Find the domain of the graphed function.

Answer:

Ryan has 10 pennies and 13 nickels.

Step-by-step explanation:

Let the number of pennies be p and the number of nickels be n.

We have two unknowns, the number of pennies and the number of nickels, so we need two equations. One equation will deal with the value of the coins. The other equation will deal with the number of coins.

Value of coins:

1 penny is worth $0.01; p pennies are worth 0.01p.

1 nickel is worth $0.05; n nickels are worth 0.05n.

The total amount the coins are worth is

0.01p + 0.05n

The coins are worth $0.75, so we have our first equation.

0.01p + 0.05n = 0.75       Equation 1

Number of coins:

He has p pennies.

The number of nickels is 3 more than the number of pennies.

Since the number of pennies is p, then the number of nickels is p + 3.

That gives us our second equation.

n = p + 3        Equation 2

System of equations:

Now we have a system of two equations in two unknowns:

0.01p + 0.05n = 0.75

n = p + 3

Since the second equation is already solved for n, we can use the substitution method.

Replace n in the first equation with p + 3.

0.01p + 0.05n = 0.75

0.01p + 0.05(p + 3) = 0.75

Distribute the 0.05

0.01p + 0.05p + 0.15 = 0.75

Combine like terms on the left side.

0.06p + 0.15 = 0.75

Subtract 0.15 from both sides.

0.06p = 0.6

Divide both sides by 0.06.

p = 0.6/0.06

p = 10

Now we substitute 10 for p in the second equation to find the value of n.

n = p + 3

n = 10 + 3

n = 13

He has 10 pennies and 13 nickels.

Check:

A) 13 - 10 = 3 He does have 3 more nickels than pennies.

B) $0.01(10) + $0.05(13) = $0.10 + $0.65 = $0.75

The number of coins and the value of the coins both check out, so our answer is correct.

It took them 4 days to install 480 chairs which means if they were working at a constant rate they got 120 chairs installed daily. with 360 chairs left that means in 3 days they will finish. so overall, it took the workers 7 days to finish, or a week.

Answer:

2/6 of it or 1/3 chance you get a 2 or 5

Step-by-step explanation:

Y=-1x+5

Slope intercept form is y=mx+b

m = slope

b = y intercept

As you can see from the line, the y-intercept if 5, so b is 5. To find the slope, we take two points, I'm using (0,5) and (2,3), and then divide change y by change in x or y2-y1 / x2-x1  

3-5   /  2-0

= -2/2= -1

The slope is -1, so m is -1.

y=-1x+5

Answer:

A. Randomization tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.

Step-by-step explanation:

---Researchers are investigating the effect of pH level in water on the breeding habits of the moon jellyfish. As part of a laboratory experiment, they will randomly assign one of three treatments, low pH, medium pH, or high pH, to the water in the tanks that hold the jellyfish.

Which of the following is the best reason for the random assignment of a treatment level to an experimental unit?

A. Randomization tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.

B. Randomization will make up for improper experimental design, data collection, and analysis.

C. Randomization makes the analysis easier since the data can be entered into the computer in any order.

D. Randomization is required by statistical consultants before they will analyze the experiment.

E. Randomization means that the experiment would not need to be replicated---

Randomization is used to ensure that the results of a trial or an experiment are actually because if the treatment or hypothesis we are trying, instead of any other external factor that we can not control, or because it just always happens that way, if all of the jellyfish are affected or not in the same way, then the Ph had little to nothing to do with it, and if only one group of them is affected we can re-try the experiment to see if the difference in the Ph had anything to do with the change.

Answer:

A.Randomization tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.

The equation (x + 5)² = 34 is equivalent to the polynomial in standard form x² + 10 · x = 9.

In this problem we find a polynomial that is in standard form but not a perfect square trinomial, that is, a polynomial that is not of the form:

(a · x + b)² = a² · x² + 2 · a · b · x + b²

The standard form of a polynomial is described by:

a · x² + b · x + c = 0

Where a, b, c are real coefficients.

