Vertical, Complementary and Linear Pair Angles

dlinn [17]

1) Vertical angles-the angles will equal each other.
8+7x=9x-4
12+7x=9x
12=2x
x=6
2) Supplementary-Angles will add up to 180
6+13x+7x+14=180
20+20x=180
20x=160
x=8

Suppose Kaitlin places $ 4000 in an account that pays 18% interest compounded each year.

Ratling [72]

Answer:

a) $4720

b) $5569.60

Step-by-step explanation:

Initial amount = $4000

Interest rate = 18% PA compounded

<u>Amount after 1 year</u>

$4000*1.18 = $4720

<u>Amount after 2 years</u>

$4720*1.18 = $5569.60

The length of time for one individual to be served at a cafeteria is a random variable having an exponential distribution with a

umka2103 [35]

Answer:

0.01265

Step-by-step explanation:

Since, if the time to be served has an exponential distribution with a mean of 7, then

$P(T < t_0) = 1 - e^{-\frac{t_0}{7}}$

Chance to be served in under 2 minutes:

$P(T$

Let A represents the number of days when a person is served in less than 2 minutes,

Hence,

the probability that a person is served in less than 2 minutes on at least 5 of the next 7 days ( using binomial distribution )

= P(A=5) + P(A=6) + P(A=7)

$=^7C_5(0.249)^5(1-0.249)^2+^7C_6(0.249)^6(1-0.249)^1+^7C_7(0.249)^7(1-0.249)^0$

$=\frac{7!}{2!5!}(0.249)^5(1-0.249)^2+\frac{7!}{1!6!}(0.249)^6(1-0.249)^1+\frac{7!}{0!7!}(0.249)^7(1-0.249)^0$

≈ 0.01265
