Why is the standard deviation of the distribution of means generally smaller than the standard deviation of the population of individuals?
The standard deviation of the distribution of means is generally smaller than the standard deviation of the population of individuals.
What is the standard deviation?The standard deviation mathematical and statistical analysis tool used to explain the diversity of treatments or values around the Mean is the standard deviation, which is also known as the square root of variance.
The population of individuals is always smaller than the entire population, therefore the possibilities for variances will be lower with the sample than with the population. The higher the population, the greater the chances for deviation from the mean.
Therefore, the standard deviation of the distribution of means is generally smaller than the standard deviation of the population of individuals.

5r+5= 3(5r - 4) – 10r
Answer: No solution
Step-by-step explanation:
5r + 5 = 3(5r - 4) - 10r Do multiplication
5r + 5 = 15r - 12 - 10r combine like terms
5r + 5 = 5r - 12 This is impossible. 5r cannot equal 5 and 12 meaning there is no value of r that makes this equation true so there's No Solution.

Find the equation of a line that passes through the point (1, -5) and is perpendicular to a line that passes through the points (2, 4) and (3, -4). Write the equation in slope intercept
form.
The equation of a line in slope-intercept form is [tex]y = \frac{1}{8} x - \frac{41}{8}[/tex] .
What is slope intercept form?One of the most popular ways to represent a line's equation is in the slope-intercept form of a straight line.When the slope of the straight line and the y-intercept are known, the slope-intercept formula can be used to determine the equation of a line ( the y-coordinate of the point where the line intersects the y-axis).The equation of the line is given below using the slope-intercept method:
y = mx + c
where,
m = the slope of the line
c = y-intercept of the line
(x, y) represent any point on the line
To find the Slope of a line that passes through the points (2, 4) and (3, -4).
m₁ = change in y/change in x
= y₂ - y₁ / x₂ - x₁
= Δy/Δx
= [tex]\frac{-4-4}{3-2}[/tex]
= [tex]\frac{-8}{1}[/tex]
= -8
Now, we find the slope of the line perpendicular to the line with the slope -8.
m₂ = -1 / m₁
= -1 / -8
= 1/8
So, the slope of the line is 1/8.
Next, we find the equation of a line that passes through the point (1, -5) and has a slope of 1/8.
⇒ y - y₁ = m( x- x₁)
⇒ y + 5 = [tex]\frac{1}{8}[/tex] (x - 1)
Multiplying by 8 on both sides of the equation we get and then solving
⇒ 8y + 40 = x - 1
⇒ 8y = x - 41
⇒ [tex]y = \frac{1}{8} x - \frac{41}{8}[/tex]
Therefore, the equation in slope intercept form is [tex]y = \frac{1}{8} x - \frac{41}{8}[/tex] .

square feet, determine the length of the base and the height of the triangle in feet.
foot
The length of both the triangle's base and height in feet.
length of base = 32ft
height = 14 ft.
The triangle's base and height:The base of a triangle can be any of its sides. The term "base" refers to the both the side and the length (the measurement). The comparable height is really the length of a perpendicular segment from either the base to the opposing vertex.
According to the given data:Given that perhaps the cross-section of the lean-to shelter is a triangle, its area is a triangle.
A = ¹/₂bh
b = length of base
h = height
the base of the triangle is 10 feet more than twice its height, we have that
b = 2h + 10
A = ¹/₂bh
A = ¹/₂(2h + 10)h
A = h² + 5h
Since the area of the triangle is A = 126 ft², we have that;
h² + 5h = 126
h² + 5h - 126 = 0
h² +(14h -9h) - 126 = 0
h² +14h -9h - 126 = 0
h(h + 14) -9(h + 14) = 0
(h + 14)(h - 9) = 0
Hight cant be negative:
h = 14
Length of the base is b = 2h + 10
b = 2h + 10
b = 2(14) + 10

Answer:
∠ A = 42° , ∠ G = 85°
Step-by-step explanation:
the measure of an inscribed angle is half the measure of its intercepted arc.
(3)
∠ A is an inscribed angle , so
∠ A = [tex]\frac{1}{2}[/tex] BC = [tex]\frac{1}{2}[/tex] × 84° = 42°
(4)
∠ G is an inscribed angle but we require arc DF
the sum of the arcs in a circle = 360°
FG + GD + FD = 360°
70° + 120° + FD = 360°
190° + FD = 360° ( subtract 190° from both sides )
FD = 170°
Then
∠ G = [tex]\frac{1}{2}[/tex] DF = [tex]\frac{1}{2}[/tex] × 170° = 85°

What is the Slope of a Line?The slope of a line, commonly known as the gradient, is defined as the value of the steepness or direction of a line in a coordinate plane. Slope can be determined using many ways given the equation of either a line or the coordinates of points on the straight line. . The slope is defined mathematically as "climb overrun" (change in y divided by change in x).
According to the given data:x₁ = 1
y₁ = 7
x₂ = -3
y₂ = -1
To obtain the equation of a line, we must first determine its slope. This is computed as:
m = [y₂ - y₁ ]/[x₂ - x₁]
Substituting the value we get:
m = [(-1) - 7 )/((-3) - 1)]
= -8/-4
= 2
The slope of the line = 2.

$19.75
$19.82
$20.45
$21.13
The total money that will be cost for Mrs. Herrera to purchase candy for her is $10.9889
Given, Number of students that 100% attendance in the class is √196 -1 that is equal to
