hey mate:-

hey mate:- A{12,20,21,22,23}

here number of elements in A= 5

B{18,19,20,21,22}

here number of elements in B= 5

number of elements in A= number of elements in B= 5

as we know

when number of elements are same

given

here number of elements in A=here number of elements in B

there fore these are equivalent sets..,,

For the following pairs of assertions, indicate which do not comply with our rules for setting up hypotheses and why (the subscr

torisob [31]

Answer:

Options B, C, D & E do not comply with the rules for setting up hypotheses

Step-by-step explanation:

(A). H0: m = 100, Ha: m > 100.

These hypotheses fully complies with our rules.

B). H0: s = 20, Ha: s 20.

H0 is not an equality claim such as σ = 20. Hence, these hypotheses are not in compliance with our rules.

(C). H0: p -:: .25, Ha: p = .25

H0 should definitely contain the equality claim, although Ha contains it here. Thus, these are not legitimate and don't comply with our rules

(D)H0: m1 - m2 = 25, Ha: m1 - m2 > 100

The given value of 25 for m1 - m2 in H0 should also appear in Ha,but it does not do so here, so it doesn't comply with our rules.

E)H0: S2 = S2, H : S2 -:: S2

Each S2 is a statistic and so it does not belong in a hypothesis.

Find the perimeter of a rectangle of A=2.76x10^12cm^2 and one side is 4.6x10^5

levacccp [35]

Answer:

1.292 x 10^7 cm^2

Step-by-step explanation:

Since the area of a rectangle is A = L x W and you are given the area and one side, you can rearrange this equation to solve for the other:

$L=\frac{A}{W}\\L=\frac{2.76 \times 10^{12}}{4.6 \times 10^5}\\L = 6 \times 10^6$

Therefore the length of the other side is 6 x 10^6.

The perimeter of a rectangle is P = 2L + 2W. We can solve that now that we have the length of the sides:

$P = 2(6 \times 10^6) + 2(4.6 \times 10^5)\\P = 1.292 \times 10^7$
