let 'm' be mid value of class and 'L' be upper limit in frequency table. The lower limit of class is ? Please prove and answer ​

Answers

Answer 1

Answer:

Lower Limit = 2m-L

Step-by-step explanation:

Given that,

The mid value of class = m

Upper limit in the frequency table = L

We need to find the lower limit of the class.

The mid value of a class is given by :

[tex]\text{mid-value}=\dfrac{\text{lower limit + upper limit}}{2}\\\\m=\dfrac{L+\text{lower limit}}{2}\\\\2m=L+\text{lower limit}\\\\\text{lower limit}=2m-L[/tex]

Hence, the lower limit of the class is 2m-L.

vector u = <2,5> . Describe how you would use a graphical method to add vector u to vector v (shown in the graph). Then, write the resultant vector in the component form.

Answers

Answer:

Step-by-step explanation:

Draw vector u in standard position. To add u to v, shift u three units to the right and one unit up so its initial point coincides with the terminal point of v. Use a dotted line to depict the shifted vector u. Finally, draw the resulting vector with its initial point at the origin and endpoint at v + u. The component form of this resulting vector is <5, -4>.

Answer:

3 trays of corn muffins and 2 trays of bran muffins

Step-by-step explanation:

c = 4m + 3w

b = 2m + 3w

16m and 15w

1 tray of corn muffins and 4 trays of bran muffins = $11

16 - 4 = 12

15 - 3 = 12

12 - 8 = 4

12 - 12 = 0

b = $2

c = $3

c = 3 x 1 = 3

b = 2 x 4 = 8

3 + 8 = 11

-----------------------------------------------------------------------------------------------------------------

2 trays of corn muffins and 3 trays of bran muffins = $12

c = 4m + 3w

b = 2m + 3w

16 - 8 = 8

15 - 6 = 9

8 - 6 = 2

9 - 9 = 0

b = $2

c = $3

c = 3 x 2 = 6

b = 2 x 3 = 6

6 + 6 = 12

-----------------------------------------------------------------------------------------------------------------

3 trays of corn muffins and 2 trays of bran muffins = $13

c = 4m + 3w

b = 2m + 3w

16 - 12 = 4

15 - 9 = 6

4 - 4 = 0

6 - 6 = 0

c = 3 x 3 = 9

b = 2 x 2 = 4

9 + 4 = 13

-----------------------------------------------------------------------------------------------------------------

4 trays of corn muffins and 0 trays of barn muffins = $12

c = 4m + 3w

b = 2m + 3w

16 - 16 = 0

15 - 12 = 3

c = 3 x 4 = 12

b = 2 x 0 = 0

12 + 0 = 12

Find the equation of the line.
Use exact
numbers.
Y= ( ) x+( )

Answers

Answer:

y=3x+3

Step-by-step explanation:

to find the y-int, you need to find the point the is on the y-axis (0,x). Or, 3 in this situation

for slope, you just need to do rise over run, or up and down first then, left and right. If i do that for this equation, I will get 3/1 which is the slope.

The equation would be y=3x+3

Work out the equation of the straight line which has a gradient of 2

Answers

Note: It seems you may forget to write the complete statement. Maybe you should have either mentioned the y-intercept or any other point to work out the equation.

Anyways I am assuming your complete statement is ''Work out the equation of the straight line which has a gradient of 2 and passes through (1, 4)''.

Answer:

We conclude that the equation of a line using the slope-intercept form is

[tex]y=2x+2[/tex]

Step-by-step explanation:

I am assuming your complete statement is ''Work out the equation of the straight line which has a gradient of 2 and passes through (1, 4)''.

The slope-intercept form of the equation

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

Here

m is the slopec is the y-intercept

Substituting the point (1, 4) and m=2 to determine the y-intercept

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

[tex]4 =2(1)+c[/tex]

[tex]4 = 2+c[/tex]

[tex]c = 4-2[/tex]

[tex]c = 2[/tex]

Thus, the equation of a line using the slope-intercept form is

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

m=2c=2

[tex]y=2x+2[/tex]

Therefore, we conclude that the equation of a line using the slope-intercept form is

[tex]y=2x+2[/tex]

Answer:

The marked angle GEF is 25

Step-by-step explanation:

Here, we want to calculate the value of the marked angle

Mathematically, a diagram should do justice to this

Please check the attachment for the diagram

The theorem we want to use is that the sum of opposite interior angles equals the exterior angle

Thus, mathematically;

2x + 1 + x + 19 = 6x + 2

3x + 20 = 6x + 2

6x-3x = 20-2

3x = 18

x = 18/3

x = 6

The angle marked GEF is x + 19

That will be 6 + 19 = 25