But can transform part of the non-perfect polynomial by completing the square, that is, finding an equivalent expression of the form:

a · (x + r)² = c

This can be done by means of algebra properties:

x² + 10 · x = 9

x² + 10 · x + 25 = 34

(x + 5)² = 34

To determine that an item is not in an unordered array of 100 items, total numbers of values which have to linear search examine on average is 100. The correct answer is C.

Linear Search is described as a sequential search algorithm which starts at one end and goes through each element of a list until the needed element is found, otherwise the search continues till the end of the data set. This is the simplest searching algorithm.

Starting at the beginning of the data set, each item of data is examined until a match is made. Once the item is found, the search ends.

Hence, in this case, since there are 100 items, then there will be 100 numbers of values.

Answer:

5500 ml or 5.5 liters

Step-by-step explanation:

First, we should note that there are 1000 milliliters in 1 liter of liquid.

So, in milliliters, Peter filled three containers with 1500 ml, 750ml, and 2250 ml with 1000ml left over.

To find the total amount, we find the sum of all the milliliters:

1500 + 750 + 2250 + 1000 = 5500 ml

Again, we know that there are 1000 milliliters in 1 liter of liquid, so:

\(\frac{5500}{1000}\) = 5.5 liters

Answer:

The maximum profit the florist will earn from selling celebration bouquets is $725.

The florist will break-even after one-dollar decreases when her profit is zero. From the graph, this occurs at x = 10. So the florist will break-even after 10 one-dollar decreases.

The interval of the number of one-dollar decreases for which the florist makes a profit from celebration bouquets is (0, 10). This is because the profit is positive for values of x between 0 and 10, and becomes negative after 10.

Answer:

4.4 ounces/ 4 ounce (if rounded)

Step-by-step explanation:

There are 16 ounces in a pound, therefore the equation 12/16 will be useful since 16 ounces in a pound can be divided by 12, in conclusion 12/16=0.75 which is how much an ounce costs.

Then you will take $3.30 and divide it by 0.75 to get your answer for how many ounces you can buy for $3.30 which will equal 4.4 ounces but if you were to round it would be 4 ounces

Answer:

f(4) = 31

f(0) = 7

f(-1) = 1

Step-by-step explanation:

f(x) = 6x + 7

f(4) = 6(4) + 7

f(4) = 24 + 7

f(4) = 31

f(0) = 6(0) + 7

f(0) = 0 + 7

f(0) = 7

f(-1) = 6(-1) + 7

f(-1) = -6 + 7

f(-1) = 1

Answer: Everyone in your population must have an equal, non-zero chance of being selected. (In other words, everyone has an equal chance of receiving a survey.) You must know, specifically, what that chance of being selected is for each person.

Answer:

Let's first try to find the angle supplementary to measure 141°.

(Supplementary angles are two angles that add up together to equal 180°).

Set up an equation;

141 + x(unknown angle measure) = 180°

Solve for x:-

141 + x = 180

-141        -141

x = 39°.

Now that we've found one of the interior angles measure to this triangle, we will use this value to figure out the angle measure next to 'x'.

If we think of the line (highlighted in the picture I attached to this), extended, we can kind of make out of this line as a transversal cutting into the two parallel lines(L & M).

Furthermore, the measured angle 39°, is an alternate interior angle with the missing angle next to 'x'(highlighted with yellow in my picture).

And, alternate interior angles are congruent(meaning they measure the same degree).

Therefore, we can infer that the missing angle next to 'x' is also 39°.

Now that we've found one angle measure and another angle(given) next to x, we can see that angle x and those two angle measures (48° and 39°) combined are supplementary!

So now that we know that angles 48° and 39° are supplementary with x, we can find the value of x by finding it's supplement value!

Arrange an equation;

(48 + 39) + x = 180°

Simplify and solve for x:-

87 + x = 180

-87        -87

x = 93°, hence ∠X = 93°.
