Following are the solution to the given question:

Step-by-step explanation:

Have a Spanish Jury possibility= 0.40

Jury member No. to be chosen= n= 12

Hispanic Juror Expected = np = 12\times 0.40 = 4.8

The jury group will be constituted by Hispanic Jurors 4.8

OR

The binomial distribution defines the behavior of a count variable X, provided:

There are a set number of data points n.

Set n=12

Each perception is independent. This will not affect others if your first juror is selected

One of two results is that each observation ("success" or "failure"). English or not

Each result has the same chance of "success" p. for every p=0.40

Well by the binomial distribution. Mean=E(x)=np=4.8

The length of a rectangle is 5 units more than the width. The area of the rectangle is 36 units. What is the length, in units, o
sergey [27]

Answer:

11 units

Step-by-step explanation:

Let's do it this way:

Length = l

width = w

initial equation for area is l * w

We know that l = w+5

substitute.

w+5 * w = 36

solve.

6w = 36

w=6

The width is 6 units.

6+5 = 11

length = 11 units

Ravi ordered some books online and spent a total of $89. Each book cost $5 and he paid a total of $4 for shipping. How many book
Katyanochek1 [597]

Answer:

He bought 17 books.

Step-by-step explanation:

Given that:

Total money spent = $89

Cost of each book = $5

Shipping price = $4

We have to find, Total number of books

So if the number of books be represented by b, the equation will become:

Cost of one book * total number of books + shipping price = total money

Putting values we get:

5*b + 4 = $89

By simplifying:

5*b = 89 - 4

5*b = 85

Dividing both sides by 5 we get:

b = 17

So the total number of books bought is 17.

i hope it will help you!

Shay created the table below to graph the equation r-3-sin theta (rounded to the hundredths place). Analyze the table. Did Shay
monitta

Answer:

B is false

Step-by-step explanation:

Let's check Shay's table:

  • if \theta=0, then r=3-\sin 0=3-0=3 (true);
  • if \theta =\dfrac{\pi}{6}, then r=3-\sin \dfrac{\pi}{6}=3-\dfrac{1}{2}=2.5 (true);
  • if \theta = \dfrac{\pi}{4}, then r=3-\sin \dfrac{\pi}{4}=3-\dfrac{\sqrt{2}}{2}\approx2.29 (true);
  • if \theta=\dfrac{\pi}{3}, then r=3-\sin \dfrac{\pi}{3}=3-\dfrac{\sqrt{3}}{2}\approx 2.13 (false);
  • if \theta =\dfrac{\pi}{2}, then r=3-\sin \dfrac{\pi}{2}=3-1=2 (true).
