The probability of picking a factor of 10 is 1/4 or 0.25 as a decimal.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
To calculate the probability of picking a factor of 10, we need to count the number of cards that are factors of 10 and divide that by the total number of cards.
The factors of 10 are 1, 2, 5, and 10. Out of the given cards, only 2 is a factor of 10.
Therefore, the probability of picking a factor of 10 is 1/4 or 0.25 as a decimal.

Answer:
133
Step-by-step explanation:
All 3 angles of a triangle must equal 180, so let's make these equal to that
[tex](x + 13) + (10x + 13) + (2x - 2) = 180[/tex]
Now let's combine the X's and the regular numbers together.
[tex]13x + 24 = 180[/tex]
Next, subtract 24 to get all the numbers on the right side.
[tex]13x = 156[/tex]
And lastly, we divide by 13 to get X alone
[tex]x = 12[/tex]
Since Q is (10x + 13), we plug that 12 in
[tex]10(12) + 13 = 133[/tex]

5 0, 6
6 7
Key: 3|1 means 3.1
What is the mean, and what does it tell you in terms of the problem?
3.1 feet; The value means the furthest the ball went.
3.875 feet; The value means that a typical throw of the ball results in 3.875 feet.
4.1 feet; The value means this measurement had the most occurrences.
4.65 feet; The value means that a typical throw of the ball results in 4.65 fe
The mean distance that the ball was thrown is approximately 38.92/12 = 3.24 feet.
Ball throwing distancesTo find the mean distance that the heavy ball was thrown, we need to calculate the sum of all the distances and then divide by the total number of throws:
(20+25+25+31+33+34+41+41+45+50+56+67)/12 = 467/12 ≈ 38.92
So, the mean distance that the ball was thrown is approximately 38.92/12 = 3.24 feet.
This means that on average, the ball was thrown a distance of 3.24 feet. However, it's important to note that the mean can be influenced by outliers, which in this case is the one throw of 6.7 feet.
So, while the mean is a useful measure of central tendency, it's important to also consider other measures such as the median and mode to get a complete picture of the data.
The mean is the sum of all the values in a dataset divided by the total number of values. It provides an estimate of the central location of the data and can be a useful summary statistic for describing a dataset. However, the mean can be influenced by outliers, which are values that are significantly different from the rest of the data.
In this case, the one throw of 6.7 feet is an outlier because it is much further than any other throw, and it will increase the mean value.
For this reason, it's important to consider other measures of central tendency such as the median and mode. The median is the middle value in a dataset, and it's not affected by outliers. The mode is the value that appears most frequently in a dataset and can provide useful information about the typical or most common value in the data.
By considering all three measures (mean, median, and mode), we can get a more complete picture of the data and make better inferences or conclusions about it.

If the length of minor arc ab is 12 feet and the radius of the circle is 10 feet, find the measure of the central angle subtended by minor arc ab, to the nearest degree.
The measure of the central angle subtended by minor arc ab, to the nearest degree is 67.
A minor arc is a part of a circle that is created by two points on the circumference of the circle.
To find the measure of the central angle subtended by the minor arc ab, we need to use the formula for the circumference of a circle, which is C = 2πr. The length of the minor arc ab is 12 feet, which is a part of the circumference of the circle. So, we can write an equation:
12 = C * (arc ab / C)
where C is the circumference of the circle and arc ab is the length of minor arc ab. We know that the radius of the circle is 10 feet, so we can find the circumference of the circle using the formula for circumference:
C = 2πr = 2π * 10 = 20π
Substituting the value of C in the equation above, we get:
12 = 20π * (arc ab / 20π)
Dividing both sides of the equation by 20π, we get:
12 / 20π = (arc ab / 20π)
We can now find the central angle subtended by the minor arc ab by using the formula:
Central angle = 2 * arctan(arc ab / 2r)
Substituting the values, we get:
Central angle = 2 * arctan(12 / (2 * 10)) = 2 * arctan(0.6)
Using a calculator, we can find that the value of arctan(0.6) is about 33.7 degrees. Hence, the central angle subtended by minor arc ab is:
Central angle = 2 * 33.7 = 67.4 degrees
Rounding off to the nearest degree, we get that the central angle subtended by minor arc ab is 67 degrees.

