c. How does the estimated value compare to the actual value
from the table when x is 2.3?
d. How does the estimated value compare to the actual value
from the table when x is 3?
Answers
(c) When x is 2.3, the predicted value is 0.02 less than the actual value first from database (d). When x is 3 and the predicted value is compared to the actual figure from the table, the residual is -1.27.
What would be an estimate?For instance, rounding these values with two decimal places to one nearest tenth (3.4 + 5.5) would result in an approximate reply of 8.9. The estimated result would be 9, but they might potentially be increased to the next full number (3 + 6). The correct response is 8.91.
(c). Nearly 6.2 Minus 6.18 = 0.02 separates the projected result from the actual value. As a result, there is hardly any change. The residual is thus 0.02
(d). Y Equals 4.47 whenever x = 3 because 2.45 × 3 + 11.82. Since the true value is 3.2 and the anticipated value is 4.47, the differences between the two is 1.27. The residual is thus 1.27.

When you multiply two terms by two terms, you should get four terms. Why is the final term result when you multiply two binomials sometimes only three terms? Give an example of how your final result can end up with only two terms
Answers
(a + b) * (a + b) = a * a + a * b + a * b + b * b = [tex]a^{2}[/tex] + 2ab + [tex]b^{2}[/tex]
This is an example of how the final result can end up with only three terms.
When you multiply two binomials, the result can sometimes have fewer than four terms because some of the terms may be combined or simplified.
The reason for this is that when you multiply two binomials, you use the distributive property, which states that you can multiply each term in one binomial by each term in the other binomial. The product of each pair of terms is a term in the final result.
For example, if you multiply (a + b) and (c + d), the final result will have four terms:
(a + b) * (c + d) = a * c + a * d + b * c + b * d
However, if one of the terms in either binomial is equal to zero, then the product of that term and the other term will be equal to zero, and that term will not appear in the final result:
(a + b) * (0 + d) = a * 0 + a * d + b * 0 + b * d = a * d + b * d
This is an example of how the final result can end up with only two terms.
Another way the final result can end up with only two terms is if two of the terms are equal to each other. When this happens, you can add them together and simplify the expression:
(a + b) * (a + b) = a * a + a * b + a * b + b * b = a^2 + 2ab + b^2
This is an example of how the final result can end up with only three terms.

Answers
The positive angle between 0 and 2 radians that is coterminal with the angle −143 radians is 1.057 radians, which is equal to 59.8°.
To find the positive angle in radians that is coterminal with −143 radians, we must first convert the negative angle to its equivalent positive angle. The angle −143 radians is equivalent to the angle 2π - 143 radians. We can calculate this by using the formula 2π + x = 2π - |x|, where x is the given angle. In this case, x = −143. Applying this formula, we get 2π + (−143) = 2π - |−143| = 2π - 143. This is the equivalent positive angle of the given negative angle. To find the positive angle that is coterminal with the positive angle we just found, we must subtract it from 2π until we get a value that is between 0 and 2π. To do this, we subtract 2π - 143 from 2π until we get a value that is between 0 and 2π. After subtracting 2π - 143 from 2π multiple times, we get the result 1.057 radians, which is equal to 59.8°. Therefore, the positive angle between 0 and 2 radians that is coterminal with the angle −143 radians is 1.057 radians.

A ball of mass 7 kg is thrown upward at an initial velocity of 20 m/s from a height of 50 m. The ball reaches a maximum height of 100 m before falling back to the ground. Calculate the potential energy of the ball at its highest point.
Answers
Step-by-step explanation:
The potential energy of an object can be calculated as the sum of its kinetic and gravitational potential energy. At its highest point, the ball has zero kinetic energy, so the potential energy is equal to its gravitational potential energy.
The gravitational potential energy of an object is given by:
PE = m * g * h
where m is the mass of the object (7 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the height above a reference point. In this case, the reference point is the ground, so h = 100 m.
Substituting in the given values, we find:
PE = 7 * 9.8 * 100 = 686 J
This is the potential energy of the ball at its highest point.

The triangle midsegment is a very important concept in geometry, and the triangle midsegment theorem states that the midsegment of a triangle is parallel to the third side and has a length equal to half of the length of the third side
The triangle midsegment theorem states that the midsegment of a triangle is parallel to the third side of the triangle and has a length that is equal to half of the length of the third side.
In this explanation, we will define the midsegment of a triangle and explain the triangle midsegment theorem in more detail.
To begin, let's consider a triangle ABC with midpoints D and E on sides AB and AC respectively. The segment DE is the midsegment of triangle ABC.
According to the triangle midsegment theorem, the length of DE is equal to half the length of the third side of the triangle, BC. Mathematically, this can be represented as follows:
DE = BC/2
In addition to the length, the midsegment of a triangle is also parallel to the third side. This means that if we extend the midsegment, it will eventually intersect the third side of the triangle.
The triangle midsegment theorem states that the midsegment of a triangle is parallel to the third side and also has the same length as half of the third side.

