Answer:

only C is non-linear

Step-by-step explanation:

A linear equation is of the form;

y = mx + c

we have single powers of x and y; also, there is no product of x and y

Thus, we have;

a; 12x + 3y = 7

y =( -12x + 7)/3

this shows we have a linear equation

b. y + x = 4x + 5

y = 4x-x + 5

y = 3x + 5

This is a linear equation

c. y = 8/x^2

This is non-linear; we already have one power of x as 2

Answer:

$g(x)=-2\sqrt[3]x$

$g(x) = -2f(x)$

Step-by-step explanation:

Given

$f(x) = \sqrt[3]x$

Required

Write a rule for g(x)

See attachment for grid

From the attachment, we have:

$(x_1,y_1) = (-1,2)$

$(x_2,y_2) = (1,-2)$

We can represent g(x) as:

$g(x) = n * f(x)$

So, we have:

$g(x) = n * \sqrt[3]x$

For:

$(x_1,y_1) = (-1,2)$

$2 = n * \sqrt[3]{-1}$

This gives:

$2 = n * -1$

Solve for n

$n = \frac{2}{-1}$

$n = -2$

To confirm this value of n, we make use of:

$(x_2,y_2) = (1,-2)$

So, we have:

$-2 = n * \sqrt[3]1$

This gives:

$-2 = n * 1$

Solve for n

$n = \frac{-2}{1}$

$n = -2$

Hence:

$g(x) = n * \sqrt[3]x$

$g(x)=-2\sqrt[3]x$

or:

$g(x) = -2f(x)$

In Game 1, Emerson struck out 30 times in 90 times at bat. In Game 2, he struck out 40 times in 120 times at bat. In Game 3, Eme

VikaD [51]

Answer:

<u>Total number of strikeouts:</u>

30 + 40 + 42 = 112

<u>Total number of at bats:</u>

90 + 120 + 140 = 350

<u>Hits = times - strikeouts:</u>

350 - 112 = 238

<u>Percentage:</u>

238/352*100% = 67.61%

According to the American Community Survey, 27% of residents of the United States 25 years old or older had earned a bachelor de

oksian1 [2.3K]

a. The reason why this question is a binomial experiment is based on the fact that it is made up of an independent sample, it has a number that is fixed and a probability.

Each event is made up of two outcomes and they are random with the same success rate.

<h3>b. How to solve probability that exactly 5 had a bachelor</h3>

we have the following data n = 12, p = 0.27 and k = 5

We have to use the function to solve electronically

binompdf(n,p,k)

input the values

= binompdf(12,0.27,5)

This gives us

= 0.1255

<h3>(C) Probability that fewer than 5 have bachelor</h3>

We use the formula below

= binompdf(12,0.27,5-1)

This is = 0.7984

D. Probability of at least 5

1 - probability of fewer than 5

= 1 - 0.7984

= 0.2016

How to solve for the Mean = n*p

n = 12 , p = 0.27

Mean = 12*0.27 = 3.24

and

standard deviation = √npq

n = 12, p = 0.27 , q = 1- 0.27

= 0.73

sd = √12*.27*.73

= 1.54

(PLEASE GIVE GOOD ANSWER ILL GIVE BRAINLIEST)

Luba_88 [7]

Answer:

3.48%

Step-by-step explanation:

Probability = Area of hole / Area of board

= 3.14 x 2 x 2 / 12 x 30

= 12.56 / 360

= 0.0348

= 3.48%
