Answer:

0.2696

Step-by-step explanation:

Number of People who responded Yes=175

Number of People who responded No=474

Total Number of Respondents=175+474=649

We want to determine the Probability that a person chosen at random believes that psychic can help solve murder cases.

Now,

Probability=\frac{Number of Possible Outcome}{Total Number of Outcomes}

Number who believe psychic can help solve murder cases=175

Total Number=649

Therefore:

P(a person chosen at random person believes some psychics can help solve murder cases) = \frac{175}{649}=0.2696

Find the slope, Y-intercept, and equation (make sure there is no decimals if there is a decimal make it into a fraction)!
adelina 88 [10]

Answer:

Slope is 5/3

y-intercept = -3

y = 5/3x - 3

Step-by-step explanation:

To find the slope, take to coordinates and use the equation below

m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}

7-2 = 5

6-3= 3

Now you have your slope which is 5/3

Then take the slope and input it into point slope form to get your y-intercept.

y-y₁=m(x-x₁)

y-2 = 5/3(x-3)

y-2=5/3x-5

add two to both sides to get Y by itself

y = 5/3x - 3

now you have your y-intercept, which is -3

Then check your answer by inputing two different coordinates for X and Y

7 = 5/3(6)-3

7=7

12= 5/3(9)-3

12=12

Solve x2 = 12x – 15 by completing the square. Which is the solution set of the equation?
REY [17]
X ·2 = 12x - 15

2x = 12x - 15

2x + (-12x) = (12x - 15) + (-12x)

Result: x = 3/2
