Answer:

40 7th Graders

Step-by-step explanation:

First you add all of the students to get 25. Then you divide 100 by 25 to get 4 (this is gonna be your multiplier) now multiply each part of the ration by 4, and you get 60 6th graders and 40 7th graders :D.

Step-by-step explanation:

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

Answer:

3x+y=2

Step-by-step explanation:

Just remember that standard form is expressed as Ax+By=C. I also attached a picture to prove that 3x+y=2 is the standard form equation that makes up the line.

Hope this helps and answers your question :)

Answer: B) -2.24

Step-by-step explanation:

Answer: it’s -2.24

Step-by-step explanation:

Because it’s already in decimal form and since it’s a negative decimals number it is -2.24

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

5. 0.66

6. 0.79

7. 5.2

8. 4.86

9. 4.3

10. 1.5

11. 5.84

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%

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.

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

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.
