Which statistical measure is not strongly affected by a few outliers in the data?.

Answers

Answer:  Median

The median is not affected by large or small outliers.

The mean on the other hand is affected by outliers. The more distant the outlier, the more skewed the mean will be.

For example, home prices will have a larger than normal mean because of very rich mansions which are far above the average group. This is why the median home price is a more useful measure of center.

Starting at its rightmost position, it takes 2 seconds for the pendulum of a grandfather clock to swing a horizontal distance of 18 inches from right to left and 2 seconds for the pendulum to swing back from left to right. which of the following equations models d, the horizontal distance in inches of the pendulum from the center as a function of time, t, in seconds? assume that right of center is a positive distance and left of center is a negative distance. d = 9 cosine (startfraction pi over 4 endfraction t) d = 9 cosine (startfraction pi over 2 endfraction t) d = 18 cosine (startfraction pi over 4 endfraction t) d = 18 cosine (startfraction pi over 2 endfraction t)

Answers

The expression that models d, the horizontal distance in inches of the pendulum from the center as a function of time, t, in seconds is d=9cosine[(π/2)t] option second is correct.

What is the frequency?

It is defined as the number of waves that crosses a fixed point in one second, known as frequency. The unit of frequency is per second.

The pendulum takes 2 seconds to swing a horizontal distance of 18 inches from right to left.

For swing back from left to right, it takes again 2 seconds to cover a horizontal distance of 18 inches.

The total time to complete the one cycle = 4 seconds

Thus, the frequency is the reciprocal of the time

f = 1/4

The expression for the angular speed is:

w = 2πf

w = 2π(1/4)

w = π/2

The distance of the pendulum from the center A = half the horizontal                                  

                                                                                 distance of 18 inches

A = 18/2

A = 9 inches

We know the cosine function for the pendulum is given by:

d = Acosine(wt)

d = 9cosine(πt/2)  or

d = 9cosine[(π/2)t]

Thus, the expression that models d, the horizontal distance in inches of the pendulum from the center as a function of time, t, in seconds is d = 9cosine[(π/2)t]

A poll worker analyzing the ages of voters found that mu = 65 and sigma = 5. what is a possible voter age that would give her zx = 1.14? round your answer to the nearest whole number. 59 66 71 90

Answers

A poll worker analyzing the ages of voters found that μ = 65 and σ = 5. The possible voter age that would give her zx = 1.14 is 71.

What do you mean by standard deviation?

In statistics, Standard deviation is a measure of the variation of a set of values.

σ = standard deviation of a population

N = number of observations of population

X = mean

μ = population mean

It is given that the random variable,

X = The ages of voters

μ = The analysis is having mean of 65

Standard deviation = 5

X = normal (65,5) Now, we will convert it into Z-score concept ,

Z = x - 65/ 5

z = 1.14

X = 65 + 5z

So, X = 65 + 5(1.14)

         = 65 + 5.7

         = 70.70

Therefore, We can also write it by rounding off the value,i.e.=71

The possible voter age that would give her zx = 1.14 is 71.

It costs a zoo $3 to feed the kookaburras for 4 hours. Write an equation relating the total cost y to the number of hours x.

Answers

Answer:

y=0.75x

Step-by-step explanation:

$3 for every 4 hours

$0.75 for every hour

y=0.75x

The equation relating the total cost (y) to the number of hours (x) is y = 0.75x.

The equation that relates the total cost (y) to the number of hours (x) can be derived from the given information. We know that the cost is $3 for 4 hours of feeding kookaburras.

The cost is proportional to the number of hours, and we can represent this relationship using a linear equation:

Cost = Rate × Hours

In this case, the rate is the cost per hour, which is $3 / 4 hours = $0.75 per hour.

Therefore, the equation relating the total cost (y) to the number of hours (x) is:

y = 0.75x

Here, "y" represents the total cost, and "x" represents the number of hours. This equation reflects the linear relationship between the total cost and the number of hours of feeding kookaburras in the zoo.

The statement that is accurate for the right triangle shown below is C. sec(a) = 1.06

What is the accurate statement?

The accurate statement is the one that can help us arrive at the correct angle in the diagram. That is sec(a) = 1.06. The formula is given as follows:

(hypotenuse)/(adjacent)

In the question we have, the hypotenuse is 50 while the adjacent is 47. Note that the hypotenuse is the longest side of the triangle, and the adjacent is often represented by the base.

