How do you calculate the range?
A range is calculating by subtracting the smallest value from the largest value as range from 1 to 5 is 4.
Why do we calculate the range?Utilizing the same units as the data, it measures variability. Greater variability is shown by larger values. The range is the simplest statistical measure of dispersion to compute and explain, but it has significant restrictions.
What is a range of numbers?The difference between a collection of numbers' highest and lowest values is known as the range. Subtract the distribution's lowest number from its greatest number to determine it.
Find the biggest observed value of a variable (the maximum) and subtract the smallest observed value to determine the range (the minimum). The data points between the distribution's two extremes are not taken into account by the range; it only considers these two values.
suppose we have a set of values
22,56,43,87,33,12,11

A convex lens with focal length f centimeters will project the image of an object on a
point behind the lens. If an object is placed a distance of p centimeters from the lens,
then the distance q centimeters of the image from the lens is related to p and f by the
lens equation: 1/p+1/q=1/f
A. If the focal length of the convex lens is supposed to be 5 cm, and if the image is
formed 7 cm from the lens, find the distance from the lens to the object, p. (It’s not necessary to simplify your answer.)
B. Find an expression that gives q as a function of p, assuming that the focal length is a constant of 5 centimeters.
C. Sketch a graph of q as a function of p (i.e., q(p)), assuming that the focal length is a
constant of 5 centimeters. Show any important features of the graph.
D. Find limq(p) as p approaches infinity and limq(p) as p approaches 5from the positive side. What do these limits represent physically? What must
happen to the distance of the image and the object?
Answer:
A. Using the lens equation, 1/p + 1/q = 1/f, and substituting f = 5 cm and q = 7 cm, we can solve for p:
1/p + 1/7 = 1/5
Multiplying both sides by 35p, we get:
35 + 5p = 7p
Simplifying and rearranging, we get:
2p = 35
Therefore, the distance from the lens to the object, p, is:
p = 35/2 cm
B. Solving the lens equation, 1/p + 1/q = 1/f, for q, we get:
1/q = 1/f - 1/p
Substituting f = 5 cm, we get:
1/q = 1/5 - 1/p
Multiplying both sides by 5qp, we get:
5p = qp - 5q
Simplifying and rearranging, we get:
q = 5p / (p - 5)
Therefore, the expression that gives q as a function of p is:
q = 5p / (p - 5)
C. Here is a sketch of the graph of q(p):
The graph is a hyperbola with vertical asymptote at p = 5 and horizontal asymptote at q = 5. The image distance q is positive for object distances p greater than 5, which corresponds to a real image. The image distance q is negative for object distances p less than 5, which corresponds to a virtual image.
D. Taking the limit of q as p approaches infinity, we get:
lim q(p) = 5
This represents the horizontal asymptote of the graph. As the object distance becomes very large, the image distance approaches the focal length of the lens, which is 5 cm.
Taking the limit of q as p approaches 5 from the positive side, we get:
lim q(p) = -infinity
This represents the vertical asymptote of the graph. As the object distance approaches the focal length of the lens, the image distance becomes infinitely large, indicating that the lens is no longer able to form a real image.
In order for the lens to form a real image, the object distance p must be greater than the focal length f. When the object distance is less than the focal length, the lens forms a virtual image.

\(\huge\boxed{\sf x =6,\ y = 42}\)
Step-by-step explanation:
Let the numbers be x and y
Given condition:x + y = 48 --------(1)
y = 7x -------------(2)
Put Eq. (2) in (1)
x + 7x = 48
8x = 48
Divide 8 to both sides
x = 48/8
x = 6Put x = 6 in Eq. (2)
y = 7 (6)
y = 42\(\rule[225]{225}{2}\)
Assume a is the 1st number and b is the 2nd number, a + b = 48
b = 7a (the second number is seven times the first number)
a = a
So, equation: a + 7a = 48
a + 7a = 48
8a = 48
a = 6
To find b = 7 (6) = 42

identify a major league ballpark in which the distance from home plate to the center field
fence and the height of the center field fence require that a ball hit 2 ft above the ground will
necessitate an angle of elevation less than 0.86 to just clear the center field fence. The
ballpark you will identify today is known as "Comersia Park "aka the home of the Detroit
tigers. The distance between the Homeplate to the center field fence is 420 ft. however the
center field fence height is 9ft. make sure to find out the elevation and velocity?
Answer:
first off the park you've listed is no match for the fact its more then 0.86.
Step-by-step explanation:
\(tan^{-1} (\frac{7}{420} )\\\\= arctan (\frac{7}{420} )\\\\= arctan (\frac{1}{60} )\\= 0.95\)
so basically it equals 0.95°
which basically means 0.86 < 0.95.

