Answer:
perimeter= 17/3
area= 12
Step-by-step explanation:
for perimeter:
basically you need to add all sides
so to make it easier yo can put the equation in this way
4/3 + 5/3 + 8/3 = (and that gives you) 17/3
given they have common denominator you just add the numbers
for area:
the equation of the area of a triangle is:
1/2 x base x height
you just need to replace to end up with
1/2 x 8/3 x 6 = 12
Answer: 10.7 years.
Step-by-step explanation:
7,300 * (1 + 0.015)^x = 8,560 <=>
7,300 * 1.015^x = 8,560 <=>
1.015^x = 8,560 / 7,300 <=>
1.015^x = 1.1726 <=>
x = 10.694
To the nearest tenth:
x = 10.7 years
Answer:
a) 2.5×2.5×2.5-1.4×1.4×1.4=12.881
b) (2.5)2+2.5×1.4+(1.4)2=31.5
Step-by-step explanation:
yuh multiple 2.5 three times and subtract 1.4 multiple three times. 2.5×2.5×2.5-1.4×1.4×1.4
15.625-2.744=12.881.
b) when opening bracket Yuh multiple the number in the bracket by the number outside the bracket. when bracket is open Yuh can now add, multiple to obtain your answer please
(2.5)2+2.5×1.4+(1.4)2
5+2.5×1.4+2.8
7.5×4.2=31.5

Answer:
the customer's expected value of the cellphone insurance policy is -$38.64. (Option C)
Step-by-step explanation:
Based on the data given, 585/5000 or 11.7% of the total number policies have claims. This means, 100% - 11.7% = 88.3% have not claimed their cellphone insurance.
- In the chart, we are focusing on the customer's end because the question is asking for the customer's expected value↓
- In the chart, if the customer has no claims, then he losses his $48. However, if he has claims, he gains $32 since $80 - 48 = $32. Also, based on the data given by the company, 88.30% have no claims and only 11.7% of the customers have claims.
- To get the expected value, we will multiply -48 and 88.3% as well as 32 and 11.7%. 48 is negative because it indicates a loss.
Therefore, your Answer is -38.64
