Step-by-step explanation:

Stress distribution can exist for a body in equilibrium if sigma x = - 2c1xy, sigma y = c2z2, sigma z = 0 tau xy = c1(c2 - y2) + c3xz, tau xz = -c3y, tau yz = 0.

Stress equilibrium specifies the pressure state of a body for a given external force field or body force distribution. The principle of stress equilibrium implies that the sum of the forces acting on the free body in equilibrium is zero, as well as the sum of the moments equal to zero.σx is the normal stress in the x direction that arises from the x-direction force acting on the plane. σy is the normal stress in the y direction that arises from the y-direction force acting on the plane.

σz is the normal stress in the z direction that arises from the z-direction force acting on the plane.τxy is the shear stress that arises from forces acting parallel to the xy plane. τxz is the shear stress that arises from forces acting parallel to the xz plane.τyz is the shear stress that arises from forces acting parallel to the yz plane.

Since there are no body forces acting on the object, it must be in equilibrium. The stress tensor is assumed to be symmetric, and the shear stresses must be equal. This is due to the plane orientation being perpendicular to the y-axis, which eliminates the need for a shear stress. As a result, we conclude that this stress distribution can exist for a body in equilibrium.

When looking at sides AC and CB, the included angle is angle ABC. The included angle is the angle between two given sides. In this particular question, we are given the sides AC and CB.

Here, we have a triangle ABC, and we are interested in the angle between sides AC and CB. This angle is opposite to the side AB. Therefore, this included angle is angle ABC. We can summarize this as follows: When we have two sides of a triangle, we can determine the included angle by finding the angle that lies between them. In the case of sides AC and CB, the included angle is the angle that is opposite to the third side of the triangle, AB.

Therefore, the included angle in this case is angle ABC.

x = 4 and x = -1/2 are real zeros of the polynomial

To find all the real zeros of the polynomial p(x) = 2x³ - 15x² + 24x + 16, we can follow these steps:

Step 1: Identify potential rational zeros using the Rational Root Theorem.
The Rational Root Theorem states that any potential rational zeros will be of the form ±p/q, where p is a factor of the constant term (16) and q is a factor of the leading coefficient (2). In this case, the possible rational zeros are ±1, ±2, ±4, ±8, ±1/2, ±2/2 (±1), and ±4/2 (±2).

Step 2: Test each potential rational zero using synthetic division.
We can use synthetic division to test each potential rational zero. If the remainder is 0, the potential rational zero is a real zero of the polynomial.

Step 3: Check for any irrational zeros using the quadratic formula.
If we find a quadratic factor during synthetic division, we can use the quadratic formula to find any remaining irrational zeros.

The point (-5, 3) shows the coordinates of c(5, 3) if the trapezoid ABCD on a coordinate plane, with points (2, 1), (3, 5), (5, 3) and (3, 1), is reflected across the y-axis. So the option A is correct.

A graph will appear to be inverted or on the other side of an axis, such as the x axis, when it is mirrored along that axis.

If you look closer, you'll notice that it's symmetrical, meaning that each point is equally spaced from the axis of reflection and the axis of its reflection.

As a result, if you reflect a point (x, y) down the x axis, its x abscissa will remain the same while its y ordinates will negate.

So (x, y) becomes (x, -y).

Similar to this, the picture of a point at coordinates (x, y) along the y axis will be (-x, y)

Trapezium A B C D on a coordinate plane has points (2, 1), (3, 5), (5, 3), and (3, 1).

The following rule applies when a point is reflected across the y-axis:

(x, y) → (-x, y)

C(5, 3) = C'(-5, 3)

So the option A is correct.

In this problem, the lower limit of integral is -3 and the upper limit of integration is 3.

We can use the formula for the surface area of a solid of revolution generated by a curve revolving around a given axis. The formula is S = 2π ∫ a b y dx, where a and b are the lower and upper limits of integration, and y is the height of the curve at x. In this problem, the lower limit of integration is -3 and the upper limit of integration is 3. Substituting y = 1/16(e^8x + e^-8x) into the equation gives S = 2π ∫ -3 3 (1/16(e^8x+e^-8x)) dx.

Answer:

Percentage of people with IQ greater than 120 is 84.134%

Step-by-step explanation:

First thing we do here is to calculate the

z-score

Mathematically;

z-score = (x-mean)/SD

here, x = 120, mean = 100 while SD = standard deviation = 20

z-score = (120-100)/20 = 20/20 = 1

The probability we want to calculate is;

P(x > 120) or P(z >1)

we proceed to use the standard score table to get this;

From the standard score table ;

P(z >1) = 0.84134

which is in percentage = 84.134%

Answer: B = 1

Step-by-step explanation:

You want to get b alone, first, you will subtract 3.6. What you do on one side you do to the other

3(1.2b - 1) + 3.6 = 4.2

3(1.2b - 1) + 3.6 - 3.6 = 4.2 - 3.6

Since the 3 is multiplied, we will do the opposite to eliminate it, Divison. So divide each side by 3.

3(1.2b - 1) = 0.6

3(1.2b - 1)/3 = 0.6/3

Then we will add one to each side.

1.2b - 1 = 0.2

1.2b - 1 + 1 = 0.2 + 1

The last step is to divide each side by 1.2 to find b.

1.2b = 1.2

1.2b/1.2 = 1.2/1.2

b = 1

To find P(Q and R), we can use the formula: P(Q and R) = P(Q) × P(R) Since the events Q and R are independent, we can multiply the probabilities of each event to find the probability of both events occurring together. P(Q) = 0.37P(R) = 0.24P(Q and R) = P(Q) × P(R) = 0.37 × 0.24 = 0.0888.

Therefore, the probability of both Q and R occurring together is 0.0888. Long Answer:Independent events:In probability theory, two events are independent if the occurrence of one does not affect the probability of the occurrence of the other. Two events A and B are independent if the probability of A and B occurring together is equal to the product of the probabilities of A and B occurring separately. Mathematically,P(A and B) = P(A) × P(B) Suppose Q and R are independent events. Find P(Q and R).

We can use the formula: P(Q and R) = P(Q) × P(R) Since the events Q and R are independent, we can multiply the probabilities of each event to find the probability of both events occurring together. P(Q) = 0.37P

(R) = 0.24

P(Q and R) = P(Q) × P(R)

= 0.37 × 0.24

= 0.0888

Therefore, the probability of both Q and R occurring together is 0.0888. Hence, P(Q and R) = 0.0888. In probability theory, independent events are the events that are not dependent on each other. It means the probability of one event occurring does not affect the probability of the other event occurring.
