Mary had to guess at a chosen number between 1 and 10, to get to be the first in line. What’s the probability that she’ll choose the correct number?
Answer:
1 in 10, or 10% because there is a 90% chance she will choose the wrong number.
Answer:
[tex]\frac{1}{10}[/tex]
Step-by-step explanation:
1-10 is 10 numbers, only one of which is the correct one.
The resulting proportion is:
[tex]\frac{1}{10}[/tex]
A) sumar: m; n; e3; -2n; 10m b) sumar: x; 2y; -4y; 6x; 2x; c) sumar: a; b; c; 2a; 3c; -2a; 3b; 4c d) sumar: 2a; -b; 3c; -2a; 3b; 2c
Answer:
a) m + n + e3 + ( -2n) + 10m = 11m - n + e3
b) x + 2y -4y + 6x + 2x = 9x -2y
c) a + b + c + 2a + 3c -2a + 3b + 4c = a + 4b + 8c
d) 2a -b + 3c -2a + 3b + 2c = 2b + 5c
Step-by-step explanation:
En cada uno de los casos:
1) Reorganizas los términos
2) sumas los coeficientes de los términos semejantes
a) m + n + e3 + ( -2n) + 10m
1) Reorganizando los términos
m + 10m + n + ( -2n) + e3
2) Sumando los coeficientes de los términos semejantes
(1 + 10) m + (1 - 2) n + e3
(11)m + (-1)n + e3
11m - n + e3

b) x + 2y - 4y + 6x + 2x
1) Reorganizando los términos
x + 6x +2x + 2y - 4y
2) Sumando los coeficientes de los términos semejantes
(1 +6 +2) x + (2- 4) y
(9) x + (-2)y
9x -2y

c) a + b + c + 2a + 3c -2a + 3b + 4c
1) Reorganizando los términos
a + 2a - 2a + b + 3b + c + 3c + 4c
2) Sumando los coeficientes de los términos semejantes
(1 + 2 - 2 ) a + (1 +3) b + ( 1 + 3 +4) c
(1) a + (4)b + (8)c
a +4b + 8c
__________________
d) 2a -b + 3c -2a + 3b + 2c
1) Reorganizando los términos
2a - 2a - b + 3b + 3c +2c
2) Sumando los coeficientes de los términos semejantes
(2 - 2) a + (-1 +3) b + (3 +2)c
(0) a + (2) b + (5) c

Grace and her brother need $400 to go to band camp. Their parents have agreed to help them earn money by paying them $25 each time they mow the lawn and $10 for each hour they babysit their younger brother. They will have to do a combination of both chores to earn the money.
Select the equation that represents the number of lawns they can mow, m, and hours they can babysit, b, to earn $400.
M. 10m+ 25b= 400
P. 10m− 25b= 400
R. 25m+ 10b= 400
S. 25m− 10b= 400
Answer:
25m + 10b = 400
Step-by-step explanation:
Total amount that can be earned = $ 400
Amount earned on mowing a lawn = $ 25
Amount earned per hour on babysitting = $10
Amount earned for mowing one lawn is $ 25, so amount earned for mowing m lawns will be $ 25m
Amount earned for one hour of babysitting is $ 10, so amount earned for babysitting for b hours will be $ 10b
Total amount earned = Amount earned from mowing m lawns + Amount earned from babysitting for b hours
Using the values from above, we can set up the equation as:
400 = 25m + 10b

Mathhhhhhhhhhh which one is correct
Answer:
slope = 4
y intercept = -3
Step-by-step explanation:
The equation is put in slope intercept form
Slope intercept form: y = mx + b
where m = slope and b = y intercept
looking at slope intercept form
4 is located where m should be , meaning that the slope is equal to 4 and
-3 is located where b should be , meaning that the y intercept is -3
Therefore the answers are the first and last option choices.

Write your answer as a fraction in simplest form.
please help :(
Answer: The probability of picking a pen from the first box and a crayon from the second box is 5/8 x 1/4 = 5/32.
Step-by-step explanation:
What is the probability of choosing a pen from the first box? It is 5/8.
What is the probability of selecting a crayon from the second box? It is 3/12 = 1/4.
The probability of picking a pen from the first box and a crayon from the second box is 5/8 x 1/4 = 5/32.

Answer:
It is D
Step-by-step explanation:
Within each coordinate it represents (x,y)
The x moves along the horizontal line and the Y moves along the vertical line.
For example: For (-5,5) move to the left 5 times, then move up 5 times.
A negative X goes to the left and a negative Y goes down.
A positive X moves to the right and a positive Y moves up.
an article bought a television for 2500 dollars and sold for 2325dollars find a.loss b.loss%
Answer:
Loss= $175
Loss %= 7%
Step-by-step explanation:
First of all, you find the difference between 2500 and 2325 which is 175, as his has decreased, it is a loss of $175
To find the percentage you do the difference over the original amount
So 175/2500 which will give you 0.07
0.07 x 100 will give you 7%
Gale owns a car that is worth $9,500 but she still owes $7,400 on the car loan. She has a student loan in the amount of $6,000 and she has a savings account with a balance of $1500. The balance on her credit card is $3200. What is her net worth?
Answer:
$8000
Step-by-step explanation:
Given: Car worth = $9,500, car loan = $7,400. Student loan = $6,000, savings account = $1500. The balance on her credit card is $3200.
Formula: Total Assets - Total Liabilities - Intangible Assets = Tangible Net Worth.
To find: Gale's net worth
Solution: You can calculate your net worth by subtracting your liabilities (debts) from your assets.
Firstly, calculate the total amount of assets by adding them together;
Total assets = Car worth + car loan + Student loan + savings account + balance on her credit card =
$9,500 + $7,400 + $6,000 + $3200 =$26,100
Secondly, calculate the Liabilities by adding them together;
Car loan + Student loan =
$7,400 + $6,000 = $13,400
Then, calculate the Intangible Assets by adding them together;
Savings account + The balance on her credit card =
$1500 + $3200 = $4700
Finally, subtract the total amounts;
$26,100 - $13,400 - $4700 = $8000
(Note:- If your assets exceed your liabilities, you will have a positive net worth. Conversely, if your liabilities are greater than your assets, you will have a negative net worth.)

Riley owns an orchard that has a rectangular fence. The orchard is 36 yards long and 18
yards wide. If she walks across the diagonal length of the orchard, how much distance
would she cover?
Answer:
40.25 yds to the the nearest 100th
Step-by-step explanation:
The diagonal forms a right triangle with the length and width.
The diagonal is the hypotenuse
So, let d = the diagonal distance
[tex]d^{2}[/tex] = [tex]18^{2} + 36^{2}[/tex]
= 324 + 1296
= 1620
d = [tex]\sqrt{1620}[/tex] = 40.25 yds to the the nearest 100th

What is the slope of the line shown below?
Answer:
2
Step-by-step explanation:
ΔX = -1 – 2 = -3
ΔY = -4 – 2 = -6
-6 divided by -3=2
Hope it helps ;)
Step-by-step explanation:
[tex]slope = \frac{y2 -y1 }{x2 - x1} \\ = \frac{ - 4 - 2}{ - 1 - 2} \\ = \frac{ - 6}{ - 3} \\ = 2[/tex]
even if x₁ = -1, y₁ = -4 and x₂ = 2, y₂= 2 the result remains the same.
