Answer 1

Answer:

false

Step-by-step explanation:

-5,-4,-3,-2,-1,0,1,2,3,4,5

Answer 2

FALSE

Step-by-step explanation:

because in the number line the difference between -5and 5 is 10 because when we put those numbers in number line the distance from 0 to 5 is 5 and the distance from 0 to -5 is 5 addition of this two distances will give us 10 because we do not cosider about direction they found in distance

There are supposed to be ____ biscuits in a frozen package, but there could be as many as _____ extra or _____ fewer in each bag, depending on the weight of the biscuits. Solving the equality will give the highest and lowest amounts of biscuits in the bag.

Answers

Answer:

13, 4, and 4

Step-by-step explanation:

The absolute value of a difference measures the discrepancy between the two numbers inside. The 13 represents the ideal amount of biscuits and x represents the actual number of biscuits in the package. So the difference between the actual and the ideal is 4 (whether it's 4 more of 4 less than 13).

The situation described doesn't actually match the wording, because this says there'll either be 9 or 17 biscuits in the package, due to the "=". If you wanted to have "as many as," then this should be "≤", allowing for 4 or fewer in either direction.

A student is planning on factoring 4x2 + 36 using difference of two squares (DOTS). Explain why this is an inappropriate method for factoring this expression. Then rewrite the expression by factoring out the greatest common factor (GCF).

Answers

This method is not appropriate because of the mathematical sign separating the terms. It is supposed to be minus not a plus sign

The expression by factoring out the greatest common factor is 4(x^2-9)

Given the expression 4x^2 + 36. According to the difference of two square,

a^2 - b^2 = (a-b)(a+b)

For the expression 4x^2 + 36, this can also be written as:

= (2x)^2 + 6^2

= (2x+6)(2x-6)

This method is not appropriate because of the mathematical sign separating the terms. It is supposed to be minus not a plus sign

Using the factoring method:

4x^2 = 4 * x^2

36 = 4 * 9

Since 4 is common to both of the terms, hence;

4x^2 + 36 = 4(x^2+9)

Hence the expression by factoring out the greatest common factor is 4(x^2-9)

What is Function?

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Given is a piecewise function.

Piecewise functions are function which has different values for different intervals.

Here the two pieces of the function corresponds to the intervals x > 1 and x ≤ 1.

Since the closed circle is over the curve below, we denote the interval x ≤ 1.

Now, from the options, the intervals x > 1 and x ≤ 1 are mentioned in options B and C.

For, x > 1, the graph is increasing. That is, as x value increases y value must increase.

So the equation cannot be x³ - 4.

Hence the option is C.

Hence the correct option is C.

Some news organizations maintain a database of customers who have volunteered to share their opinions on a variety of issues. Suppose that one of these databases includes 9000 registered voters in California. To measure the amount of support for a controversial ballot issue, 1000 registered voters in California are randomly selected from the database and asked their opinion. Which of the following is the largest population to which the results of this survey should be generalized?

a. The 1000 people in the sample
b. The 9000 registered voters from California in the database -> this is the right answer
c. All registered voters in California
d. All California residents
e. All registered voters in the United States

Answers

Using sampling concepts, it is found that the correct option is:

b. The 9000 registered voters from California in the database.

Example of sampling, involving sample and population:

I survey 1000 randomly selected residents of New York State, asking if they are Buffalo Bills fans or not.

The sample is the 1000 residents surveyed.The population is all New York State residents, as it is the pool with all available options to be sampled.

In this problem, 1000 registered voters in California are randomly selected from the database and asked their opinion, hence:

The 1000 voters are the sample.The pool with all available options to be sampled is the 9000 registered voters in California from the database, hence, it is the population, and option b is correct.

Plse Help! I'll mark brianleist! A store sells 3000 Halloween-themed wigs at $30 each every month. For each $1 increase in price, they would sell 75 less wigs. What is the price that would minimize the store's revenue? What is the maximum revenue?
PLease show all your work, thank you

Answers

Answer:

$15

Step-by-step explanation:

The price that would minimize the store's revenue is $30 + $35 = $65 (a price increase of $35). The maximum revenue is $170,625.

To find the price that would minimize the store's revenue, we need to determine the price at which the wig sales would be maximized.

Let's assume the price increase in dollars is represented by "x" (where x > 0).

The number of wigs sold can be calculated using the given information: for each $1 increase in price, 75 fewer wigs are sold.

So, the number of wigs sold at the price of $30 + x would be 3000 - 75x.

The revenue is calculated by multiplying the price per wig by the number of wigs sold. Therefore, the revenue function (R) can be expressed as:

R = (30 + x)(3000 - 75x)

To find the price that would minimize the store's revenue, we need to find the value of x that minimizes the revenue function. We can do this by finding the critical points of the revenue function.

To find the critical points, we differentiate the revenue function with respect to x and set it equal to zero:

dR/dx = 0

Differentiating R = (30 + x)(3000 - 75x) with respect to x:

dR/dx = (3000 - 75x) + (30 + x)(-75) = 0

Expanding and simplifying:

3000 - 75x - 2250 - 75x = 0

Combine like terms:

-150x - 5250 = 0

Solving for x:

-150x = 5250

x = 5250 / (-150)

x = -35

Since x represents the price increase, a negative value of x would correspond to a price decrease. So, the price that would minimize the store's revenue is $30 - $35 = -$5 (a price decrease of $5).

However, a negative price is not practical in this context. So, we should consider the price increase instead.

Therefore, the price that would minimize the store's revenue is $30 + $35 = $65 (a price increase of $35).

To find the maximum revenue, we can substitute this price ($65) back into the revenue function:

R = (30 + 35)(3000 - 75 * 35)

Simplifying:

R = 65 * 2625

R = $170,625

Therefore, the maximum revenue is $170,625.
