22. l = 12m

b = 10m

Perimeter = 2(l + b)

= 2(12 + 10)

= 24 + 20

= 44m

Area = l×b

= 12 × 10

= 120m²

(a) Fencing required = 44m

Cost per metre = $12

Cost for the fencing of 44m = 12 × 44

= $528

(b) Levelling required = 120m²

Cost per metre² = $50

Cost for the levelling of 120m² = 120 × 50

= $6000

Two regular polygons X and Y are such that the number of sides of X is
anyanavicka [17]

Based on the indices of the regular polygons, the number of sides that X has is 8. See the computation below.

<h3>What is the analysis for the above solution?</h3>

Assuming that X has G number of sides; and

Y has H number of sides, this means that:

G-H = 3 ...........1

Recall that the formula for the exterior angles is:

360/n; where n is number of sides

X = 360/G

Y = 360/H

(360/G) + (360/H) = 117°.......2


Solving 1 and 2 simultaneously, we obtain:

G= 8 and

H = 5

Thus, X has 8 sides.

Over the past 10 years, five mutual funds all had the same mean rate of return. The standard deviations for each of the five mut
tiny-mole [99]

Answer:

C. Vanity

Step-by-step explanation:

As each of the five mutual funds have same mean rate of return, we go for standard deviation of the rate of return to judge which one has the least consistency among the five.  

We know that standard deviation is a measure for variation in a data-set. So more the standard deviation of a data, more is the variation in the data-set and less is the consistency of the data-set.

Here, among the given five mutual fund, we see that "Vanity" has the highest standard deviation (9.4%) in rate of return.  So the mutual fund "Vanity" has the least consistency.