So, we have;

50/47 = 1.06

The sum of three numbers is 78. The third number is 7 more than the first. The second number is 3 times the third. What are the numbers?

Answers

Answer:

10+51+17=78

Step-by-step explanation:

Alright, so at first I just took a random number and kept on working it out until I got the exact answer as 78. Finally, i got the third number as 17. Now, i know the third number is 7 more than the first so I have to subtract 17 and 7, 17-7=10. So the first number is 10. Ok, now i know that the second number is 3 times the third number (17) so you should multiply, 17x3=51. 51 is the 2nd number.

1st number=10

2nd number=51

3rd number=17

Add them, 10+51+17=78.

Answer:

First number = 10Second number = 51Third number = 17

Step-by-step explanation:

In the question we are given ,

Sum of three numbers is 78

Third no. is 7 more than first

Second no. is 3 times third

So , we are assuming that ,

Let first no. be x

Third no. be x + 7 ( because in question it is given that third number is 7 more than the first number ) .

Second no. be 3 ( x + 7 ) ( because in the question it is given that second no. is three times the third )

We are finding the solution by adding all these term and equating it with 78 because sum of these three numbers is equal to 78 .

Here we go ,

[tex] \longrightarrow \: x + 3(x + 7) + x + 7 = 78[/tex]

Step 1 : Solving the bracket part :

[tex] \longrightarrow \: \blue{x }+ \blue{ 3x} + \red{21} + \blue{ x} + \red{7 }= 78[/tex]

Step 2 : Adding like terms :

[tex] \longrightarrow \:5x + 28 = 78[/tex]

Step 3 : Transposing 28 to right hand side :

[tex] \longrightarrow \:5x = \green{78} - \green{28}[/tex]

Step 4 : Subtracting 28 from 78 :

[tex] \longrightarrow \:5x = 50[/tex]

Step 5 : Transposing 5 to right hand side :

[tex] \longrightarrow \:x = \cancel \frac{50}{5} [/tex]

Step 6 ; Cancelling 50 with 5 :

[tex] \longrightarrow \: \purple{\boxed{x = 10}}[/tex]

Therefore value of ,

x [ first number ] = 10

3(x + 7 ) [ second number ] = 51

x + 7 [ third number ] = 17

Verification :

We are verifying our answer by adding the three numbers and it must be equal to 78 .

10 + 51 + 17 = 78

61 + 17 = 78

78 = 78

L.H.S = R.H.S

Hence , Verified.

Therefore , our answer is correct .

For what value of c does the following system not have a solution.

1/2x+1/5y=2
5x+2y=c

Answers

Answer:

The answer is 3. 1. There is '0' point of intersection, that means they do not intersect. This only possible when the lined are parallel to each other.

'c' can be any real number except 4 for which the considered system would have no solution.

When does a system of linear equation have no solution?

When both the lines(represented by both the equations) are parallel and not coincident, then that system of linear equations have no solutions as there is no common point on both line.

If they are coincident (lying over each other), then there will have infinite solution since in that case, they will have infinite points in common.

Thus, if two lines are not in any of above case, they intersect at single point and in that case, the considered system of equation has unique single solution.

How to get the slope intercept form of a straight line equation?

If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:

[tex]y = mx +c[/tex]

Parallel lines(non-coincident) have same slope but different y-intercept.

Converting these equations to slope-intercept form, we get:

For first line:

[tex]\dfrac{1}{2}x + \dfrac{1}{5}y = 2\\\\ \dfrac{1}{5}y = 2 - \dfrac{1}{2}x\\\\y = 10 - \dfrac{5}{2}x\\\\y = -\dfrac{5}{2}x + 2[/tex]

and

For second line:

[tex]5x + 2y = c\\\\y = \dfrac{1}{2}c - \dfrac{5}{2}x\\\\y = -\dfrac{5}{2}x + \dfrac{c}{2}[/tex]

For no-solution, we need both lines to stay parallel but not coincident so that there is no common point (solution of this system) between those two lines.

Thus, we get:

[tex]2 \neq \dfrac{c}{2}\\\\\text{Multiplying 2 on both the sides}\\\\c \neq 4[/tex]

Since 'y' assumes real numbers assumingly, so 'c' can be any real number except 4 for which the considered system would have no solution.

Below is image attached of those parallel lines when c = 10.

Thus,  'c' can be any real number except 4 for which the considered system would have no solution.
