Y= 9.2

Explanation:
13(y+7)=3(y-1)

Distribute the 13 on the left side and the 3 on the right side.

13y+91=3y-1

Subtract the 3y to the 13y (little brother goes to the big brother always)

10y+91=-1

Subtract 91 to the right side.

10y=92

Divide by 10.

Y=9.2

The waiting time for a bus at a certain bus stop has a uniform distribution over the interval from 0 to 25 minutes. (a) What is

trapecia [35]

Answer:

(a) The probability that a person has to wait less than 6 minutes for the bus is 0.24.

(b) The probability that a person has to wait between 10 and 20 minutes for the bus is 0.40.

Step-by-step explanation:

Let The random variable X be defined as the waiting time for a bus at a certain bus stop.

The random variable X follows a continuous Uniform distribution with parameters a = 0 and b = 25.

The probability density function of X is:

$f_{X}(x)=\left \{ {{\frac{1}{b-a};\ a$

(a)

Compute the probability that a person has to wait less than 6 minutes for the bus as follows:

$P(X$

$=\frac{1}{25}\times \int\limits^{6}_{0}{1}\, dx$

$=\frac{1}{25}\times [x]^{6}_{0}$

$=\frac{1}{25}\times [6-0]$

$=0.24$

Thus, the probability that a person has to wait less than 6 minutes for the bus is 0.24.

(b)

Compute the probability that a person has to wait between 10 and 20 minutes for the bus as follows:

$P10$

$=\frac{1}{25}\times \int\limits^{20}_{10}{1}\, dx$

$=\frac{1}{25}\times [x]^{20}_{10}$

$=\frac{1}{25}\times [20-10]$

$=0.40$

Thus, the probability that a person has to wait between 10 and 20 minutes for the bus is 0.40.

Find the equation of the line that has these features: slope, m=-6/5 passes through the point (-5,10)

frez [133]

We know that

the equation of the line is
y-y1=m(x-x1)
then
m=-6/5 passes through the point (-5,10)
y-10=(-6/5)*(x+5)-------> y-10=(-6x/5)-6------------> y=(-6x/5)+4---------> y=-1.2x+4

see the attached figure

the answer is
y=-1.2x+4

A farmer has decided to divide his land area in half in order to plant soy and corn. Calculate the area of the entire area so he

elena55 [62]

Well, using the equation
(top+bottom)/2*height
you get 54, and like in the picture, divide that by two to get 27
the farmer should buy two bags of corn, and two bags of soy, and will have quite a bit left over

Barry’s mountain bike weighs 6 pounds more than andy’s. Their bike weigh 42 pound together . Write an equation that represent th

Lina20 [59]

Hi there!

Let b equal the weight of Barry's mountain bike. Let a equal the weight of Andy's mountain bike.

b - 6 + b = 42

Since Barry's mountain bike weighs 6 pounds more than Andy's, we can say that Andy's mountain bike weighs b - 6 pounds. Since both mountain bikes added together is 42 pounds, b - 6 + b would be equal to 42.

Hope this helps!
