Answer:

∠MON = 130

Step-by-step explanation:

∠LON = 180°

∠LOM + ∠MON = 180 -------equation

where:

∠LOM = 4x + 30

∠MON = 8x + 90

plugin values into the equation

4x + 30 + 8x + 90 = 180

4x + 8x + 30 + 90 = 180

12x = 180 - 30 - 90

12x = 60

x = 60/12

x = 5

plugin values to ∠MON = 8x + 90

∠MON = 8x + 90

∠MON = 8(5) + 90

∠MON = 130

Answer:

LOM= 130º

Step-by-step explanation:

Combine the two equations and set it to equal 180º(LON), 180º=12x+120º

next subtract 120º from both sides, 60º=12x. Now divide both sides by 12, 5=x. Now you can plug 5 back into the original equation to calculate MON, 8x5+90º

Answer:

QR(3), RS(3), PQ(3), ST(11), RP(6), RT(14), SP(9), QT(17)

Step-by-step explanation:

The diagram is not shown, but we assume the points are in the sequence ...

P, Q, R, S, T

Since QR = RS, R is apparently the midpoint of QS, So ...

23. QR = 6/2 = 3

24. RS = QR = 3

25. PQ = QR = 3

26. ST = PT -PQ -QS = 20 -3 -6 = 11

27. RP = PQ +QR = 3 +3 = 6

28. RT = RS +ST = 3 +11 = 14

29. SP = PQ +QS = 3 +6 = 9

30. QT = QS +ST = 6 +11 = 17

From a sample with n=32, the mean duration of a geyser's eruption is 3.81 minutes and the standard deviation is 1.07 minutes. Us

Damm [24]

Notice that

$1.67=3.81-2\times1.07$
$5.95=3.81+2\times1.07$

This means you are looking for

$\mathbb P(1.67$

Chebyshev's theorem states that for any constant $k>0$ ,

$\mathbb P(|X-\mu|$

which means

$\mathbb P(1.67$

In other words, at least 75% of the geysers will have eruptions lasting between 1.67 and 5.95 minutes. Out of 32 geysers, then, one can expect at least 24 of them to have eruptions with between these durations.
