Answer: the y intercept is -5

You can use the slope intercept form to find the answer. Aka y = mx + b

In this equation m is equal to the slope and b is equal to the y-intercept.

We already know the slope, 4. And we have two different point we can choose from. I’ll show how to solve with the first (1,-1) point.

Consider a machine that fills 275 gallon tanks of water. The owner discovers that the machine does not always dispense exactly 2

fenix001 [56]

Answer:

(a) The random variable X is a continuous random variable.

(b) The probability density function is shown below.

(c) The probability that a 275 gallon tank gets less than 272.5 gallons or more than 273.8 gallons of water is 0.285.

Step-by-step explanation:

Let the random variable X be denoted as the amount of water filled by the machine in a 275 gallon tank.

(a)

The random variable X is a continuous random variable.

A continuous random variables assumes infinite values. That is, they assume values in a fixed interval. For example, the distance covered by a car.

A discrete random variable assumes fixed definite values. They assume whole number values. For example, number of customers visiting a bank in an hour.

The amount of water in the tank can be any value between 0 to 275 gallon.

Hence, the random variable X is a continuous random variable.

(b)

The probability density function of the continuous random variable X is given as follows:

$0.25;\ 272$

$f_{X}(x) =0.20;\ 273$

$0.55;\ 274$

(c)

Compute the value of P (272.5 < X < 273.8) as follows:

$P(272.5$

Thus, the probability that a 275 gallon tank gets less than 272.5 gallons or more than 273.8 gallons of water is 0.285.

Write equibalent fraction for 2/3 and 3/4 using 12 as the common denominator

iogann1982 [59]

Answer:

2/3 = 8/12

3/4 = 9/12

Step-by-step explanation:

whatever you do to the denominator, you have to do the the numerator.

2/3 - 3 times 4 equals 12 and 2 times 4 = 8. so 2/3 = 8/12

3/4 - 4 times 3 equals 12 and 3 times 3 equals 9. so 3/4 = 9/12

hope this helps!!!

stepladder [879]

Answer:

Step-by-step explanation:

N = 4a + 6b

Let a=2 and b=3

N = 4*2 + 6*3

Multiply
