Answer:

f(x)=\sqrt{x-1} -----> Graph C

f(x)=\sqrt{x} -----> Graph A

f(x)=\sqrt{x}-1 -----> Graph B

f(x)=-\sqrt{x} -----> Graph D

f(x)=-\sqrt{x-1} -----> Graph E

Step-by-step explanation:

we have

case a) f(x)=\sqrt{x-1}

Find the domain

we know that

The radicand must be greater than or equal to zero

so

x-1\geq 0

x\geq 1

The domain is the interval -----> [1,∞)

All real numbers greater than or equal to 1

The range is the interval ----->  [0,∞)

All real numbers greater than or equal to 0

case b) f(x)=\sqrt{x}

Find the domain

we know that

The radicand must be greater than or equal to zero

so

x\geq 0

The domain is the interval -----> [0,∞)

All real numbers greater than or equal to 0

The range is the interval ----->  [0,∞)

All real numbers greater than or equal to 0

case c) f(x)=\sqrt{x}-1

Find the domain

we know that

The radicand must be greater than or equal to zero

so

x\geq 0

The domain is the interval -----> [0,∞)

All real numbers greater than or equal to 0

The range is the interval ----->  [-1,∞)

All real numbers greater than or equal to -1

case d) f(x)=-\sqrt{x}

Find the domain

we know that

The radicand must be greater than or equal to zero

so

x\geq 0

The domain is the interval -----> [0,∞)

All real numbers greater than or equal to 0

The range is the interval ----->  (-∞,0]

All real numbers less than or equal to 0

case e) f(x)=-\sqrt{x-1}

Find the domain

we know that

The radicand must be greater than or equal to zero

so

x-1\geq 0

x\geq 1

The domain is the interval -----> [1,∞)

All real numbers greater than or equal to 1

The range is the interval ----->  (-∞,0]

All real numbers less than or equal to 0

kumpel [21]

Answer:

<u>The correct answer is A. Credit card bill and B. Car loan</u>

Step-by-step explanation:

Let's recall that we consider a personal or familiar liability an obligation to pay money you or your family owe to another person or financial institution like a bank. Liabilities can be classified according to the term, either short such as a credit card or loan from the bank with one-year term, or long such as a car loan or mortgage.

According to that definition, Tricia's liabilities are A. Credit card bill and B. Car loan.

Chain complete 40% of her homework on Monday and 2/3 on Tuesday if she started her homework on Monday what fractional part of he
kotykmax [81]

Answer:

1/5

Step-by-step explanation:

For Monday

The fraction of homework Chain completed =

40% of her homework

= 40% = 40/100

= 2/5

For Tuesday

The amount of home work left =

= 1 - 2/5

3/5

The fraction of homework Chain completed on Tuesday = 2/3

= 2/3 Of 3/5

= 2/3 × 3/5

= 2/5

Let the total complete homework be represented by 1

Hence:

The Fractional part of her homework left for her to complete after Tuesday =

1 - (2/5 + 2/5)

Lowest common denominator is 5

= 1 - (2 + 2/5)

= 1 - (4 /5)

= 1/5

Anyone please help!!!
Tanya [424]

Problem 1

Answers:

Percentage of patients that were dogs = 46%

Standard Error = 0.07048404074682

Margin of error for 90% confidence interval = 0.11594624702851

Margin of error for 95% confidence interval = 0.13814871986377

Round the decimal values however you need them

------------

To get the first answer, you add up the numbers given (7,4,5,5,2) and divide that over 50. So 7+4+5+5+2 = 23 which leads to 23/50 = 0.46 = 46%; therefore phat = 0.46 is the sample proportion of dogs.

Use the SE (standard error) formula given to you with phat = 0.46 and n = 50 to get SE = 0.07048404074682

The critical z value at 90% confidence is 1.645; this value is found in your Z table (back of your stats textbook). Multiply the SE value by 1.645 to get 0.07048404074682*1.645 = 0.11594624702851

Also found in your textbook is 1.960 which is the z critical value at 95% confidence. Multiply this with the SE value to get 0.07048404074682*1.960 = 0.13814871986377

===============================================

Problem 2

Answer: Choice B) picking balls from a bin; the 60 randomly selected get chosen for the first bus, while the remaining 60 go to the second bus

-----------

Choice A is fairly vague on what the lower and upper boundaries are. What is the smallest number allowed? What about the largest? This isn't clear so it's possible that we could end up with more positive numbers than negative (eg: if we had an interval -10 < x < 110). So choice A is false. A similar issue shows up with choice D.

Choice B is true. Assuming the selection process is random and not biased, then each ball is equally likely for each selection. The fact that the balls are colored seems to be extra info which I'm not sure why your teacher threw that in there.

Choice C is false because choice B is true

Choice D is false for similar reasons as choice A. It's not clear where we start and where we end. If we had the interval 2 < x < 6 then x could take on the values {3, 4, 5} and we see that picking an odd number is twice as likely than picking an even. In this example, there is bias.

===============================================

Problem 3

Answer: Choice B) Roll a die; each number corresponds to a different class

------------

Choice A is false because choice B being the answer contradicts it

Choice B is true: there are 6 sides on the die, and each side is equally likely to be landed on, so each class is equally likely

Choice C is false because 2*2*2 = 8 represents the number of combos you can have when you flip three coins (one combo being HTH for heads tail heads) but there are 6 classes, not 8

Choice D is false because while we want 6 regions on the spinner. Each region must have the same area; otherwise, one class is weighted heavier than the others making it more likely you select that particular class.
