/tex]

Substitute both m and b in the slope-intercept form.

[tex]y = - 3x + 0 \\ y = - 3x[/tex]

Hence the answer is y = -3x.

[tex] \large \boxed{y = - 3x}[/tex]

Answer:

w = 215 degrees

Step-by-step explanation:

A  circle = 360 degrees total. So, 145 + w should equal 360.

145 + w = 360

145 + w -145 = 360 - 145

w = 215

Answer:369

Step-by-step explanation:

Answer:

So the first step would be is to multiply the denominators so you would get this:

6/30 + 5/30

Then you would have 11/30 no simplification needed.

Se image below for more info:

Answer:

11/30

Step-by-step explanation:

To add fractions, you need to find the common denominators

the common denominator for 5 and 6 is 30, because 5*6 = 30

1/5 times (6/6) to get a common denominator of 30. Remember, you have to multiply the numerator by 6 too!

1           6          6

_    x    _    =    _

5         6          30

Now, we just have to multiply 1/6 by (5/5) to get a common denominator of thirty.

1           5          5

_    x    _    =    _

6         5          30

5             6         11

_     +      _    =    _

30          30        30

You final answer should be 11/30

Answer:

(9/2, 7/2)

Step-by-step explanation:

The easiest way to remember how to do this problem is to average the x-coordinates and average the y-coordinates.

So, in your problem (-3 + 12)/2 = 9/2   and  (-5 + 12)/2 = 7/2

The midpoint is (9/2, 7/2)

Answer:

If the game will start at 11:00 A.M., but the players must arrive at the field three-quarters of an hour early to warm up, it refers to 8:45 a.m. Why? If we start to count in 11 backward and start to trace the three-quarters, it shows that 10:45, 9:45, and 8:45 are the three-quarters. So Hamid statement that he has to be at the field at 9:45 A.M is not correct.

Answer:

-8.4 + 6 hope this helped!

Step-by-step explanation:

Answer:

-38

Step-by-step explanation:

-8.x – 3y

x = 4

y = -2

Since we have the value for x and y we can use that and substitute it into the expression

-8(4) - 3 (-2)

-32 - 6

When you add 2 negative numbers (or subtract them) they will give you a bigger number so think of it as adding 2 positive numeber, but then putting a negative sign in the beginning of it.

-32 - 6

-38

Answer:

0.46875 ; 1.133 ; $17 ;19.27

Step-by-step explanation:

Number of slots = 32

0, 00, {1,.. 30}

Odd outcomes = {1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29}

1.) probability of winning :

P(winning) = number of odd outcomes / tot possible outcomes

P(winning) = 15 / 32 = 0.46875

2.)

Odds against winning :

Number of losing outcomes / number of winning outcomes

Not odd numbers / odd numbers = 17 /15 = 1.133

C.)

Payoff odd = 1:1

If bet value = $17 ;

Profit made on winning = $17 * 1 = $17

d.)

If Payoff odd = odd against winning = 17 / 15

Profit on $17

17/ 15 * 17

(1.1333333) * 17

= 19.27

Answer + Explanation:

First, find what the sum of the interior angles must be. You can use the formula 180(n - 2) where n is the number of sides to find this.

n = 5, so 180( 5 - 2) = 180 * 3 = 540 degrees.

Then, you can add up all the interior angles of the pentagon and it will add to 540. This means that:

2x + x + 2x + 90 + 90 = 540

5x + 180 = 540

5x = 360

x = 72

Then you can go through and find the measure of each angle:

S = 90 degrees (given)

T = 2x = 2 * 72 = 144 degrees

U = x = 72 degrees

V = 2x = 72 * 2 = 144 degrees

W = 90 degrees (given)

Answer:

1) x=3/2y+1/2

2)x=-1/3y+-5/3

Step-by-step explanation:

1)

Let's solve for x.

2x−3y=1

Step 1: Add 3y to both sides.

102x−3y+3y=1+3y

2x=3y+1

Step 2: Divide both sides by 2.

2x/2

=

3y+1/2

x=3/2y+1/2

Answer:

t^2+4

Step-by-step explanation:

The perimeter of the table can be given by the equation 2l+2w, and we know the length is 2t-3, meaning 2(2t-3)+2w=2t^2+4t+2, as we know 2t^2+4t+2 is the perimeter. Simplifying we get:

4t-6+2w=2t^2+4t+2

4t+2w=2t^2+4t+8

2w=2t^2+8

w=t^2+4

This means that the table's width is t^2+4

Answer:

Step-by-step explanation:

h(x) = 7 - x - 2x^5

h(-1) = 7 + 1 - 2(-1)^5

h(-1) = 7 + 1 + 2

h(-1) = 10

Now differentiate h(x)

h'(x) = -1 - 2*5*x^4

h'(x) = -1 - 10x^4

h'(x) = -1 - 10(x)^4

h'(x) = -1 - 10 (x)^4

h'(-1) = -1 - 10(10000)

h'(-1) = -1 - 100000

h'(-1) = - 99999

Answer:

609 males

Step-by-step explanation:

A city council organized a marathon race to promote good health.

Let the number of

Females = x

Males = y

There were 3 times as many female participants as male participants in the marathon.

3x = y

If the total number of participants was 812,

x + y = 812..... Equation 1

We substitute 3x for y in Equation 1

x + 3x = 812

4x = 812

x= 812/4

x = 203 females

3x = y

Solving for y

3(203) = 609 males

The number of males participants = 609

The number of high outliers in the data set will be 1.

The interquartile range is a measurement of a data set's "middle fifty." A range is a measurement of where a set's beginning and end are located.

To get the interquartile range, we must know the first and third quartiles. To find those, we need to know the median of the data.

The following histogram summarizes the ages of the 25 employees who work for Elon's company. According to the 1.5 IQR wall for outliers. The number of the high outliers will be 1.

Therefore, the number of high outliers in the data set will be 1.
