The area of his deck is 31 ft².

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

A square and a rectangle are in the given figure.

Now,

Square:

Side = 5 ft

Area = Side² = 5² = 25 ft²

Rectangle:

Length = 3 ft

Wide = 2 ft

Area = 3 x 2 = 6 ft²

Now,

Total area:

= 25 + 6

= 31 ft²

Thus,

The total area is 31 ft².

Answer:

10

Step-by-step explanation:

If n = 11 and p = 5, we can just substitute the values in for n and p in the equation 18 - n - 2 + p.

The new equation would be 18 - 11 - 2 + 5.

Using PEMDAS, we get the answer of 10.  

18 - 11 = 7

7 - 2 = 5

5 + 5 = 10

Using the binomial distribution, it is found that the variance of Alice's commuting time is of 2 minutes squared.

For each light, there are only two possible outcomes, either it is red, or it is green. The lights are independent of others, hence the binomial distribution is used to solve this question.

It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.

The variance of the binomial distribution is:

[tex]V(X) = np(1 - p)[/tex].

In this problem:

The variance for the number of red lights is:

V(X) = 4(0.5)(0.5) = 1

Since each red light delays Alice by exactly two minutes, the variance of Alice's commuting time is of:

2 x 1 = 2 minutes squared.

Answer:

m - 7.50 = 12.50

and

m = 7.50 + 12.50

Step-by-step explanation:

The best answers would be:

m - 7.50 = 12.50

and

m = 7.50 + 12.50

First of all, let's figure out what the question is asking us:

The question is asking us to find the amount of money on the gift card

It tells us to use "m" for "the amount of money on the gift card"

Now that we know the following, we can put together the equation

m = the amount of money on the gift card

$7.50 = cost of the book

$12.50 = amount remaining

Since he receives the gift card and then buys a book that costs $7.50, we are going to "have to subtract $7.50 from m". And we know that $12.50 is remaining, so we "make the equation equal to 12.50".

So, let's set up the equation:

m - 7.50 = 12.50

Now that we know the equation, we can solve for "m"

m - 7.50 = 12.50

Step 1: Add 7.50 to both sides.

m − 7.50 7.50 = 12.50 + 7.50

Step 2: Simplify

Answer: m = 20

Another way you can set up this equation is:

m = 7.50 + 12.50

Because we want to find "m", we set it equal to the equation. Since Salim bought a book for $7.50 and had $12.50 remaining, we want to find how much he had on the gift card that made him have $12.50 remaining when he bought the book. So, we have to add 7.50 and 12.50, to find how much is on the gift card.

So, the equation "m = 7.50 + 12.50", makes sense when solving for "m"

Hint: Once you have realized that the equation has Like Terms on the same side you must Combine the Like Terms by either adding them together or subtracting them.

Now that we know the equation, let's solve it

m = 7.50 + 12.50

Step 1: Combine like terms

m = (7.50 + 12.50)

m = 20

Since both equations equal $20 and both make sense, we can conclude that these are the best options.

Answer:

81°

Step-by-step explanation:

m(arc)JKL = 2m<E = 2(99°) = 198°

m(arc)JEL = 360° - m(arc)JKL

m(arc)JEL = 360° - 198° = 162°

m<K = (1/2)m(arc)JEL = 162°/2 = 81°

Answer:

12.9 m

Step-by-step explanation:

Let length = 3x, then breadth is 2x

if breadth is 8.6 m, so 2x = 8.6 m, x = 8.6/2 = 4.3 m

length = 3x = 3* 4.3 = 12.9 m

Answer:

x > 7

Step-by-step explanation:

Step 1: Subtract 5 from both sides.

Step 2: Divide both sides by -3.

Therefore, the answer is x > 7.

Answer:

X = 6

Step-by-step explanation:

-18 < 21
X = 6 since -3x is -18 and negative cancels each other

Additional comment

All spreadsheets have probability functions built in. Many graphing calculators are similarly capable of giving area from probability, or probability from area. A TI-84 requires two limits. In most cases, an upper limit of about 10 standard deviations from the mean (here, 3000 kWh) will work just fine. It tells me ...
