Answer:
Probability plays an important role in analyzing insurance policies to determine which plans are best for you or your family and what deductible amounts you need. For example, when choosing a car insurance policy, you use probability to determine how likely it is that you'll need to file a claim.

Answer:
(-6,4)
Step-by-step explanation:
Solve the following system:
{4 y + 5 x = -14 | (equation 1)
2 y + x = 2 | (equation 2)
Subtract 1/5 × (equation 1) from equation 2:
{5 x + 4 y = -14 | (equation 1)
0 x+(6 y)/5 = 24/5 | (equation 2)
Multiply equation 2 by 5/6:
{5 x + 4 y = -14 | (equation 1)
0 x+y = 4 | (equation 2)
Subtract 4 × (equation 2) from equation 1:
{5 x+0 y = -30 | (equation 1)
0 x+y = 4 | (equation 2)
Divide equation 1 by 5:
{x+0 y = -6 | (equation 1)
0 x+y = 4 | (equation 2)
Collect results:
Answer: {x = -6
, y = 4

Answer:
Step-by-step explanation:
take angle A as reference angle
using cos rule
cos A = adjacent/hypotenuse
cos A =10/15
cos A =0.66
A=48.194
A=48.2
angle A + angle B + angle C =180 degree (being sum of interior angles of a triangle)
48.2 + angle B + 90 =180
138.2 + angle B =180
angle B =180-138.7
angle B =41.8
for BC
using pythagoras theorem
a^2 + b^2 = c^2
AC^2 + BC^2 = AB^2
10^2 + BC^2 = 15^2
100 + BC^2 = 225
BC^2 = 225-100
BC^2 = 125
BC=5
BC=11.2
