The perimeter of a rectangle is 38m. The length is 3m more than times the width. Find the length and the width of the rectangle.

Answers

Answer:

Width = 4.75

Step-by-step explanation:

Step 1:

P = 2 ( L + W )

Step 2:

38 = 2 ( 3w + w )

Step 3:

38 = 6w + 2w

Step 4:

38 = 8w

Answer:

4.75 = w

A home security system is designed to have a 99% reliability rate. Suppose that nine homes equipped with this system experience an attempted burglary. Find the probabilities of these events:_________.A. At least one alarm is triggered.
B. More than seven alarms are triggered.
C. Eight or fewer alarms are triggered.

Answers

Answer:

a) P(X \geq 1) = 1-P(X<1) = 1-P(X=0)

P(X=0)=(9C0)(0.99)^0 (1-0.99)^(9-0)=1x10^(-18)

And replacing we got:

P(X \geq 1) =1 -1x10^(-18) \approx 1

b) P(X=7)=(9C7)(0.99)^7 (1-0.99)^(9-7)=0.003355

P(X=8)=(9C8)(0.99)^8 (1-0.99)^(9-8)=0.083047

P(X=9)=(9C9)(0.99)^9 (1-0.99)^(9-9)=0.913517

And adding we got:

P(X \geq 7) = 0.003355+0.083047+0.913517 =0.99992

c) P(X \leq 8) =1 -P(X>8) = 1-P(X=9)

P(X=9)=(9C9)(0.99)^9 (1-0.99)^(9-9)=0.913517

And replacing we got:

P(X \leq 8)= 1-0.913517=0.086483

Step-by-step explanation:

Let X the random variable of interest "numebr of times that an alarm is triggered", on this case we now that:

X \sim Binom(n=9, p=0.99)

The probability mass function for the Binomial distribution is given as:

P(X)=(nCx)(p)^x (1-p)^(n-x)

Where (nCx) means combinatory and it's given by this formula:

nCx=(n!)/((n-x)! x!)

Part a

We want to find this probability:

P(X \geq 1) = 1-P(X<1) = 1-P(X=0)

P(X=0)=(9C0)(0.99)^0 (1-0.99)^(9-0)=1x10^(-18)

And replacing we got:

P(X \geq 1) =1 -1x10^(-18) \approx 1

Part b

P(X \geq 7)= P(X=7) +P(X=8)+ P(X=9)

P(X=7)=(9C7)(0.99)^7 (1-0.99)^(9-7)=0.003355

P(X=8)=(9C8)(0.99)^8 (1-0.99)^(9-8)=0.083047

P(X=9)=(9C9)(0.99)^9 (1-0.99)^(9-9)=0.913517

And adding we got:

P(X \geq 7) = 0.003355+0.083047+0.913517 =0.99992

Part c

P(X \leq 8) =1 -P(X>8) = 1-P(X=9)

P(X=9)=(9C9)(0.99)^9 (1-0.99)^(9-9)=0.913517

And replacing we got:

P(X \leq 8)= 1-0.913517=0.086483

Mrs. Grudman bought a dishwasher at a special sale. The dishwasher regularly sold for$912. No down payment was required. Mrs. Grudman has to pay $160 for the next six
months. What is the average amount she pays in interest each month?

Answers

The average amount she pays in interest each month will be $8.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The dishwasher regularly sold for $912.

No down payment was required.

Mrs. Grudman has to pay $160 for the next six months.

Now,

The total amount pay by Mrs. Grudman = 6 x $160

                                                             = $960

Thus, The average amount she pays in interest each month is;

= (960 - 912) / 6

= $8

Thus, The average amount she pays in interest each month will be $8.

Answer:

So let's take a look into the question, "Mrs. Grudman bought a dishwasher at a special sale. The dishwasher regularly sold for

$912. No down payment was required. Mrs. Grudman has to pay $160 for the next six months. What is the average amount she pays in interest each month?"

Step-by-step explanation:

So, " Mrs. Grudman has to pay $160 for the next six months" they want us to multiply, $160

              x

                    6

              _______

                  960

So, 960 is your answer. Hope this helps!
