Can someone plz help me with this?

Answer:

d= (-11-2)^2 + (-12--12)^2

d= (-13)^2 + (0)^2

d=169

square root the 169

answer is 13

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

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.

Step-by-step explanation:

y = 5 + 2x^2

if x =1

y = 5 + 2(1)^2

1^2 = 1

2 x 1 = 2

y=5 + 2 or y = 7

you substatute each one in for x to solve for y

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

Answer:

L = 25 m

Step-by-step explanation:

L = 4W - 3

perimeter = 2(L + W)

64 = 2(4W - 3 + W)

divide both sides by 2:

32 = 5W - 3

add 3 to each side:

5W = 35

divide both sides by 5:

W =7

L = 4(7) - 3 = 25

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:

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.

Sentence structure needs to simple, standalone, Grammarly justified and able enough to convey the writer thoughts and feelings clearly

Step-by-step explanation:

Sentence structure is very essential to convey the idea of the writer clearly. It is just like the skeleton of a write up and hence its framework needs to be clear and able enough to express the real sense. The structure of sentence needs to be complete with adequate grammar and punctuations. A good sentence must be able to express a complete idea  on its own.
