Find the range of values for which
x2 - 6x + 8 < 0

Answers

Answer 1

Answer:

Step-by-step explanation:

Factor

x^2-6x+8<0

(x-2)(x-4)<0

For this to be less than zero the factors must have opposite signs.

x>2 and x<4

2<x<4

So x is all real numbers between 2 and 4 or in interval notation

x=(2,4)

The total bill for drinks and a pizza for three people is $14.90 before tax. The group wants to leave a 15% tip on the cost of the food, not including tax. What will be the amount of the tip?

Answers

Answer:

$2.24

Step-by-step explanation:

Since we are trying to find a percentage of something, we can multiply whatever we're trying to find a percentage from by 0.X where X is equal to the number of the percentage. So in this case it's 15%. We can multiply $14.90 by 0.15 and we get 2.23500. Since we cannot have 2.235 dollars, we must round up decimal places.

The tip would be 2 dollars and 24 cents. ($2.24).

Answers

You can solve this by taking 5% off of 28,000 and an additional 5% off of that.
.95 x 28,000 = 26,600
.95 x 26,600 = 25,270
In 2 months, the social networking site will have 25,270 users.

Mary is buying a case of water. She spends $7.99 for a case of 24 bottles. What is the unit rate? (Cost for 1 bottle) *

Answers

Answer:

so I'm not 100% sure but in these types of questions you are supposed to divide

so you have a pack of 24 bottles for 7.99

so you would do 7.99÷24 = 0.33

then to check it you can multiply

0.33× 24 bottles and it gives you 7.93 which is super close to 7.99 anyway I hope this helps ...

The function table below represents the linear function y = 4x – 3. Which answer represents the outputs of the function table

Answers

Answer:

Here we can not see the options, so i will answer in a general way.

When we have a function y = f(x), we define:

x as the input

y as the output.

so f(x) is some kind of "machine", in wich we put an input x, and the "machine" does something and returns an output y.

In, this case, we have:

y = f(x) = 4*x - 3

then if we give this function different inputs, we will get different ouputs.

for example, if we use the input x = 0, then the output is:

y = f(0) = 4*0 - 3 = -3

Then if we made a table for inputs and outputs, we will have the data:

[tex]\left[\begin{array}{ccc}inp&out\\x&y\\0&-3\end{array}\right][/tex]

We can rewrite this table in a general way as:

[tex]\left[\begin{array}{ccc}inp&out\\x&4*x - 3\end{array}\right][/tex]

This means that for every input x, the output is always 4*x - 3.

To complete this type of tables, we usually use different values of x, for example here I will use some different ones:

y = f(3) = 4*3 - 3 = 12 - 3 = 9

y = f(10) = 4*10 - 3 = 40 - 3 = 37

y = f(-1) = 4*-1 - 3 = -4 - 3 = -7

Then we will have a table like:

[tex]\left[\begin{array}{ccc}inp&out\\3&9\\10&37\\-1&-7\end{array}\right][/tex]

Concluding, the thing that will always represent the output of our function is: 4*x - 3.

Which value is MEAN of the data set?
A)
480
B)
485
500
D)
The MEAN cannot be determined from the available information.

Answers

Answer:

500

Step-by-step explanation:

I believe the answer is D) The mean cannot be determined from the available information.

The mean in math means the sum of all the numbers divided by how many numbers there are. There is no information about how many numbers there are nor any information of which numbers exist and which numbers don't.

The data set only tells us the first number, last number, and median-- things a box-and-whisker plot would tell us; perhaps a different way of representing data would work better to help us find the median like a dot plot or a bar graph.

If this is incorrect, please, don't refrain to tell me. Thank you.
