If 30 miles is ⅔s of Kevin's drive, then his drive would be a total of 45 miles.

explanation: if you divide 30 in half, you'd get 15 [which is ⅓ of Kevin's drive], and add another third [15 miles], you'd get 30+15, which equals 45.

what is the length of the longest side of a triangle that has the vertices (2, 6), (-4, 6), and (-4, 4)? a. 2/10 units b. 40 uni
rewona [7]
Length (2, 6) to (-4, 6) is sqrt((x2 - x1))^2 + (y2 - y1)^2) = sqrt((-4 -2)^2 + (6 - 6)^2) = sqrt((-6)^2 + 0) = 6

Length (2, 6) to (-4, 4) is sqrt((-4 - 2)^2 + (4 - 6)^2) = sqrt((-6)^2 + (-2)^2) = sqrt(36 + 4) = sqrt(40)  = 2sqrt(10) units

Length (-4, 6) to (-4, 4) is sqrt((-4 - (-4))^2 + (4 - 6)^2) = sqrt(0^2 + (-2)^2) = 2

Therefore, the length of the longest side is 2sqrt(10) units

Find the sum of square root 5 and 2 square root 16 in simplest form. Also, determine whether the result is rational or irrationa
a_sh-v [17]

Answer:

sqrt(5) + 8

The result is irrational because the sqrt(5) is a non-repeating, non terminating decimal that cannot be written as a fraction.

<em>Brainliest, please!</em>

Step-by-step explanation:

sqrt(5) + 2sqrt(16)

sqrt(5) + 2(4)

sqrt(5) + 8

Suppose a life insurance company sells a $240,000 one year term life insurance policy to a 25-year old female for $210. The prob
skelet666 [1.2K]

Answer:

$112.08 every year.

Step-by-step explanation:

Let's suppose a game in which we bet a certain amount of money ''A'' to a certain result and the probability of that result is ''p''. If the prize that we get is ''P'' therefore the expected value of gain is  :

E=p(P-A)+(1-p)(-A)=pP-A

Now,let's suppose that the female is ''betting on her death'' ⇒

P(she survives) = 0.999592

P(she doesn't survive) = 1 - 0.999592=4.08(10^{-4})

E(25-year old female) = 4.08(10^{-4}).(240000)-210=-112.08

The negative sign of E is important.It means that every year the 25-year old female will lose $112.08.

Therefore, the expected value of this policy to the insurance company is $112.08 every year.
