A recent report at a particular college said that 5476 students are taking math this semester, which represents 79% of the student population.
How many students attend this college?
Round answers to the nearest whole number as needed.

Answers

Answer 1

Answer: 6931

Step-by-step explanation:

79% of all students are taking math this semesters.  So there is an additional 21% of students not taking math.

5476/x = 79/100

cross multiply and divide to get the total number of students.

5476 x 100 = 547600

547600 divided by 79 = 6931  

check 5476 divided by 6931 = 79%  

Further proof of correct answer:

21% of 6931 = 1455

1455 + 5476 equals 6931, so the answer calculated is correct.

Jim's parents paid for the first three years of his college costs. When
he was a college senior, he was approved for an unsubsidized loan in the
amount of $15,200 at a 4.29% interest rate for 10 years.
a. If he chooses to make interest-only payments until the monthly loan
payments are due, for how long will he be making interest only
payments?

Answers

Jim can make interest-only payments until after 1 year and 6 months.

What is the interest-only payment?

The interest-only payment enables students to avoid interest capitalization during their school years and during the next six months after graduation.

The six-month period is called the grace period.

Non-capitalization of interest lowers the monthly repayments when payments become due after the grace period.

Amount of student loan = $15,200

Interest rate = 4.29%

Loan period = 10 years

Interest-only period = 1 year and 6 months

Amount of interest per month = $54.34 ($15,200 x 4.29% x 1/12)

Total interest during the interest-only period = $978.12 ($54.34 x 18)

Thus, the interest-only payments last for 18 months.

Determine the value of x. Use the Pythagorean Theorem. Show your work.

Answers

The value of x (hypotenuse) using the Pythagorean Theorem is 5 units.

What is Pythagorean Theorem?The Pythagorean Theorem states that the squares on the hypotenuse (the side across from the right angle) of a right triangle, or, in familiar algebraic notation, a² + b², are equal to the c² which is the hypotenuse.

So, the formula of the Pythagorean Theorem:

c² = a² + b²

Where a (AC) = 4 and b (CB) = 3 as the given figure is symmetric and so line CB will be equal to 3.

Now,

c² = a² + b²c² = 4² + 3²c² = 16 + 9c² = 25c = √25c = 5

Therefore, the value of x using the Pythagorean Theorem is 5 units.

The values of x for which curves cuts/touches the x - axis are the roots of that particular polynomial.

And that polynomial can be depicted in form :

[tex]\qquad \tt \rightarrow \: a(x - h1) (x - h2) (x - h3)........ (x - hn) = 0[/tex]

[ where, h1, h2, h3... hn represents roots of that polynomial, and " a " is the stretch of curve]

And by that, we can sort out the roots of given polynomial that are :

x = -3, -2, 1 and 2

Since there are four roots, the least degree polynomial formed will have bi - quadratic polynomial.

And it will be represented as :

[tex]\qquad \tt \rightarrow \: y=a(x - ( - 3)) (x - ( - 2))(x - 1)(x - 2) [/tex]

[tex]\qquad \tt \rightarrow \:y=a (x + 3)(x + 2)(x - 2)(x - 1) [/tex]

And it can be further solved to get ~

[tex]\qquad \tt \rightarrow \: y=a(x + 3)( {x}^{2} - 4)(x - 1)[/tex]

[tex]\qquad \tt \rightarrow \:y= a( {x}^{2} - 4)( {x}^{2} + 2x - 3)[/tex]

[tex]\qquad \tt \rightarrow \: y=a({x}^{4} + 2 {x}^{3} - 7{x }^{2} - 8x + 12)[/tex]

Now, it's time to evaluate the value of a, for that we can just use a point that satifys the curve ( i.e (0 , -2)

plug in the values :

[tex]\qquad\displaystyle \tt \rightarrow \: {-2= a(0⁴ +2(0)³-7(0)²-8(0) + 12 } [/tex]

[tex]\qquad\displaystyle \tt \rightarrow \: {-2= a(0 +0-0-0 + 12 } [/tex]

[tex]\qquad\displaystyle \tt \rightarrow \: {-2= a( 12 )} [/tex]

[tex]\qquad\displaystyle \tt \rightarrow \: {a= -2 ÷ 12 } [/tex]

[tex]\qquad\displaystyle \tt \rightarrow \: {a= -1/6} [/tex]

As part of your job you spend time each day contacting former customers. During one week, you contacted 15 people on Monday, 12 on Tuesday, 14 on Wednesday, 11 on Thursday, and 13 on Friday. What is the average number of customers contacted each day? Which averaging method did you use?

