Answer:

24 slabs are required to pave in a rectangular courtyard

Step-by-step explanation:

Area of courtyard (rectangle):

A = lw

A = lb

Where,

l is length

b is breadth

A = 24 × 16

A = 384 m²

Area of each slab (square):

A = s²

A = (40)²

A = 1,600 cm²

A = 16 m²

NOTICE: Make sure to equalize the unit of measurement. 1 m = 100 cm

Now,

384 ÷ 16 = 24 slabs

Dave has 10 poker chips, 6 of which are red and the other 4 of which are white. Dave likes to stack his chips and flip them over
Marina86 [1]

The number of 10 chips stacks that Dave can make if two stacks are not considered distinct is 110.

The solution

To get the symmetric stacks, one has to subtract the symmetric stacks to know the ones that are asymmetric.

The symmetric are flipped. Given that they are double counted what we have to do is to divide through by 2.

6/2 = 3

10/2 = 5

4/2 = 2

1/2(10C6) - (5C3) + (5C3)

0.5(210-10+10)

= 110

You conduct a statistical test of hypotheses and find that the null hypothesis is statistically significant at level α = 0.05. Y
viktelen [127]

Answer:

Neither options one or two is true

Step-by-step explanation:

When we test a statistical hypothesis, we must specify a level of significance. It is this level of significance that presents the maximum probability at which we are willing to risk committing a type one error.

Therefore, it is independent of any other level of significance used.

Hence, we conclude that neither options one or two is true.

My square orchid garden abuts my house so that the house itself forms the northern boundary. The fencing for the southern bounda
lilavasa [31]

Answer:

The total cost of the fencing as a function of side is C = 8\cdot x.

Step-by-step explanation:

Dimensionally speaking, the total cost is equal to the product of length and cost per length. Given that orchid garden has a square form, there is only an input: Side (x), measured in feet. Therefore, the total cost of fencing is represented by the following formula:

C = (c_{west} + c_{south} + c_{east})\cdot x

Given that c_{west} = c_{east} = 2\,\frac{\$}{ft} and c_{south} = \$\,4\,\frac{\$}{ft}, the total cost of the fencing as a function of side is:

C = 8\cdot x
