Answer: There are 8 11-year-old students and 22 12-year-old students in Liam's class.

Step-by-step explanation:

Let's call the number of 11-year-old students in class x. Then, the number of 12-year-old students in the class would be 30 - x.

The total number of years that the 11-year-old students represent is 11 * x.

The total number of years that the 12-year-old students represent is 12 * (30 - x).

The sum of all the years is 352, so we can set up an equation based on the above information:

11x + 12(30 - x) = 352

Expanding the second term on the left-hand side:

11x + 360 - 12x = 352

Combining like terms:

-x + 360 = 352

Subtracting 360 from both sides:

-x = -8

Dividing both sides by -1:

x = 8

So, there are 8 11-year-old students and 30 - 8 = 22 12-year-old students in Liam's class.

The class that has more students, given the percentage of students in both classes is Emily's homeroom tab .

To find the class with the higher number of students, you need to find the total number of students in these classes.

The number of students in Emily's homeroom class is:

= Number of students / Percentage of students

= 15 / 75 %

= 20 students

Students in Santiago's homeroom class is :

= 12 / ( 2 / 3 )

= 12 x 3 / 2

= 18 students

The probability that a timing belt lasts until the car runs 140,000 miles is 0.9332.

a) The probability that a timing belt lasts until the car runs 140,000 miles can be found using the Z-score formula. The Z-score is calculated as (140,000 - 125,000)/10,000 = 1.5. The probability can be found using the Z-score table or by using a calculator, and is equal to 0.9332.

b) The probability that the timing belt fails before the car reaches the manufacturer’s recommended mileage of 90,000 miles can be found using the Z-score formula. The Z-score is calculated as (90,000 - 125,000)/10,000 = -2.5. The probability can be found using the Z-score table or by using a calculator, and is equal to 0.0062.

c) The 1st percentile of a normal distribution is the Z-score corresponding to the cumulative probability of 0.01. The Z-score for the 1st percentile is -2.33. The mileage of the car when the timing belt should be replaced can be found using the Z-score formula. The mileage is equal to 125,000 - (2.33 * 10,000) = 110,700 miles.

Tt is also possible neither y nor z is x.

Now, According to the question;

The x and y-axis are two important lines of the coordinate plane. The x-axis is a horizontal number line and the y-axis is a vertical number line. These two axes intersect perpendicularly to form the coordinate plane. The x-axis is also called the abscissa and the y-axis is called the ordinate.

If x is true, a non true statement cannot be the same as it.

Now, In symbolic logic, = doesn't mean two statements have the same value—it means they are the same literal statement.

So, if x is true, and y and z contradict, at least one of y and z is false, and that false statement cannot possibly be x.

Hence,  it is also possible neither y nor z is x.

The solution to the system of equations is (0.839, 1.129).

What is a graph ?

Graph can be defined as visual representation of the data through the given ordered pairs .

Given ,

The graph of a line passes through the points (0, 0.5) and (6, 5). A second i has the equation 5y = 7-6x.

The equation of the first line can be found using the two given points, using the slope-intercept form:

y = mx + b

where m is the slope and b is the y-intercept. To find the slope, we can use the formula:

m = (y2 - y1) / (x2 - x1)

Plugging in the values from the two points, we have:

m = (5 - 0.5) / (6 - 0) = 4.5 / 6 = 0.75

So the equation of the first line is:

y = 0.75x + 0.5

To find the solution to the system of equations, we need to find the point where the two lines intersect, which means finding the values of x and y that satisfy both equations. To do this, we can substitute the equation of the first line into the second equation:

5y = 7 - 6x

0.75x + 0.5 = 7 - 6x

Solving for x, we get:

7.75x = 6.5

x = 6.5 / 7.75 = 0.839

Substituting x back into either equation to find y, we get:

y = 0.75x + 0.5 = 0.75 * 0.839 + 0.5 = 0.629 + 0.5 = 1.129

So the solution to the system of equations is (0.839, 1.129).

Therefore, The solution to the system of equations is (0.839, 1.129).

The volume V of the solid obtained by rotating the region bounded by the given curves y = 2[tex]e^{-x}[/tex], y = 2, x = 4; about y = 4 is 256π.

The volume of the solid obtained by rotating the region bounded by the given curves about the line y=4 is given by

V = 2π ∫⁴₀ (4-2[tex]e^{-x}[/tex])² dx

We can calculate the integral using integration by parts.

Let u = 4-2[tex]e^{-x}[/tex]

⇒ du = 2d[tex]e^{-x}[/tex]

and dv = 2dx

⇒ v = x

So,

V = 2π ∫⁴₀ (4-2[tex]e^{-x}[/tex])² dx

 = 2π (x (4-2[tex]e^{-x}[/tex])²  - 0 (4-2[tex]e^{-x}[/tex]})²  - 2∫⁴₀ x d (4-2[tex]e^{-x}[/tex]))

 = 2π (2×4³ - 4∫⁴₀ x [tex]e^{-x}[/tex] dx)

Using integration by parts again

Let u = 4-2[tex]e^{-x}[/tex] ⇒ du = -2d[tex]e^{-x}[/tex]

and dv = xdx ⇒ v = x²/2

So,

V = 2π (2×4³ - 4∫⁴₀ x [tex]e^{-x}[/tex] dx)

 = 2π (2×4³ - 2×2∫⁴₀ x² [tex]e^{-x}[/tex] dx)

Again we can calculate the integral using integration by parts.

Let u = x² ⇒ du = 2xdx

and dv = [tex]e^{-x}[/tex] dx ⇒ v = -[tex]e^{-x}[/tex]

So,

V = 2π (2×4³ - 2×2∫⁴₀4 x^2 [tex]e^{-x}[/tex]} dx)

 = 2π (2 × 4³-2 × 2 × ([tex]-e^{-4}[/tex] + 2∫⁴₀  [tex]e^{-x}[/tex]dx))

 = 2π (2×4³ - 2×2 (1+4))

 = 2π (2×4³ - 16)

 = 2π (128-16)

 = 256π

Therefore, the volume V of the solid obtained by rotating the region bounded by the given curves y = 2[tex]e^{-x}[/tex], y = 2, x = 4; about y = 4 is 256π.

The mean, median, and mode are all equal to 100, and 68% of the scores are between 85 and 115. The third choice is also true, as 60% of test-takers earned at least a 100.

The normal curve is a symmetrical bell-shaped distribution with the mean, median, and mode all equal to 100. If we take 15 as the standard deviation, then 68% of the scores will lie between 85 (100-15) and 115 (100+15). We can calculate this using the z-score formula: z=(x-μ)/σ, where x is the score, μ is the mean, and σ is the standard deviation.

In this case, the z-score for the lower limit (85) is (85-100)/15=-1. The z-score for the upper limit (115) is (115-100)/15=1. We can then use the z-score table to determine that the area between -1 and 1 is 68%. Therefore, 68% of the scores are between 85 and 115.

To determine the percentage of test-takers who earned at least a 100, we can use the same z-score formula. The z-score for x=100 is (100-100)/15=0. We can then use the z-score table to determine that the area above 0 is 60%. Therefore, 60% of test-takers earned at least a 100.

Therefore, the first two choices are true. The mean, median, and mode are all equal to 100, and 68% of the scores are between 85 and 115. The third choice is also true, as 60% of test-takers earned at least a 100.
