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

What is the y-intercept on this table?

Answers

Answer:

the y intercept is 1 at the point (0,1)

Step-by-step explanation:

the y-intercept is when x = 0 because the x-axis is how many you go over, so if you go over none and up or down some, the point lies on the y-axis, and when a point lies on the y-axis, it's the y-intercept.

hope this helps :))

the y-intercept occurs where x=0, therefore the y-intercept is 1 :)

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

Write the function f(x) = 6x + 5 in terms of z by substituting z for x in the function

Answers

Answer:

f(x)=6x+5

You must do this step because the work is asking for it

z=6x+5

Than you change x and z to find z or the inverse of that function

x=6z+5

Subtract-5 both sides

x-5=6z

Divide both sides with 6

(x-5)/6=(6z)/6

Now you simplify

z=(x-5)/6

Done ✅

Step-by-step explanation:

Answer:

f(x) = 6x + 5. To write f(x) in terms of z, substitute the value of x with z:

f(z) = 6z + 5.

The mean mass of 11 players in football team is 65.2kg .The mean mass of the team plus a substitute is 65.4kg what is the mass of the substitute

Answers

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

Given the following probability distributions:
Distribution C X P{X = Xi)
0 1 2 3 4
0 0.20 0.20 0.20 0.20
Distribution D X P{X = Xi)
0 1 2 3 4
0 0.10 0.40 0.20 0.10
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.
