Answer:2

Step-by-step explanation:toke the test

The number of units away from each of the points from the y-axis will be 2.

It is the measure of distance between the two points and is known as length. The length is measured in meters generally.

Let one point be (x, y) and another point be (h, k).

Then the distance between the points will be

D² = (x - h)² + (y - k)²

The points are given below.

A(-2, 3) and B(2, 3)

The coordinate of the points that lie on the y-axis is (0, 3).

Then the distance from point A will be given as,

D² = (-2 + 0)² + (3 - 3)²

D² = 4

D = 2

Then the distance from point B will be given as,

D² = (2 + 0)² + (3 - 3)²

D² = 4

D = 2

The number of units away from each of the points from the y-axis will be 2.

Answer:

0.006795

Step-by-step explanation:

Note: The table of the question is attached as picture below

Total number of heavy smokers = 36+ 37 = 73

Total men and women = 880

We need to know the probability of selecting two DIFFERENT heavy smokers.

Probability of (First person selected is a heavy smoker) = 73/880

Discarding the first person, now you have 879 subjects left and 72 heavy smokers left.

So, Probability of Second person selected is a heavy smoker) = 72/879

Probability of 2 different people selected are heavy smokers) = 73/880 * 72/879

= 5256 / 773520

= 0.006795

Answer:

The remaining lenghts are [tex]x = 20.364\,cm[/tex] and [tex]y = 12.925\,cm[/tex].

Step-by-step explanation:

Given that there are two triangles opposite to each other and between two parallel lines, then both are similar, meaning than following relationships exist:

[tex]\frac{AC}{CD} = \frac{BC}{CE} = \frac{AB}{DE}[/tex] (1)

If we know that [tex]AC = 11\,cm[/tex], [tex]CD = 28\,cm[/tex], [tex]BC = 8\,cm[/tex] and [tex]DE = 32.9\,cm[/tex], then the missing lengths are, respectively:

[tex]\frac{11\,cm}{28\,cm} = \frac{8\,cm}{x}[/tex]

[tex]x = \frac{(28\,cm)\cdot (8\,cm)}{11\,cm}[/tex]

[tex]x = 20.364\,cm[/tex]

[tex]\frac{11\,cm}{28\,cm} = \frac{y}{32.9\,cm}[/tex]

[tex]y = \frac{(11\,cm)\cdot (32.9\,cm)}{28\,cm}[/tex]

[tex]y = 12.925\,cm[/tex]

The remaining lenghts are [tex]x = 20.364\,cm[/tex] and [tex]y = 12.925\,cm[/tex].

The value of a from the given mathematical expression is 5.1.

Given the following data:

To determine the value of a:

In this exercise, you're required to solve for the value of a from the given mathematical expression. Since the two (2) mathematical expressions are equivalent (equal), we would go ahead to equate them as follows:

[tex]2.4x-3.9y-1.2x+ay = 1.2x+1.2y[/tex]

Simplifying the equation, we have:

[tex]2.4x-3.9y-1.2y+ay-1.2x-1.2x = 0 \\\\2.4x-5.1y+ay-2.4x = 0\\\\-5.1y+ay=0\\\\ay=5.1y[/tex]

Given that Li is making beaded necklaces for each necklace, she uses 27 spacers, plus 5 beads per inch of necklace length.

The equation to find how many beads Li needs for each necklace can be obtained as follows:

A. The input variable is the number of inches of the necklace length (x).

B. The output variable is the number of beads Li needs for each necklace (y).

C. The required equation is given by

Answer:

the lenght of the shortest side is 12

Step-by-step explanation:

So first add them all up becuase perimeter

3x+3x+5x-4+5x-4

You’ll get 16x-8

16x-8=56

16x=64

x=4

So then plug it in

3x=3*4=12

5x-4=5*4-4=16

so 12 is the shortest side

Answer:

-$0.15

Step-by-step explanation:

We have been given win = $10, and loss = $-1

This deck of cards has 4 aces out of a total of 52 cards.

Then the probability can be explained as the number of favorable outcome/number of what is the possible outcome.

P(win) = number of favorable outcome/number of possible outcome

= 4/52

= 1/13

P(loss) = number of favorable outcome/number of possible outcome

= 48/52

= 12/13

Then we have

$10x1/13 + (-1)x12/13

= 10/13-12/13

= -2/13 dollars

= -$0.15

Using the principle of discrete probability, the expected value, which a measure of the mean amount after many plays is - 2/13

Calculating the required probabilities :

P(winning) = P(drawing an Ace) = 4/52 = 1/13

Hence, P(losing) = 1 - 1/13 = 12/13

X :____ 10 _____ - 1

P(X) : _ 1/13_____ 12/13

The expected value :

E(X) = 10 × (1/13) + - 1(12/13)

E(X) = 10/13 - 12/13

E(X) = - 2/13

Hence, the measure of the mean amount is -2/13.
