Answer: :)

Step-by-step explanation:

Let's start by setting up a proportion to represent the ratio of black tiles to white tiles:

1 black tile : 4 white tiles

We know that Eddie wants a total of 25 tiles in the design, so we can set up another proportion to represent the ratio of white tiles to the total number of tiles:

white tiles : 25 total tiles

To solve for the number of white tiles, we need to find the equivalent ratio of white tiles in terms of the total number of tiles. We can do this by cross-multiplying our two proportions:

1 black tile * (white tiles/4 black tiles) = white tiles/4

white tiles/25 total tiles = (white tiles/4) / (1 black tile + white tiles/4)

Simplifying this expression, we get:

white tiles/25 = (white tiles/4) / (5/4)

white tiles/25 = (1/4) * (white tiles/5)

5 * white tiles = 100

white tiles = 20

Therefore, Eddie will use 20 white tiles in his design.

The inflation rate for that decade will be  34.39%. If the inflation rate had been the same for each year in that decade, the annual rate would have been 2.79%.

a) If the annual inflation rate was 3% for 10 years in a row, the inflation rate for that decade would be 34.39%. This is calculated by using the formula (1 + annual inflation rate)^number of years - 1. So in this case, it would be (1 + 0.03)^10 - 1 = 0.3439 or 34.39%.

b) To find the inflation rate for the decade from 1960 to 1970, we need to know the Consumer Price Index (CPI) for both years. The CPI for 1960 was 29.6 and the CPI for 1970 was 38.8.

We can use the formula (CPI in later year/CPI in earlier year)^(1/number of years) - 1 to find the annual inflation rate.

So in this case, it would be (38.8/29.6)^(1/10) - 1 = 0.0279 or 2.79%. Therefore, if the inflation rate had been the same for each year in that decade, the annual rate would have been 2.79%.

based on the line of best fit, we would predict that the day's high temperature would be approximately 34.29 degrees Fahrenheit or 1.272°C if Genesis sold 28 hot cocoas

The term "temperature" describes how hot or cold a body is. It is, specifically, a method of calculating the kinetic energy of the particles that make up an item. When particles move more quickly, the temperature rises, and vice versa.

Nearly every aspect of our daily lives and all scientific fields, from physics to geology, are significantly influenced by temperature.

The velocity of these particles likewise increases as the temperature rises.

A thermometer or a calorimeter is used to determine the temperature. In other words, a system's internal energy is determined by its temperature.

from the question...

We may infer from the scatter plot and the line of best fit that the line's equation is y = -0.7x + 52, where y stands for the volume of hot cocoa sold and x for the high temperature of the day in degrees Fahrenheit.

If Genesis sold 28 hot cocoas, we can solve for x and substitute y = 28 into the equation to determine the day's high temperature:

28 = -0.7x + 52

-0.7x = 28 - 52

-0.7x = -24

x = 34.29

So, if Genesis sold 28 hot cocoas, we would forecast that the day's high temperature would be roughly 34.29 degrees Fahrenheit based on the line of best fit.

The measures of angles 4 and 5 are:

∠5 = 104°

∠4 =76°

On the image we can see that angles 1 and 2 are next to eachother, that means that the sum of their measures must be a plane angle, that is an angle of 180°.

Then we can write the sum:

∠1 + ∠2 = 180°

(3x + 5) + (2x + 10) = 180

5x + 15 = 180

5x = 180 - 15

The events in terms of whether they are complimentary or not are:

The probability that it will not rain tomorrow is 2 / 3.

In probability theory, complementary events are two events that together cover all possible outcomes, meaning that if one event occurs, the other cannot occur. For example, in part (a) of the question, the events of getting an even number and getting an odd number when rolling a die are mutually exclusive, meaning that they cannot happen at the same time.

In part (b), the events of getting a prime number and getting an even number when rolling a die are not complementary events because the number 2 is both prime and even.

In parts (c) through (g), the events listed are complementary events. For example, in part (c), the events of all students attending class and no students attending class cover all possible outcomes, and only one of them can happen at a time.

(a) The proportion of observations in a standard normal distribution that satisfies z > -1.66 is 0.0475, or approximately 4.75%.

(b) The proportion of observations in a standard normal distribution that satisfies -1.66 < z < 1.66 is 0.9050, or approximately 90.50%.

A Z-score is a metric that quantifies how closely a value relates to the mean of a set of values.

Standard deviations from the mean are used to measure Z-score. A Z-score of zero means the data point's score is the same as the mean score.

To find the proportion of observations in a standard normal distribution that satisfies each of the statements, we need to use a standard normal distribution table or calculator.

(a) z > -1.66

We need to find the area to the right of z = -1.66 on a standard normal distribution table or calculator. This is equivalent to finding the area to the left of z = 1.66 since the standard normal distribution is symmetrical.

Using a standard normal distribution table or calculator, we find that the area to the left of z = 1.66 is 0.9525. Therefore, the area to the right of z = -1.66 is:

1 - 0.9525 = 0.0475

So, the proportion of observations in a standard normal distribution that satisfies z > -1.66 is 0.0475, or approximately 4.75%.

(b) -1.66 < z < 1.66

We need to find the area between z = -1.66 and z = 1.66 on a standard normal distribution table or calculator.

Using a standard normal distribution table or calculator, we find that the area to the left of z = 1.66 is 0.9525 and the area to the left of z = -1.66 is 0.0475 (as calculated in part (a)). Therefore, the area between z = -1.66 and z = 1.66 is:

0.9525 - 0.0475 = 0.9050

Therefore, the proportion of observations in a standard normal distribution that satisfies -1.66 < z < 1.66 is 0.9050, or approximately 90.50%.

