solve for x 4(x-3)-8=16

Answer:

7 hours

Step-by-step explanation:

First find the total number of hours she practices based on the average of 2 hours a day for six days.

This means 6*2 = 12 , she practices a total of 12 hours.

Next find the total hours she already practiced. She practices 1 hour a day from Mon to Fri, which is 5 days, so 1*5 = 5 hours. This is the hours she practiced already.

To meet the mean, she needs to practice 12-5 = 7 hours more on Saturday.

Answer:

must practice 7 hours on Saturday

Step-by-step explanation:

Let 'x' = number of hours on Saturday

(5 (hours) + x) / 6 (days) = 2

[tex]\frac{5+x}{6}[/tex] = [tex]\frac{2}{1}[/tex]

Cross-multiply to get 5 + x = 12

Answer:

t=4

Step-by-step explanation:

4t-2=14

You then add 2 to both sides and get

4t=16

Then you must divide 16 by 4 and get

t=4

The solution of the linear equation 4t - 2 = 14 will be 4.

In other words, the collection of all feasible values for the parameters that satisfy the specified mathematical equation is the convenient storage of the bunch of equations.

The equation is given below.

4t - 2 = 14

The degree of the equation is one, so the equation will be a linear equation. Then solve the equation for 't', then we have

4t - 2 = 14

4t = 16

t = 16 / 4

t = 4

The solution of the linear equation 4t - 2 = 14 will be 4.

Step-by-step explanation:

Answer:

8 = f (13-2)

8=13f-2f

8=11f

8 / 11 = 11f / 11

8/11=f

f=8/11

Step-by-step explanation:

Answer:

Simplifying

8 = F + -1(13 + -2)

Combine like terms: 13 + -2 = 11

8 = F + -1(11)

Multiply -1 * 11

8 = F + -11

Reorder the terms:

8 = -11 + F

Solving

8 = -11 + F

Solving for variable 'F'.

Move all terms containing F to the left, all other terms to the right.

Add '-1F' to each side of the equation.

8 + -1F = -11 + F + -1F

Combine like terms: F + -1F = 0

8 + -1F = -11 + 0

8 + -1F = -11

Add '-8' to each side of the equation.

8 + -8 + -1F = -11 + -8

Combine like terms: 8 + -8 = 0

0 + -1F = -11 + -8

-1F = -11 + -8

Combine like terms: -11 + -8 = -19

-1F = -19

Divide each side by '-1'.

F = 19

Simplifying

F = 19

Because of some theory with angles on same sides of a line between parallel lines, take 180 and subtract the ones you have. 180-107=73 degrees= m angle B

180-46=134 degrees - m angle A

Answer: Mean = 7.8

              Median = 9

             Mode = 2,9

Step-by-step explanation: Mean is the average value of a data set. Mean from a frequency table is calculated as:

[tex]E(X)=\frac{2(10)+3(9)+9(10)+11(7)+12(3)+15(4)+16(3)}{10+9+10+7+3+4+3}[/tex]

E(X) = 7.8

Mean for the given frequency distribtuion is 7.8.

Median is the central term of a set of numbers. Median in a frequency table is calculated as:

1) Find total number, n:

n = 10 + 9 + 10 + 7 + 3 + 4 + 3 = 46

2) Find position, using: [tex]\frac{n+1}{2}[/tex]

[tex]\frac{n+1}{2}=\frac{47}{2}[/tex] = 23.5

Median is in the 23.5th position.

3) Find the position by adding frequencies: for this frequency distribution, 23.5th position is 9

Median for this frequency distribution is 9.

Mode  is the number or value associated with the highest frequency.

In this frequency distribution, 2 and 9 points happen 10 times. So, mode is 2 and 9.

Mode for this distribution is 2 and 9.

Following are the calculation of mean, median, and modes:

Given value:

[tex]\bold{x \ \ \ \ \ \ f} \\\\ 2\ \ \ \ \ 10 \\3\ \ \ \ \ 9\\9 \ \ \ \ \ 10\\11\ \ \ \ \ 7\\12 \ \ \ \ \ 3\\15 \ \ \ \ \ 4\\16 \ \ \ \ \ 3\\[/tex]

To find:

mean, median, and modes=?

Solution:

[tex]\bold{x \ \ \ \ \ \ f \ \ \ \ \ \ cf \ \ \ \ \ \ fx} \\\\2\ \ \ \ \ 10 \ \ \ \ \ 10 \ \ \ \ \ 20 \\3\ \ \ \ \ 9 \ \ \ \ \ 19 \ \ \ \ \ 27 \\9 \ \ \ \ \ 10\ \ \ \ \ 29 \ \ \ \ \ 90 \\11\ \ \ \ \ 7\ \ \ \ \ 36 \ \ \ \ 77 \\12 \ \ \ \ \ 3\ \ \ \ \ 39 \ \ \ \ 36\\15 \ \ \ \ \ 4\ \ \ \ \ 43 \ \ \ \ 60\\16 \ \ \ \ \ 3\ \ \ \ \ 46 \ \ \ \ 48 \\[/tex]

[tex]\Sigma f = 46 \ \ \ \ \ \ \ \ \ \ \Sigma fx= 358[/tex]

Calculating the Mean:

[tex]Mean=\frac{\Sigma fx}{\Sigma f}[/tex]

          [tex]=\frac{358}{46}\\\\= 7.78[/tex]

Calculating the Median:

[tex]n= \Sigma f= 46[/tex]

[tex]Median=\frac{ (\frac{n}{2})^{th} +(\frac{n}{2} +1)^{th}}{ 2}[/tex]

             [tex]=\frac{ (\frac{46}{2})^{th} +(\frac{46}{2} +1)^{th}}{ 2}\\\\=\frac{ (23)^{th} +(24)^{th}}{ 2}\\\\=\frac{ 3 +3}{ 2}\\\\=\frac{ 6}{ 2}\\\\=3[/tex]

Calculating the Mode:

Mode is the value of 'x' with the highest frequency is 10 for x= 2 and x=9 therefore, the mode is "2,9".
