The total number of points scored is given by the equation A = 23 points

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total points scored be represented as A

Now , the equation will be

Substituting the values in the equation , we get

A = 3x + 2y + z   be equation (1)

where x = red team = 3 points

y = yellow team = 5 points

z = blue team = 2 points

So , A = 3 ( 3 ) + 2 ( 5 ) + 2

A = 9 + 10 + 2

A = 21 points

Hence , the equation is A = 21 points

Alternate interior angles are never supplementary would be two parallel lines being intersected by a transversal, such that one pair of alternate interior angles measures 180 degrees (i.e., they are supplementary). This would show that the statement is false and that alternate interior angles can indeed be supplementary.

When a transversal connects two coplanar lines, alternate interior angles are created. They are located on the transverse sides of the parallel lines, but on the inner side of the parallel lines.

A transversal intersection of two parallel lines produces same-side interior angles, whose sum is 180 degrees. As the sum of the same side interior angles is 180 degrees therefore the angles are supplementary.

b. The decision rule for treatments is to use an analysis of variance (ANOVA) with a significance level of 0.05. If the p-value is less than 0.05, we reject the null hypothesis and conclude that there is a difference in the mean production rate by shift.

c-1. The null hypothesis for the blocks is: μS = μL = μC = μT = μM

c-2. The alternate hypothesis for the blocks is: Not all means are equal. The decision rule for blocks is the same as for treatments, use an ANOVA with a significance level of 0.05. If the p-value is less than 0.05, we reject the null hypothesis and conclude that there is a difference in the mean production rate by employee.

The results indicate that there is a difference in the mean production rate by shift, but there is not enough evidence to conclude that there is a difference in the mean production rate by employee.

The circumference of the circle is 6.28 .

Circle is a closed figure or curve that we get by drawing a line which passes through the points which are at an equal distance from a common point.

Perimeter of a closed figure is the total length of the line used for making that closed figure.

For example if we have three sticks of Length 2 cm, 3 cm, 5 cm. We make a triangle using the above sticks so the perimeter of the triangle will be

       = 2+3+5= 10 cm

This indicates that total length of stick used to form the triangle is 10 cm.

For a circular figure its perimeter is known as circumference.

Now for the given question:

Diameter of the circle ( D ) = 2 yards.

π= 3.14         ( given in question)

Circumference of a circle = π×D

The probability of drawing a jack or a queen or a heart from a standard 52-card deck is 1/4.

Probability is an area of mathematics that deals with numerical representations of how probable an event is to occur or how likely a statement is to be true. The probability of an occurrence is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.

There are a total of 52 cards in a standard playing deck, and there are 4 jacks, 4 queens, and 13 hearts.

The probability of drawing a jack or a queen or a heart is equal to the sum of the probabilities of drawing each individual card type.

So, the desired probability is:

P(jack or queen or heart) = P(jack) + P(queen) + P(heart)

= 4/52 + 4/52 + 13/52

iii) The average velocity for the time period [1, 1.001] is equals to -22.023 ft/s.

B) The estimate value of the instanteneous velocity when t = 1s is equals to -22 ft/s.

The average velocity over an interval [a,b] for a defined position function f(t) can be displayed by the difference quotient {f(b)-f(a)}/{b-a}. When these two points come very close to each other and at any point both of them appear almost the same point then the average velocity becomes instantaneous velocity at that time, which is also the derivative of the function at that point. We have, baby alien throw a ball into the air with a velocity of 24 ft/s on planet. The height in feet or

the displacement relation is defined as ,

y (t) = 24t - 23t².

where, y--> displacement/height

t --> time

Initial time , to = 1 sec

Therefore, the velocity will be

dy/dt = v(t) = 24 - 46t

A) The average velocity on an interval [a,b] is

Vₐᵥ = { y( b) - y(a) }/(b - a)

Now, see the intervals ,

Vₐᵥ = {y( 1.01) - y(1)}/(1.01 - 1)

= {24(1.01) - 23(1.01)² - 24×1 + 23× 1 }/0.01

= {24.24 - 24 - 23.4623 + 23}/0.01

= - 22.23 ft/s

Vₐᵥ = {y( 1.005) - y(1)}/(1.005 - 1)

= {24(1.005) - 23(1.005)² - 24×1 + 23× 1 }/0.005

= -22.115 ft/s

Vₐᵥ = {y( 1.001) - y(1)}/(1.001 - 1)

= {24(1.001) - 23(1.001)² - 24×1 + 23× 1 }/0.001 = { 24.024 - 24 + 23 - 23(1.001)²}/0.001 = - 22.023 ft/s

B) The instanteneous velocity is defined as V (t) = dy/dt = 24 - 46t

At t = 1 s then V(t) = 24 - 46(1) = 24 - 46

=> V = - 22 ft/s

The volume of the solid generated by revolving the plane region about the x-axis is 125/6 units3.

The volume of the solid generated by revolving the plane region about the x-axis can be found by using the Shell Method. This method involves integrating the area of the cross-section of the solid with respect to the x-axis. The area of the cross-section can be found by calculating the area of the region bounded by the curve y=x and the origin, which is a triangle. The area of the triangle is 1/2 * base * height, or 1/2 * x * x. The definite integral that represents the volume of the solid is then given by:

[tex]V = ∫0 x (1/2 x2) dx[/tex]

Evaluating this integral yields[tex]V = (1/6 * x3)|0x[/tex]. Plugging in x=0 and x=5 yields [tex]V = (1/6 * 53)|0x = 125/6[/tex] units3. Therefore, the volume of the solid generated by revolving the plane region about the x-axis is 125/6 units3.

The displacement of the particle at t = 1 second is -3 .meters

The displacement of a particle in a straight line can be calculated using the following formula:  Displacement (d) = 2sin(πt) + 3cos(πt). This formula takes into consideration the sine and cosine of the angle, pi (π), multiplied by the time (t). The sine of the angle represents the vertical displacement, while the cosine represents the horizontal displacement.

For example, let's say we want to calculate the displacement of a particle at t = 1 second. First, we'll plug in the values into the formula:

d = 2sin(πt) + 3cos(πt)

d = 2sin(π*1) + 3cos(π*1)

d = 2sin(π) + 3cos(π)

d = 0 + (-3)

The standardized value for x = 2.69 is 0.

The standardized value (z) is given by:

z = (x - mean) / standard deviation

where x is the value to be standardized, mean is the normal distribution's mean, and standard deviation is the normal distribution's standard deviation.

So, for x = 2.69, with a mean of 2.69 and a standard deviation of 4.76, the standardized value (z) is:

z = (2.69 - 2.69) / 4.76 = 0

As a result, the standardized value for x = 2.69 is 0.

Standard deviation is a measure of the spread or dispersion of a set of data values around their mean (average). It provides a quantitative indication of how far apart each data value is from the mean and from each other. A low standard deviation means that the data values are close to the mean, while a high standard deviation indicates that the data values are more spread out.
