Given :
P( X = 70 ) = 0.62 .
P( X = 80 ) = 0.23 .
To Find :
We need to find If a person reaches their 70th birthday, what is the probability that they will live to age 80 .
Solution :
We need to find :
We know ,
So ,
Hence , this is the required solution .
First, let's declare a variable
x = # of students
Now, let's create an equation to model the problem.
x * 0.273 = 125
Divide both sides by 0.273
x = 457.8 = 458 students.
Note, I rounded to the nearest whole number.
The answer is Letter B - $2,850.
Multiply the number of shares to their respective costs per share. Add the results. Get the total number of shares then divide it by 10 before multiplying the result to 4.25. Add the product to the previous total.
Hyren Airlines: 92 shares x 13.70 = 1260.4
Giaco Household Goods: 130 x 3.28 = 426.40
Iwad Records: 126 x 8.06 = 1015.56
Total: 2,702.36
Commission: (92 + 130 + 126) 348 shares / 10 shares = 34.8 x 4.25 = 147.90
Total: 2702.36 + 147.90 = 2,850.26 or 2,850
You have a good day and good luck on that question
Answer:
Step-by-step explanation:
<u>Find the missing angle:</u>
- m∠L = 180° - 60° - 45° = 75°
<u>Use the law of sines to determine the lengths of the sides:</u>
- LM / sin ∠K = KM / sin 75°
- 12 / sin 60° = KM / sin 75
- KM = 12 sin 75° /sin 60° = 13.4 (rounded)
- KL / sin ∠M = LM / sin ∠K
- KL / sin 45° = 12 / sin 60°
- KL = 12 sin 45° / sin 60° = 9.8 (rounded)
<u>Find perimeter:</u>
- P = 12 + 13.4 + 9.8 = 35.2
