Jenny has the correct solution for the group assignment. It is evident in her response because she uses the correct percentage of 41/100. Unlike Jeremy who uses 41/99. When using fractions or decimals the numerical range always extends to 100.

The decimal number would be 0.41.

There are 20 numbers in the set.

Given,

Set of numbers is 120

one number is increased by 300

and, mean increases to 135.

To find the how many numbers are in the set?

Now, According to the question:

Let the number of numbers be 'n'

Then, (sum of numbers)/n = 120

or, old sum = 120n

if one number is increased by 300, the new sum = (old sum + 300)

Then, (new sum)/ n= 135

or new sum = 135n = old sum + 300 = 120n + 300

The equation will be:

135n = 120n + 300

15n = 300

n = 20

Hence, There are 20 numbers in the set.

In the question:

The mean of a set of numbers is 120. if one number is increased by 300, the mean increases to 135.

If you have x, and your equation is 5/8x + 1/5x=99, what is x

noname [10]

$\frac{5}{8x} + \frac{1}{5x} = 99 \\ \\ \frac{33}{40x} = 99 \\ \\ 40x = 33 \times 99 \\ \\ x = 81.675$

LekaFEV [45]

I think I know how to do it

Your equation is:

P₁V₁ = P₂V₂

You Know:

Initial:

P₁ = 84 Pa

V₁ = 336 L

New:

P₂ = ?

V₂ = 216L

Plug this into the equation:

P₁V₁ = P₂V₂

(84 Pa)(336 L) = P₂(216 L) Divide 216 on both sides

$\frac{(84Pa)(336L)}{216L}=\frac{(P_{2})(216L)}{216L}$

130.6666666 = P₂

(if your doing significant figures, you have 2 sig figs)

130 Pa = P₂
