a bag contains 5 red balls and 6 green balls. if two balls are taken out successively, without replacement, what is the probability that green is picked on the first pick given that at least one red is chosen? g
The probability of picking a green ball on the first pick, given that at least one red is chosen, is 11/19.
The probability of picking a green ball on the first pick, given that at least one red is chosen, can be calculated by finding the total number of possible outcomes and then dividing by the number of outcomes that include at least one red ball. In this bag, there are 11 green balls and 5 red balls, for a total of 16 balls. Since two balls are taken out successively without replacement, the total number of outcomes is 16 choose 2, or 120. Of those, there are 10 outcomes that include at least one red ball, so the probability of picking a green ball on the first pick, given that at least one red is chosen, is 11/19. This can be calculated by dividing the number of outcomes that include at least one red ball (10) by the total number of outcomes (120).

4. Find the lateral surface area of the cylinder.
Round to nearest hundredth.
22 ft.
6 ft.
Answer: The lateral surface area of the cylinder can be found using the formula: πr h, where r is the radius and h is the height of the cylinder.
Given that the height of the cylinder is 22 ft, and the diameter is 6 ft, the radius can be found by dividing the diameter by 2: r = 6 / 2 = 3 ft.
So the lateral surface area of the cylinder is: πr h = π * 3 * 22 = 66 * π ≈ 208.36 sq ft.
Rounding to the nearest hundredth, the lateral surface area of the cylinder is 208.36 sq ft.

The missing angles in the figure are:
∠XVR = 125°
∠RVS = 55°
∠WVS = 125°
∠RST = 110°
∠RSV = 70°
∠VSU = 110°
∠UST = 70°
∠TUS = 39°
How to find the missing angles?
Angle geometry is a branch of mathematics that deals with the study of angles and their properties in two-dimensional figures such as circles, triangles, and polygons.
∠XVW + ∠XVR = 180° (sum of angles on a straight line is 180° )
Thus, ∠XVR = 180 - 55 = 125°
∠RVS = 55° (vertically opposite angles are equal)
∠WVS = 125° (vertically opposite angles are equal)
∠RST = 55 + 55 = 110° (exterior angle of a triangle)
∠RSV = 180-55-55 = 70° (sum of angles in a triangle is 180°)
∠VSU = 110° (vertically opposite angles are equal)
∠UST = 70° (vertically opposite angles are equal)
∠TUS = 180 - 70 -71 = 39° (sum of angles in a triangle is 180°)

Parallel to the line through (1,-2) (-6,3)
Step-by-step explanation:
A line that is parallel to another line has the same slope but a different y-intercept. The slope of the line through the points (1,-2) and (-6,3) can be found using the slope-point formula:
slope = (y2 - y1) / (x2 - x1) = (3 - (-2)) / (-6 - 1) = 5/7
So, a line that is parallel to this line would have the same slope of 5/7. To find an equation for a line with this slope that passes through a different point, we can use the point-slope formula:
y - y1 = m * (x - x1)
Where m is the slope and (x1, y1) is a point on the line. We can choose any point to use in this formula, but a common choice is the origin (0,0). So, plugging in the values we have:
y - 0 = 5/7 * (x - 0)
y = 5/7 * x
This is the equation for a line that is parallel to the line through the points (1,-2) and (-6,3) and passes through the origin.

If this pattern continues, what is the total amount of money he will raise if his race is
26 miles total?
The pattern tells that the amount raised by Robert in 26th mile is $90.
What is a pattern?
A recurring arrangement of numbers, forms, colours, and other elements constitutes a pattern in mathematics. The Pattern can be connected to any kind of occasion or thing. When a group of numbers are arranged in a particular way, the arrangement is referred to as a pattern.
The amount of money raised by Robert for first mile = $5
The amount of money raised by Robert for second mile = $6
The amount of money raised by Robert for third mile = $7.2
The difference between amount raised in first and second mile = $1
The difference between amount raised in second and third mile = $1.2
Similarly, the difference between amount raised in third and fourth mile will be = $1.4
Similarly, the difference between amount raised in fourth and fifth mile will be = $1.8
Following this pattern the difference between 25th and 26th mile will be = (26 × 0.2) + 0.4 = $5.8
Now, the amount raised in 26th mile = 84.2 + 5.8 = 90

here are two graphs of clem's waist height vs. time. how are these graphs similar? how are they different?
Both graphs show the same relationship between Clem's waist height and time, but the exponential graph shows a more rapid increase in Clem's waist height over time.
Both graphs depict the relationship between Clem's waist height and time. The first graph is linear and is represented by the equation y = 2x + 3, where y is Clem's waist height and x is the amount of time that has passed. The second graph is exponential and is represented by the equation y = 2^x + 3. Both graphs show that Clem's waist height increases with time – the difference is that the linear graph shows a steady, linear increase, while the exponential graph shows an exponential increase. For example, if Clem's waist height was 3 inches at the start, then after 1 hour it would be 5 inches on the linear graph, but 8 inches on the exponential graph. This difference can be seen in the calculations: 1 hour on the linear graph would be 3 + (2 x 1) = 5 inches, while 1 hour on the exponential graph would be 3 + (2^1) = 8 inches.
In summary, both graphs show the same relationship between Clem's waist height and time, but the both graphs show the same relationship between Clem's waist height and time, but the exponential graph shows a more rapid increase in Clem's waist height over time.

