Gekata [30.6K]

Answer:

The profit of the company will be $224.85

Step-by-step explanation:

Let the equation of profit be termed as E(x)

we are given

amount of purchasing the policy (let a)= $1000

probability that women will live for at least 1 year (let b) = 0.9581

amount lost by insurance company if the women dies (let c) = 18,500-1000 = 17,500

the probability woman dies within one year (let d) = 1-0.9581=0.0419

the equation will be

E(x) of profit= a*b - c*d = 1000*0.9581 - 17500*0.0419

= 958.1 - 733.25

= 224.85

In a small town, there are 4 times as many left-handed males as there are left-handed females, and there are 3 times as many rig

horrorfan [7]

Answer:

(b) 24

Step-by-step explanation:

The given variable definitions and the given relationships let us write these statements:

LH males = 4 × LH females = 4x

RH females = 3 × RH males = 3y

LH males + RH males = 204 = 4x +y

RH females + LH females = 348 = 3y +x

Your favorite method of solving equations of this sort can tell you ...

(x, y) = (24, 108)

There are 24 left-handed females.

<em>Additional comment</em>

Other numbers involved here are ...

y = 108 . . . . right-handed males

204-108 = 96 . . . . left-handed males (=4×24)

348-24 = 324 . . . . right-handed females (=3×108)

If you want to solve the equations by hand, you can use substitution for y to get an equation in x:

3(204 -4x) +x = 348 ⇒ -11x = -264 ⇒ x = 24

A parallelogram with sides of 6 and 10 has an area of 30. Find the measure of the small angle of the parallelogram.

sergeinik [125]

Parallelogram area = base * height
30 = 10 * height
height = 3
Sine Parallelogram Angle = height / side
Sine (Angle) = 3 / 6
Sine Angle = .5
Angle = 30 degrees
