Step-by-step explanation:
The Griffins and the Corbins live in the same city and pay the same sales tax rate, and both families made $12,000 in taxable purchases last year. If the Griffins made $73,000 and the Corbins made $29,000 last year, is the sales tax in their city an example of a regressive tax?
A.Yes, because the Corbins paid a higher percentage of their income in sales tax than the Griffins did.
B.No, because the Corbins paid a higher percentage of their income in sales tax than the Griffins did.
C.No, because the Griffins and the Corbins both paid the same sales tax rate.
D.Yes, because the Griffins and the Corbins both paid the same sales tax rate.
Answer:
The correct answer is A.
Step-by-step explanation:
A.Yes, because the Corbins paid a higher percentage of their income in sales tax than the Griffins did.
Regressive tax is applied uniformly and this causes lower-income people to pay a larger share of their income than rich people. It is not a fair way though it seems to be. Most regressive taxes are not income taxes.
What is the length of BC¯¯¯¯¯ ?
Enter your answer in the box.
Answer: The required length of BC is 22 units.
Step-by-step explanation: We are given to find the length of BC from the figure.
From the figure, we note that ABC is an isosceles triangle, with AC = AB, where
AC = 2x-24, AB = x-2 and BC = x.
Since AC = AB, so we get
[tex]2x-24=x-2\\\\\Rightarrow 2x-x=24-2\\\\\Rightarrow x=22.[/tex]
Therefore, we get
BC = x = 22.
Thus, the required length of BC is 22 units.
What is the definition of principal square root in math?
Final answer:
The principal square root in math refers to the positive square root of a number. It is denoted as √x and is applicable to non-negative numbers.
Explanation:
The principal square root in math refers to the positive square root of a number. It is denoted as √x, where x is a non-negative number.
For example, the principal square root of 25 is √25 = 5 because 5 multiplied by itself equals 25.
The principal square root is only applicable to non-negative numbers, while negative numbers have no real square roots.
The sum of two numbers is 56. Their difference is 18.
The numbers are 37 and 19
From the question,
Let the numbers be x and y
From the first statement
The sum of two numbers is 56.
That is,
x + y = 56 --------- (1)
From the second statement
Their difference is 18
That is,
x - y = 18 ----------- (2)
Add equations (1) and (2)
x + y + x - y = 56 + 18
2x = 74
∴ x = 74 ÷ 2
x = 37
Substitute the value of x into equation (1) to determine the value of y
x + y = 56
37 + y = 56
y = 56 - 37
y = 19
∴ x = 37 and y = 19
Hence, the numbers are 37 and 19.

Find the measure of angle x in the figure.
Angle x measures?
Answer:
Measure of angle x is:
119°
Step-by-step explanation:
The sum of all interior angles in a polygon having n sides is:
180°(n - 2)
Now, this polygon has 7 sides.
So the sum of its interior angles will be= 180°(7 - 2)
= 900°
i.e. 129°+129°+123°+122°+x+141°+137°=900°
or 781°+x=900°
or x=900°-781°
or x=119°
Hence, Measure of angle x is:
119°

A long distance phone company charges $1.01 for the first 25 minutes of a call, then $0.09 for each additional minute. A call cost $9.56 how long did it last?
Final answer:
Subtracting the initial charge from the total cost and then dividing the remainder by the cost per additional minute, we find that the call lasted for 120 minutes.
Explanation:
The student is asking how long a phone call lasted based on the cost of the call with a given rate structure. We know that the first 25 minutes cost $1.01 and each additional minute costs $0.09. The total cost of the call was $9.56. To determine the duration of the call, we need to calculate the cost of the additional minutes beyond the first 25, and then find out how many of those minutes were used.
Subtract the initial charge from the total cost: $9.56 - $1.01 = $8.55.
Divide the remaining cost by the cost per additional minute: $8.55 / $0.09 = 95 minutes.
Add the initial 25 minutes to the additional minutes: 25 + 95 = 120 minutes.
Therefore, the call lasted for 120 minutes.

Solve the inequality.
q + 12 – 2(q – 22) > 0
q < 56
q > –32
q > 56
q < –32
Answer:
q<56
Step-by-step explanation:
An inequality is an algebraic expression that consists of two members separated by an inequality. The inequality can be <, ≤,>, ≥.
Solving an inequality consists in finding the value or values that verify it.
An inequality of the first degree is an inequality in which the variable is of degree one, as in this particular case.
In this case, the resolution must first eliminate the parentheses on the left side of the inequality. For that you apply distributive property. This property expresses that the multiplication of a number by a sum is equal to the sum of the multiplications of that number by each of the addends. So you get:
q+12-2*q-2*(-22)>0
q+12-2*q+44>0
Then the terms contained in "q" must be grouped on one side of the inequality and the independent terms on the other. In this case the terms with the variable "q" will remain on the left side of the inequality. The independent terms will be grouped on the right side, remembering that to take them to the other side of the inequality the opposite operations will be used. This is:
the opposite operation of the sum is the subtraction .the opposite operation of subtraction is the sum .the opposite operation of multiplication is division .the opposite operation of the division is multiplication.So:
q-2q>-12-44
Solving the corresponding addition and subtraction operations you get:
(-1)*q>-56
Since the coefficient that accompanies "q" is negative, it is multiplied by −1 on both sides of the inequality, so the direction of inequality will change.
q<56
Finally, the values for which the inequality is valid are those in which q is less than 56
Assume that we want to find the probability that when five consumers are randomly selected, exactly two of them are comfortable with delivery by drones. Also assume that 38% of consumers are comfortable with the drones (based on a survey). Identify the values of n, x, p, and q. The value of n is __. (Type an integer or a decimal. Do not round.) The value of x is __. (Type an integer or a decimal. Do not round.) The value of p is __. (Type an integer or a decimal. Do not round.) The value of q is ___ . (Type an integer or a decimal. Do not round.)
In the given problem, n (the number of trials) is 5, x (the amount of 'successes' we're seeking) is 2, p (the probability of success) is 0.38, and q (the probability of failure) is 0.62.
Explanation:In the given problem, we are conducting a binomial experiment where five consumers are randomly selected and we are interested in the number who are comfortable with drone delivery. So, the total number of trials, n, will be equal to the number of consumers selected, which is 5.
The value to be observed, x, is exactly 2, because we want to find out the probability of exactly two of them are comfortable with delivery by drones.
The probability of success, p, is the proportion of consumers that are comfortable with delivery by drones, so p = 0.38 (or 38%).
The probability of failure, q, is the proportion of consumers that are not comfortable with delivery by drones, so q = 1 - p = 1 - 0.38 = 0.62.
