The probability that the student is from other majors is 0.40, the probability that the student majors only math is 0.13, and the probability that the student does not major engineering is 0.73.

a) Probability of a student being from other majors = (150-90) / 150 = 0.40

b) Probability of a student majoring only math = (30 - 20) / 150 = 0.13

c) Probability of a student not majoring engineering = (150 - 40 - 20) / 150 = 0.73

Probability = Number of Favorable Outcomes / Total Number of Outcomes

For part a)

Number of Favorable Outcomes = 150-90 = 60

Total Number of Outcomes = 150

Therefore, Probability = 60 / 150 = 0.40

For part b)

Number of Favorable Outcomes = 30-20 = 10

Total Number of Outcomes = 150

Therefore, Probability = 10 / 150 = 0.13

For part c)

Number of Favorable Outcomes = 150-40-20 = 90

Total Number of Outcomes = 150

Therefore, Probability = 90 / 150 = 0.73

Answer:

-5/3.

Step-by-step explanation:

To find the slope of a line perpendicular to another line, we need to remember that the slopes of two perpendicular lines are negative reciprocals of each other. To find the slope of the line perpendicular to 3x - 5y = 45, we need to first convert it to slope-intercept form, which is y = mx + b, where m is the slope of the line.

First, isolate the y-term:

3x - 5y = 45

5y = -3x + 45

y = -(3/5)x + 9

So the slope of the original line is -3/5. The slope of the line perpendicular to it would be the negative reciprocal of this slope, which is -5/3.

Therefore, the slope of a line perpendicular to 3x - 5y = 45 is -5/3.

Answer:

3/5

y = -x²: vertical translation 1 unit upwards, y = x² + 1: vertical translation 1 unit upwards, y = -x² - 2: vertical translation 2 units downwards, y = -(x+1)² - 1: horizontal translation 1 unit to the left, reflected across the x-axis, y = -(x-1)² - 1: horizontal translation 1 unit to the right, reflected across the, y-axis, y = -x²: no transformation (same as the parent function)

The parent function is y = -x² - 1.

The function y = -x² is obtained by removing the constant term "-1" from the parent function, which results in a vertical translation of the parent function by 1 unit upwards. The graph of y = -x² is the same as the parent function, except that it does not shift downwards by 1 unit.

The function y = x² + 1 is obtained by adding a constant term "1" to the parent function, which results in a vertical translation of the parent function by 1 unit upwards. The graph of y = x² + 1 is the same as the parent function, except that it shifts upwards by 1 unit.

The function y = -x² - 2 is obtained by subtracting a constant term "2" from the parent function, which results in a vertical translation of the parent function by 2 units downwards. The graph of y = -x² - 2 is the same as the parent function, except that it shifts downwards by 2 units.

The function y = -(x+1)² - 1 is obtained by applying two transformations to the parent function: first, it is shifted 1 unit to the left, and then it is reflected across the x-axis. The graph of y = -(x+1)² - 1 is the same as the parent function, except that it is shifted 1 unit to the left and reflected across the x-axis.

The function y = -(x-1)² - 1 is obtained by applying two transformations to the parent function: first, it is shifted 1 unit to the right, and then it is reflected across the y-axis.

Because angles 1 and 2 are adjacent, we will see that the measure of angle 2 is 77°.

Here we know that m∠1 = 103°, and we want to find the measure of angle 2, which is an angle adjacent to angle 1.

That means that if we add their measures, then we will get a plane angle, this means that:

m∠1 + m∠2 = 180°

Then we can write:

103° + m∠2 = 180°

m∠2 = 180° - 103° = 77°

First, use the equation for a hemisphere. Since a sphere's equation is [tex]\frac{4}{3}\pi r^{3}[/tex], and a hemisphere is half a sphere, we can use the equation [tex]\frac{2}{3}\pi r^{3}[/tex]. We know the radius is 6 inches, and we can approximate pi as 3.14, so now let's plug in our values:

[tex]\frac{2}{3}\ (3.14) 6^{3}=\frac{2}{3} \ (3.14)(216)= \frac{2}{3}(678.16)= 452.16[/tex]

The volume of the hemisphere is about [tex]452.16 in^{3}[/tex].