The speed of the river's current is 3 miles per hour.

To determine the speed of the river's current, we can use the formula d = rt, where d is the distance, r is the rate, and t is the time.

We can set up two equations, one for upstream and one for downstream, and solve for the speed of the river's current.

For upstream:

9 = (6 - c)t

For downstream: 27 = (6 + c)t

Since it takes her the same amount of time to paddle 9 miles upstream as it does to travel 27 miles downstream, we can set the two equations equal to each other:

9 = (6 - c)t = 27 = (6 + c)t

Simplifying and solving for c:

9(6 + c) = 27(6 - c) 54 + 9c = 162 - 27c 36c = 108 c = 3

There are several methods that can be used to solve a quadratic equation. The most commonly used methods are:

1. Factoring
2. Completing the square
3. Quadratic formula
4. Graphing

Now, let's solve each equation using one of the methods listed above.

a. 2x^2 - 7x + 3 = 0

We can use the factoring method to solve this equation. First, we need to find two numbers that multiply to give us 3 and add to give us -7. The numbers are -3 and -1. So, we can factor the equation as follows:

(2x - 1)(x - 3) = 0

Now, we can set each factor equal to zero and solve for x:

2x - 1 = 0 => x = 1/2

x - 3 = 0 => x = 3

So, the solutions are x = 1/2 and x = 3.

b. x^2 + 10x + 1 = 0

We can use the quadratic formula to solve this equation. The quadratic formula is:

x = (-b ± √(b^2 - 4ac))/(2a)

Plugging in the values of a, b, and c, we get:

x = (-(10) ± √((10)^2 - 4(1)(1)))/(2(1))

Simplifying, we get:

x = (-10 ± √96)/2

So, the solutions are x = (-10 + √96)/2 and x = (-10 - √96)/2.

c. x² – 18=0

We can use the square root method to solve this equation. First, we need to isolate the x^2 term on one side of the equation:

x^2 = 18

Now, we can take the square root of both sides:

x = ±√18

Simplifying, we get:

x = ±3√2

the solutions are x = 3√2 and x = -3√2.

To find out how many of each type of coin Kevin and Randy Muise have, we can use a system of equations. Let's call the number of quarters "q" and the number of nickels "n". We can create two equations based on the information given:

q + n = 54 (the total number of coins)

0.25q + 0.05n = 11.10 (the total value of the coins)

Now we can use the substitution method to solve for one of the variables. Let's solve for "n" in the first equation:

n = 54 - q

Now we can substitute this value of "n" into the second equation:

0.25q + 0.05(54 - q) = 11.10

Simplifying and solving for "q":

0.25q + 2.7 - 0.05q = 11.10

0.20q = 8.40

q = 42

Now we can plug this value of "q" back into the first equation to find "n":

n = 54 - 42

n = 12

To find all the values of b that will make the trinomial 3x^(2)-bx+12 factorable, we need to use the discriminant of the quadratic formula. The discriminant is the part of the quadratic formula under the square root: b^(2)-4ac. If the discriminant is a perfect square, then the trinomial will be factorable.

So we plug in the values of a, b, and c from the trinomial: b^(2)-4(3)(12) = b^(2)-144.

We want this to be a perfect square, so we can set it equal to a perfect square and solve for b:

b^(2)-144 = 36

b^(2) = 180

b = sqrt(180)

b = 6sqrt(5)

So one value of b that will make the trinomial factorable is 6sqrt(5).

Now we can plug this value of b back into the trinomial and factor it:

3x^(2)-6sqrt(5)x+12 = 0

(3x-6)(x-sqrt(5)) = 0

So the factors of the trinomial are (3x-6) and (x-sqrt(5)).

The two supplementary angles where one angle measures 6° more than the other one are 87°  and 93°.

Two angles are said to be supplementary if the sum of the two angles is 180 degrees. One way to avoid confusion in these definitions is to note that s comes after c in the alphabet and 180 is greater than 90. 

Solution according to the information in the question:

Let, "x" be one of the two supplementary angles

then, the other angle will be "x+6" according to the question.

As we know sum of two supplementary angles is 180 degrees, so

x +(x+6)=180

⇒2x + 6 = 180

⇒2x = 180 - 6

⇒2x = 174

⇒x = 174/2

The measure of the angle being discussed is 84° and the measure of its supplementary angle is 96°. This is because the measure of the angle being discussed is 6° more than the measure of its supplementary angle.

A supplementary angle is two angles whose sum is 180 degrees. These angles do not have to be adjacent or even in the same plane, but their sum must always equal 180 degrees.

If the angle being discussed is 6° more than the measure of its supplementary angle, then the measure of the angle being discussed is 84° (180° - 6° = 84°). Therefore, the measure of the angle being discussed is 84° and the measure of its supplementary angle is 180° - 84° = 96°.

To further explain the relationship between the two angles, the supplementary angle is the measure of the angle that completes the 180° angle when combined with the angle being discussed. This means that the measure of the supplementary angle is the 180° minus the measure of the angle being discussed. In this case, the measure of the angle being discussed is 84° and thus, the measure of its supplementary angle is 180° - 84° = 96°.

  All zeros of polynomial functions  -3/2 , 5i and -5i

Zeros of polynomial are the points where the polynomial equals zero on the whole. In simple words, we can say that zeros of polynomial are values of the variable such that the polynomial equals 0 at that point. Zeros of a polynomial are also referred to as the roots of the equation and are often designated as α, β, γ respectively. Some of the methods used to find the zeros of polynomial are grouping, factorization, and using algebraic expressions.
