Answer:

identification from the table given below. use y = mx + c to solve

Step-by-step explanation:

y = 3x  to third

y = 1.5x -7 to second  

y =7 to first

y = -1.5x-4 to fifth

y = -3x+4 to fourth

Answer:

Below!

Step-by-step explanation:

Let's use the formula to identify the correct slope and y intercept.

We know that:

Formula = y = mx + b__________________________________________________

Option 1: (y = 3x)

Let's compare y = 3x with the formula.

(y = 3x) = (y = mx + b)

We can clearly see that the slope(m) is 3 and the y-intercept(b) is 0.

Final answer: m = 3, b = 0

__________________________________________________________

Option 2: (y = 1.5x - 7)

Let's compare y = 1.5x - 7 with the formula.

(y = 1.5x - 7) = (y = mx + b)

We can clearly see that the slope(m) is 1.5 and the y-intercept(b) is -7.

Final answer: m = 1.5, b = -7

__________________________________________________

Option 3: (y = 7)

Let's compare y = 7 with the formula.

y = 7 = (y = mx + b)

We can clearly see that the slope(m) is 0 and the y-intercept(b) is 7.

Final answer: m = 0, b = 7

__________________________________________________

Option 4: (y = -1.5x - 4)

Let's compare y = -1.5x - 4 with the formula.

(y = -1.5x - 4) = (y = mx + b)

We can clearly see that the slope(m) is -1.5 and the y-intercept(b) is -4.

Final answer: m = -1.5, b = -4

__________________________________________________

Option 5: (y = -3x + 4)

Let's compare y = -3x + 4 with the formula.

(y = -3x + 4) = (y = mx + b)

We can clearly see that the slope(m) is -3 and the y-intercept(b) is 4.

Final answer: m = -3, b = 4

Answers

The ratio of the two point is the coordinate at the plane where the two point are divided at the fixed amount of length. The y value of the point that is 3/4 distance from point E to point F is -1.5. thus the option 4 is the correct option.

Given information-

The coordinates of the point E is (2,-3).

the coordinates of the point F is (-2,-1).

As the 3/4 the distance from the point E is the point F is means the points which divides the line EF in the ratio of 3/1.

Ratio of two point

The ratio of the two point is the coordinate at the plane where the two point are divided at the fixed amount of length.

Suppose the ratio [tex]m:l [/tex] are the ratio of the two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. Then the coordinate of the point which divide the line at this ratio can be given as,

[tex](x,y)=\left ( \dfrac{mx_2+lx_1\tiems}{m+l} ,\dfrac{my_2+ly_1}{m+l} \right )[/tex]

Put the values,

[tex](x,y)=\left ( \dfrac{3\times (-2)+1\times(2)}{3+1} ,\dfrac{3\times (-1)+1\times(-3)}{3+1} \right )[/tex]

[tex](x,y)=(-1,-1.5)[/tex]

Thus the y value of the point that is 3/4 distance from point E to point F is -1.5. thus the option 4 is the correct option.

A basketball player has made 80​% of his foul shots during the season. Assume the shots are independent.
​a) What's the expected number of shots until he​ misses?
​b) If the player shoots 15 foul shots in the fourth​ quarter, how many shots do you expect him to​ make?
​c) What is the standard deviation of the 15 ​shots?

Answers

Using the binomial distribution, it is found that:

a) The expected number of shots until he​ misses is of 5.

b) You expect him to make 12 shots.

c) The standard deviation is of 1.55 shots.

What is the binomial probability distribution?It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.

The expected number of trials until q failures is:

[tex]E_f(X) = \frac{q}{1 - p}[/tex]

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

In this problem:

A basketball player has made 80​% of his foul shots during the season, hence [tex]p = 0.8[/tex].

Item a:

Miss one shot, hence one failure, that is, [tex]q = 1[/tex].

[tex]E_f(X) = \frac{1}{0.2} = 5[/tex]

Item b:

The player takes 15 shots, hence [tex]n = 15[/tex].

[tex]E(X) = np = 15(0.8) = 12[/tex]

Item c:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{15(0.8)(0.2)} = 1.55[/tex]