Answers

The average number of customers contacted each day is 13. We used the basic average method which is explained below.

The formula for calculating the average is:

Sum of all the observations ÷ Total number of observations

So, according to the formula

Sum of all the observations = People contacted on (Monday+ tuesday+wednesday+thursday+friday)

= 15+12+14+11+13

= 65

Number of observations = 5

So putting values in the formula, we get

65÷5

= 13

Hence, the average number of customers contacted is 13.

Answers

Using the binomial distribution, the probabilities are given as follows:

1) Three girls in a family of five children: 0.3125 = 31.25%.

2) At least two boys in a family of seven children: 0.9375 = 93.75%.

3) Total of 15 when four dice are thrown:  0.1080 = 10.80%.

4) At least two left-handed people in a group of 7: 0.1497 = 14.97%.

5) At least five of them have the same birth date: 0%.

What is the binomial distribution formula?

The formula for the probability of x successes is:

[tex]P(X = x) = C(n,x).p^{x}.(1-p)^{n-x}[/tex]

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

The parameters are given by:

n is the number of trials of the experiment.p is the probability of a success on a single trial of the experiment.

Item 1

A children is equally as likely to be a boy or a girl, hence the parameters are given as follows:

n = 5, p = 0.5.

The probability is P(X = 3), hence:

P(X = 3) = C(5, 3) x (0.5)³ x (0.5)² = 0.3125 = 31.25%.

Item 2

The parameters are:

n = 7, p = 0.5.

The probability of at least two boys is:

P(X >= 2) = 1 - P(X < 2).

In which:

P(X < 2) = P(X = 0) + P(X = 1).

Then:

P(X = 0) = (0.5)^7 = 0.0078.P(X = 1) = C(7,1) x (0.5)^7 = 0.0547.P(X < 2) = P(X = 0) + P(X = 1) = 0.0078 + 0.0547 = 0.0625.P(X >= 2) = 1 - P(X < 2) = 1 - 0.0625 = 0.9375 = 93.75%.

Item 3

This one is simple probability, number of desired outcomes divided by the number of total outcomes.

When 4 dice are thrown, we have that:

There are 140 outcomes with a sum of 15.There are 6^4 total outcomes.

Hence the probability is:

p = 140/(6^4) = 0.1080 = 10.80%.

Item 4

The parameters are:

n = 7, p = 0.1.

Hence, similarly to item 2:

P(X = 0) = (0.9)^7 = 0.4783.P(X = 1) = C(7,1) x (0.1) x (0.9)^6 = 0.3720.P(X < 2) = P(X = 0) + P(X = 1) = 0.4783 + 0.3720 = 0.8503.P(X >= 2) = 1 - P(X < 2) = 1 - 0.8503 = 0.1497 = 14.97%.

Item 5

The parameters are:

n = 75, p = 1/365 = 0.0027.

Then the probability is:

P(X >=5) = 1 - P(X < 5).

In which:

P(X < 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4).

Using a calculator, it is found that P(X < 5) = 1, hence the probability is of 0%, as P(X >=5) = 1 - 1 = 0.

x * 29.6% = 28600

x * 296/1000 = 28600

x * 296 = 28600 * 1000

The angle of elevation to the top of a building changes from 15​° to ​30° as an observer advances 140 feet toward the building. Find the height of the​ building, x, to the nearest foot.
pls explain

Answers

Answer:

70 ft

Step-by-step explanation:

To find the height of the building, we can use the trigonometric relationship between the angle of elevation, the distance from the object, and the height of the object.

