a=d  1.co interior angle  2. are equal

b=c 1. co interior angle 2. are equal

A transversal that crosses two parallel lines creates alternate angles, which are a pair of angles. Alternative angles are often referred to as "Z-angles" or "alternate internal angles."

∠a=∠d (because co interior angle i.e, a and d are equal)

∠b=∠c (because co interior angle i.e, b and c are equal)

Both sides are parallel, so co interior angle rule satisfies.

Hence, a=d  1.co interior angle  2. are equal

b=c 1. co interior angle 2. are equal

Co-interior angles form between two parallel lines when a transversal crosses them. On the same side of the transversal, the two angles always sum to 180 degrees. Drawing a C shape helps us identify co-interior angles rather frequently. Only when both inner angles are 90 degrees are they equal.

Step-by-step explanation:

To find the lower, middle, and higher quartiles of the given data set, we need to first order the data from lowest to highest:

5, 6, 7, 8, 9, 10, 12, 14, 15, 17, 18, 19

The total number of values in the set is 12, so the middle value (or the median) will be the average of the 6th and 7th values:

Median = (9 + 10) / 2 = 9.5

To find the lower quartile (Q1), we take the median of the lower half of the data set, which includes the first six values:

Lower half: 5, 6, 7, 8, 9, 10

Q1 = median of the lower half = (7 + 8) / 2 = 7.5

To find the higher quartile (Q3), we take the median of the upper half of the data set, which includes the last six values:

Upper half: 12, 14, 15, 17, 18, 19

Q3 = median of the upper half = (15 + 17) / 2 = 16

Therefore, the lower quartile is 7.5, the middle quartile is 9.5, and the higher quartile is 16.

The probability of making a basket on the sixth shot is 0.075. The probability that the first and second baskets occur on the fourth and eighth shots is 0.031.

For the first shot to be on the sixth trial, five earlier shots must have failed.

The probability of a missed basket is 1 - 0.45 = 0.55.

The probability of five missed baskets in a row is (0.55)5 = 0.166.

The probability of making a basket on the sixth shot is 0.45.

Hence, the probability of making a basket on the sixth shot is 0.45 * 0.166 = 0.075.
There are a few possible ways to get the first and second baskets to happen on the fourth and eighth shots, respectively.

In the end, either of the following two paths will work:
4 failures, then 2 successes, then 2 failures
3 failures, then 1 success, then 1 failure, then 1 success, then 2 failures
Using the multiplication rule, we get the following probabilities for each course:
P(4 failures, 2 successes, 2 failures) = (0.55)4 * (0.45)2 * (0.55)2

= 0.018
P(3 failures, 1 success, 1 failure, 1 success, 2 failures) = (0.55)3 * (0.45) * (0.55) * (0.45) * (0.55)2

= 0.013
The probabilities of the two possible routes must be summed up to arrive at the answer.
Hence, the probability that the first and second baskets occur on the fourth and eighth shots, respectively, is 0.018 + 0.013 = 0.031.

Step-by-step explanation:

No solution.

The two equations represent two different lines with the same slope (6), but different y-intercepts (9 for equation C and 2 for equation D). Since lines with different slopes will intersect at one point, and these two lines have the same slope but different y-intercepts, they are parallel and will never intersect. Therefore, there are no solutions to the system of equations.

The number of sides of the polygon is equal to the sum of the interior angles divided by the sum of the exterior angles, multiplied by two.

The number of sides of a polygon can be determined by examining the measures of its interior and exterior angles. The sum of the measures of the interior angles of the polygon is twice the sum of the measures of the exterior angles. Therefore, the number of sides of the polygon can be calculated by dividing the sum of the interior angles by the sum of the exterior angles and then multiplying that result by two. This is because the number of interior and exterior angles in a polygon are directly related. The sum of the interior angles is always equal to (n-2) times 180 degrees, where n is the number of sides of the polygon. Likewise, the sum of the exterior angles is always equal to 360 degrees. Therefore, the number of sides of the polygon is equal to (sum of the interior angles divided by the sum of the exterior angles) multiplied by two.

Using the Rational Zero Theorem to find all real zeros for given expression are:

[tex]$-\frac{1}{3}, 1$$[/tex]

What is rational zero theorem?

The Rational Zero Theorem is a theorem in algebra that helps find possible rational zeros (roots) of a polynomial equation with integer coefficients. The theorem states that if a polynomial equation with integer coefficients:

ax^n + bx^(n-1) + ... + kx + l = 0

has any rational roots, then they must be of the form: p/q, where p is a factor of the constant term l, and q is a factor of the leading coefficient a.

To use the Rational Zero Theorem, we need to find all possible rational zeros of the polynomial:

[tex]$$3x^3 - 5x^2 + 7x + 3 = 0$$[/tex]

The possible rational zeros are given by:

[tex]$$\pm\frac{p}{q}$$[/tex]

where [tex]$p$[/tex] is a factor of the constant term 3 and [tex]$q$[/tex] is a factor of the leading coefficient 3. Therefore, the possible rational zeros are:

[tex]$$\pm 1, \pm 3, \pm \frac{1}{3}$$[/tex]

To find the real zeros, we can use synthetic division or long division to divide the polynomial by each of the possible rational zeros. After testing each possible zero, we find that the real zeros of the polynomial are:

[tex]$x=-\frac{1}{3}, x=1$$[/tex]

Therefore, the solution is:

Answer:

Step-by-step explanation:

34. To calculate how much of Archie's hourly income the $15 sales tax represents, we need to divide $15 by Archie's hourly wage:

$15 ÷ $10.25 = 1.46 hours

So the $15 sales tax represents 1.46 hours of Archie's hourly income.

