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.

96 divided by 12 = 12 groups of 8


96 divided by 8 = 8 groups of 12


96 divided by 32 = 32 groups of 3


96 divided by 3 = 3 groups of 32


96 divided by 24 = 24 groups of 4


96 divided by 4 = 4 groups of 24

URGENT!!!Find the value of x.
Debora [2.8K]

a x=12

the sum of angles in a triangle is 180

53+39+4+7x=180

96+7x=180

7x=86

x=84/7

x=12

b. sum of angles in a triangle is 180

5x+(6x-5)+75=180

5x+6x-5+75=180

11x+70=180

11x=180-70

11x=110

x=110/11

x=10

that's how to solve it
