(–18, 12)
(18, 0)

Answer:

39.10%

Step-by-step explanation:

The given timeout distributions are:

Exp (1/10), Exp (1/12)

The equation to use is the following:

F (x) = 1 - e ^ (- a / b); x> 0

So the probability is:

P (food has not arrived after waiting 25 minutes | R) = e ^ (- 10/10) = 0.3679

P (food has not arrived after waiting 25 minutes | S) = e ^ (- 12/15) = 0.2865

So:

P (food has not arrived after waiting 25 minutes) = (food has not arrived after waiting 25 minutes | R) * P (R) + (food has not arrived after waiting 25 minutes | S) * P (S)

Replacing:

P (food has not arrived after waiting 25 minutes) = 0.3679 * 1/3 + 0.2865 * 2/3 = 0.3136

However:

P (R | food has not arrived after waiting 25 minutes) = (food has not arrived after waiting 25 minutes | R) * P (R) / P (food has not arrived after waiting 25 minutes)

P (R | food has not arrived after waiting 25 minutes) = 0.3679 * 1/3 / 0.3136 = 0.3910

It means that the probability is 39.10%

Answer: 16/25

Step-by-step explanation:

Answer:

The answer is 16/25

Step-by-step explanation:

Since the original scale factor was 4/5 then you would need to square four and five in order to get the new scale factor.

When you square 4 you get 16 and when you square 5 you get 25. Therefore the answer should be 16/25.

Answer:

5.18 pounds per square inch

Complete question:

If the pressure is 6 pounds per square inch when the temperature is 440° F,find  the pressure exerted when the temperature of the gas is 380°F.

Step-by-step explanation:

According to the Gay Lussac's Law:

[tex]\frac{P_1}{T_1} =\frac{P_2}{T_2}[/tex]

where, P and T are the pressure and temperature of an enclosed ideal gas.

Given:

Initial pressure [tex]P_1[/tex] = 6 pounds per square inch

Initial Temperature [tex]T_1[/tex]=440° F

Final Temperature [tex]T_2[/tex]=380° F

Final Pressure [tex]P_2[/tex]=?

Substituting all values in the formula

[tex]\frac{6}{440} =\frac{P_2}{380}[/tex]

[tex]P_2[/tex] = [tex]\frac{6\times380}{440}[/tex]

[tex]P_2[/tex]= 5.18pounds per square inch

Step 1) Divide up the figure

In this figure, there is a triangle, a small rectangle, and two larger rectangles. The triangle is 6 in x 9 in, the small rectangle is 3 in x 18 in, one of the large rectangles (center) is 8 in x 14 in, and the other large rectangle (bottom) is 5 in x 9 in.

Step 2) Find the area of each shape in the figure

Triangle: A = 1/2 x 6 x 9 = 27

Small rectangle: A = 3 x 18 = 54

Large rectangle (center): A = 8 x 14 = 112

Large rectangle (bottom): A = 5 x 9 = 45

Step 3) Add the area of each shape together

A = 27 + 54 + 112 + 45 = 238 square inches

Hope this helps! :)

Answer:

247 square inches

Step-by-step explanation:

Divided the diagram into a triangle and three rectangles.

The triangle is 6 in * 6 in = 36 square inches

1st rectangle is 4 in * 3 in = 12 square inches

2nd rectangle is 11 in * 14 in = 154 square inches

3rd rectangle is 9 in * 5 in = 45 square inches

Therefore, 36+12+154+45 = 247 square inches

Answer:

x> -5

Step-by-step explanation:

The is an open circle at -5 and a line going to the right  so it is greater than ( no equals because the circle is open)

x> -5

Answer:

A) x > -5

Step-by-step explanation:

X value is more than negative 5 because you have an open circle at -5 which means value is greater or less but not equal (in our case it is greater) and since the arrow is going towards right (which are the postive values and numbers greater than -5), the answer is A, x>-5

Answer:

D

Step-by-step explanation: Plato test

Answer:

C

Step-by-step explanation:

The negative numbers should be the beginning ones because those are less than the positive ones. This eliminates D because it starts with 2/3, which isn't negative. -√3 is between -2 and -1, so it is greater than -5. This means that it should come after -5 in the sequence. The only option we are left with now is C. Hope this helps!

Answer:

41/35

Step-by-step explanation:

Simplify the following:

4/7 + 3/5

Put 4/7 + 3/5 over the common denominator 35. 4/7 + 3/5 = (5×4)/35 + (7×3)/35:

(5×4)/35 + (7×3)/35

5×4 = 20:

20/35 + (7×3)/35

7×3 = 21:

20/35 + 21/35

20/35 + 21/35 = (20 + 21)/35:

Answer:

60.63%

Step-by-step explanation:

Prob. of students who regularly attend = 45%

Prob. of students who don't attend = 55%

Upper Class Students who attend = 64 % of 45 %

= 0.64 × 0.45 × 100 = 28.8% = 0.288

Upper Class Students who don't attend = 34 % of 55% = 0.34 × 0.55 × 100 = 18.7% = 0.187

Total for Upper Class Students = 28.8% + 18.7% = 47.5% = 0.475

Probability that an Upper Class Student randomly selected will be attending = ( 0.288 / 0.475 ) × 100 = 0.6063 × 100 = 60.63%

Answer:

(B)25

Step-by-step explanation:

From the given diagram:

[tex]\angle ACE$ and \angle ECB[/tex] are on a straight line, and we know by the Linear Postulate that the sum of angles on a straight line is 180 degrees.

