In summary: P(z ≥ -1.57) = 0.9394,P(-1.95 ≤ z ≤ 0) = 0.4750,P(z ≤ 2.60) = 0.9953.To find the indicated probabilities, we can use the standard normal distribution table or a calculator.

Here are the calculations:

1. P(z ≥ -1.57):

This represents the probability of z being greater than or equal to -1.57. Using the standard normal distribution table, we can find the corresponding area under the curve. Looking up -1.57 in the table, we find the area to be 0.9394 (or 93.94%).

Therefore, P(z ≥ -1.57) = 0.9394.

2. P(-1.95 ≤ z ≤ 0):

This represents the probability of z being between -1.95 and 0. To find this probability, we need to find the area under the curve between these two z-values. Using the standard normal distribution table, we find the area for -1.95 to be 0.0250 (or 2.50%) and the area for 0 to be 0.5000 (or 50.00%). Subtracting these two values, we get:

P(-1.95 ≤ z ≤ 0) = 0.5000 - 0.0250 = 0.4750 (or 47.50%).

3. P(z ≤ 2.60):

This represents the probability of z being less than or equal to 2.60. Using the standard normal distribution table, we find the area for 2.60 to be 0.9953 (or 99.53%).

Therefore, P(z ≤ 2.60) = 0.9953.

In summary:

P(z ≥ -1.57) = 0.9394

P(-1.95 ≤ z ≤ 0) = 0.4750

P(z ≤ 2.60) = 0.9953

The length of the red side is 9.9 units. The length of the blue side is 4.5 units. Using the Pythagorean Theorem, the length of the black side is 9.0 units (rounded to the nearest tenth).

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

Length refers to the measurement of something from one end to the other. It is usually expressed in units such as meters, centimeters, inches, or feet.

According to the given information:

To find the length of the black side using the Pythagorean theorem, we need to first find the lengths of the red and blue sides.

Let's label the coordinates:

A = (4.5, 2)

B = (-4, -2)

C = (4.5, -2)

The length of the red side, AB, is given by the distance formula:

AB = √((4.5 - (-4))² + (2 - (-2))²) = √(8.5² + 4²) = √(85.25) ≈ 9.2

The length of the blue side, BC, is also given by the distance formula:

BC = √((4.5 - 4.5)² + ((-2) - (-2))²) = √(0 + 0) = 0

Now we can use the Pythagorean theorem to find the length of the black side, AC:

AC² = AB² + BC²

AC² = 85.25 + 0

AC² = 85.25

AC ≈ 9.2

Therefore, the length of the black side is approximately 9.2 units.

Step-by-step explanation:

The correct answer is c. 2.

To evaluate ∫cF · dx along the line segment C' from (0, 0, -1) to (1, 0, 0), we substitute the parametric equations of C' into the integrand F.

The parametric equations of C' can be written as:

x = t, y = 0, z = -1 + t

where t varies from 0 to 1.

Substituting these values into F = V(x² - y² - z²), we have:

F = V(t² - 0 - (-1 + t)²)

 = V(t² - (1 - 2t + t²))

 = V(t² - 1 + 2t - t²)

 = V(2t - 1)

Now, we evaluate ∫cF · dx:

∫cF · dx = ∫₀¹ V(2t - 1) · dt

Integrating with respect to t, we get:

∫cF · dx = V ∫₀¹ (2t - 1) · dt

        = V[t² - t] from 0 to 1

        = V[(1)² - 1] - V[(0)² - 0]

        = V(1 - 1) - V(0 - 0)

        = V(0)

        = 0

Therefore, the value of ∫cF · dx is 0, which corresponds to the option d. 1.

The number 22_1034 is not divisible by 9.

What is divisibility ?

Divisibility is a mathematical concept that describes whether one integer (a whole number) can be divided evenly by another integer, without leaving a remainder.

In other words, if we have two integers a and b, we say that a is divisible by b if and only if a can be expressed as a product of b and another integer without leaving a remainder. This is typically denoted by writing a divided by b as a fraction, and if the remainder is zero, we say that a is divisible by b.

According to the question:
To check if the number 22_1034 is divisible by 9, we can add up its digits and see if the sum is divisible by 9.

2 + 2 + 1 + 0 + 3 + 4 = 12 + 4 = 16

Segments AB and CD are not parallel, but they are perpendicular. Lines EF and GH are not parallel as well.

To determine which segments or lines are parallel, we need to analyze their slope. The slope of a line is determined by the change in y over the change in x. Given that x = 15 and y = 60, we can use the equation of a line in slope-intercept form, y = mx + b, to determine their slopes.
If we have two lines with the same slope, then they are parallel. Let's consider the following segments and lines:
1. Segment AB with endpoints A(0, 15) and B(15, 15).
The slope of this segment is (15 - 15) / (15 - 0) = 0. Therefore, this segment is horizontal and its slope is 0.
2. Segment CD with endpoints C(0, 60) and D(15, 45).
The slope of this segment is (45 - 60) / (15 - 0) = -1.5.
3. Line EF with equation y = 2x - 30.
The slope of this line is 2.
4. Line GH with equation y = -0.5x + 67.5.
The slope of this line is -0.5.
Using the slope analysis, we can conclude that segments AB and CD are not parallel since their slopes are different. Line EF and GH are not parallel either because their slopes are different. However, segments AB and CD are perpendicular to each other since the product of their slopes is -1, which is the characteristic of perpendicular segments.
In summary, segments AB and CD are not parallel, but they are perpendicular. Lines EF and GH are not parallel as well.

