Answer:

0.81

Step-by-step explanation:

The letters between L and P are M,N,O.

It is inclusive, so we have 5 letters L,M,N,O,P.

The letters which we can choose we have 26-5=21.

The probability to choose a letter not between L and P is 21/26=0.81

The solution is 0.81, ie,

You have 81% chance to choose latter not between L and P.

Determine whether the following lines are parallel, perpendicular or neither
Ksenya-84 [330]

Answer:

Neither

Step-by-step explanation:

1.) has a vertical jump from (4,5) to (4,6), so it is not a linear line.

2.) has a vertical jump from (3,2) to (3,-8) and a horizontal segment from

     (3,2) to (9,2)

Therefore there is no correlation between the two lines at all.

)A spinner is divided into sections of equal size, of which some are red, some are blue, and the remaining are green. The probab
stiv31 [10]

Answer:

40%

Step-by-step explanation:

The probability of the arrow landing on the green section is a 40% chance

This is because there are only 3 sections where one is 50 and the other is 10

To find the green we can create an equation, where x = green section

50 + 10 + x = 100

The equation equals 100 because that's the highest the percentage will go in probability, unless we were told otherwise

60 + x = 100

x = 100 - 60

x = 40

Solve. 90^x = 27. Explain every step.
DaniilM [7]

Answer:

The answer is ⇒ x = 0.73244

Step-by-step explanation:

∵ 90^x = 27 ⇒ insert log in both sides

∴ log(90)^{x}=log(27)

∵ 90 = 9 × 10 , 27 = 3³

∵ log(a)^<em>b</em> = <em>b</em><em> </em>log(a)

∴ log(9 × 10)^x = x log(9 × 10)

∴ xlog(9*10)=log(3^{3})

∵ log(a × b) = log(a) + log(b)⇒log(9 × 10) = log(9) + log(10)

∴ x[log(9)+log(10)]=3log(3)

∵ log(10) = 1 , 9 = 3²

∴ x[log(3)^{2}+1]=3log(3)

∴ x[2log(3)+1] = 3log(3)

∴ x = (3log3)/[2log(3)+1]

∴ x = 0.73244