In this case, we have a right triangle formed by the observer, the top of the building, and the base of the building. Therefore, we can use the tangent trigonometric ratio, since the height of the building is the opposite the angle of elevation, and the distance between the observer and the building is the side adjacent the angle.

[tex]\boxed{\begin{minipage}{7 cm}\underline{Tangent trigonometric ratio} \\\\$\sf \tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle.\\\end{minipage}}[/tex]

Let "x" be the height of the building.

Let "d" be the initial distance from the observer to the building.

The angle of elevation changes from 15° to 30° as the observer advances 140 feet toward the building.

(See the attachment for a visual representation).

Based on this information, we can set up the following equations:

[tex]\tan 15^{\circ}=\dfrac{x}{d}[/tex]

[tex]\tan 30^{\circ}=\dfrac{x}{d-140}[/tex]

Rearrange both equations to isolate d:

[tex]d=\dfrac{x}{\tan 15^{\circ}}[/tex]

[tex]d=\dfrac{x}{\tan 30^{\circ}}+140[/tex]

Solve this system of equations by the method of substitution.

[tex]\dfrac{x}{\tan 15^{\circ}}=\dfrac{x}{\tan 30^{\circ}}+140[/tex]

[tex]\dfrac{x}{\tan 15^{\circ}}-\dfrac{x}{\tan 30^{\circ}}=140[/tex]

[tex]\dfrac{x\tan 30^{\circ}-x \tan 15^{\circ}}{\tan 30^{\circ}\tan 15^{\circ}}=140[/tex]

[tex]\dfrac{x(\tan 30^{\circ}- \tan 15^{\circ})}{\tan 30^{\circ}\tan 15^{\circ}}=140[/tex]

[tex]x=\dfrac{140\tan 30^{\circ}\tan 15^{\circ}}{\tan 30^{\circ}- \tan 15^{\circ}}[/tex]

[tex]x=\dfrac{140\cdot \frac{\sqrt{3}}{3}(2-\sqrt{3})}{\frac{\sqrt{3}}{3}- (2-\sqrt{3})}[/tex]

[tex]x=\dfrac{\dfrac{140(2\sqrt{3}-3)}{3}}{\dfrac{4\sqrt{3}-6}{3}}[/tex]

[tex]x=\dfrac{140(2\sqrt{3}-3)}{2(2\sqrt{3}-3)}[/tex]

[tex]x=\dfrac{140}{2}[/tex]

[tex]x=70[/tex]

Therefore, the height of the building is exactly 70 feet.

Find the distance between the points (−1,0) and (7,6).

Answers

The distance between the point (-1,0) and (7,6) is 10.

Distance between the points:

Distance between two points is the length of the line segment that connects the two points in a plane.

The formula to find the distance between the two points is usually given by

d=√((x2 – x1)² + (y2 – y1)²).

Given,

(−1,0) and (7,6).

Here we need to find the distance between these points.

Apply the values on the formula , in order to solve it,

d = √(7 - (-1))² + (6 - 0)²

When we simplify it, then we get,

d = √(7 + 1)² + (6)²

d = √(8)² + 36

d = √64 + 36

d = √100

d = 10

Therefore, the distance is 10.

The length of the unknown side of the triangle using similar triangle ratio concept is; x = 24

How to Solve similar triangles?

We want to find the length of the unknown side of the similar triangles.

Similar triangles are defined as triangles that have the same shape, but their sizes may vary. All equilateral triangles, squares of any side lengths are examples of similar objects. Thus, we can say that if two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion.

From the given triangle ADE which is divide into a similar triangle ABC with an unknown side x, we can use the concept of similar triangle ratios to get the unknown value of x as;

6/x = 8/(x + 8)

Cross multiply to get;

6(x + 8) = 8x

6x + 48 = 8x

8x - 6x = 48

2x = 48

x = 48/2

x = 24
