Answer:

Step-by-step explanation:

The probability distribution in the second row simply shows the probabilities for each number in the first row.

To find the probability that x is between -5 and 5, you can add the probabilities -5 < x < 5.

P(-5) = 0.15

P(0) = 0.05

P(5) = 0.1

0.15 + 0.05 + 0.1 = 0.3

Bad White [126]

I = PRT....and we are looking for T....so lets re-arrange this...
I / PR = T
I = 4485
R = 11.5% = 0.115
P = 6500

now we sub and solve
I / PR = T
4485 / (6500 * 0.115) = T
4485 / 747.5 = T
6 = T <=== so ur answer is 6 years

Step-by-step explanation:

Step 1: Identify

Angle θ = 35°

Opposite Leg BC = x

Adjacent Leg AC = 2

Step 2: Solve for x

Substitute [Tangent]: tan35° = x/2
Isolate x: 2tan35° = x
Rewrite: x = 2tan35°
Evaluate: x = 1.40042
Round: x ≈ 1.40

THEREFORE,(15+10+6)/30=31/30

2)1/3 ÷1/2+1/4

=1/3×2/1 +1/4 (D.M.A.S)

=2/3+1/4

=L.CM OF DINOMENATORS 12 AS L.C.M OF 3 AND 4.

(8+3)/12

=11/12
