Explanation:

The total number of students is

[tex]n(S)=35[/tex]

Concept:

To figure out the probability that a student earns grade A,B or C

Will be calculated below as

[tex]P(A,BorC)=P(A)+P(B)+P(C)[/tex]

The Probability of A is

[tex]P(A)=\frac{n(A)}{n(S)}=\frac{5}{35}[/tex]

The probabaility of B is

[tex]P(B)=\frac{n(B)}{n(S)}=\frac{10}{35}[/tex]

The probabaility of C is

[tex]P(B)=\frac{n(B)}{n(S)}=\frac{15}{35}[/tex]

Hence,

By substituting the values in the concept, we will have

[tex]\begin{gathered} P(A,BorC)=P(A)+P(B)+P(C) \\ P(A,BorC)=\frac{5}{35}+\frac{10}{35}+\frac{15}{35}=\frac{30}{35} \\ P(A,BorC)=0.857 \\ P(A,BorC)\approx0.86(nearest\text{ }hundredth) \end{gathered}[/tex]

A certain species of deer is to be introduced into a forest, and wildlife experts estimate the population will grow to P(t) = (944)3 t/3, where t represents the number ofyears from the time of introduction.What is the tripling-time for this population of deer?

Answers

Ok, so

Here we have the function:

[tex]P(t)=944(3)^{\frac{t}{3}}[/tex]

Now we want to find the tripling-time for this population of deer.

If we make t=0, we will find the initial population of deer. This is:

[tex]P(0)=944(3)^{\frac{0}{3}}=944[/tex]

Now, we want to find the time "t" such that this population is the triple.

This is:

[tex]\begin{gathered} 944(3)=944(3)^{\frac{t}{3}} \\ 2832=944(3)^{\frac{t}{3}} \\ \frac{2832}{944}=3^{\frac{t}{3}} \\ 3=3^{\frac{t}{3}} \end{gathered}[/tex]

We got this exponential equation:

[tex]3=3^{\frac{t}{3}}[/tex]

As the base is the same, we could equal the exponents:

[tex]\begin{gathered} 1=\frac{t}{3} \\ t=3 \end{gathered}[/tex]

Therefore, tripling-time for this population of deer are 3 years.

Of the total amount paid, what percentage is paid toward the principal and what percentage is paid for interest?The percentage paid toward the principal is _____% and the percentage paid for interest is ____%.(Round to the nearest tenth as needed.)

Answers

a) The amount borrowed is $67,000 the annual interest rate is 3%, the number of payments per year is 12, the loan term is 22 years, and the payment amount is $347

b) There are 12 payments per year for 22 years; multiply 12 by 22 to get the total number of payments:

[tex]12\times22=264[/tex]

To find the total amount paid, multiply the number of payments by the payment amount:

[tex]264\times347=91,608[/tex]

There are 264 payments toward the loan and the total amount paid is $91,608

c) Toward principal: $67,000

Toward interest: subtract the principal from the payment amount:

The maintenance department at the main campus of a large state university receives daily requests to replace fluorescent lightbulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 37 and a standard deviation of 10. iS Using the 68-95-99.7 rule, what is the approximate percentage of lightbulb replacement requests numbering between 37 and 67?

Answers

Answer: 49.85%

Explanation:

From the information given,

mean = 37

standard deviation = 10

The 68-95-99.7 rule states that 68% of the data fall within 1 standard deviation of the mean. 95% of the data fall within 2 standard deviations of the mean and 99.7% of the data fall within 3 standard deviations of the mean. Thus,

1 standard deviation to the left of the mean = 37 - 10 = 27

1 standard deviation to the right of the mean = 37 + 10 = 47

3 standard deviation to the left of the mean = 37 - 3(10) = 37 - 30 = 7

3 standard deviations to the right of the mean = 37 + 3(10) = 37 + 30 = 67

We can see that the percentage of lightbulb replacement requests numbering between 37 and 67 falls within 3 standard deviations to the right of the mean. This is just half of the area covered by 99.7%. Thus

The percentage of lightbulb replacement requests numbering between 37 and 67

= 99.7/2 = 49.85%

2. Multiply both sides by 2

[tex]\begin{gathered} \frac{E}{m}\times2=\frac{1}{2}v^2\times2 \\ 2\frac{E}{m}=\frac{2}{2}v^2 \\ 2\frac{E}{m}=v^2 \end{gathered}[/tex]

3. in order to get rid of the exponent of v, take the square root on both sides

According to the information given in the exercise:

- Group A contains a total of 155 people.

- One-fifth of that people will be selected to win $20 fuel cards.

- The total number of people in Group B is 686.

