To determine her breathing rate, Miranda divides up her day into three parts: morning, afternoon, and evening. She then measures her breathing rate at 4 randomly selected times during each part of the day. What type of sampling is used? A. Simple random B, Stratified C. Systematic D. Convenience E. Cluster
The type of sampling used in this scenario is B. Stratified sampling. Stratified sampling involves dividing the population into distinct subgroups or strata and then selecting samples from each subgroup.
In this case, Miranda divides her day into three parts: morning, afternoon, and evening. Each part of the day represents a stratum or subgroup. Miranda measures her breathing rate at 4 randomly selected times during each part of the day. This means she is taking samples from each of the three strata (morning, afternoon, and evening) and collecting data from within those subgroups.
By using stratified sampling, Miranda ensures that her samples represent the different parts of her day in a proportional and systematic manner, allowing her to capture potential variations in her breathing rate throughout the day.

Use the slope formula to find the slope of the line passing through the points (−5,4) and (5,0). Use pencil and paper. Find two more points that the line passes through.
The slope of the line is nothing. (Type an integer or a simplified fraction.)
Answer:
Slope = -2/5 new points (5/2,1) and (5,0)
Step-by-step explanation:
Standard point slope equation:
y = mx + b where m is the slope and b is the y-intercept.
First find the slope between the given points.
Slope = rise/run
m = (y1 - y2) / (x1 - x2)
= (4 - 0)/(-5 - 5)
= 4/-10 = -2/5 then
y = (-2/5)x + b then one point (I picked (-5,4) to find b
4 = (-2/5)(-5) + b
4 = 2 + b
b = 2
y = (-2/5)x + 2 then pick an x and find y for additional points.
x = 5/2
y = (-2/5)(5/2) + 2
y = -1 + 2
y = 1 so the point is (5/2,1) and let x = 5
y = (-2/5)(5) + 2
y = -2 + 2
y = 0 so the point is (5,0)
Suppose that :
A = ( 5 , 0 )
B = ( - 5 , 4 )
Then we have :
Slope = [ y(B) - y(A) ] ÷ [ x(B) - x(A) ]
Slope = [ 4 - 0 ] ÷ [ -5 - 5 ]
Slope = 4 ÷ ( - 10 )
Slope = - 4/10
Slope = - 2/5
________________________________
It's time to find the formula of this linear function using following formula :
y - y ( A or B ) = Slope × ( x - x ( A or B ) )
I'm gonna using point A but u can do it with point B which will gave the same answer :
y - 0 = - 2/5 × ( x - 5 )
y = - 2/5 x + 2
_______________________________
We have the formula of the function now thus it's time to find two more points that line passe through ;
To do that we just have to put two desired values of x instead of it and find the y to have the coordinate of those points that line passes through :
I'm gonna use x = - 10 and x = 15 :
x = - 10 x = 15
y = - 2/5 × ( -10 ) + 2 y = -2/5 × ( 15 ) + 2
y = 4 + 2 y = - 6 + 2
y = 6 y = - 4
________________________________
Thus ( -10 , 6 ) & ( 15 , - 4 ) are two other points that line passes through.
For the function f(x) = 4x – 6, find x if f(x) = 22

Write the equation of the line in slope-interpret form. Explain
Answer:
y = -½x + 4
Step-by-step explanation:
Equation of any line in slope-intercept form is y = mx + b, where,
m = slope = change in y/change in x
b = y-intercept = the point on the y-axis intercepted by the line.
Let's find m and b.
✔️Using two points on the line, (0, 4) and (2, 3),
Slope (m) = change in y/change in x = (3 - 4)/(2 - 0)
m = -1/2 = -½
✔️The line intercepts the y-axis at y = 4.
Therefore,
b = 4
✔️To write the equation of the line, substitute m = -½ and b = 4 into y = mx + b.
Thus,
y = -½x + 4

Somebody pls!! “Write the equation of the line in fully simplified slope-
intercept form.”
Answer:
y = 3/5x + 5
Step-by-step explanation:
Slope-intercept form is y = mx + b where m is the slope (rise / run of the line) and b is y-intercept (y value of where the line intersects with the y-axis.
The line is rising up 3 and run to the right 5 and so it's slope is 3/5. The line intersects with the y-axis at a y value of 5 and so it's y-intercept is 5.
Therefore, your answer in slope-intercept form is y = 3/5x + 5.

remember that we don't consider degenerate triangles unless specially instructed otherwise. two side lengths of a triangle are and . what is the longest possible integer length of the third side of the triangle?
The minimum value of the third side is 9 cm, and The maximum value of the third side is 6.7 cm.
The minimum value of the third side is when the triangle is a degenerate triangle, meaning that the third side is a line segment joining the two endpoints of the first two sides, which is equal to 3 cm + 6 cm = 9 cm.
The maximum value of the third side is when the triangle is a right triangle, and the two sides are the legs. According to the Pythagorean theorem, the third side (the hypotenuse) should be equal to the square root of 3² + 6² = 9 + 36 = 45, which is equal to 6.7 cm.

