Answer:
0.0083 = 0.83% probability that the boys will stand in alphabetical order from left to right in the picture
Step-by-step explanation:
Probability:
A probability is given by the number of desired outcomes divided by the number of total outcomes.
Arrangments of x elements:
The total number of arrangments of x elements is given by:
[tex]A_{x} = x![/tex]
Desired outcomes:
Standing in alphabetical order, so only 1 possible outcome, which means that [tex]D = 1[/tex]
Total outcomes:
Arrangments of 5 people, so
[tex]T = A_{5} = 5! = 120[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{1}{120} = 0.0083[/tex]
0.0083 = 0.83% probability that the boys will stand in alphabetical order from left to right in the picture

At a local fitness center, gym members pay $3 per workout with an annual membership fee of $140. Non-members pay $10 per workout. If you plan on working out an average of twice a month for the next year, is a membership worth the investment? Show your thinking
PLEASE HELP
Answer:
Yes the membership is worth it. If you have a membership you will pay $140 for the whole year. Then, it is $3 everytime you workout and if you plan on working out 2 times a month the total will be $72 dollars. So $72 + $140 is $212 yearly. If you don't get the membership you pay $20 a month because you will workout twice a month. So, 20 times 12 is $240. It may seem like it's not worth it but it actually comes out cheaper. So, yes I do think the membership is worth it.
Step-by-step explanation:

Answer:
7/3
1
1/2
undefined
Step-by-step explanation:
1/1 ÷ 3/7 = 7/3 because you multiply the 1st fraction by the reciprocal of the 2nd
1/1 = 1
1/2 = 1/2
1/0 = undefined; anything divided by zero is considered to be undefined
Dunya randomly chooses a number from 1 to 10. What is the probability she
chooses a number less than 6?
Answer: 1/2
Step-by-step explanation:
The numbers that are less than 6 are 1, 2, 3, 4, and 5. Thus simply means that there are 5 numbers that are less than 6.
The probability that she chooses a number less than 6 will then be:
= 5/10
= 1/2

an electronic motor that's rated 5 horsepower can produce blank in equivalent A) 0.007 watts B) 5 watts a C) 17.05 watts D) 3730 watts
Answer: D) 3730 watts
Step-by-step explanation:
We know the relation:
1 horsepower = 745.7 watts
Then a rated 5 horsepower is 5 times 745.7 watts, this is equal to:
5*745.7 watts = 3728.5 watts
We can round it up to 3730 watts (the nearest tens) so it matches with one of the options.
From this, we can conclude that the correct option is option D; 3730 watts

13. Let f(x) = 5x + 10 and g(x) = 2*
a) Find f(2)
b) Find g(2)
c) Find f(2) + g(2)
Answer:
A) f(2) = 20
B) g(2) = 2
C) f(2) + g(2) = 22
Step-by-step explanation:
For part A, you change the x to become 2, to have the equation of 5(2)+10. You then solve in order to get 20.
For part B, I'm not exactly sure what the equation is, but you do the same thing for part A. Since there is no x variable then just keep the answer you have. Meaning it is 2
Finally, part C is adding your answers from part A and part B to get the final answer of 22.
How should I start to complete the equation????
Answer:
Find the slope and the y-intercept
Step-by-step explanation:
To find slope, use the equation [tex]\frac{y-y}{x-x}[/tex]. First, find two points on the line that are near each other and are whole numbers. Then you substitute the points into the equation. So for example, if I had the points (0,0) and (1,2), the substitution would be:
[tex]\frac{2-0}{1-0}[/tex]
To find the y-intercept, find where the line crosses over the y-axis. Then put in the y value.
If you do not know where to put slope and y-intercept:
y=mx+b
m=slope
b=y-intercept
slope= output/input
Answer:
the answer may vary, seeing as you could use any of the coordinates, but in my case i got : y = -1/2 + 4
Step-by-step explanation:
formula : y = mx + b
to find your ' b ' you had to determine where the y intersects. in this case, it intersected on positive four.
to determine your m, you have to subtract two of the plotted coordinates from each other, in my case it was (-2,5) and (4,2)
y2 - y1
-----------
x2 - x1
2 - 5
--------
4 - ( -2 )
-3
-----
6
WHICH MEANS
m = -1/2

Silas had 3 times as much money as Raja. Silas spent $84 of his money to buy a birthday gift for his grandma while Raja was awarded $42 for winning a competition. In the end, they had the same amount of money. How much did they have altogether at first?
Answer:
Total money they had at first $252.
Step-by-step explanation:
Let,
x be the amount Silas had originally
y be the amount Raja had originally
According to given statement;
x = 3y Eqn 1
x - 84 = y + 42 Eqn 2
Putting x=3y in Eqn 2
3y - 84 = y + 42
3y - y = 42 + 84
2y = 126
Dividing both sides by 2
[tex]\frac{2y}{2}=\frac{126}{2}\\y=63[/tex]
Putting y = 63 in Eqn 1
x = 3(63)
x = 189
Total money they originally had = 189 + 63 = $252
Hence,
Total money they had at first $252.

the dimensions of a triangular prism are shown below what is the volume of the prism in cubic feet
Answer:
B. 192.5 ft³
Step-by-step explanation:
To find the volume of a triangle prism, multiply the base, height, and length together, and then divide it by 2 (or multiply that by 0.5).
(5 * 7 * 11)/2
Multiply 5 by 7 to get 35.
(35 * 11)/2
Multiply 35 by 11 to get 385.
385/2
192.5 ft³ is the volume of this triangluar prism.

Can someone answer number 3 and 4 for me please? :))
Answer:
3. Yes, because 160 / 4 = 40 and 120 / 3 = 40.
4. 10, because 24 / 12 = 2 and 20 / 2 = 10
Answer:
3. David and Aryana use their phones at the same rate.
4.10 parts of water to 20 parts of cornstarch.
Step-by-step explanation:
3. First, you have Aryana who uses 160 mins in 4 days. Then there is David who has 120 minutes in 3 days. You want to divide the minutes by days to see how many minutes per day they use their phone. 160/4=40 120/3=40. David and Aryana use their phones at the same rate.
4. First, you have 24c to 12w (c is cornstarch and w is water). If you want to find 20c and what w is, you need to make c into a smaller number. What I mean is that you need to divide the equation as low as it can go, this one happening to be 12. So you do 24 to 12/12 = 2c to 1w. You then multiply the number back up to twenty. so 2*10 = 20 1*10=10. Your final answer is 10 parts of water to 20 parts of cornstarch.

A number, y, is five times another number, x. The sum of the two numbers is 42. Write the system of equations.
Answer:
5x+x=42
6x=42
x=7
Step-by-step explanation:
Answer:
y = 5x
x + y = 42
Step-by-step explanation:
If y is 5 times greater than x, this can be represented by y = 5x
The sum of x and y is 42, so this can be represented by x + y = 42
So, the system of equations will be:
y = 5x
x + y = 42
Graph the line with the equation y