Then, you can determine that the number of people that will be selected to win $20 fuel cards is:

By applying Kepler's third law of planetary motion, the approximate revolution time for Jupiter is equal to 12 years.

What is Kepler's third law?

Mathematically, Kepler's third law of planetary motion is given by this mathematical expression:

T² = a³

Where:

T represents the orbital period.a represents the semi-major axis.

Note: Earth has 1 astronomical unit (AU) in 1 year of time.

For this direct variation, the value of the constant of proportionality (k) is given by:

T² = ka³

k = T²/a³

k = 1²/1³

k = 1.

When the semi-major axis or the distance of Jupiter from Sun is 5.2, we have;

T² = ka³

T² = 1 × 5.2³

T² = 140.608

The instructions are: Write,evaluate,graph on a Number Line the following inequalities:Six increased by twice a number is no more than 20.

Answers

• Given the description "Six increased by twice a number is no more than 20", you need to know the following:

- In this case, the word "increased" indicates an Addition.

- The word "twice" indicates a Multiplication by 2.

- "No more than" indicates that six increased by twice a number must be less than or equal to 20.

- The inequality symbol whose meaning is "Less than or equal to" is:

[tex]\leq[/tex]

Knowing the information shown before, you can write the following expression to represent "Six increased by twice a number" (Let be "x" the unknown number):

[tex]6+2x[/tex]

Therefore, you can write the following inequality that models the description given in the exercise:

[tex]6+2x\leq20[/tex]

• Now you need to solve it:

1. Apply the Subtraction Property of Inequality by subtracting 6 from both sides of the inequality:

[tex]\begin{gathered} 6+2x-(6)\leq20-(6) \\ \\ 2x\leq14 \end{gathered}[/tex]

2. Apply the Division Property of Inequality by dividing both sides of the inequality by 2:

[tex]\begin{gathered} \frac{2x}{2}\leq\frac{14}{2} \\ \\ x\leq7 \end{gathered}[/tex]

• In order to graph the solution on a Number Line, you can follow these steps:

- Since the inequality symbol indicates that "x" is less than 7, it indicates that 7 is included in the solution. Therefore, you must draw a closed circle over that value.

- Draw a line from the circle to the left.

Then, you get:

Hence, the answer is:

Then we have:

[tex]ax^3+(4a+b)x^2+(4b+c)x+4c=2x^3+9x^2+3x-4[/tex]

Two polynomials are equal if and only if their coefficients are equal, this leads to the following equations:

[tex]\begin{gathered} a=2 \\ 4a+b=9 \\ 4b+c=3 \\ 4c=-4 \end{gathered}[/tex]

From the first one it is clear that the value of a is 2, from the last one we have:

[tex]A_{\text{figure}}=2A_{\text{trapezoid}}+2A_{\text{triangle}}[/tex]

The area of a trapezoid is given by the formula:

[tex]\begin{gathered} A_{\text{trapezoid}}=\frac{1}{2}(a+b)h \\ \text{where a and b are opposite sides of the trapezoid} \\ h\text{ is the height} \end{gathered}[/tex]

Thus, we have:

[tex]\begin{gathered} A_{\text{trapezoid}}=\frac{1}{2}(1\frac{1}{2}+3)2 \\ A_{\text{trapezoid}}=\frac{1}{2}(1.5+3)2 \\ A_{\text{trapezoid}}=\frac{1}{2}\times4.5\times2=4.5m^2 \end{gathered}[/tex]

Area of a triangle is given by the formula:

[tex]A_{\text{triangle}}=\frac{1}{2}\times base\times height[/tex]

Thus, we have:

[tex]\begin{gathered} A_{\text{triangle}}=\frac{1}{2}\times2\times1\frac{1}{2} \\ A_{\text{triangle}}=\frac{1}{2}\times2\times1.5=1.5m^2 \end{gathered}[/tex]

Hence, the area of the company's sign is:

[tex]\begin{gathered} A=(2\times4.5)+(2\times1.5) \\ A=9+3=12m^2 \end{gathered}[/tex]

A typical soda can has a diameter of 5.3 centimeters and height of 12 centimeters. How many square centimeters of aluminum is needed to make the can? My answer is 244. I am confused how I got the answer.

Answers

The can is made up of aluminium.

So the area of the can must be equal to the area of the Aluminium sheet.

The can is in the form of a cylinder with diameter (d) 5.3 cm, and height (h) 12 cm.

Then its area is calculated as,

[tex]\begin{gathered} A=\pi d(\frac{d}{2}+h) \\ A=\pi(5.3)(\frac{5.3}{2}+12) \\ A=243.9289 \\ A\approx244 \end{gathered}[/tex]

Thus, the area of the Aluminium sheet required is 244 square centimeters.

Kindly help by providing answers to these questions.
