The table below gives the probability density of trees in a particular park. If a tree is selected at random, what is the probability that it is an elm or oak?
Answers
The probability of selecting an elm or oak tree is 0.38.
The probability of selecting an elm or oak tree is the sum of the probabilities of selecting an elm and selecting an oak:
P(elm or oak) = P(elm) + P(oak)
P(elm) = 0.04
P(Oak) =0.34
Plug in these values
= 0.04 + 0.34
= 0.38
Therefore, the probability of selecting an elm or oak tree is 0.38.

Express the second quantity as a percentage of the first: (a) 10 kilograms, 105 grams (b) 8 meters, 1 kilometer
Answers
(a) As a percentage, 105 grams is 1.04% of 10 kilograms.
(b) As a percentage 1 kilometer is approximately 99.21% of 8 meters.
How to Express a Quantity as a Percentage of another?(a) To express the second quantity, 105 grams, as a percentage of the first quantity, 10 kilograms, we first need to convert both quantities to the same unit.
10 kilograms is equal to 10,000 grams (since 1 kilogram = 1000 grams), so:
10,000 grams + 105 grams = 10,105 grams
105 grams / 10,105 grams * 100% = 1.04%
Therefore, 105 grams is 1.04% of 10 kilograms.
(b) To express the second quantity, 1 kilometer, as a percentage of the first quantity, 8 meters, we first need to convert both quantities to the same unit.
1 kilometer is equal to 1000 meters (since 1 kilometer = 1000 meters), so:
8 meters + 1000 meters = 1008 meters
1000 meters / 1008 meters * 100% = 99.21%
Therefore, 1 kilometer is approximately 99.21% of 8 meters.

Answers
m = (y2 - y1) / (x2 - x1)
Substituting the given values, we get:
m = (-2 - (-4)) / (-1 - 7) = 2/8 = 1/4
Now that we have the slope, we need to find the y-intercept of the line, which is denoted by 'b'. We can use the slope-intercept form of a line, which is:
y = mx + b
where m is the slope and b is the y-intercept.
To find b, we can use one of the given points. Let's use (7, -4):
-4 = (1/4)(7) + b
-4 = 7/4 + b
b = -4 - 7/4
b = -23/4
Now we have the slope and y-intercept, so we can write the equation of the line in slope-intercept form:
y = mx + b
y = (1/4)x - 23/4
Therefore, the correct answer is: y = (1/4)x - 23/4.

Consider the quadratic function f(x) = 1/5x2 – 5x + 12. Which statements are true about the function and its graph? Select three options. The value of f(–10) = 82 The graph of the function is a parabola. The graph of the function opens down. The graph contains the point (20, –8). The graph contains the point (0, 0).
Answers
The three statements that are true about the function and its graph are:
The graph of the function is a parabola.
The graph opens downwards, since the coefficient of x² is positive.
The graph contains the point (0, 12), which can be obtained by substituting x=0 in the function.
To check the other statements:
What is the value of f(–10) = 82?To find f(-10), we substitute x=-10 in the function:
f(-10) = 1/5*(-10)² - 5*(-10) + 12 = 82. So the statement "The value of f(–10) = 82" is true.
To check if the graph contains the point (20,-8), we substitute x=20 in the function:
f(20) = 1/5*(20)² - 5*(20) + 12 = -68. This means the point (20,-8) does not lie on the graph of the function.
To check if the graph contains the point (0,0), we substitute x=0 in the function:
f(0) = 1/5*(0)² - 5*(0) + 12 = 12. This means the point (0,0) does not lie on the graph of the function.

Step-by-step explanation:
angle b= 63
Ac= 23.6
Ab=26.4
Angle B is 63 degrees, the length of AC is approximately 22.23 units, and the length of AB is approximately 26.42 units.
What is right angle triangle?
A triangle in which one of its angles measures 90 degrees is called a right-angled triangle .
The side opposite the right angle is called the hypotenuse while the other two sides are called the legs or the adjacent and opposite sides.
According to given figure angle C is a right angle, we know that the sum of angles A and B must be 90 degrees.
So, angle B = 90 - angle A = 90 - 27 = 63 degrees.
To find the length of AC, we can use trigonometry. Since we know the length of the opposite side (BC) and the angle opposite the side we want to find (angle A), we can use the tangent function:
tan A = opposite / adjacent
tan 27 = BC / AC
AC = BC / tan 27
AC = 12 / tan 27
AC ≈ 22.23
Now,
[tex]AB^2 = AC^2 + BC^2 \\ AB^2 = 22.23^2 + 12^2 \\ AB^2 ≈ 697.57 \\ AB ≈ 26.42[/tex]

Answers
S_n = a(1 - r^n) / (1 - r)
In this case, we have n sticks in total, so we need to calculate S_n with n:
S_n = a(1 - 2^n) / (1 - 2)
S_n = a(2^n - 1)
Therefore, the combined length of the sticks in Martin's pattern is closest to (2^n - 1) multiplied by the length of the shortest stick.

