40, because if you have 3 and 10 and 12 is 4 times 3. So you would multiply 10x4 to get 40.

Math queztion -8x + 40> -16 =
emmainna [20.7K]

Answer: x < 7

Step-by-step explanation: Just like any of your two-step equations, in this inequality, start by isolating the x term which in this case is -8x by subtracting 40 from both sides.

That leaves you with -8x > -56.

To get <em>x</em> by itself, divide both sides by -8 but watch out.

If you divide both sides of an inequality by a negative,

you must switch the direction of the inequality sign.

So we have x < 7.

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
