The first two numbers in each row of the relative frequency table represent the percentage of cars and trucks of a particular color out of the total number of vehicles in the parking lot.

To create a relative frequency table, we need to divide the frequency of each color by the total number of vehicles (65) and then multiply by 100 to get a percentage.

Relative Frequency Table by Color:

The first two numbers in each row must add up to 100% because we are calculating the relative frequency of each color with respect to the total number of vehicles (65). Therefore, the percentage of cars and trucks of each color must add up to 100% of that color's total frequency. The total row must also add up to 100% because it represents the entire population of vehicles.

Answer:

c  (2,0)

Step-by-step explanation:

One way to solve this system of inequalities is to graph the inequalities and see which ordered pair lies in the shaded region that is common to both inequalities

See the graph and each of the ordered pairs. Only (2, 0) lies entirely within the shaded region

(-1, 0) lies on the intersection of the two lines so it will satisfy the >= inequality but not the < inequality

Answer (2, 0)

However if you cannot use graphing then a brute force method must be used to see which ordered pair satisfies both inequalities

a. (-1, 0)
Check y < 2x + 2 ?
=>  0 < 2(-1) + 2 ?
=> 0 < -2 + 2
0 < 0 ? False
Eliminate option a

b. (0, 3)
y < 2x + 2?
=> 3 < 2(0) + 2?
3 < 2? False
Eliminate option b

c. (2, 0)
y < 2x + 2?
=> 0 < 2(2) + 2 ?
=>  0 < 4 + 2
=> 0 < 6 True

Move to the second inequality
y ≥ -x - 1?
0 ≥ -2 - 1
0 ≥ -3 True

So option c is the correct choice

While it is not necessary to check option d, let's do it anyway
d. (-1, -4)
y < 2x + 2 ?
-4 < 2(-1) + 2 ?
-4 < -2 + 2 ?
-4 < 0 ? True

Move to the second inequality
y > -x - 1 ?
-4 > -(-1) - 1
-4 > -2? False
Option d is eliminated

Correct answer: (2, 0) which is option c

the first one is C

the second one is D

the third one is B

and the last one is A

All you want to do is count up the y-intercept when it crosses and that gives you the last number (b).

Slope of lines 3x - 5y = 2 and 3x + 5y = -2 are m₁ = 3/5 and m₂ = -3/5 respectively.

The slope of a line is defined as the change in y-coordinate with respect to the change in x-coordinate of the line. The net change in the y coordinate is Δy and the net change in the x coordinate is Δx. Therefore, the change in y-coordinate for a change in x-coordinate can be written as

Line slope is a measure of the steepness or direction of a line in the coordinate plane.  

m = Δy/Δx

where,m is the slope

Given,

equations of the line

3x - 5y = 2

Moving 3x to RHS
-5y = -3x + 2

y = (3/5)x - 2/5

comparing with slope intercept equation of the line y = mx + c

slope m₁ = 3/5

Now, equation

3x + 5y = -2

moving 3x to RHS

5y = -3x - 2

y = (-3/5)x - 2

comparing with slope intercept equation of the line y = mx + c

slope m₂ = -3/5

Hence, m₁ = 3/5 and m₂ = -3/5 are slope of lines 3x - 5y = 2 and 3x + 5y = -2 respectively.

Step-by-step explanation:

It will take Rick 15 weeks to reach his target weight of 175 pounds.

Let "w" represent the number of weeks it will take for Rick to reach his target weight.

The rate at which Rick is losing weight is 2 pounds per week, so the amount of weight he will lose in "w" weeks can be represented as 2w.

The equation to represent the weight loss can be written as 205 - 2w = 175, where 205 is Rick's current weight and 175 is his target weight.

Solving the equation, we subtract 205 from both sides and divide by 2: -2w = -30, w = 15.

