If 2/3p+6=7/6p what is the value of p?

ehidna [41]

The first thing to do is to clear the equation of fractions by multiplying by its LCM, which is 6 in this case. When you do that, you will get the equation
4p + 36 = 7p. Much easier to deal with, right? Now move the 4p over by subrtracting it: 36 = 3p, and p = 12

Consider the following population of N = 12 scores:

Goshia [24]

Answer:

Step-by-step explanation:

1. Find the minimun and maximun value of the data.

Minimun: 2

Maximun: 6

2. Calculate the range (R).

Range=

6 - 2=

3. Calculate the average.

Average= (Sum of all values) / N

Average= (2+3+3+3+4+4+4+4+5+5+5+6) / 12

Average= (48) / 12

Average= 4.

4. Calculate the M and round the value down.

$M=\sqrt{N} =\sqrt{12}=3.46$

$M= 3$

6. Calculate A.

$A=\frac{R}{M} =\frac{4}{3} =1.3333$

7. Craft your table.

(Check attatched image 1).

LL: Lower limit.

UL: Upper limit.

8. Calculate the limits and fill out the table.

LL / UL

2.00 2.00+A=3.33

3.33 3.3333 +A=4.66

4.66 5.99

5.99 7.32

7.32 8.65

Filled out table: check attatched image 2.

9. Check the data, count how many values fall into each interval and annotate on "frequency".

For example: There are 4 values between 2 and 3.33, these values are 2,3,3, and 3. Therefore, we write 4 on the frequency (absolute) cell for this row of the table. And we do the same for all the other classes.

Check attatched image 3.

10. Calculate the frequency (relative) for all classes.

For example: the first class (row 1 of the table) contains 4 values. Therefore, it's relative frequency would be:

$\frac{4}{N}=\frac{4}{12} =0.3333=$ 33.33%

Note: We divide by 12 because N=12.

Do the same for all the other rows and finish filling out the table.

Check attatched image 4.

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

Extra. To make an histogram, take the interval and the absolute frequency and graph it in the fashion shown in attatched image 5.

How to calculate area when you are given volume of 182m3 and height of 2.8m

Elza [17]

Hey there!

We simply have to do 182/2.8, and you will get the area (65m^2).

We know that the formula for area is length x width, and the formula for volume is length x width x height. In the volume formula, we can see it can also be area x height to get volume. So, we know that area x height = volume, right? And in this equation, we are given volume and height. If V = ha, with V = volume; h = height; a = area, we can divide "h" on both sides, and we get V/h = a, or volume divided by height is area. To solve for the above equation, we can plug the numbers in the formula: 182/2.8 = a, or 65 = a.

Hope this helps! Have an amazing day, and remember, you've got this!
