  x - 3y = 1   ⇒ 3x - 9y = 3
3x - 5y = 11 ⇒ 3x + 5y = 11
                             -14y = -8
                              -14    -14
                                   y = ⁴/₇
                            x - 3y = 1
                           ⁴/₇ - 3y = 1
                         - ⁴/₇        - ⁴/₇
                                -3y = ³/₇
                                 -3     -3
                                   y = ⁻¹/₇
                             (x, y) = (⁴/₇, ⁻¹/₇)

!!!PLEASE HELP ASAP!!! <br> I WILL GIVE MORR POINTS IF NEEDED AND MARK BRAINLIEST
Firlakuza [10]
The first one shows 1 cm and 7 mm, we need to convert 7 mm to cm
1 cm + 7 mm
= 1 cm + \frac{7}{10} cm
= 1 cm + 0.7 cm
= 1.7 cm
The first one is 1.7 cm

The second one shows 11 inches and 5/16 inches. Between number 11 and 12, there are 16 strips and the pointer lies on fifth strip, thus it show 5/16 inches. The second one is 11\frac{5}{16} inches.

The third one shows 13 cm and 8 mm. We need to convert mm into cm.
13 cm + 8 mm
= 13 cm + 0.8 cm
= 13.8 cm
The third one is 13.8 mm

The arrival of the city busses that trundle down my street is Poisson distributed. According to the published schedule, they arr
joja [24]

Answer:

There is a 3.33% probability that exactly two such busses arrive within 3 minutes of each other.

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

In which

x is the number of sucesses

e = 2.71828 is the Euler number

\mu is the mean in the given time interval.

What is the probability that exactly two such busses arrive within 3 minutes of each other

The mean is one bus each 10 minutes. So for 3 minutes, the mean is 3/10 = 0.3 buses. So we use \mu = 0.3

This probability is P(X = 2).

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

P(X = 2) = \frac{e^{-0.3}*(0.3)^{2}}{(2)!} = 0.0333

There is a 3.33% probability that exactly two such busses arrive within 3 minutes of each other.
