1. Daily earnings of an amusement park before any 2$ increases

2. Number of tickets sold after x increases of 2$

Hopefully this helps!

The answers are daily earnings of the amusement park before any $2 increases and the number of tickets sold after x increases of $2.

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

\(\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n\)

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have:

An amusement park prices tickets at $55 and sells an average of 500 tickets daily.

From the question, we have a polynomial that represents the daily earnings of the amusement park.

P(x) = -40x² - 100x + 27,500

The constant of the polynomial expression represents the daily earnings of the amusement park before any $2 increases.

And (500 - 20x) represents the number of tickets sold after x increases of $2

Thus, the answers are daily earnings of the amusement park before any $2 increases and the number of tickets sold after x increases of $2.

The pairs of triangles can be proven similar through SSS similarity is given by Third pair.

We know that the SSS similarity criteria will have the ratio of three corresponding sides of both triangles congruent.

The variance of the four employees' salaries is 5.1, meaning that the difference in their salaries is 5.1 thousand dollars.

Step 1: Find the mean of the four salaries

33 + 31 + 24 + 36 = 124

124 ÷ 4 = 31

Mean = 31

Step 2: Find the difference between each salary and the mean

33 - 31 = 2

31 - 31 = 0

24 - 31 = -7

36 - 31 = 5

Step 3: Square each of the differences

2² = 4

0² = 0

(-7)² = 49

5² = 25

Step 4: Add up the squared differences

4 + 0 + 49 + 25 = 78

Step 5: Divide the sum by the number of salaries (minus 1)

Answer:

(-√6+√2)/4

Step-by-step explanation:

we'll use the addition identity of cos which is cos(a+b)=cos(a)*cos(b)+sin(a)*sin(b)

and the numbers we'll use are 180 and 75 since they add up to make 255 and they have some fixed values so we'll add them up

cos(75+180)= cos(75)*cos(180)+sin(75)*sin(180)

and the answer we get is (\(-\sqrt{6} +\sqrt{2}\))/4

basically, just write this in fraction form without the brackets (the 4 is dividing both of them so write it in the middle)

I hope I get this write as this is the first time I'm solving questions like these

and one thing to remember is that for cosine try to use numbers under 180 or 180 itself as the range of the cosine function is from -180 to 180 so even if we use like 181 it goes into negative and decimal similarly for sine its -90 to 90

The ratio of 75:125 is 3:5.

The ratio 3 mm : 3000 mm is 1:1000.

The ratio of 7500g:2 Kg is 3.75:1.

The ratio of 250ml:2l is 1:8.

To simplify this ratio, we need to find the greatest common factor (GCF) of 75 and 125, and divide both terms by it.

The factors of 75 are: 1, 3, 5, 15, 25, 75.

The factors of 125 are: 1, 5, 25, 125.

The GCF is 25.

Dividing both terms by 25, we get:

75 ÷ 25 = 3

125 ÷ 25 = 5

Therefore, the simplified ratio is 3:5.

1.1.2. 3mm:3m

To simplify this ratio, we need to convert the units so that they are the same.

1 m = 1000 mm

So, 3 m = 3000 mm

Now, the ratio is 3 mm : 3000 mm.

We can simplify this ratio by dividing both terms by 3:

3 mm ÷ 3 = 1 mm

3000 mm ÷ 3 = 1000 mm

Therefore, the simplified ratio is 1:1000.

1.1.3. 7500g:2 Kg

To simplify this ratio, we need to convert either grams to kilograms or kilograms to grams so that both terms have the same unit.

7500 g = 7.5 kg (since 1 kg = 1000 g)

Now, the ratio is 7.5 kg : 2 kg.

We can simplify this ratio by dividing both terms by 2:

7.5 kg ÷ 2 = 3.75 kg

2 kg ÷ 2 = 1 kg

Therefore, the simplified ratio is 3.75:1.

1.1.4. 250ml:21

To simplify this ratio, we need to convert milliliters to a whole number.

We can convert 250 ml to 250/21 ml by dividing both terms by 21:

250 ml ÷ 21 = 11.9 ml (rounded to one decimal place)

Now, the ratio is 11.9 ml : 21.

We can simplify this ratio by dividing both terms by 0.1:

11.9 ml ÷ 0.1 = 119 ml

21 ÷ 0.1 = 210

Therefore, the simplified ratio is 119:210.

