Answer:
B
Step-by-step explanation:
For a set of data to have a median that is greater than the mean, it must have an odd number of values and be skewed to the right. This means that the majority of the values in the set must be smaller than the median, with a few larger values on the right side of the distribution.
Out of the given options, the only set of data that satisfies these conditions is (B) {8, 12, 14, 14, 22}. This set has an odd number of values, and the median of 14 is greater than the mean of 14.4. The other options have either an even number of values, or are not skewed to the right.
Therefore, the correct answer is (B) {8, 12, 14, 14, 22}.

The traight line L ha equation 5x2y=31. The point A ha coordinate (0,1). The traight line M i perpendicular to L and pae through A. Line L croe the y-axi at the point B. Line L and M interect at the point C. Work out the area of the triangle ABC
the area of the triangle ABC is found by using the formula 1/2 * (base * height). Here, the base is 0 and the height is 1. Thus, the area of the triangle ABC = 0.5.
Let x = 0, y = 1 in 5x2y = 31
31 = 0
Thus, the point B is (0, 0).
The area of the triangle ABC = 1/2 * (0 * 1) + (0 * 1) + (1 * 0) = 0.5.
The equation of line L is given as 5x2y = 31. To find the point B, we need to substitute x = 0 in the equation. Doing so, we get 31 = 0, which means that the point B lies on the y-axis at (0, 0).
Next, since the line M is perpendicular to L and passes through A, we can assume that it is a horizontal line passing through (0, 1). Thus, the point C is the point of intersection of L and M, which is (1, 0).
Finally, the area of the triangle ABC is found by using the formula 1/2 * (base * height). Here, the base is 0 and the height is 1. Thus, the area of the triangle ABC = 0.5.

Answer: d = 0
Step-by-step explanation:
To solve this equation, we will isolate the variable.
7.5d = 2.5d
(7.5d) - 2.5d = (2.5d) - 2.5d
5d = 0
[tex]\frac{5d}{5}[/tex] = [tex]\frac{0}{5}[/tex]
d = 0
Elena is correct when she subtracts 2.5d from each side. Since subtraction is the inverse operation of addition, we need to subtract. 7.5d and 2.5 are both like terms, so we subtract the coefficents.

To solve this equation, you can use the property of equality, which states that whatever you do to one side of the equation, you must also do to the other side.
To isolate the variable "y," you can divide both sides of the equation by 4:
4y / 4 = 164 / 4
This simplifies to:
y = 41
Therefore, y equals 41.

Which of the following is/are tautology?A. a v b → b ^ cB. a ^ b → b v cC. a v b → (b → c)D. None of theseexplain please
The logical statement [tex]$(a \wedge b) \rightarrow(b \vee c)$[/tex] is a tautology. Hence, Option B is the most appropriate answer to the given question.
A tautology is a logical statement where the conclusion is always equivalent to the premise. No matter what the individual parts are, the result is always a true statement; i.e. a tautology is always true. The opposite of tautology is either a contradiction or a fallacy.
a. let us check the first option.
[tex](a \vee b) \rightarrow(b \wedge c)=(a+b)^{\prime}+b c[/tex]
[tex](a \vee b) \rightarrow(b \wedge c)=a^{\prime} b^{\prime}+b c[/tex]
Therefore, [tex]$(a \vee b) \rightarrow(b \wedge c)$[/tex] is a contingency and not a tautology.
b. let us check the second option.
[tex](a \wedge b) \rightarrow(b \vee c)=a b \rightarrow b+c[/tex]
[tex](a \wedge b) \rightarrow(b \vee c)=(a b)^{\prime}+b+c[/tex]
[tex](a \wedge b) \rightarrow(b \vee c)=a^{\prime}+b^{\prime}+b+c[/tex]
[tex](a \wedge b) \rightarrow(b \vee c)=a^{\prime}+1+c[/tex] (since, b' + b = 1)
[tex](a \wedge b) \rightarrow(b \vee c)=1.[/tex]
Therefore, [tex]$(a \wedge b) \rightarrow(b \vee c)$[/tex] is a tautology.
c. let us check the third option.
[tex](a \wedge b) \rightarrow(b \rightarrow c)=(a+b) \rightarrow\left(b^{\prime}+c\right)[/tex]
[tex](a \wedge b) \rightarrow(b \rightarrow c)=(a+b)^{\prime}+b^{\prime}+c[/tex]
[tex](a \wedge b) \rightarrow(b \rightarrow c)=a^{\prime} b^{\prime}+b^{\prime}+c[/tex]
[tex](a \wedge b) \rightarrow(b \rightarrow c)=b^{\prime}+c[/tex]
Therefore, [tex]$(a \wedge b) \rightarrow(b \rightarrow c)$[/tex] is contingency but not a tautology.
d. let us check the fourth option.

using the z table, determine the critical value for the left-tailed test with α = 0.02.
The critical value for the left-tailed test is −2.0537.
For a left-tailed test, when α=0.02, the critical z-value is the value on the horizontal axis of the z- or standard normal distribution curve such that the area under the curve to the left of this critical value is 0.02.
Using a standard normal distribution table,
Z-Score, also known as the standard score, indicates how many standard deviations an entity is, from the mean.
There are two z-score tables which are:
Positive Z Score Table: It means that the observed value is above the mean of total values.Negative Z Score Table: It means that the observed value is below the mean of total values.Now 0.5-α=0.5-0.02
=0.48
So 0.48 is closest in z score table is z=2.05