35. To calculate how much of Jeff's hourly income the $15 sales tax represents, we need to divide $15 by Jeff's hourly wage:

$15 ÷ $4400 = 0.0034 hours

So the $15 sales tax represents 0.0034 hours of Jeff's hourly income.

36. The sales tax impacts Archie more than Jeff because $15 represents a larger proportion of Archie's income than Jeff's income. For Archie, $15 represents about 14% of his hourly wage, while for Jeff, $15 represents only about 0.03% of his hourly wage.

37. If the sales tax increases to 12%, Archie would need to pay an additional 2% in sales tax (12% - 10%). So the new sales tax on a $150 bill would be:

$150 x 0.12 = $18

And the amount of sales tax Archie would need to pay would be:

$18 x 0.45 = $8.10

To calculate the percentage of Archie's income that he would now pay in tax on his $150 bill, we need to divide $8.10 by Archie's hourly wage:

$8.10 ÷ $10.25 = 0.79 hours

So Archie would need to work 0.79 hours to pay the sales tax on a $150 bill. As a percentage of his income, this is:

(0.79 hours x 100) ÷ 19 hours (assuming a typical workweek) = 4.16%

So if the sales tax increases to 12%, Archie would need to pay 4.16% of his income in sales tax on a $150 bill.

38. Archie might make adjustments to his purchases if the sales tax increases to 12%. For example, he might choose to buy cheaper or less expensive food items to reduce the amount of sales tax he needs to pay. He might also choose to buy some items in bulk to take advantage of lower prices and reduce the frequency of his purchases.

39. To calculate how much of Jeff's income the $18 sales tax would represent at a 12% rate, we can use the same method as before:

$18 ÷ $4400 = 0.0041 hours

So the $18 sales tax would represent 0.0041 hours of Jeff's hourly income.

40. Jeff might not make any adjustments to his purchases if the sales tax increases to 12%. Because he has a much higher income than Archie, the increase in sales tax would represent a relatively small proportion of his income. He might choose to continue purchasing the same types of food and luxury items as before, without significantly altering his spending habits.

41. Archie is impacted the most by the sales tax increase because he has a lower income than Jeff, so the sales tax represents a larger percentage of his income. While both Archie and Jeff would need to pay the same amount of sales tax on a $150 bill, the impact of that sales tax is much greater for Archie than it is for Jeff.

Answer:

Step-by-step explanation:

To find the percentage decrease, we need to calculate the difference between the original price and the new price, and then express that difference as a percentage of the original price.

The difference between the original price of $115 and the new price of $69 is:

$115 - $69 = $46

To express this as a percentage of the original price, we need to divide the difference by the original price and multiply by 100:

($46 / $115) x 100% = 40%

Therefore, the percentage decrease in the price of the item is 40%.

The length of side AB of the isosceles triangle is 8x + 5.

The formula for finding the length of a isosceles triangle side is given by:

Length of side = √x² +  y²

Where x and y are the lengths of the other two sides.

To find the length of the side AB, we need to first calculate x and y. We know that BC = 4x + 4 and CA = 3x + 9.

Therefore, [tex]x = BC - CA = 4x + 4 - 3x - 9 = x + -5[/tex]

And [tex]y = CA - BC = 3x + 9 - 4x - 4 = -x + 5[/tex]

Substituting these values in the formula, we get:

Length of side AB = √((x + -5)² + (-x + 5)²)

= √((x² + 25) + (x² + 25))

= √(2x² + 50)

= √(2(8x + 5)²)

= √(16x2 + 80x + 25)

Answer:

To find the slope of line AB, we use the slope formula:

slope of AB = (yB - yA) / (xB - xA)

where A = (-10, 8) and B = (2, 3).

slope of AB = (3 - 8) / (2 - (-10)) = -5/12

The slope of a line perpendicular to AB will have a negative reciprocal slope, so its slope will be 12/5.

Using the slope-intercept form of the equation of a line:

y = mx + b

where m is the slope and b is the y-intercept, we can find the equation of the line that passes through point X (-5, 10) and has a slope of 12/5.

10 = (12/5)(-5) + b

10 = -24/5 + b

b = 74/5

Therefore, the equation of the line that is perpendicular to AB and passes through point X is:

y = (12/5)x + 74/5

The size of the square that should be cut out of each corner to get a bin with maximum volume is 8 inches.

Let's assume that we cut out a square of side length x from each corner of the plastic piece. After cutting out the squares, the remaining length of the rectangle will be 32-2x inches, and the remaining width will be 42-2x inches.

The height of the bin will be x inches, since we fold up the flaps on each side.

The volume of the bin will be

V = (length) × (width) × (height)

= (32-2x) × (42-2x) × x

To find the value of x that maximizes the volume, we need to take the derivative of V with respect to x, set it equal to zero, and solve for x

dV/dx = 4x^3 - 148x^2 + 1344x

= 4x(x^2 - 37x + 336)

Setting this expression equal to zero and solving for x, we get

x = 8 inches, x = 21 inches, or x = 0 inches

However, x = 0 inches would result in no bin being formed.

To determine which value of x maximizes the volume, we need to evaluate V at each critical point

V(8) = 2688 cubic inches

V(21) = 1176 cubic inches

STEP 1: Determine the probability the spinner lands on a multiple of 3. To do this, write out the numbers on the spinner (1-8), and cross out every non-multiple of three (1, 2, 4, 5, 7, 8), this will leave the numbers 3 and 6 unmarked. This being said, 2/8 (1/4) of the numbers on the spinner are multiples of 3.

STEP 2: Determine the probability the spinner lands in a dark green region. In order to do this, write the numbers on the spinner out (1-8), and circle every number representing a dark green region (1, 3, 5, 7). This should leave four numbers (2, 4, 6, 8) un-circled, meaning 4/8 (1/2) of the numbers represent a dark green region.
