3 0

Answer:

x1 y1 x2 y2

(2 5) (-1 -4)

slope m = (y2-y1)/(x2-x1)

( -4 -5 )/( -1 -2 )

( -1/ -1 )

m= -1/-1

If 75 is added to a number, the result is 39 less than three times the number.find the number
Luba_88 [7]

First, we would set the number to x.

Then, we turn the words into an equation.

x+75 = 3x-39

Isolate the x.

-2x = -114

So...

x = 57

Will give brainliest whats the answer to #11
g100num [7]

The Alpitude is 5 because that is what the positive slope is. The Vertex is (2,6) because that is the lowest point on the graph. The equation is

y=5lx-2l-6 (lx-2l reprsents the absolute value of x-2)

If you roll two number cubes 100 times, about how many times can you expect the product to be a multiple of 6? (Example 6, 12, 1
KonstantinChe [14]

Using the binomial distribution, it is found that you could expect the product to be a multiple of 6 about 39 times.

For each trial, there are only two possible outcomes, either the result is a multiple of 6, or it is not. The result of each trial is independent of any other trial, hence the <em>binomial distribution</em> is used to solve this question.

<h3>What is the binomial probability distribution?</h3>

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

The expected value of the binomial distribution is:

E(X) = np

In this problem:

  • When two cubes are tossed and their products multiplied, there are 36 possible outcomes. Of those, (1,6), (2,3), (2,6), (3,4), (3,6), (4,3), (4,6), (5,6), (6,1), (6,2), (6,3), (6,4), (6,5), (6,6), that is, 14 result in a multiplication multiple of 6, hence p = 14/36.
  • There will be 100 trials, hence n = 100.

Then, the <em>expected value</em> is given by:

E(X) = np = 100 \times \frac{14}{36} = 38.89

Rounding up, you could expect the product to be a multiple of 6 about 39 times.

If the points (2,7),(-3,3) and (5,1) are the vertices of a triangle ,find the length of the median drawn through the first verte
Bingel [31]

Answer:

  • \sqrt{26} units

Step-by-step explanation:

The median is the line segment connecting the vertex with the midpoint of the opposite side.

<u>The midpoint has coordinates:</u>

  • x = (-3 + 5)/2 = 2/2 = 1
  • y = (3 + 1)/2 = 4/2 = 2

<u>Use the distance formula to find the distance between points (2, 7) and (1, 2):</u>

  • <u />d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}
  • d=\sqrt{(1- 2)^2+(2-7)^2} =\sqrt{1+25} =\sqrt{26}

Which set of side lengths cannot make a triangle?
Ket [755]

Answer:

Option "A" is correct answer to the following question.

Step-by-step explanation:

We know that, in triangle sum of two smaller lines ≥ largest side

So,

3 cm + 3 cm < 6 cm   [Not correct to the given situation.]

3 cm + 4 cm > 5 cm [Correct]

3 cm + 5 cm > 7 cm [Correct]

3 cm + 6 cm > 6 cm [Correct]
