Answer:

Step-by-step explanation:

By definition, we will see that y is a binomial variable.

Here the variable "y" represents:

y = "number of kings drawn"

When we draw 7 cards out of a 52 cards deck.

So there are 5 possible values of y:

A binomial variable is a variable that represents two outcomes, for example, if we used the variable x = "drawing a king" 7 times, then x is a binomial variable, because it has two outcomes, or you draw a king, or you don't.

A binomial variable can also represent the number of outcomes of each type for several events like x (the one defined above). This is what y does, it counts how many times the outcome of "x" is "drawing a king" for a sequence of 7 draws.

Then y is a binomial variable.

that's the distance from (2, -12) (-11, -12)

hope that helps

Step-by-step explanation:

The distance between the points A ( 2 , -12 ) and B ( -11 , -12 ) is 13 units

What is the distance of a line between 2 points?

The distance of a line between 2 points is always positive and given by the formula

Let the first point be A ( x₁ , y₁ ) and the second point be B ( x₂ , y₂ )

The distance between A and B is D , and the distance D is

[tex]Distance D = \sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2} }[/tex]

Given data ,

Let the distance between the two points be = D

Let the first point be represented as = A

The value of A = A ( 2 , -12 )

The second point be represented as = B

The value of B = B ( -11 , -12 )

Now , the distance between the points A and B is given by the equation of distance formula

[tex]Distance D = \sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2} }[/tex]

Substituting the values in the equation , we get

[tex]Distance D = \sqrt{(-12-(-12)^{2} + (2-(-11))^{2} }[/tex]

On simplifying the equation , we get

[tex]Distance D = \sqrt{(0 + (2+11))^{2} }[/tex]

[tex]Distance D = \sqrt{(13)^{2} }[/tex]

[tex]Distance D = 13[/tex]

Therefore , the value of D is 13

Hence ,

The distance between the points A ( 2 , -12 ) and B ( -11 , -12 ) is 13 units

A resposta é -5, como diz na pergunta.

Answer:

Solve for X; whereas lb=pound, $=cost

1lb = $12.55

0.6lb = $X; therefore 6/10 lb = $X

Rewrite:

$12.55/1 lb = $X/6/10 lb; therefore $12.55/1 lb = 10/6(X); 10X=$12.55(6); 10X=$75.30; X=$75.30/10

X=$7.53 for .6 lbs.

Answer:

3 students

Step-by-step explanation:

Two ways you can do this:

1. If you have a graphic calculator you can find the normal distribution function and enter the following values to get the probability of a student finished in less than 5 minutes:

Lower: 0

Upper: 5

Standard Deviation: 1

Mean: 6

This gives a probability of: 0.1587 (4.d.p)

2. You can use the formula and find the probability using the Z-table.

[tex]Z = \frac{x - \mu}{\sigma}[/tex]

Substitute known values:

[tex]Z = \frac{5 - 6}{1}\\Z = -1/1 = -1\\[/tex]

It is one standard deviation to the left of the mean,.

Look up on Z-score table and we get: 0.1587 (4.d.p)

Now we need to find expected number. We do this by multiplying the probability by the amount of people:

0.1587 x x19 = 3.0153 rounded to 3 students.

Answer:

y = 12

Step-by-step explanation:

Look at the left triangle first.  Opposite the 30 degree angle (not shown) is the shortest side, which (according to the sine function) is half the hypotenuse, or 2√3.  Then (2√3)² + x² = (4√3)², or

4(3) + x² = 16(3).  Thus, x² = 16(3) - 4(3) = 12(3) = 36, and so x = 6.  Again using the sine function, we find that x = 2y = 6, so, using the sine function, we find that sin 30° = 6/y.  Thus y = 6 / (2/1) = 12  =  y
