Step 3 of 4: Using the two equations found in Step 2, enter the solution set using set notation.

Answer:

-60

Step-by-step explanation:

-15 = 1/3x + 5  Multiply all the way through by 3

-45 = x + 15  Subtract 15 from both sides of the equation

-60 = x

Answer: -60 = x

Step-by-step explanation:

If the output value is -15, we need to do this equation.

-15 = (1/3)x + 5.

-5                -5

-20 = (1/3)x

x3     x 3

-60 = x.

Now, let's double-check our answer.

f(60) = (1/3)(-60) + 5

f(-60) = -20 + 5

f(-60) = -15.

This means that x = -60 is our correct answer.

The number of outcomes, using the Fundamental Counting Theorem, is given as follows:

A. Red exactly 3 times and Purple exactly 2: 10.

B. Red at least ounce in 4 spins: 175.

C. Red at least ounce in 5 spins: 781.

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, obtained by the following formula, involving factorials.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

Item a is used with the combination formula, as it is an arrangement of five elements with 3 and 2 repetitions, hence the number of outcomes is:

[tex]C_{5,3} = \frac{5!}{3!2!} = 10[/tex]

The Fundamental Counting Principle states that if there are n independent trials, each with [tex]n_1, n_2, \cdots, n_n[/tex] possible results, the number of outcomes is calculated by the multiplication of the factorials as presented as follows:

[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]

For item b, in four spins, each with four outcomes, the parameters are given as follows:

[tex]n_1 = n_2 = n_3 = n_4 = 4[/tex]

Hence the number of outcomes is:

N = 4^4 = 256.

For no red results, the parameters are as follows:

[tex]n_1 = n_2 = n_3 = n_4 = 3[/tex]

Hence:

N = 3^4 = 81.

Hence the number of outcomes with at least one red is:

256 - 81 = 175.

For item 3, the lone difference is that there are five trials, hence:

The value of b after solution of the expression, b-14 = -10, is 4.

According to the question,

We have the following expression:

b-14 = -10

Now, we will first add 14 on both sides of the above equation:

b = -10+14

We know that when two integers are of different signs then the smaller number is subtracted from the larger number but the sign in the result is of the larger number.

So, in this case, 14 is larger than 10 then the result will be positive.

So, we have the following expression:

b = 4

Hence, the correct option is B.

Answer:

Q

Step-by-step explanation:

The probability of event A is 5/18.

The probability of event B is 29/36.

Probability is used to determine how likely it is that a random event would happen. The probability that the random event would happen would lie between 0 and 1.

The probability that the sum is greater than 8 = sample space that have a sum greater than 8 / total number of sample space

sample space that have a sum greater than 8 = (3,6) (4,5) (4,6) (5,4) (5,5) (5,6) (6,3) (6, 4) (6,5) (6,6) = 10

Total number of sample space = 36

The probability that the sum is greater than 8 = 10 / 36 = 5/18

The number of insects at t=0 is 700, the growth rate is 28e^0.04, population of insects after 10 days is 1044, and the graph of the function is attached.

What is function?

A function, according to a technical definition, is a relationship between a set of inputs and a set of potential outputs, where each input is connected to precisely one output.

a) Number of insects at time (t) = 0 days,

Putting t = 0 in given function:

P(t) = 700e^0.04(0) = 700e^0 = 700

Hence,  the number of insects at t = 0 days is 700.

b) Growth rate of insect population,

In order to find growth we need to differentiate the given function with respect to t.

So,  dP(t)/dt = 700(0.04)e^0.04(0)

= 28e^0.04

Hence, the growth rate is 28e^0.04.

c)  Graph the function is attached in the question.

d) The population of the insects after 10 days,

The probability that a red ticket is drawn first and then the second ticket drawn is blue is 0.253.

Probability determines the odds that a random event would occur. The odds that the random event occurs has a probability value that lies between 0 and 1.

The more likely it is that the event would occur, the closer the probability value would be to 1. The more unlikely it is that the event would not happen, the closer the probability value would be to 0.

The probability that a red ticket is drawn first and then the second ticket drawn is blue = (number of red tickets / total number of tickets) x (number of blue tickets / total number of tickets)

Total number of tickets = number of blue tickets + number of red tickets

Step-by-step explanation:

From inspection of the given diagram we can see that angle 1, angle 40° and a right angle are the interior angles of a right triangle.

As the interior angles of a triangle sum to 180°:

⇒ m∠1 + 40° + 90° = 180°

⇒ m∠1 + 130° = 180°

⇒ m∠1 + 130° - 130° = 180° - 130°

⇒ m∠1 = 50°

Therefore, the measure of angle 1 is 50°.

The compound interest = $5320  

and the total amount = $5832

In this question, we need to find the compound interest and the total amount after an hour if the interest is compounded every ten minutes.

Here, principal P= $512

rate of interest R = 5% per minute

                            = 5 x 10 (interest for every 10 min)

                             = 50

Now n = 60 / 10

        n = 6

So using compound interest formula the total amount would be,

A = P(1 + R / 100)^n

A = 512 (1 + 50/100)^6

A = 512 (3/2)^6

A = 5.2 (1.5)^6

A= $5832

Now the Compound Interest = A – P

                                                 = 5832 – 512

                                                 = $5320  

Therefore, the compound interest = $5320

Suppose a person gained three pounds (a negative weight loss). Then z = -1. This z-score tells you that x = -3 is 1 standard deviation to the left of the mean.

A z-score is a statistical measurement that describes a value's relationship to the mean of a group of values in terms of standard deviations. It is calculated using the formula:

[tex]\\\mathrm {z = \frac{x - \mu}{\sigma} }[/tex]

Where:

z = z-score

x = individual data point (in this case, the weight change in pounds)

μ = mean of the data set (average weight change in pounds)

σ = standard deviation of the data set (a measure of how spread out the data is)

If the person gained three pounds (a negative weight loss), it means the value of x is -3 pounds (x = -3).

To calculate the z-score, we need to know the mean and standard deviation of the weight changes in pounds for the entire group of people.

Let's assume the mean (μ) is 0 pounds (no weight change on average), and the standard deviation (σ) is 3 pounds (for example).

z = (-3 - 0) / 3

z = -1

So, the z-score (z) is -1.

A negative z-score indicates that the data point (in this case, the weight change of -3 pounds) is below the mean.

Since the z-score is -1, this tells us that the weight change of -3 pounds is 1 standard deviation to the left of the mean.

The negative sign indicates it is below the mean, and the absolute value of the z-score (1) indicates it is 1 standard deviation away from the mean.
