A function f(x)f(x) is graphed on the coordinate plane.

Effectus [21]

Answer

-4x - 2

Explanation

To get the function needed, first calculate the slope of the graph.

slope = (change in y) / (change in x)

= (2 - -2)/(-1 - 0)

= 4/-1

= -4

Now use one of the point (-1, 2) in the graph and a general point (x,y) to find the function.

-4 = (y - 2)/(x - -1)

-4(x + 1) = y - 2

-4x - 4 = y - 2

y = -4x - 4 + 2

= -4x - 2

∴ f(x) = -4x - 2

Solve, be sure to show each step under the original problem for any credit. 1 =k/12 +5

Naya [18.7K]

K = -48

1. subtract 5 from both sides
-4 = k/12

2. multiply 12 from both sides to get k alone
-48 = k

What proportion of students are willing to report cheating by other students? A project put this question to an SRS of 180 under

krok68 [10]

Answer:

13.89% of students are willing to report cheating by other students.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 180

Number of students who reported cheating, x = 25

We have to find the proportion of the students are willing to report cheating by other students.

Proportion of students can be calculate as

$p = \dfrac{x}{n} = \dfrac{25}{180} = 0.1389\\\\\p = 0.1389\times 100\5\\p = 13.89\%$

Thus, 13.89% of students are willing to report cheating by other students.