1.1.5. 250 kg:2 tonnes

To simplify this ratio, we need to convert either kilograms to tonnes or tonnes to kilograms so that both terms have the same unit.

1 tonne = 1000 kg

So, 2 tonnes = 2000 kg

Now, the ratio is 250 kg : 2000 kg.

We can simplify this ratio by dividing both terms by 250:

250 kg ÷ 250 = 1 kg

2000 kg ÷ 250 = 8 kg

Therefore, the simplified ratio is 1:8.

Answer:

y = - \(\frac{1}{3}\) x + 7

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 3 ← is in slope- intercept form

with slope m = 3

given a line with slope m then the slope of a line perpendicular to it is

\(m_{perpendicular}\) = - \(\frac{1}{m}\) = - \(\frac{1}{3}\) , then

y = - \(\frac{1}{3}\) x + c ← is the partial equation

to find c substitute (- 6, 9 ) into the partial equation

9 = - \(\frac{1}{3}\) (-6) + c = 2 + c ( subtract 2 from both sides )

7 = c

y = - \(\frac{1}{3}\) x + 7 ← equation of perpendicular line

Answer:

1821 mL or 1.821 L

Step-by-step explanation:

Converting L to mL :

Unit rate : 1 L = 1000 mL

⇒ 2L = 2000 mL

Now three amounts of 57 mL, 69 mL, and 53 mL are used. They need to be subtracted from the total.

⇒ Remaining = 2000 - [57 + 69 + 53]

⇒ Remaining = 2000 - 179

⇒ Remaining = 1821 mL or 1.821 L

The expression 1 2/5 + 2 2/3 using fifteenths is 3 + 6/15 + 10/15

From the question, we have the following parameters that can be used in our computation:

1 2/5 + 2 2/3

3 + 2/5 + 2/3

To rewrite the expression using fifteenths, we multiply the numerator and the denominator of the fractions by the same number

In this case, we use 3 and 5

So, we have

3 + 2/5 * 3/3 + 2/3 * 5/5

Evaluate the products

3 + 6/15 + 10/15

Hence, the expression using fifteenths is 3 + 6/15 + 10/15

The probability that an antigen test comes back positive is approximately 0.05225, or about 5.225%.

We have,

To find the probability that an antigen test comes back positive, we need to consider both the true positive rate (probability of a positive test given that the person is infected) and the false positive rate.

Now,

Prevalence of coronavirus in California: 3 out of 1000

False positive rate of the antigen test: 0.05 (5 out of 100)

Let's calculate the probability of a positive test result.

The true positive rate can be calculated as 1 minus the false negative rate (probability of a negative test given that the person is infected):

True positive rate = 1 - 0.2 = 0.8 (or 80 out of 100)

The probability of a positive test result can be calculated using Bayes' theorem:

P(Positive test) = P(Positive test | Infected) x P(Infected) + P(Positive test | Not Infected) x P(Not Infected)

P(Positive test) = (0.8 x 3/1000) + (0.05 x 997/1000)

P(Positive test) = 0.0024 + 0.04985

P(Positive test) = 0.05225

Therefore,

The probability that an antigen test comes back positive is approximately 0.05225, or about 5.225%.

The lowest price per pair of socks will be 8 pairs for $8.99 among the given options thus, option (B) is correct.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Division = divide any two numbers or variables called division.

For example 4/8

As per the given,

Cost per pair of 12 pairs for $15.99 ⇒ 15.99/12 = $1.33

Cost per pair of 8 pairs for $8.99 ⇒ 8.99/8 = $1.12

Cost per pair of 4 pairs for $4.99 ⇒ 4.99/4 = $1.24

Cost per pair of 6 pairs for $7.99 ⇒ 7.99/6 = $1.33

Since $1.12 is the lowest among all thus, 8 pairs for $8.99 will be the lowest.

Hence "The lowest price per pair of socks will be 8 pairs for $8.99".

Absolute value is the distance of a number from zero. Since distance is always positive, the absolute value is the same number but positive.

Please note, for this problem I have rounded to 5 decimal points because the answer is irrational.

Subtracting

There are 2 different ways to approach this problem. You can either estimate the square root of 5 or plug this question straight into a calculator.

First, we can estimate \(\sqrt{5}\) and round to 5 decimal places.

Then, take this value and subtract.

Absolute Value

Now that we have solved the subtraction problem we have to find the absolute value. As stated above, the easiest way to find absolute value is to simply make the number positive. Since the answer is already positive, this is the final answer.
