I would start by dividing by all the multipliers of the parentheses.
$\frac{PV}{nt} = r_{1} +r_{2}$
Then, I would subtract the unwanted variable from the sum.
$\frac{PV}{nt} -r_{2} = r_{1}$

The difference between the numbers of group A and group B will be 3, 1, 1, 3 and -1, 3, 5, -5. Then there is no meaningful difference between the two groups.

<h3>What is subtraction?</h3>

It simply implies subtracting something from an entity, group, location, etc. Subtracting from a collection or a list of ways is known as subtraction.

A scientist wants to know if there is a meaningful difference between two groups of gels that grow bacteria. He randomly selects five gels from each group, and counts the number of bacteria spots on each gel:

Group A: 9, 12, 13, 14, 17

The difference between the numbers will be given below.

3, 1, 1, 3

Group B: 6, 5, 8, 13, 8

The difference between the numbers will be given below.

-1, 3, 5, -5

There is no meaningful difference between the two groups.

Tom is buying topsoil for the flower bed shown below. One bag of topsoil covers 151515 square meters. How many bags of topsoil d

exis [7]

Answer:

2 bags of topsoil.

Step-by-step explanation:

The attached figure shows a flower bed.

One bag of topsoil covers 15 square meters.

We need to find how many bags of topsoil does Tom need to cover his flower bed.

The area of the flower bed is :

$A=\dfrac{1}{2}\times 12\times 5\\\\=30\ m^2$

Let he has to cover x bags of topsoil. So,

x = Area of flower bed/Area of 1 bag of top soil

x = 30/15

x = 2

Hence, he will need 2 bags of topsoil to cover his flower bed.

Answer:

Step-by-step explanation:

The computation of the mean is shown below:

= Total sum ÷ number of observations

= (1 + 2 + 2 + 2 + 3 + 1 + 4 + 0 + 5 + 3 + 6 + 2) ÷ 12

= 31 ÷ 12

= 2.58

= 2.6

= 3