Answer:

  f(x) = (3x -2)(2x +1)

Step-by-step explanation:

The procedure for factoring expression of the form ...

  ax² +bx +c

is to look for factors of a·c that have a sum of b.

The product a·c is 6·(-2) = -12. You are looking for factors that have a sum of b = -1. From your familiarity with multiplication tables, you know ...

  -12 = 1(-12) = 2(-6) = 3(-4)

The sums of the factor pairs in this list are -11, -4, -1. So, the last pair of factors, {3, -4} is the one we're looking for.

__

At this point, there are several ways to proceed. Perhaps the simplest is to rewrite the linear term as the sum of terms involving these factors:

  -x = 3x -4x

  f(x) = 6x² +3x -4x -2

Now, the expression can be factored 2 terms at a time:

  f(x) = (6x² +3x) -(4x +2) . . . . . pay attention to signs

  f(x) = 3x(2x +1) -2(2x +1) . . . . factor each pair

  f(x) = (3x -2)(2x +1) . . . . . . . . factor out the common factor of (2x+1)

A property of the exponential distribution is that the mean equals the standard deviation.

The exponential distribution is a probability distribution that models the time between successive events in a Poisson process, where events occur continuously and independently at a constant rate.

The probability density function of the exponential distribution is given by:

f(x) = λe⁻ˣ, for x ≥ 0

where λ is the rate parameter, which represents the average number of events per unit time.

The mean of the exponential distribution is given by:

μ = 1/λ

The variance of the exponential distribution is given by:

σ² = 1/λ²

The standard deviation of the exponential distribution is the square root of the variance:

σ = 1/λ

Therefore, we can see that the mean and standard deviation of the exponential distribution are equal:

μ = σ = 1/λ

This property is a consequence of the fact that the exponential distribution is a memoryless distribution, which means that the probability of an event occurring within a certain time interval does not depend on how much time has already elapsed. This property also makes the exponential distribution useful in modeling waiting times and failure times.

Hence, A property of the exponential distribution is that the mean equals the standard deviation.

What is algebra ?

Algebra is a branch of mathematics in which letters and symbols are used to represent numbers and quantities in equations and formulas. Algebraic concepts include operations such as addition, subtraction, multiplication, and division, as well as the manipulation of equations

The maximum likelihood estimate (MLE) for p is the value that maximizes the likelihood function, which represents the probability of observing a particular sequence of red and white chips given the assumed distribution of reds and whites. In this case, we have two options for the proportion of reds, either 1/3 or 1/2. To calculate the likelihood of observing the sequence red, white, white, red, and white given p = 1/3, we calculate (1/3)(2/3)(2/3)(1/3)(2/3) = 4/243. To calculate the likelihood of observing the sequence given p = 1/2, we calculate (1/2)(1/2)(1/2)(1/2)(1/2) = 1/32. As we can see, the maximum likelihood estimate for p is 1/2, as the likelihood of observing this sequence given p = 1/2 is greater than the likelihood of observing this sequence given p = 1/3.

Answer:

It is not an arithmetic sequence.

Step-by-step explanation:

In an arithmetic sequence, the differences between any two consecutive terms are equal.

7 - 6 = 1

9 - 7 = 2

The differences between two different sets of consecutive terms are different, so it is not an arithmetic sequence.

Answer:

Step-by-step explanation:

For a sequence to be "arithmetic," there must be a common difference from one term to the next.  6,7,9,10,12...  does not live up to this criterion:

from 6 to 7 is 1

from 7 to 9 is 2

from 9 to 10 is 1

from 10 to 12 is 2

If the sequence were 6, 7, 8, 9, 10, the sequence would be "arithmetic," with a common difference of 1.

Answer:B

Step-by-step explanation:

The equivalent expression is 8.

Option B is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

\((16^{3/2})^{1/2}\)

This can be written as,

= \(16^{3/2 \times 1/2}\)

= \(16^{3/4}\) ______(1)

Now,

16 = \(2^4\) ______(2)