There are so many items for sale in our world! Some of the items you can buy will appreciate in value. This means that as time passes, the value of the item increases. If you decide to sell the item at a later time, you should be able to sell it for more than you paid. Some common examples of items that appreciate in value include houses, stocks, and some types of art.
Other items you can buy will depreciate in value. This means that as time passes, the value of the item decreases. If you decide to sell the item at a later time, you will likely have to sell it for less than you paid for it. Cars, game systems, and jewelry are examples of items that usually depreciate as time passes. The majority of items that depreciate never reach a value of $0. Their worth attains some minimum, positive value that is greater than $0 and then their price stabilizes.
In 1981, IBM manufactured and sold one of the first personal computers. The machine was called the IBM Personal Computer (PC) 5150 and the full model retailed for $3,000. Similar to modern technology, the value of this item depreciated over time. The function that models how the PC 5150 depreciated as time passed is , where x is the number of years after 1981 and f(x) is the value of the PC 5150.

A system will function if exactly 3 out of 5 componet function with probability of functioning 0.9. The probability the system will function is equals to the 0.9914.
Binomial distribution is a probability distribution used in statistics that defines as a value will take one of two independent values under a set of parameters or assumptions. Formula, P ( X = x)
= nⁿCₓ pˣ(1 -p)⁽ⁿ⁻ˣ⁾
where, P -->binomial probability
x --> number of times for a n trialsⁿCₓ= number of combinationsp --> probability of success on a single trial1- p --> probability of failure on a single trialn--> number of trialsWe have provided that k out of n system is one which have a group of n components and system will function atleast k of components. Also, consider that components function independently of one another. So, The distribution of the number of components functioning is Binomial, X ~ Binom( n,p).
Probability of functioning of each component in 3 out of 5 system = 0.9
that is Probability of success, p = 0.9 and n = 5.
Now for the system to function at least 3 components must function.
X ~ Binom( 5,0.9)
a) The probability the system will function is determined by using binomial probability formula,
P (X ≥ 3) = 1 - P (X < 3)
= 1 - P (X = 0) - P (X = 1) - P (X = 2)
= 1 - ⁵C₀ 0.9⁰ ( 1-0.9)⁵ - ⁵C₁ 0.9¹ ( 1-0.9)⁴ - ⁵C₂ 0.9²(1 -0.9)³

, (b) A = B = C = 1 and ( c) A = B = C = 0.
The given expressions, when A=1, B=0, and C=1, X evaluates to 1.001; when A=B=C=1, X evaluates to 1.111; and when A=B=C=0, X evaluates to 0.000. These evaluations are based on the given values of A, B, and C, and the notation ¯¯¯¯¯¯BC represents the complement of BC.
To evaluate the expression X = A.¯¯¯¯¯¯BC, we substitute the given values of A, B, and C into the expression.
(a) For A = 1, B = 0, and C = 1:
X = 1.¯¯¯¯¯¯01
To find the complement of BC, we replace B = 0 and C = 1 with their complements:
X = 1.¯¯¯¯¯¯01 = 1.¯¯¯¯¯¯00 = 1.001
(b) For A = B = C = 1:
X = 1.¯¯¯¯¯¯11
Similarly, we find the complement of BC by replacing B = 1 and C = 1 with their complements:
X = 1.¯¯¯¯¯¯11 = 1.¯¯¯¯¯¯00 = 1.111
(c) For A = B = C = 0:
X = 0.¯¯¯¯¯¯00
Again, we find the complement of BC by replacing B = 0 and C = 0 with their complements:
X = 0.¯¯¯¯¯¯00 = 0.¯¯¯¯¯¯11 = 0.000
In conclusion, when A = 1, B = 0, and C = 1, X evaluates to 1.001. When A = B = C = 1, X evaluates to 1.111. And when A = B = C = 0, X evaluates to 0.000. The evaluation of X is based on substituting the given values into the expression A.¯¯¯¯¯¯BC and finding the complement of BC in each case.

3-3k+7k=5b solve for x
Hey there!
\(3-3k+7k=5b\)
Assuming you're trying to solve for b or k, I'll solve both.
Solve for b:
\(3-3k+7k=5b\)
We will need to flip the equation:
\(5b=4k+3\)
Now, let's divide both sides by 5:
\(\frac{5b}{5} =\frac{4k+3}{5}\)
\(b=\frac{4}{5} k+\frac{3}{5}\)
Solve for k:
\(3-3k+7k=5b\)
Let's add -3 to both sides:
\(4k+3+-3=5b+-3\\4k=5b-3\)
Now, let's divide both sides by 4:
\(\frac{4k}{4} =\frac{5b-3}{4}\)
\(k=\frac{5}{4} b+\frac{-3}{4}\)
Now, we've solved for b and k.

consider an undirected graph that has 100 vertices. for any pair of vertices, only 1 edge can connect them. in other words, you cannot have 2 edges connecting vertex a directly to vertex b. also assume that there are no self-loops, i.e. an edge that goes from vertex a to vertex a. what is the maximum number of edges that can be in this specific graph?
So the maximum number of edges in an undirected graph with 100 vertices is 4950.
In an undirected graph, each edge connects two vertices, and as such, it is counted twice, once for each vertex it connects. Therefore, the total number of edges in the graph is the sum of the degrees of all vertices, divided by 2.
In a complete graph with n vertices, every vertex is connected to every other vertex, except itself, and so the degree of each vertex is n-1 (it is connected to n-1 other vertices). Therefore, the total number of edges in the graph is:
n * (n-1) / 2
Substituting n = 100, we get:
100 * 99 / 2 = 4950
