2) Major league baseball salaries averaged $3.26 million with a standard deviation of $1.2 million in a certain year in the past. Suppose a sample of 100 major league players was taken. What was the standard error for the sample mean salary

Answers

Answer 1

Answer:

Standard error for the sample = $0.12 million

Step-by-step explanation:

Given:

Mean = $3.26 million

Standard deviation = $1.2 million

Number of sample = 100

Find:

Standard error for the sample

Computation:

Standard error for the sample = Standard deviation / √Number of sample

Standard error for the sample = 1.2 / √100

Standard error for the sample = $0.12 million

if x -12x + 36= 0 what is the value of x

Answers

the value of x is 36/11
To solve for x, we must get all the variables that contain the x value on one side:

X-12x+36=0
x - 12x = -36

Next, factor out an x:

x(1-12) = -36

x = 36/11

Distribution D X P{X = Xi)
0 1 2 3 4

A. Compute the expected value for each distribution.
B. Compute the standard deviation for each distribution.
C. Compare the results of distributions C and D.

Answers

Answer:

Step-by-step explanation:

The expected value of this distribution will be the Mean

upon calculation

For the distribution of C

1)   P(x=xi)  0    1          2        3       4

              0    0.20   0.20  0.20  0.20

[tex]Mean = Pi*xi[/tex]

           = 0*0+1*0.2+2*0.2+3*0.2+4*0.2

Mean    = 2

2) Standard deviation of C

        [tex]\sqrt{(xi-mean)^2 *P(xi)}[/tex]

        = 1.09

For the distribution of D

1)       P(x=xi)    0    1       2      3      4

                     0    0.1   0.4   0.2  0.1

[tex]Mean = Pi*xi[/tex]

          = 1.9

2) Standard deviation

       = 0.984

Upon comparing the result we observe that

C has greater expected value than D

C has greater standard deviation than D which means it is more spreading of the given data than D.

I need the value of x

Answers

Answer:

9.9

Step-by-step explanation:

Optional (extra) info to understand length of other leg:

This triangle is an iscoceles, how can I (or we) tell?? Well, the angles of a triangle always add up to 180° and we know the angles of 2 corners, 90° and 45° so we can do this to find the last angle where "c" is the unknown corner:

180 - (90 + 45) = c

180 - 135 = c

45 = c

so "c" is also equal to 45° so we can decisively conclude that this figure is an iscoceles triangle.

How to find x:

Use the pythagorean theorem

c = √a² + b²

Then calculate using that equation

c = √7² + 7²

c = 9.9

In this case "c" is for the length of hypotenus but the image asks for x so

x = c

and

c = 9.9

so

x = 9.9

A company has 2725 employees. Each employee is to be given an ID number that consists of one letter followed by 1 digits. How many different ID numbers are possible

Answers

Answer: There are 260 different ID numbers are possible.

Step-by-step explanation:

Given: Each employee is to be given an ID number that consists 1 letter followed by 1 digit .

Number of choices for each letter = 26 [English alphabet consists 26 letters]

Number of choices for each digit = 10

By Fundamental counting principle,

The number of different ID numbers possible = (Number of choices for each letter) x (Number of choices for each digit)

=26 x 10= 260

Hence, there are 260 different ID numbers are possible.

10n + 10(7n + 10) = -10(11 - n)

Answers

Answer:

n = -3

Step-by-step explanation:

P E M D A S

10 x 7n = 70n

10 x 10 = 100

10n + 70n + 100 = -10(11 - n )

80n + 100 = -10(11 - n )

80n + 100 = 10n - 110

80n + 100 - 100 = 10n - 110 - 100

80n = 10n - 210

80n - 10n - 10n - 210 - 10n

70n = -210

70n ÷ 70 = -210 ÷ 70

n = -3

How many apartment buildings were in the sample

Answers

Answer:

The number of apartment buildings in the sample was 9.

Step-by-step explanation:

The ANOVA table is as follows:

ANOVA

                     df        SS          MS         F        Significance F

Regression    1     41587.1      __        ___           ____

Total              8    51984.8     __        ___           ____

The degrees of freedom of Total is, n - 1.

