Suppose that grade point averages of undergraduate students at one university have a bell-shaped distribution with a mean of 2.61 and a standard deviation of 0.4. Using the empirical rule, what percentage of the students have grade point averages that are between 2.21 and 3.01?

Answers

Answer:

68%

Step-by-step explanation:

We start by calculating the z-scores of both

z-score = (x-mean)/SD

for 2.21

z-score = (2.21-2.61)/0.4 = -1

For 3.01

z-score = (3.01-2.61)/0.4 = 0.4/0.4 = 1

So what we want to find is the percentage between -1 SD and 1 SD of the mean

This is the percentage corresponding to the probability

P(-1 < x < 1)

According to the empirical rule, this is a value of;

68.269%

Answers

Answer:

-15

Step-by-step explanation:

() means to multiply

So, -3(5) = -3 x 5 = -15

Answer: -15

The question asks you to find the "product," which means the result of multiplying. Both the word "product" and the parentheses indicate that you have to multiply.

Since it's a negative (-) multiplied by a positive (+), your product will be negative (-).

So, -3(5) = -15.

A triangle has ∠1 and ∠2 as remote interior angles with respect to exterior angle ∠3. Given that m∠1 = 50 and m∠2 = 70, Alicia reasoned that m∠3 must be 60. Is Alicia correct? If not, explain Alicia's error.

Answers

Answer:

No, 60 is the third interior angle's mesure, not the exterior ∠3.

Step-by-step explanation:

Say that ∠1=∠A=50 and ∠2=∠B=70. The remote interior angles are the angles that are not touvhing the exterior angle. So ∠3 would be the the exterior angle to ∠C. ∠C=60 as the sum of the interior angles is 180.

The exterior angle is the angle formed by extending one of the triangle's sides. A straight line has the angle 180, so∠3=180-∠C=180-60=120.

Solution:

We can see that each term when subtracted by 4, gives the next term.

This means that:

n₁ - 4(2) + 4(1) = n₂

Let's substitute the values to check:

=> n₁ - 4(2) + 4(1) = n₂ => n₁ - 8 + 4 = n₂ => n₁ - 4 = n₂ => 18 - 4 = 14=> 14 = 14 (Proved)

Now, we can find the nth term aₙ by using the formula:

18 - 4(nth term) + 4(1) = Value of nth term

To check that the formula is correct, let's substitute the value of nth as the fifth term of the sequence.

18 - 4(nth term) + 4(1) = Value of nth term=> 18 - 4(5) + 4(1) = Value of 5th term=> 18 - 4(5) + 4(1) = Value of 5th term=> 18 - 20 + 4 = Value of 5th term=> 18 - 16 = Value of 5th term=> 2 = Value of 5th term

Now, let's find the fifth term mentally. Keep subtracting 4 until you reach the fifth term.

=> 18 - 4 = Second term of sequence=> 14 = Second term of sequence=> 14 - 4 = Third term of sequence=> 10 = Third term of sequence=> 10 - 4 = Fourth term of sequence=> 6 = Fourth term of sequence=> 6 - 4 = Fifth term of sequence=> 2 = Fifth term of sequence

We are getting the same result from both ways.

In conclusion, our formula to find the nth term is "18 - 4(nth term) + 4(1)".

Suppose that the flying hours for aircraft operated by regional airlines in the U.S. during 2006 are normally distributed with mean 2500 and standard deviation 400. Find the number of flying hours such that about 97.5% of the aircraft has flying hours exceeding this number.
A) 1,700
B) 2,100
C) 2.500
D) 2,900
E) 3,300

Answers

Answer:

Step-by-step explanation:

Given that :

Mean (μ) = 2500

Standard deviation (σ) = 400

P = 97.5% = 0.975

Zscore corresponding to p(z > x) = 0.975

Z = - 1.96 ( Z probability calculator)

Using the relation :

Zscore = (score (x) - μ) / σ

-1.96 = (x - 2500) / 400

x - 2500 = 400 * - 1.96

x - 2500 = - 784

x = - 784 + 2500

x = 1716

Hence, number of flying hours required is 1716

The average starting salary for this year's graduates of a large community college is $30,000 with a standard deviation of $8,000. Furthermore, it is known that the starting salaries are normally distributed. a. What is the probability that a randomly selected LU graduate will have a starting salary of at least $30,400? b. Individuals with starting salaries of less than $15,600 receive a low income tax break. What percentage of the graduates will receive the tax break? c. what are the minimum and the maximum starting salaries of the middle 95% of the LU graduates? d. If 303 of the recent graduates have salaries of at least $43,120, how many students graduated this year from this university?

