|-80|=80
|x| -≥ this symbol is named as mod
we use this to find the absolute value...
it can be explained easily as meaning like rounding off
I'm that even the number given inside in negative we should write the answer only in positive
negative number can never be the answer of absolute value

A city council organized a marathon race to promote good health. There were 3 times as many female participants as male participants in the marathon. If the total number of participants was 812, how many participants were male
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

what is 1/5 + 1/6=
Pls I need help
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

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 how many high outliers are there in the data set
Answer:
Step-by-step explanation:
1
The number of high outliers in the data set will be 1.
What is the interquartile range?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.

find the value of each angle.
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:
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:
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.

-8.x – 3y if x = 4 and y = -2
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:
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

A modified roulette wheel has 32 slots. one slot is 0, another is 00, and the others are numbered 1 through 30, respectively. You are placing a bet that the outcome is an odd number. (In roulette, 0 and 00 are neither odd nor even.)<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
a. What is your probability of winning ?
The probability of winnign is ?
( type an integer or a simplified fraction)
b. What are the actual odds against winning are ?
c. When you bet that the outcome is an odd number, the payoff odds are 1:1. How much profit do you make if you bet $17 and win ?
If you win, the pay off is ?
d. How much profit should you make on the $17 bet if you could somehow convice the casino to change its payoff odds so that they are the same as the actual odds against winning ?
(rounds to the nearest cent as needed.)Type your question here
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

[tex]m = \frac{dy}{dx} = \frac{y_2-y_1}{x_2-x_1}[/tex]
Substitute these coordinate values in.

Hence, the slope is -3.
Find the y-intercept.From the graph, the line passes through the origin point. Therefore, the y-intercept is (0,0).

The perimeter of a rectangular coffee table is given by the trinomial 2t2+4t+2. The table's length is 2t-3. What is the table's width?
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