.A circle is inscribed in quadrilateral ABCD. If AB = 4, BC = 5, and CD = 8,
what is DA?
Step-by-step explanation:
I just answered this. how often was that posted ?
the distance of a vertex to its 2 neighboring circle touching points is the same, because tangents emanating from the same point to the same circle must have the same distance to the touching points.
so, AB splits into a (from A to the circle touching point on AB) and b (from the circle touching point on AB to B).
b = AB - a
BC splits into b (from B to the circle touching point on BC) = AB - a, and c (from the circle touching point on BC to C).
c = BC - (AB - a) = BC - AB + a
CD splits into c (from C to the circle touching point on CD) = BC - AB + a, and d (from the circle touching point on CD to D).
d = CD - (BC - AB + a) = CD - BC + AB - a
DA now splits into d (from D to the circle touching point on DA) and ... a (from the circle touching point on DA to A).
a = DA - (CD - BC + AB - a) = DA - CD + BC - AB + a
0 = DA - CD + BC - AB
DA = CD - BC + AB = 8 - 5 + 4 = 7
Answer:
DA = 7
Step-by-step explanation:
You have quadrilateral ABCD with an inscribed circle and side lengths AB=4, BC=6, CD=8, and you want to know the length of DA.
Inscribed circleThe tangents from each vertex of the quadrilateral to the inscribed circle are the same length, so we can work our way around the quadrilateral to find the missing length. The attached figure shows the tangent lengths working counterclockwise from vertex A.
The sum of the tangents from A and D is ...
x + (7 -x) = 7
The length of DA is 7 units.

Additional comment
The sum of the lengths of opposite sides is the same in any quadrilateral with an inscribed circle. Here, that sum is 4+8 = 12, so the unknown side is 12-5 = 7.

Thus, the population of such a type of organism satisfies a differential equation of the form dP/dt = aP^2 - bP with a, b > 0. This problem investigates the solutions to such an equation. Sketch a graph of dP/dt against P. Note when dP/dt is positive and negative. dP/dt < 0 when P is in dP/dt > 0 when P is in
As a result, on a graph of dP/dt vs P, the curve would be concave down for P b/a and concave up for P > b/a. The curve would reach its maximum when P = b/a, with dP/dt equal to zero.
What is equation?In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign.
Here,
The equation dP/dt = aP² - bP represents the rate of change of the population P over time t.
When dP/dt is positive, the population is increasing. When dP/dt is negative, the population is decreasing.
To find when dP/dt is positive and negative, we need to find the critical points where dP/dt = 0.
Solving the equation dP/dt = aP² - bP = 0, we get:
aP² - bP = 0
aP(P - b/a) = 0
This equation has two solutions: P = 0 and P = b/a.
For P < b/a, dP/dt is negative (the population is decreasing). For P > b/a, dP/dt is positive (the population is increasing).
So, on a graph of dP/dt against P, the curve would be concave down for P < b/a and concave up for P > b/a. At P = b/a, the curve would have a maximum and dP/dt = 0.

tammy, felipe, and david sent a total of text messages over their cell phones during the weekend. david sent times as many messages as felipe. felipe sent fewer messages than tammy. how many messages did they each send?
The total Messages that Tammy, Felipe, and David sent are 30, 50, and 45 messages respectively.
Let's denote the number of text messages sent by Tammy as x, Felipe as y, and David as z. Based on the information given, we have:
y < x and z = 3y.
The total number of messages they sent is x + y + z = x + y + 3y = 4y + x.
Since the total number of messages sent is not specified, we can choose an arbitrary value for the total number of messages. Let's choose 90 messages. Then, we have:
4y + x = 90
x = 90 - 4y.
Substituting z = 3y into x = 90 - 4y, we get:
3y = 90 - 4y
7y = 90
y = 90/7 = 15.
Plugging y = 15 into x = 90 - 4y, we get:
x = 90 - 4 * 15 = 30.
Therefore, Tammy sent 30 messages, Felipe sent 15 messages, and David sent 45 messages.