\(80,68,77\)We are required to determine the following:
• Mean
,• Median
- First, we arrange the data given in ascending (least to greatest) order. We have:
\(68,77,80\)We know that the mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.
Therefore, we have:
\(\begin{gathered} Mean=\frac{68+77+80}{3} \\ Mean=\frac{225}{3} \\ Mean=75 \end{gathered}\)Hence, the mean is:
\(Mean=75\)Also, we know that the median is the middle number in a sorted, ascending or descending, list of numbers.

Solution
Given the equation
\(y=-\frac{5}{4}x+\frac{11}{4}\)Here, the radient is;
\(m=-\frac{5}{4}\)Since the line in question is perpendicular to the given line,
The product of their gradient mst be -1
\(\begin{gathered} m_1\times m=-1 \\ \\ \Rightarrow m_1=-\frac{1}{m} \\ \\ \text{ since }m=-\frac{5}{4} \\ \\ \Rightarrow m_1=-\frac{1}{-\frac{5}{4}}=\frac{4}{5} \end{gathered}\)Therefore, the gradient of the line in questin is 4/5
Since the line passes trough the poinyt (0, 7)
\(\begin{gathered} \Rightarrow\frac{y_-y_1}{x-x_1}=m \\ \\ \Rightarrow\frac{y-7}{x-0}=\frac{4}{5} \\ \\ \Rightarrow\frac{y-7}{x}=\frac{4}{5} \\ \\ \Rightarrow y-7=\frac{4}{5}x \\ \\ \Rightarrow y=\frac{4}{5}x+7 \end{gathered}\)Hence, the correct option is A.

Answer:
Step-by-step explanation:
the degree of a polynomial determines 1:1 the number of solutions.
a quadratic equation (degree 2) has 2 solutions.
the general solution is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = -4
b = -4
c = -1
so,
x = (4 ± sqrt((-4)² - 4×-4×-1))/(2×-4)
when we look at the square root
16 - 16
we see that it is 0.
the square root of 0 is 0, and there is no difference between -0 and +0.
so, we get only one (real) solution : 4/-8 = -1/2

Slope 3/5 yintercept2 write an equation slope-intercept form
The equation of the line in slope-intercept form is y = (3/5)x + 2. This form allows us to easily identify the slope and y-intercept of the line and to graph it on a coordinate plane.
To write the equation of a line in slope-intercept form, we use the formula:y = mx + b
where:
- y represents the dependent variable (the vertical axis)
- x represents the independent variable (the horizontal axis)
- m represents the slope of the line
- b represents the y-intercept, the point where the line intersects the y-axis.
In this case, we are given the slope as 3/5 and the y-intercept as 2. Plugging these values into the formula, we get:
y = (3/5)x + 2
This equation represents a line with a slope of 3/5, indicating that for every 5 units we move horizontally (along the x-axis), the line moves 3 units vertically (along the y-axis). The y-intercept of 2 tells us that the line intersects the y-axis at the point (0, 2).

Step-by-step explanation:
Triangle ABC is a right angle triangle.
From the given right angle triangle,
AB represents the hypotenuse of the right angle triangle.
With m∠A as the reference angle,
AC represents the adjacent side of the right angle triangle.
BC represents the opposite side of the right angle triangle.
To determine tan m∠A, we would apply the tangent trigonometric ratio.
Tan θ = opposite side/adjacent side. Therefore,
Tan A = √32/2 = (√16 × √2)/2
Tan A = (4√2)/2
Tan A = 2√2

Solve for x.
x+6= √2x+29 +9
The solution to the equation is x = 10 or x = -2.
What is an equation?An equation refers to a mathematical expression showing that two expressions are equal.
It must have variables (e.g. a, c, x, y), constants (like 1, 13, 50, etc), and mathematical operations (like +, -, *, /).
To solve for x, we shall start with the given equation:
x + 6 = √(2x + 29) + 9
Subtract 9 from both sides:
x - 3 = √(2x + 29)
Square both sides:
\((x - 3)^2\) = 2x + 29
Expand the left side:
\(x^2\) - 6x + 9 = 2x + 29
We then subtract 2x and 9 from both sides:
\(x^2\) - 8x - 20 = 0
Next, actor the quadratic equation:
(x - 10)(x + 2) = 0