The values of v and w are 12 and 20 respectively which makes ΔPQR ≅ ΔIJK (Congruent right triangles).
When two triangles are said to be congruent?Two triangles are said to be congruent if their shape and size are the same. If two right triangles are said to be congruent, then they must have equal measures for their corresponding sides and angles.
Calculation:The given two right triangles are congruent. I.e., ΔPQR ≅ ΔIJK
So, their corresponding sides QR = IJ and PR = IK, and the corresponding angle ∠Q = ∠J.
But we have QR = w - 1; IJ = 3w - 41; PR = 6v-12; IK = 5v
So, on equating them, we get
QR = IJ ⇒ w - 1 = 3w - 41
⇒ 3w - w = 41 - 1
⇒ 2w = 40
∴ w = 20
And
PR = IK ⇒ 6v-12 = 5v
⇒ 6v - 5v = 12
∴ v = 12
Thus, the value of v = 12 and w = 20.

(c) The net force acting on this object at t = 7 s is -13.2 N.
In the given question, the velocity graph of a 2.2 kg object as it moves along the x-axis.
The given mass = 2.2
a) We have to find the net force acting on this object at t = 1 s.
At t=1 s
Slope of a graph = acceleration
Acceleration = slope
Acceleration = 12/3
Acceleration = 4 m/s^2
Net force, F = m*a
F = 22*4
F = 88 N
So the net force is 88 N.
b) We have to find the net force acting on this object at t = 4 s.
At t = 4 s
Acceleration, a=slope of graph
a = ( 12 - 12) /(3 - 0)
a = 0 m/s^2
The net force , F = m * a
F = 2.2 * 0 = 0 N
c) We have to find the net force acting on this object at t = 7 s.
At t = 7 s
Acceleration, a = ( 0 - 12 ) / (8 - 6)
a = - 6 m/s^2
The net force, F = m * a
F = 2.2 * (-6)
F = -13.2 N

x = 3
yes, that's really it.
it just means that any value is valid for y.
this line is not a function, because the one valid value for x (3) has infinitely many assigned y values.
10.
the usual equation for a line is
y = ax + b
with "a" being the slope, "b" being the y-intercept (the y-value when x = 0).
we see that b = 0, as the line goes through the origin (0, 0).
the slope is the ratio
y coordinate difference / x coordinate difference
when going from one point on the line to another.
we see e.g. the points (0, 0) and (1, -3). I always recommend to look for points with integer coordinates.
when going from one to the other,
x changes by +1 (from 0 to 1).
y changes by -3 (from 0 to -3).
the slope "a" = -3/1 = -3.
the line equation is
y = -3x
the car is traveling along the road with a speed of v=(2s) m/s, where s is in meters.

In the given question, a car is travelling along the road with a speed of 2s m/s, where s is in meters.
We have to determine the tangential and normal components of the acceleration when s = 10 m.
Speed (v) = 2s
Motion is circular so, Radius of circle = 50m
Tangential acceleration = dv/dt
Tangential acceleration = d(2s) / dt
Tangential acceleration = 2(ds)/dt
Tangential acceleration = 2v
Tangential acceleration = 2(2s)
Tangential Acceleration = 4s
As given s = 10 m
Tangential acceleration = 4 x 10
Tangential acceleration = 40 m/s^2
Normal acceleration = v^2/ r
Normal acceleration = 4s^2/r
Normal acceleration = {4 x 10^2}/50
Normal acceleration = {4 x 100}/50
Normal acceleration = 400/50

$64 jacket; 20% discount
Answer:
$51.20 is the cost after a 20% reduction.
Explanation:
There are two ways that this can be determined.
First, we can find what 20% of the original $64 price is and subtract the discount from the price.
20% = 0.20
0.20 ( $64) = $12.80
$64 - $12.80 = $51.20
Or
We can say that $64 is 100% of the price and subtract the 20% meaning the sale price will be 80% of the original price.
100% = 1.00 20% = .20
$64(1.00-.20) = $64(.80) = $51.20

four mutually exclusive events a;b;c;d each have a probability of 0:25. what is the probability that two or more of them will occur?
The probability that two or more of the events will occur is 0.683594.
The probability that two or more of the events will occur is equal to 1 minus the probability that none of the events will occur. Since the probability of each event occurring is 0.25, the probability that none of the events will occur is (1 - 0.25) * (1 - 0.25) * (1 - 0.25) * (1 - 0.25) = 0.316406. Therefore, the probability that two or more of the events will occur is 1 - 0.316406 = 0.683594.
Alternatively, you can find the probability that two or more of the events will occur by adding up the probabilities of each of the ways that two or more of the events can occur.
There are four ways that two events can occur (for example, event A and event B), six ways that three events can occur (for example, event A, event B, and event C), and four ways that all four events can occur.
Thus, the probability that two or more of the events will occur is (4 * 0.25 * 0.25) + (6 * 0.25 * 0.25 * 0.25) + (4 * 0.25 * 0.25 * 0.25 * 0.25) = 0.683594, which is the same result as before.
