Equation A: y = 6x - 1

Greeley [361]

Answer:

comparing both the equation,

3X-3=6x-1

or, -2 =3X

or, X= -2/3

Y=6X-1

or, Y= 6× -2/3 -1

or, Y= -4-1

or, Y= -5

hence the required solution is (-2/3, -5)

Sara owns 3/4 of an acre of land. She wants to sell 5/6 of it. What fraction of an acre does she want to sell?

astraxan [27]

Answer:

5/8

Step-by-step explanation:

Sara owns 3/4 of an acre of land. She wants to sell 5/6 of it. What fraction of an acre does she want to sell?

The fraction of the acre of land that Sara wants to sell is calculated as:

= 5/6 of 3/4 of an acre of land

= 5/6 × 3/4

= 5/8 of an acre of land

Therefore, the fraction of an acre that she wants to sell = 5/8

The base of a triangle exceeds the height by 6 cm if the area is 260 cm² find the length of the base and the height of the trian

N76 [4]

$Let \: the \: base \: be \: x, \: the \: height \: would \: be: \:x-6\\The \: area \: is: \:$

$\frac{x(x - 6)}{2} = 260 \\ {x}^{2} - 6x = 520 \\ {x}^{2} - 6x - 520 = 0 \\ (x + 20)(x - 26) = 0 \\x = 26$

During the dry month of August, one U.S. city has measurable rain on average only 4 days per month. Assume all months have 30 da

Doss [256]

Answer:

The average number of days that will pass between measurable rain is 7.5.

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.

The expected period between the event happening is $\frac{1}{\mu}$

During the dry month of August, one U.S. city has measurable rain on average only 4 days per month. Assume all months have 30 days.

This means that

$\mu = \frac{4}{30}$

(a) If the arrival of rainy days is Poisson distributed in this city during the month of August, what is the average number of days that will pass between measurable rain? *

$\frac{1}{\frac{4}{30}} = \frac{30}{4} = 7.5$

The average number of days that will pass between measurable rain is 7.5.
