Which property is shown by the equation 23 + 0 = 23

The value of the car after 3 years is $79, 000

To determine the value, we have to use the formula;

Value = Initial value × (1 - Depreciation rate)ⁿ

Substitute the values given, we get;

Remaining value after 3 years = $100,000 × (1 - 0.10)³

Expand the bracket, we get;

Value after 3 years = $100,000 × (0.90)³

Find the cube value and substitute, we have;

Value after 3 years = $100,000 × 0.729

Multiply the values, we have;

Value after 3 years = $72,900

Answer: 20% of the time.

Step-by-step explanation: 5+3+2 = 10 There are 2 blue so 2/10=1/5=20%

Answer:

(3/2, 1/2)

Step-by-step explanation:

Solve by elimination:

\(x+y=2\\+x-y=1\)

The y's cancel

\(2x=3\)

Divide by 2

\(x=\frac{3}{2}\)

Plug back in

\(\frac{3}{2} +y=2\)

subtract

\(y=2-\frac{3}{2}\)

\(y=\frac{1}{2}\)

So, your answer:

\((\frac{3}{2},\frac{1}{2})\)

The percentage of the games the club has won is P = 77.78 %

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Let the total number of games = 18

The number of games they lost = 4

So , the number of games they won = 14 games

Now , the percentage of games they won = ( 14 / 18 ) x 100

On simplifying the equation , we get

A = 0.7778 x 100

A = 77.78 %

Hence , the percentage is 77.78 %

Step-by-step explanation:

We substitute -1+1/6y for x in the second equation (bottom equation) in order to solve the system by the substitution method.

The given system of equations are 2x-1/3y = -2...(1)

3x+y=1...(2)

We solve this system of equations by using substitution method.

Let us solve for x in equation to substitute it in equation (2).

2x=-2+1/3y

Divide both sides of equation by 2.

x=-1+1/6y

Now plug in the value of x in equation 2.

Hence, we substitute -1+1/6y for x in the second equation (bottom equation) in order to solve the system by the substitution method.

Approximately 99.7% of scores lie in the shaded region.

We have,

The empirical rule, also known as the 68-95-99.7 rule, provides an estimate of the percentage of scores that lie within a certain number of standard deviations from the mean in a normal distribution.

According to this rule:

Approximately 68% of scores lie within 1 standard deviation of the mean.

Approximately 95% of scores lie within 2 standard deviations of the mean.

Approximately 99.7% of scores lie within 3 standard deviations of the mean.

Now,

In the given scenario, the shaded region represents the area between -2 and 3 standard deviations from the mean on the x-axis.

This encompasses the area within 3 standard deviations of the mean.

And,

Since 99.7% of scores lie within 3 standard deviations of the mean, we can estimate that approximately 99.7% of scores lie in the shaded region.

Therefore,

Approximately 99.7% of scores lie in the shaded region.

Yet, the report makes no mention of any other candidates or possibilities,  percentage  leaving the remaining 10% of votes unaccounted for.

In mathematics, a percentage is a ratio or value stated as a percentage of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. Yet, the percentage symbol "%" is often used to indicate it. The % value is dimensionless. Percentages are fractions with a denominator of 100. A percent sign (%) should be placed next to a number to show that it is a percentage. For example, you get a 75% on a test if you correctly respond to 75 out of 25 pages (75/100). When calculating percentages, divide the result by 100 after dividing the amount by the total. The percentage is calculated by multiplying (value/total) by 100 percent.

The reader may argue that the story is not factual because Smith and Murphy's proportion of votes should total up to 100%. If Smith received 70% of the votes and Murphy obtained one-fifth of the votes, we can calculate Murphy's vote percentage as follows:

Answer:

a) 17 cm

b) 62

c) 28

Step-by-step explanation:

a) HT² = HW² + WT²

HT² = (15² + 8²) cm² = 225 + 64 = 289 cm²

HT = √289cm² = 17 cm

b) Sin(∠T) = HW/HT = 15/17 = 0.8824

∠T = Sin∧-1 (0.8824) = 62°

c) ∠H = 90°- 62° = 28°

The probability that it is raining and the flight is delayed is 0.011, or approximately 0.011 rounded to the nearest thousandth.