Answers
Answer:
b = 93° , c = 87°
Step-by-step explanation:
b and 93° are vertically opposite angles and are congruent , then
b = 93°
c and 93° are a linear pair and sum to 180° , that is
c + 93° = 180° ( subtract 93° from both sides )
c = 87°
Answer:
b=93
c=87
Step-by-step explanation:
1. For b, the angle is 93 degrees because of the vertical angle theorem, where two straight lines intersect, forming two sets of linear pairs with congruent angles.
Therefore, that angle is 90 degrees.
2. For c, use the given angle that is provided, since angle C and the given angle are supplementary (equaling 180 degrees), we can subtract the total (180) from the part (93)
180 - 93 = 87
Maliyah buys a bus ticket to New Orleans, her favorite city in America. The original price of $120 . She uses a coupon code to get a 20% discount off of the original price . She is then charged a 6% tax on the discounted price . What is the final cost for Maliyah's bus ticket
Answers
As per unitary method, Maliyah's bus ticket to New Orleans will cost $101.76 after using a coupon code and paying the tax.
The Unitary Method is a problem-solving strategy that is used to break down complex problems into smaller, more manageable parts.
To determine the final cost of Maliyah's bus ticket to New Orleans, we will use the unitary method of problem solving. This method involves breaking down the problem into smaller parts and solving each part separately to find the final answer.
The first step is to find the discounted price of the ticket. To do this, we multiply the original price of $120 by the discount percentage of 20%.
$120 * 0.20 = $24
Next, we subtract this amount from the original price to get the discounted price.
$120 - $24 = $96
Next, we find the amount of tax charged on the discounted price by multiplying the discounted price by the tax rate of 6%.
$96 * 0.06 = $5.76
Finally, we add this amount to the discounted price to get the final cost of the ticket.
$96 + $5.76 = $101.76

Answer:
To find the change in the unemployment rate, we need to calculate the ratio of the decrease in the number of unemployed workers to the total number of workers in the country. If the number of unemployed workers decreased from 5.3 million to 3.9 million, then the decrease is 5.3 million - 3.9 million = 1.4 million.
The total number of workers in the country is equal to the population minus the number of unemployed workers, or 75 million - 5.3 million = 69.7 million.
So, the change in the unemployment rate is (1.4 million / 69.7 million) * 100% = 2.0%.

Answers
The number of cattle would be 136,000 and the comparable ratio would be 4/10.
What is the equivalent ratio?When we compare two ratios, they are said to be equivalent.
To determine whether two or more ratios are equivalent, they can be compared to one another.
For instance, ratios 1:2 and 2:4 are equivalent.
Equivalent ratios are two ratios with the same value.
By multiplying or dividing the two amounts by the same number, you may determine the corresponding ratio.
Finding equivalent fractions follows the same procedure.
So, an equivalent ratio is required by the question.
This refers to a fraction that is equal to 2/5 of the fraction between 700 and 799.
We multiply the numerator and denominator by the same amount to produce an equivalent fraction.
When we divide both by 2, we get:
(2*2)/(5*2) = 4/10
While working with thousands, tenths are helpful since subtracting a zero when taking a tenth makes it usable.
As a result, 1/10 would equal 34000, and 4/10 would equal four times that: 4(34000) = 136000.
Therefore, the number of cattle would be 136,000 and the comparable ratio would be 4/10.

Valerie walks 10 yards due East, then turns 60° toward North and walks 5 yards.
Which student is farther from the cafeteria? Explain how you know using a diagram and words.
Answers
The person that is farther from the cafeteria would be Valerie.
How is Valerie farther from the Cafeteria?To determine which student is farther from the cafeteria, we need to calculate the distance each student has traveled from the cafeteria.
For Russell, his total displacement can be calculated using vector addition:
10 yards (due West) + 5 yards (South of West) = 10.87 yards at an angle of 305° from due West.
For Valerie, her total displacement can be calculated using vector addition:
10 yards (due East) + 5 yards (North of East) = 12.5 yards at an angle of 75° from due East.
Since the magnitude of the vector representing Valerie's displacement is larger, she is farther from the cafeteria.