The three values known as quartiles divide sorted data into four equal-sized portions, each with an equal number of observations. An example of a quantile is a quantile. First quartile: Also referred to as the lower quartile or Q1. The median or second quartile is also referred to as Q2. Third quartile: Also referred to as the higher quartile or Q3.

Half of the difference between the upper and lower quartiles can be used to define the quartile deviation analytically. Here, the upper quartile (Q3) and lower quartile (Q1) can be used to depict quartile deviation as the letters QD. The term "quartile deviation" is sometimes used to refer to the semi-interquartile range.

The coefficient of quartile deviation serves as a gauge for a collection of data's variability or spread. It is determined by taking the square root of the difference between the upper and lower quartiles, squaring the result, and dividing it by two. Comparing data sets is simple because it is expressed as a percentage.

As the equation of tangent line is y = -3x, the value of slope, m is -3 and value of b is 0.

To find the equation of the tangent line at the point (π, -3π), we need to find the derivative of the function y = 3xcos(x), which is

y' = 3cos(x) - 3xsin(x)

and then evaluate the derivative at x = π to find the slope of the tangent line.

The slope at x = π is

m = 3cos(π) - 3πsin(π) = -3

So, the equation of the tangent line is y = -3x + b.

To find the value of b, we use the point (π, -3π) and the slope -3:

-3π = -3 * π + b

b = 0

So, the equation of the line tangent to the curve y = 3xcos(x) at the point (π, -3π) is y = -3x + 0 or simply y = -3x.

Jackie pays $130 monthly for her group health insurance.

To find out how much Jackie pays for her group health insurance monthly, we need to calculate 40% of the annual cost. Given that the annual cost is $3,900 and her company pays 40% of that, we can calculate the amount Jackie pays.

First, we find the company's contribution by multiplying the annual cost by 40%: $3,900 × 0.40 = $1,560. This is the amount the company pays towards Jackie's health insurance.

To determine Jackie's monthly payment, we divide her annual payment by 12 (months in a year) since she pays monthly. So, Jackie's monthly payment is $1,560 ÷ 12 = $130.

Therefore, Jackie pays $130 per month for her group health insurance. This calculation takes into account the company's contribution of 40% of the annual cost, resulting in an affordable monthly payment for Jackie.

There are 43 integers in the range from 92 to 734 that are divisible by 15. The probability that a random integer from 92 to 734 is divisible by 15 is approximately 0.067.

To find the probability that a random integer from 92 to 734 is divisible by 15, we need to first determine the total number of integers in this range. The difference between 734 and 92 is 642, but since we want to include both endpoints, we need to add 1 to this difference. So there are a total of 643 integers in the range from 92 to 734. Next, we need to determine how many of these integers are divisible by 15. To do this, we need to find the smallest multiple of 15 that is greater than or equal to 92, and the largest multiple of 15 that is less than or equal to 734. The smallest multiple of 15 that is greater than or equal to 92 is 105 (which is 7 times 15), and the largest multiple of 15 that is less than or equal to 734 is 720 (which is 48 times 15).

So the integers from 105 to 720 (inclusive) are all divisible by 15. To count the number of integers in this range, we can divide the difference between 720 and 105 by 15, and add 1 to account for the first multiple of 15:
(720 - 105) / 15 + 1 = 43
Therefore, there are 43 integers in the range from 92 to 734 that are divisible by 15.

To find the probability that a random integer from this range is divisible by 15, we can divide the number of integers that are divisible by 15 (43) by the total number of integers in the range (643):
43 / 643 ≈ 0.067
So the probability that a random integer from 92 to 734 is divisible by 15 is approximately 0.067.

D = 0; one real root

Step-by-step explanation:

Discriminant Formula:

\( \displaystyle \large{D = {b}^{2} - 4ac}\)

First, arrange the expression or equation in ax^2+bx+c = 0.

\( \displaystyle \large{ {x}^{2} + 6x = - 9}\)

Add both sides by 9.

\( \displaystyle \large{ {x}^{2} + 6x + 9 = - 9 + 9} \\ \displaystyle \large{ {x}^{2} + 6x + 9 = 0}\)

Compare the coefficients so we can substitute in the formula.

\( \displaystyle \large{a {x}^{2} + bx + c = {x}^{2} + 6x + 9 }\)

Substitute a = 1, b = 6 and c = 9 in the formula.

\( \displaystyle \large{D = {6}^{2} - 4(1)(9)} \\ \displaystyle \large{D = 36 - 36} \\ \displaystyle \large{D = 0}\)
