A bag contains equal-sized disks that are either red, green, yellow, or blue. There are 6 red disks, 3 green disks, 6 yellow disks, and 5 blue disks. If a disk is selected at random from the bag, what is the probability that the disk will be either red or yellow?
Answer:
3/5
Step-by-step explanation:
There are 20 discs in total. We need to find the probability of picking out either a red or yellow disc. There are 6 red discs and 6 yellow discs, a total of 12. This means that our chances of picking out a red or yellow disc from the bag is 12/20, which can be simplified to 3/5.
Answer:
3/5 or 60%
Step-by-step explanation:
Total disks: 6+3+6+5= 20
red+yellow disks: 6+6=12
red+yellow/total disks=12/20
FRACTION:
simplify: 12/20=6/10=3/5

Let’s say you separated your candy into two bags. One bag for chocolate bars and one bag for everything else. In the chocolate bar bag there were the following; 10 dark chocolate, 23 milk chocolate, 14 chocolate with nuts and 3 white chocolate bars. If you reached into the bag without looking, what is the probability of getting a dark chocolate bar?
Answer:
10/50 or 1/5 or 20 % chance
Step-by-step explanation:
well to find this out we have to add all of the chocolates together
10+23+14+3
33+17
50
And then we divide the amount of dark chocolate by 50
And it will be 10/50 or 1/5
Item 8 Question 1 The expression 10a+6c gives the cost (in dollars) for a adults and c children to eat at a buffet restaurant. a. The cost for 1 adult is $ . The cost for 1 child is $ . b. The total cost for 1 adult and 3 children is $ . Question 2 c. Is $30 enough for a family of 2 adults and 2 children to eat at the buffet?
Given:
The expression for total cost (in dollars) is
\(10a+6c\)
where, a adults and c children to eat at a buffet restaurant.
To find:
(a) The cost for 1 adult. The cost for 1 child .
(b) The total cost for 1 adult and 3 children is $ .
(c) Is $30 enough for a family of 2 adults and 2 children to eat at the buffet?
Solution:
(a) The expression for total cost (in dollars) is
\(10a+6c\)
Coefficient of a and c represents the cost for each adult and child respectively.
Therefore, the cost for 1 adult is $10. The cost for 1 child $6 .
(b) Substitute a=1 and c=3 in the given expression, to find the total cost for 1 adult and 3 children.
\(10(1)+6(3)=10+18\)
\(10(1)+6(3)=28\)
The total cost for 1 adult and 3 children is $28.
(c)
Substitute a=2 and c=2 in the given expression, to find the total cost for 2 adult and 2 children.
\(10(2)+6(2)=20+12\)
\(10(2)+6(2)=32\)
Since, 32>30, therefore, $30 is not enough for a family of 2 adults and 2 children to eat at the buffet.
Hey i need help finding the orthocenter for the following points, please show the steps you used. thanks
(-3, 0.5)
(3,3)
(2,-1)
9514 1404 393
Answer:
(81/43, -31/43) ≈ (1.884, -0.7209)
Step-by-step explanation:
The orthocenter is the intersection point of the altitudes of the triangle. Since this is not a right triangle, you need to find the equations of the altitude lines, then find where those intersect.
If we call the points A, B, C in the order given, the attached figure shows the altitude lines from B perpendicular to AC, and from C perpendicular to AB.
We can find the equation of the perpendicular line using the form ...
∆x·x +∆y·y = c
where ∆x and ∆y are the differences in coordinates between the points on the "side" and the value of constant 'c' is determined by evaluating the expression using x and y as the coordinates of the opposite vertex.
__
For line AC, we have ...
(∆x, ∆y) = C - A = (2, -1) -(-3, 0.5) = (2+3, -1-0.5) = (5, -1.5)
Then the equation of the first altitude line is ...
5x -1.5y = 6(3) -1.5(3) = 10.5
Multiplying by 2 puts this in standard form:
10x -3y = 21
__
For line AB, we have ...
(∆x, ∆y) = B - A = (3, 3) -(-3, 0.5) = (3+3, 3-0.5) = (6, 2.5)
Then the equation of the second altitude line is ...
6x +2.5y = 6(2) +2.5(-1) = 9.5
Multiplying by 2 puts this in standard form:
12x +5y = 19
__
Then the orthocenter is the solution to the system of equations ...
10x -3y -21 = 0
12x +5y -19 = 0
This set of equations can be solved a number of ways. One is the "cross-multiplication" method.
1/(10·5 -12·(-3)) = x/(-3·(-19) -5·(-21)) = y/(-21(12) -(-19)(10))
x = 162/86 = 81/43
y = -62/86 = -31/43
The orthocenter is (81/43, -31/43) ≈ (1.884, -0.7209).
_____
Additional comment
The "cross multiply method" is based on cross products when the equations are written in standard form:
ax +by +c = 0
dx +ey +g = 0
Usually, the coefficients are written in two rows of four, with the first column repeated at the end:
a b c a
d e g d
Then cross products are formed, where diagonal down is positive and diagonal up is subtracted from that:
p1 = (ae -db), p2 = (bg -ec), p3 = (cd -ga)
These give the solution to the equations when put in the form ...
1/p1 = x/p2 = y/p3 ⇒ x = p2/p1 and y = p3/p1
If you look at videos of this "cross multiply method," they will put the 1/p1 at the end of the string of equalities, and they will use the coefficients in the order starting with b instead of a. I find the arrangement here easier to remember, so less likely to get confused.
Further comment
You can, of course, find the slopes of the lines, and their opposite reciprocals, then use a point-slope form or some other method for writing the equations of the altitude lines. The solution to the equations can proceed by substitution or elimination. No doubt these methods are somewhat familiar. The method used here tries to get to the answer much more quickly with a lot less writing. (Unfortunately, it takes a bit of writing to explain it all.)