Answers

Answer:

0.048 ; 0.03593 ; (14320, 45680) ; 6000

Step-by-step explanation:

Given a normal distribution :

Mean salary (m) = $30000

Standard deviation (s) = $8000

A.) probability of having a starting salary of atleast 30400

P(x ≥ 30400)

Obtain the standardized value (Z) :

Z = (x - m) / s

Z = (30400 - 30000) / 8000

Z = 400 / 8000 = 0.05

P(Z ≥ 0.05) = 0.48006 (Z probability calculator)

b. Individuals with starting salaries of less than $15,600 receive a low income tax break. What percentage of the graduates will receive the tax break?

P(X < 15600)

Obtain the standardized value (Z) :

Z = (x - m) / s

Z = (15600 - 30000) / 8000

Z = - 14400 / 8000 = - 1.8

P(Z < - 1.8) = 0.03593

c. what are the minimum and the maximum starting salaries of the middle 95% of the LU graduates?

Zscore which corresponds to 0.95 is 1.96

Minimum:

-1.96 = (x - 30000) / 8000

-15680 = x - 30000

x = 14320

Maximum :

1.96 = (x - 30000) / 8000

15680 = x - 30000

x = 45680

d. If 303 of the recent graduates have salaries of at least $43,120, how many students graduated this year from this university?

P(X ≥ 43120)

Z = (43120 - 30000) / 8000

Z = 13120 / 8000

Z = 1.64

P(Z ≥ 1.64) = 0.050503

Hence,

0.050503 = 303

1 = x

x = 303 / 0.05050

= 6000

A farmer wants to build a rectangular pen which will be bounded on one side by a river and on the other three sides by a single-strand electric fence. If the farmer has 40 meters of wire to use, what is the largest area that the farmer can enclose?

Answers

Answer:

A) Dimensions;

Length = 20 m and width = 10 m

B) A_max = 200 m²

Step-by-step explanation:

Let x and y represent width and length respectively.

He has 40 metres to use and he wants to enclose 3 sides.

Thus;

2x + y = 40 - - - - (eq 1)

Area of a rectangle = length x width

Thus;

A = xy - - - (eq 2)

From equation 1;

Y = 40 - 2x

Plugging this for y in eq 2;

A = x(40 - 2x)

A = 40x - 2x²

The parabola opens downwards and so the x-value of the maximum point is;

x = -b/2a

Thus;

x = -40/2(-2)

x = 10 m

Put 10 for x in eq 1 to get;

2(10) + y = 40

20 + y = 40

y = 40 - 20

y = 20m

Thus, maximum area is;

A_max = 10 × 20

A_max = 200 m²

The area of the pen is the product of its dimensions

The largest area the farmer can enclose is 200 square meters

The perimeter of the pen is given as:

[tex]\mathbf{P = 40}[/tex]

Because one side of the fence is covered by a river, the perimeter would be:

[tex]\mathbf{2x + y = 40}[/tex]

Make y the subject

[tex]\mathbf{y = 40 - 2x}[/tex]

The area of the pen is:

[tex]\mathbf{A = xy}[/tex]

Substitute [tex]\mathbf{y = 40 - 2x}[/tex]

[tex]\mathbf{A = x(40 - 2x)}[/tex]

Expand

[tex]\mathbf{A = 40x - 2x^2}[/tex]

Differentiate

[tex]\mathbf{A' = 40 - 4x}[/tex]

Set to 0

[tex]\mathbf{ 40 - 4x = 0}[/tex]

Rewrite as:

[tex]\mathbf{ 4x = 40}[/tex]

Divide through by 4

[tex]\mathbf{x = 10}[/tex]

Substitute 10 for x in [tex]\mathbf{A = x(40 - 2x)}[/tex]

[tex]\mathbf{A = 10 \times (40 - 2(10))}[/tex]

[tex]\mathbf{A = 200}[/tex]

Hence, the largest area the farmer can enclose is 200 square meters