The formula for the volume of a cone is [tex]\pi r^{2}\frac{h}{3}[/tex]. Again, let's plug in our values:

[tex](3.14)(36)\frac{6}{3} =(3.14)(36)(2)=(3.14)(72)=226.08[/tex]

The volume of the cone is about [tex]226.08 in^{3}[/tex].

Subtract 226.08 from 452.16 and you get 226.08.

The volume of the remaining solid will be [tex]226.08 in^{3}[/tex].

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent.

The two triangles triangle ABE and triangle CDE are similar triangles.

We know that, the ratio of segments of similar triangle are equal thus:

10 / 8 = 2x + 6 / x+ 6

10(x + 6) = 8(2x + 6)

10x + 60 = 16x + 48

60 - 48 = 16x - 10x

The expected value of the sample mean amount of money spent on books is equal to the population mean, which is $400.

This is a property of the sampling distribution of the sample mean, which states that the mean of all possible sample means is equal to the population mean.

In other words, if we take all possible random samples of size 100 from the population of undergraduate students, and calculate the mean amount of money spent on books for each sample, then the average of all these sample means will be $400.

The expected value of the sample mean amount of money spent on books can be calculated using the formula:

E(X) = μ

where X is the sample mean, and μ is the population mean.

In this case, the population mean is given as $400. Therefore, the expected value of the sample mean amount of money spent on books is also $400.

However, we can also calculate the standard error of the mean (SE) to get a measure of the variability of the sample mean. The formula for SE is:

[tex]SE = σ / sqrt(n)[/tex]

where σ is the population standard deviation, and n is the sample size.

Substituting the values, we get:

[tex]SE = 80 / sqrt(100) = 8[/tex]

This property is true regardless of the sample size, as long as the sample is randomly selected and independent. However, as the sample size increases, the sampling distribution of the sample mean becomes more normal and the standard error of the mean decreases, making the sample mean a more precise estimate of the population mean.

Length of the segments are 11 units and 10 units and measures of the angles are 54° and 126°.

Parallelogram is a type of polygon with four sides, four angles and four vertices. It is a type of Quadrilateral.

Opposite sides are parallel, and the opposite sides and opposite angles are equal.

Since, CDEF is a parallelogram, opposite angles are equal.

(9y)° = (7y + 28)°

9y - 7y = 28

2y = 28

y = 14

∠C = ∠E = 9y = 126°

Sum of the angles of a quadrilateral is 360°.

∠D = ∠F = (360° - (126°×2)) / 2 = 54°

Opposite sides are also equal for a parallelogram.

2x = x + 5

2x - x = 5

x = 5

CF = DE = 2x = 10 units

x + y = 6 + 9 = 15.

However, x + y does not equal 15. Hence, we can deduce that:

x + y = 15 [tex]\neq[/tex] 15.

15 does not equal 15, so if 15 is 15 and not equal to 15, we can prove that since 6 does not equal 9, 6 is 9. We can therefore conclude that we need to solve for x + x. Since we proved that something is something by not being something, 2x ix 2x but not 2x.

Answer:

w = 25 / 4 feet wide.

Step-by-step explanation:

Let's call the width of the walkway "w."

The area of the rectangular pool is 13 * 27 = 351 ft^2.

The area of the walkway can be calculated by adding up the area of four rectangles, one around each side of the pool:

2 * (13 + w) * w + 2 * (27 + w) * w = 384

Expanding the equation:

2 * 13w + 2w^2 + 2 * 27w + 2w^2 = 384

Combining like terms:

2w^2 + 40w = 384

Solving for w^2:

2w^2 + 40w - 384 = 0

Using the quadratic formula:

w = (-40 ± √(40^2 - 4 * 2 * -384)) / (2 * 2)

Simplifying:

w = (-40 ± √(1600 + 3072)) / 4

w = (-40 ± √4272) / 4

w = (-40 ± 65) / 4

w = (25 / 4) or (-105 / 4)

Since w must be a positive value, w = 25 / 4 feet wide.
