From what I can see with this picture, it seems like theyre asking for percentages of one number, to take a percentage of a number you convert the percent to a decimal, so 10% is equal to 10/100 = .10, so 200 * .10 = 20

Which of the following are continuous variables, and which are discrete? (a) number of traffic fatalities per year in the state

sukhopar [10]

Answer:

a) Discrete

b) Continuous

c) Continuous

d) Discrete

e) Continous

Step-by-step explanation:

Continuous:

Real numbers, can be integer, decimal, etc.

Discrete:

Only integer(countable values). So can be 0,1,2...

(a) number of traffic fatalities per year in the state of Florida

You cannot have half of a traffic fatality, for example. So this is discrete

(b) distance a golf ball travels after being hit with a driver

The ball can travel 10.25m, for example, which is a decimal number. So this is continuous.

(c) time required to drive from home to college on any given day

You can take 10.5 minutes, for example, which is a decimal value. So this is continuous.

(d) number of ships in Pearl Harbor on any given day

There is no half ship, for example. So this is discrete.

(e) your weight before breakfast each morning continuous discrete

You can weigh 80.4kg, for example, which is a decimal number. So this is continuous.

yKpoI14uk [10]

Answer:

6 ≤ x ≤ 7

Step-by-step explanation:

Dividing 52 by 8 gives you a decimal between 6 and 7. Since you can only but hamburgers in packages of 8, the inequality is 6 ≤ x ≤7 with x being the number of hamburger bags.

Can somone pls explain what i did wrong, and the correct answer?? ( Parallel/Perpendicular Through Points algebra. write how to

DENIUS [597]

The two linear equations are:

1) y = -x + 5

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

<h3></h3><h3>How to get the linear equations?</h3>

Remember that two linear equations are parallel if and only if have the same slope and different y-intercept.

So to find a linear equation:

y = m*x + b

Parallel to:

x + y = 4

y = -x + 4

The slope needs to be m = -1 and the y-intercept b ≠ 4

So our line will be:

y = -x + b

To find the value of b, we use the fact that this line passes through (2, 3), replacing the values of the point in the line we get:

3 = -2 + b

3 + 2 = b

5 = b

The linear equation is y = -x + 5

For the second case, we want to find a line perpendicular to:

2x - y = 5

y = 2x - 5

Two lines are perpendicular if the product of the slopes is -1, then:

m*2 = -1

m = -1/2

So the perpendicular line is something like:

y = (-1/2)*x + b

To find the value of b we use the fact that this line needs to pass through (6, -4)

Replacing these values we get

-4 = (-1/2)*6 + b

-4 = -3 + b

-4 + 3 =b

-1 = b

The line is:

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

A survey of 1000 high school students found that 781 students own a cell phone and 133 of those students who own a cell phone al

kirza4 [7]

This question is not complete. Find attached the complete question and the figure showing the two way table.

Answer:

a. P(owns a cellphone) = 781/1000

b. P(does not own a PS4) = 421/500

c. P(owns a PS4 U does not own a cellphone) = 377/1000

d. P(owns a PS4 n does not own a cellphone) = 25/158

e. P(owns a PS4 | own a cell phone) =

158/1000

f. P(owns a cellphone | own a PS4) = 781/1000

Step-by-step explanation:

Total number of students = 1000 students

We have two variables,

1. The students who own cellphones

2. The students who own PS4

a. P(owns a cellphone)

From the question and the table, we are told that 781 people own cellphones.

Hence, P(owns a cellphone) = 781/1000

b. P(does not own a PS4)

From the attached table, we can see that the number of students that does not own a PS4 = 842

Hen P(does not own a PS4) = 842/1000 = 421/500

c. P(owns a PS4 U does not own a cellphone) =

First we find the Probability of student that owns a PS4

Number of students that own a PS4 = 158

P(owns a PS4 ) = 158/1000

Number of students that does not own a cell phone = 219

P(does not own a cell phone) = 219/1000

Therefore, P(owns a PS4 U does not own a cellphone) = P(owns a PS4 ) + P(does not own a cell phone)

= 158/1000 +219/1000

= 377/1000

d. P(owns a PS4 n does not own a cellphone) =

From the table, we obtain that as =

25/158

e. P(owns a PS4 | own a cell phone) =

P(owns a PS4 n own a cell phone) ÷ P(own a cell phone)

= P(owns a PS4)

From the table that would give us = 158/1000

f. P(owns a cellphone | own a PS4) =

P(owns a cellphone n own a PS4) ÷ P(own a PS4)

= P(owns a cellphone

From the table, this is given as :

781/1000