Which equation does the graph below represent? (1 point)
A coordinate grid is shown. The x-axis values are from negative 5 to positive 5 in increments of 1 for each grid line, and the y-axis values are from negative 15 to positive 15 in increments of 3 for each grid line. A line is shown passing through the ordered pairs negative 4, 12 and 0, 0 and 4, negative 12.

1)
y = fraction negative 1 over 3x
2)
y = −3x
3)
y = 3x
4)
y = fraction 1 over 3x
Answer:
3) y = 3x
Step-by-step explanation:
a line equation is typically written as
y = ax + b
a is the slope, the inclination of the line. it is defined as ratio of "y coordinate change / x coordinate change" when going from one point to another on the line.
so, e.g. going from (0,0) to (4,12) means
x changes by +4 (from 0 to 4)
y changes by +12 (from 0 to 12)
so, the slope is +12/+4 = 3
and the line equation starts like this
y = 3x + b
now, b is the y-intercept : the y value, where the line intercepts (crosses) the y-axis. in other words, the y value where x = 0.
and we have that right away, as the line goes through (0,0). that IS the y-intercept point. the y value there is 0.
therefore, b=0.
and so the full line equation is
y = 3x

Two functions are represented below what is the difference in rate of change between functional a function A and function B. Be sure to include the rate of change of each function in your question answer(8.F.2)
The difference in the rate of change between Function A and function B is -2.
The difference in the rate of change between function A and function B, we first need to identify the rate of change for each function. The rate of change, also known as the slope, represents how much the dependent variable (y) changes for every unit increase in the independent variable (x).
Let's assume function A is represented by the equation y = 2x + 3, and function B is represented by the equation y = 4x - 1.
For function A: y = 2x + 3, the coefficient of x is 2, indicating that for every unit increase in x, y increases by 2. Therefore, the rate of change for function A is 2.
For function B: y = 4x - 1, the coefficient of x is 4, indicating that for every unit increase in x, y increases by 4. Therefore, the rate of change for function B is 4.
Now, to find the difference in the rate of change between function A and function B, we subtract the rate of change of function B from the rate of change of function A:
Difference in rate of change = Rate of change of function A - Rate of change of function B
= 2 - 4
= -2
The difference in the rate of change between function A and function B is -2. This means that for every unit increase in x, function B increases at a rate that is 2 units greater than function A. It indicates that function B has a steeper slope and a faster rate of change compared to function A.
In summary, the difference in the rate of change between function A and function B is -2.

5. Diego says that d = 3t represents his walk, where d is the distance walked in miles and t is
the time in hours.
Explain why d = 3t relates the distance Diego walked to the time it took.
a.
b.
Write two equations that relate distance and time: one for Elena and one for Andre.
The equation d = 3t relates the distance Diego walked to the time it took because it means that Diego walks at a constant speed of 3 miles per hour. So, for every hour he walks, he covers a distance of 3 miles. Therefore, the distance he walks (d) is directly proportional to the time it takes him to walk (t).
a. An equation that relates distance and time for Elena could be d = 2t, where d is the distance she travels in miles and t is the time it takes her in hours. This equation means that Elena walks at a constant speed of 2 miles per hour, so for every hour she walks, she covers a distance of 2 miles.
b. An equation that relates distance and time for Andre could be d = 5t, where d is the distance he travels in miles and t is the time it takes him in hours. This equation means that Andre walks at a constant speed of 5 miles per hour, so for every hour he walks, he covers a distance of 5 miles.

The x-intercept is 5 and the y-intercept is 2.
The standard form of the line is 2x + 5y = 10.
How to find the x-intercept, y-intercept and equation in standard form?The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis. In other words, the x -intercept is the value of x when y = 0 and the y-intercept is the value of y when x = 0.
Hence, the x-intercept is 5 and the y-intercept is 2.
Let's find the equation in standard form.
Ax + By = C
where
A, B and C are constantUsing slope intercept form,
y = mx + b
where
m = slopeb = y-interceptHence, using (5, 0) and (0, 2)
m = 2 - 0 / 0 - 5
m = - 2 / 5