Let's use the formula for calculating the probability of the intersection of two events: P(A and B) = P(A) × P(B|A), where P(B|A) is the probability of event B occurring given that event A has occurred.

Let A be the event that it is raining, and B be the event that the flight is delayed. We are looking for P(A and B).

We know that:

P(A) = 0.1 (the probability that it will rain)

P(B) = 0.11 (the probability that the flight will be delayed)

P(not A and not B) = 0.88 (the probability that it will not rain and the flight will leave on time)

We can use the complement rule to find P(A or B):

P(A or B) = 1 - P(not A and not B)

P(A or B) = 1 - 0.88

P(A or B) = 0.12

Now we can use the formula for the intersection of two events:

P(A and B) = P(A) × P(B|A)

We know that P(A) = 0.1, and we need to find P(B|A), the probability of the flight being delayed given that it is raining.

We can use Bayes' theorem to find P(B|A):

P(B|A) = P(A and B) / P(A)

P(B|A) = (P(A) × P(B|A)) / P(A)

P(B|A) = P(B and A) / P(A)

We can rearrange this to get:

P(A and B) = P(B|A) × P(A)

Substituting the values we know:

P(B|A) = P(A and B) / P(A)

0.11 = P(A and B) / 0.1

P(A and B) = 0.11 × 0.1

P(A and B) = 0.011

Therefore, the probability that it is raining and the flight is delayed is 0.011, or approximately 0.011 rounded to the nearest thousandth.

Answer:

x = 9

Step-by-step explanation:

To solve the equation 2x - 7 + 3x = 4x + 2 for x, you can follow these steps:

Combine like terms on both sides of the equation. Add the x terms together and move the constant terms to one side of the equation:

2x + 3x - 4x = 2 + 7

Simplifying the left side: x = 9

Simplify the right side of the equation:

x = 9

Therefore, the solution to the equation is x = 9.

Option (c)

\(6 \: units\)

Step-by-step explanation:

By the give problem,

Let

\((x {}{1} ,y1) = ( - 5, - 2)\)

\((x2,y2) = ( - 5, - 8)\)

By using distance formula

\(d = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } \)

\(d = \sqrt{ {( - 5 - ( - 5))}^{2} + {( - 8 - ( - 2))}^{2} } \)

\(d = \sqrt{ { (- 5 + 5)}^{2} + {( - 8 + 2)}^{2} } \)

\(d = \sqrt{0 + 36} \)

\(d = \sqrt{36} \)

\(d = 6 \: units\)

Hence, option (c) is correct

The possible values for a third quiz score that would give her an average between 85 and 90, inclusive is: 97 ≤ x ≤ 112.

In Mathematics, the average of these quiz scores can be calculated by using the following formula:

Average = Sum of quiz score/Number of quiz scores

Note: Let the variable q represent the student's score on the third (3rd) quiz.

Substituting the given parameters into the formula, we have the following;

Average = (75 + 83 + q)/3

Average = (158 + q)/3

This ultimately implies that, an average between 85 and 90, inclusive is given by this compound inequality:

85 ≤ (158 + q)/3 ≤ 90

Multiplying all through by 3, we have the following:

255 ≤ (158 + q) ≤ 270

Subtracting 158 from both sides of the inequality, we have the following:

97 ≤ x ≤ 112

This can be solved using permutations

What are permutations?

A permutation of a set in mathematics is a loosely defined organization of its members into a sequence or linear order, or, if the set is already sorted, a rearranging of its elements. The act or process of shifting the linear order of an ordered set is often referred to as "permutation." Permutations are distinct from combinations, which are random picks of certain members of a collection. For example, there are six permutations of the set 1, 2, 3 represented as tuples: (1, 2, 3), (1, 3, 2), (2, 1, 3), (2, 3, 1), (3, 1, 2), and (3, 1, 2). (3, 2, 1).