Is the union of countably infinite sets countable?
The answer is that it depends on the specific countable sets being considered and how they are being combined.
The union of countably infinite sets can be countable, as in the case of the union of all positive integers and all negative integers, which is also countable.
However, the union of countably infinite sets can also be uncountable. For example, consider the union of all the intervals [n, n+1) for n = 1, 2, 3, .... Each of these intervals is countable (since it contains all the real numbers between two integers, which is a countable set), but the union of these intervals is the uncountable set of all real numbers greater than or equal to 1. Therefore, the union of these countably infinite sets is uncountable.
So the answer is that it depends on the specific countable sets being considered and how they are being combined.

Group of answer choices

$30
The cost when the two plans cost the same for a set number of minutes is $36. Option C is correct.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Plan A costs $30 plus an additional $0.03 for each minute of calls.
This can be expressed in equation as
y=30+0.03x
Plan B has no initial fee but costs $0.18 for each minute of calls.
y=0.17x
Now we have to find the cost when the two plans cost the same for a set number of minutes
30+0.03x=0.18x
30=0.18x-0.03x
30=0.15x
Divide both sides by 0.15
x=200
when the number of minutes of calls is 200, the two plans cost the same.
To find the cost when the two plans cost the same,
we can substitute x = 200 into either expression for Cost_A or Cost_B:
Cost_A = 30 + 0.03(200) = $36
Cost_B = 0.18(200) = $36
Therefore, the cost when the two plans cost the same for a set number of minutes is $36. Option C is correct.

The answers are a) OL = 46.2, CT = 92.4, ST = 41 and LT = 46.2
b) parallelogram ABCD is a rectangle.
What is a rectangle?A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon that has four angles, equal to 90 degrees. A rectangle is a two-dimensional shape.
a) Given that, the flag of Scotland is a rectangle with white stripes as the diagonals. In rectangle SCOT, SO = 92.4, and CO = 41.
We need to find the measure of CT, OL, ST and LT,
We know that, the diagonals of a rectangle bisects each other and are congruent, and its opposite sides are equal,
Therefore,
OL = SO/2 = 92.4/2 = 46.2
CT = SO = 92.4
ST = CO = 41
LT = OL = 46.2
b) Given are vertices of parallelogram, A(-6, -2), B(-3, 3), C(2, 0), D(-1, -5), we need to verify if this is a rectangle or not,
Since, the diagonals of a rectangle are congruent, so, we will find AC and BD and see if they equal or not if equal then it is a rectangle.
Distance between two points is =
D = [tex]\sqrt{(x_{2}-x_1)^2+(y_2-y_1)^2 }[/tex]
AC = √(2+6)²+(2)² = √68
BD = √(-1+3)²+(-5-3)² = √68
∵ AC = BD, therefore, parallelogram ABCD is a rectangle.

The length of a rectangle is represented by the function L(x) = 2x. The width of that same rectangle is represented by the function W(x) = 8x2 − 4x + 1. Which of the following shows the area of the rectangle in terms of x?
(L + W)(x) = 8x2 − 2x + 1
(L + W)(x) = 8x2 − 6x + 1
(L ⋅ W)(x) = 16x3 − 4x + 1
(L ⋅ W)(x) = 16x3 − 8x2 + 2x
Answer:
Step-by-step explanation:
The area of a rectangle is given by the product of its length and width. Therefore, the area of the rectangle is:
A(x) = L(x) ⋅ W(x) = 2x(8x^2 - 4x + 1)
Simplifying the expression, we get:
A(x) = 16x^3 - 8x^2 + 2x
Therefore, the answer is (D) (L ⋅ W)(x) = 16x3 − 8x2 + 2x.