Answers
It should be noted that 49.87% of the values fall between 19 and 34 in the original normal distribution.
How to calculate the percentageFor the lower bound of 19, the z-score is:
z = (19 - 19) / 5 = 0
For the upper bound of 34, the z-score is:
z = (34 - 19) / 5 = 3
Looking up the area under the curve for a z-score of 3 in a standard normal distribution table, we find it to be 0.9987. Looking up the area under the curve for a z-score of 0, we find it to be 0.5. Therefore, the area under the curve between z-scores of 0 and 3 is:

if tan68° = 1/m, express the following in terms of m:
1. tan22°
Answers
tan(3 * 22°) = (3tan22° - tan^3(22°)) / (1 - 3tan^2(22°))
Solving for tan(22°), we get:
tan(22°) = (3tan(3 * 22°) - tan^3(3 * 22°)) / (3tan^2(3 * 22°) - 1)
Now, using the identity tan(3θ) = (3tanθ - tan^3θ) / (1 - 3tan^2θ), we can also say that:
tan(3 * 68°) = (3tan68° - tan^3(68°)) / (1 - 3tan^2(68°))
Given that tan68° = 1/m, we can substitute this value into the equation above to get:
tan(3 * 68°) = (3/m - 1/m^3) / (1 - 3/m^2)
Simplifying this expression, we get:
tan(3 * 68°) = (3 - m^2) / (m^3 - 3m)
Now, substituting the value of tan(3 * 22°) = (3 - √3) / (3√3 - 1) into the equation for tan(22°), we get:
tan(22°) = (3(3 - √3)/(3√3 - 1) - (3 - √3)^3/(3√3 - 1)^3) / (3(3 - √3)/(3√3 - 1)^2 - 1)
Simplifying this expression, we get:
tan(22°) = (27 - 9√3 - 27√3 + 9√3) / (27√3 - 9 - 3√3 + 1)
tan(22°) = (18 - 18√3) / (26√3 - 8)
Therefore, we can express tan(22°) in terms of m as:
tan(22°) = (18 - 18√3) / (26√3
tan(68° - 46°) = (tan 68° - tan 46°)/(1 + tan 68° * tan 46°)
tan 22° = (tan 68° - tan 46°)/(1 + tan 68° * tan 46°)
We know that tan 68° = 1/m, so we can substitute:
tan 22° = (1/m - tan 46°)/(1 + (1/m) * tan 46°)
Therefore, tan 22° can be expressed in terms of m as:
tan 22° = (1/m - tan 46°)/(1 + tan 46°/m)

Answers
The probability that the employee will arrive between 8:05 a.m. and 8:45 a.m. is 0.8, or 80% when expressed as a percentage.
HOW TO SOLVE THE PROBABILITY ?To find the probability that the employee will arrive between 8:05 a.m. and 8:45 a.m., we need to calculate the proportion of the total possible time range between 8:00 a.m. and 8:50 a.m. that falls within the specified time interval.
The total time range between 8:00 a.m. and 8:50 a.m. is 50 minutes (8:50 - 8:00 = 50). The time interval between 8:05 a.m. and 8:45 a.m. is 40 minutes (8:45 - 8:05 = 40).
So, the probability that the employee will arrive between 8:05 a.m. and 8:45 a.m. is:
Probability = (Time interval between 8:05 a.m. and 8:45 a.m.) / (Total time range between 8:00 a.m. and 8:50 a.m.)
Probability = 40 minutes / 50 minutes
Probability = 0.8
Therefore, the probability that the employee will arrive between 8:05 a.m. and 8:45 a.m. is 0.8, or 80% when expressed as a percentage.

What is over the interval?To determine over what interval f(x) = 2x increases faster than g(x) = x^2, we need to compare their derivatives. The derivative of f(x) is 2, which is a constant, and the derivative of g(x) is 2x. Therefore, f(x) increases at a constant rate of 2, while g(x) increases at a rate that depends on x.
To find the interval where f(x) increases faster than g(x), we need to find where the derivative of g(x) is less than 2. Setting 2x < 2 and solving for x, we get x < 1.

Answers
H 48 feet could be the perimeter of Rebecca's garage door.
We know,
Perimeter is the distance around a two-dimensional shape. It is measured in units of length, such as feet or inches.
Rebecca found the length and width of the garage door, which are both measurements of length. Let's say she found that the length was 8 feet and the width was 6 feet.
To find the perimeter, she would add up the lengths of all four sides of the rectangle:
Perimeter = 2(length) + 2(width)
Perimeter = 2(8 feet) + 2(6 feet)
Perimeter = 16 feet + 12 feet
Perimeter = 28 feet
So the perimeter of Rebecca's garage door is 28 feet. None of the answer choices given match this value exactly, but H 48 feet is a possible perimeter if the garage door was much larger than the example given above. However, it is important to note that the term "cubic feet" (answer choice J) does not apply to perimeter, as cubic feet is a unit of volume and not length.

Using the conversion factor we know that we will spend 180.69€ on memorabilia items.
What is the conversion factor?A conversion factor is a number that is used to multiply or divide one set of units into another.
If a conversion is required, it must be done using the correct conversion factor to get an identical value.
A fraction that is equal to "1" is a conversion factor.
The numerator and denominator are the same amounts, but they are expressed in different units. It is used to change a number's unit of measurement.
By multiplying the initial number by the fraction that is equal to "1," you can change the units without changing the original number's value.
So, in the given situation:
$200 = euros?
We know that:
$1 = 0.90€