Therefore:

[tex]\angle ACE$ + \angle ECB=180^\circ$ (Linear Postulate)\\(2x+2)^\circ+(5x+3)^\circ=180^\circ\\$Collect like terms\\2x+5x+2+3=180\\7x+5=180\\$Subtract 5 from both sides\\7x+5-5=180-5\\7x=175\\$Divide both sides by 7\\7x\div 7=175\div 7\\x=25^\circ[/tex]

Answer:

468 square feet; Option C

Step-by-step explanation:

We can see that the base of this triangular prism has dimensions 15 feet by 10 feet, so for starters let us compute the area of this base:

Area ⇒ 15 * 10 = 150 ft^2

Now the rectangular surface next to this base, has dimensions 9 feet by 10 feet, provided that 9 feet is a uniform height of the triangular prism:

Area ⇒ 9 * 10 = 90 ft^2

This third rectangle is provided with one dimensions, of 10 feet. If we were to imagine what part of the 3-d shape is is, it would in fact be the slanted top. To find the second dimension, you would imagine it to be 12 feet. Using that, the area of this rectangle is thus ⇒ 10 * 12 = 120 ft^2

Now the two triangles at the corners each have an area of ⇒ 1/2 * base * height = 1/2 * 12 * 9 = 6 * 9 = 54 ft^2, so they have a total area of ⇒ 108 ft^2

This means the surface area of the right, triangular prism is:

150 + 90 + 120 + 108 = Answer: 468 square feet

Each point in the data set is near the regression line.

Option C is the correct answer.

Regression is a statistical method used to analyze the relationship between two or more variables.

It helps to identify and quantify the relationship between the dependent variable (also called the response variable) and one or more independent variables (also called the explanatory variables or predictors).

We have,

Each point in the data set is near the regression line.

This is because the regression line is the line of best fit that minimizes the distance between the line and the actual data points.

While not all points will fall exactly on the line, the fact that they are all relatively close to the line indicates that the line is a good fit for the data.

Option A is not necessarily true for all data sets, and option B is an overgeneralization.

Option D is not necessarily a problem, as a regression line does not always have to pass through the origin.

Thus,

Each point in the data set is near the regression line.

Answer:

The average verbal reasoning score: 152.4

The average quantitative reasoning score: 153.5

The analytical writing score: 9.2

Step-by-step explanation:

Let's call A the average verbal reasoning score, B the average quantitative reasoning score and C the analytical writing score.

Then, if the average quantitative reasoning score exceeded the average verbal reasoning score by 1.1 points, we can write the following equation:

B = A + 1.1     (eq. 1)

At the same way, if the average verbal reasoning score exceeded the analytical writing score by 143.2 points, we can write the following equation:

A = C + 143.2   or

C = A - 143.2          (eq. 2)

Finally, the sum of the three average scores was 315.1, so:

A + B + C = 315.1              (eq. 3)

Then, replacing equation 1 and 2 in equation 3:

A + B + C = 315.1

A + (A + 1.1) + (A - 143.1) = 315.1

Solving for A:

A + A + 1.1 + A - 143.2 = 315.1

3A = 315.1 - 1.1 + 143.2

3A = 457.2

A = 152.4

Replacing the value of A in equation 1 and 2:

B = A + 1.1 = 152.4 + 1.1 = 153.5

C = A - 143.2 = 152.4 - 143.2 = 9.2

So, the average score for each category is:

The average verbal reasoning score: 152.4

The average quantitative reasoning score: 153.5

The analytical writing score: 9.2

Answer:

Step-by-step explanation:

Answer: The other number is 100.

Step-by-step explanation:

The least common multiple (LCM) of two numbers is 200

The greatest common denominator (GCD) is 4.

One of the numbers is 8, which is the other number?

Ok:

First, we can write 8 as: 2*2*2 = 2^3 = 2*4

Now, the minimal common denominator can be any number that is written in the form

x = 4*a*b..

where a, b etc are prime numbers.

We also know that

LCD(a,b) = a*b/GCD(a,b)

LCD(8,x) = 8*x/GCD(8, x)

200 = 8*x/4

x = 200*4/8 = 100

the other number is 100.

Answer:

A) 129° B)66°

Step-by-step explanation:

A) A is 129° because the angle is alternate to it.

B) B is 66° because it the angle you would be trying to find would be alternate to that angle, however we do not yet have the angle. To find this angle, we will need to do 180-114 as angles on straight lines add up to 180°. 180-144 is subsequently 66°.
