Answer:
Step-by-step explanation:
You would never buy a 10-pack, because two 5-packs cost less.
To buy 3 bars you need a single bar and a pair of single bars for £0.82 + £0.82+ £0.41 = £2.05
To buy 30 bars you need 3 pairs of 5-bar packs = 3×£5.75 = £17.25
To buy the remaining 5 bars you need one 5-bar pack = £3
cost = £2.05 + £17.25 + £3 = £22.30
Answer:
The distance between the points is approximately 6.4
Step-by-step explanation:
The given coordinates of the points are;
(2, -2), and (6, 3)
The distance between two points, 'A', and 'B', on the coordinate plane given their coordinates, (x₁, y₁), and (x₂, y₂) can be found using following formula;

Substituting the known 'x', and 'y', values for the coordinates of the points, we have;

Therefore, the distance between the points, (2, -2), and (6, 3) = √(41) ≈ 6.4.
Solution: For a positively skewed distribution with a mean of m=20, the most probable value for the median is less than 20.
<u>Explanation:</u>
We know that in a symmetric distribution, the relationship between mean, median and mode is:

In case of negatively skewed distribution, the relationship between mean,median and mode is:

In case of positively skewed distribution, the relationship between mean,median and mode is:

Therefore, for a positively skewed distribution with a mean of m = 20, the median would be less than Mean. Hence the probable value of median is less than 20
Answer:
700 beads are in each bag.
Step-by-step explanation:
Just make the height the subject of the equation, by dividing the volume by everything else.
V / ((1/3) * <span>π</span> * r²) = h