Compute the sample size as follows:

DF of total = n - 1

              8 = n - 1

              n = 9

Thus, the number of apartment buildings in the sample was 9.

Answers

Answer:

80 ft/min

Step-by-step explanation:

Let h represent the height of the person shadow, x represent the distance between the person and the lamppost, y represent the length of the man shadow.

Therefore:

[tex]\frac{h}{x+y} =\frac{6}{y} \\\\substituting\ x=10,y=20:\\\\\frac{h}{10+20} =\frac{6}{20}\\\\\frac{h}{30} =\frac{6}{20}\\\\h=30*6/20\\\\h=9\ feet\\\\Therefore:\\\frac{h}{x+y} =\frac{6}{y}\\\\\frac{9}{x+y} =\frac{6}{y}\\\\9y=6x+6y\\\\9y-6y=6x\\\\3y=6x\\\\y=2x\\\\The\ person\ is\ walking\ from\ the\ lamppost\ at\ 40ft/min(\frac{dx}{dt}=40\ ft/min) \\\\y=2x\\\\Differentiating\ with\ respect\ to\ t:\\\\\frac{dy}{dt} =\frac{d}{dt}(2x)\\\\\frac{dy}{dt} =2\frac{dx}{dt}\\\\[/tex]

[tex]\frac{dy}{dt} =2(40\ ft/min)\\\\\frac{dy}{dt}=80\ ft/min[/tex]

The rate at which the length of the shadow is increasing when he is 30 feet away from the lamp post is  80 [tex]\frac{ft}{min}[/tex].

The height of the person shadow is to be = h

Given ,

The distance between the person and the man = x = 10

The length of the man shadow is = y = 20

By the similar triangle property corresponding sides of similar triangles are in the same ratio.

[tex]\frac{h}{x+y} = \frac{6}{y}[/tex]

[tex]\frac{h}{10+20} = \frac{6}{20}[/tex]

20h = 60 + 120

20h = 180

h = [tex]\frac{180}{20}[/tex]

h = 9feet

Therefore,

[tex]\frac{h}{x+y} = \frac{6}{y} \\\frac{9}{x+y} = \frac{6}{y} \\[/tex]

9y= 6x + 6y

9y-6y = 6x

6x = 3y

y = [tex]\frac{6}{3}x[/tex]

y = 2x

Differentiating both the sides with respect t,

[tex]\frac{dy}{dt} = 2\frac{dx}{dt}[/tex]

we know that ;

[tex]\frac{dx}{dt} = 40 \frac{ft}{sec}[/tex]

Therefore, by substitute the value

[tex]\frac{dy}{dt} = 2 . 40\frac{ft}{min}[/tex]

[tex]\frac{dy}{dt}[/tex] = 80[tex]\frac{ft}{min}[/tex].

The rate at which the length of the shadow is increasing is 80[tex]\frac{ft}{min}[/tex]  .

Answers

Answer:

Following are the solution to the given point:

Step-by-step explanation:

Let the box length l and the square base side be x, then

[tex]\to l+4x= 96 \\\\\to l=96-4x[/tex]

Calculating the volume of the box is:

[tex]\to V (x) = x^2 \\\\ \to l = x^2(96-4x)[/tex]

To find the critical value in this way, distinguish V with x and equal to zero

[tex]\to V'(x)=0 \\\\\to 4 \frac{d}{dx}(24x^2 - x^3)=0\\\\\to 4 (48x- 3x^2)=0\\\\\to 12x(16-x) = 0\\\\\to x= 12... [x \neq 0][/tex] (because the box will not exists)

Answer:   XY = 8

========================================================

Explanation:

Highlight XY in the sequence XYZ. We've highlighted the first two letters.

This means that we'll need to highlight the first two letters of MNL to get MN.

XY pairs with its corresponding part MN.

Due to the congruent triangles, we know that XY = MN.

The diagram shows MN = 8. Due to substitution or the transitive property (they're similar ideas) we know that XY = 8 as well.

As you can see, the order of the letters is important so we can properly align the letters.

so you would start of by doing 65.2(11) to find out what their actual mass is. 65.2x11= 717.2kg
then we would do the same for the team plus the substitute, so 65.4x11= 719.4
so 719.4-717.2= 2.2kg
