What is Linear Equation?

A linear equation is a mathematical expression in which the highest power of the variable is 1. It can be written in the form of:

y = mx + b

where y and x are variables, m is the slope of the line, and b is the y-intercept of the line. This form is called the slope-intercept form of a linear equation.

To solve the equation 6x + 16 = 2x + 28:

Simplify both sides of the equation by combining like terms:

6x + 16 = 2x + 28

Subtract 2x from both sides:

4x + 16 = 28

Subtract 16 from both sides:

4x = 12

Solve for x by dividing both sides by 4:

4x = 12

x = 3

Therefore, the solution to the equation 6x + 16 = 2x + 28 is x = 3.

Answer:

x = 3/85

Step-by-step explanation:

log2 (6) - log2 (5x) = log2 ( 34)

We can use the properties of logs.

First subtract log2 (6) from each side.

log2 (6) - log2 (5x) - log2 (6) = log2 ( 34)-log2 (6)

- log2 (5x)  = log2 ( 34)-log2 (6)

Now we know that log a - log b = log a/b

- log2 (5x)  = log2 ( 34/6)

- log2 (5x)  = log2 ( 17/3)

Multiply each side by -1

 log2 (5x)  = -log2 ( 17/3)

We know that  -log (a/b) = log ( b/a)

 log2 (5x)  = log2 ( 3/17)

The terms inside the logs must be the same

5x = 3/17

Divide each side by 5

5x/5 = 3/17 * 1/5

x = 3/85

Speed of Ana =  7.5miles/hour

Step-by-step explanation:

Given,

Ana runs 3/4 mile in 6 minutes.

To find,

The speed of Ana in miles per hour

Recall the formula,

Speed = distance travelled/time taken

60 minutes = 1 hour

Solution:

Distance traveled = 3/4 mile

Time taken = 6 minutes

Since 60 minutes = 1 hour, we have

1 minute =1/60 hour

6 minutes = 6/60 hour

=1/10  hour

Hence speed  = distance travelled/time taken

=  3/4 / 1/10 miles/hour

= 15/2 miles/hour

= 7.5miles/hour

∴ Speed of Ana =  7.5miles/hour

The given question is incomplete, the complete question is :

if you were to graph a sine function from the data listed in the table above, what values would be represented by the dependent variable and what would be represented by the independent variable?

(i) none of these ailments, 26

(ii) arthritis but neither of the other two ailments, 17

(iii) exactly one of these ailments, 102

(iv) arteriosclerosis and loss of hearing but not arthritis, 16

We can use a Venn diagram to solve this problem.

Let A, B, and C represent the events of having arthritis, arteriosclerosis, and loss of hearing, respectively. Then, the given information can be represented as:

A = 70

B = 60

C = 80

A ∩ B = 35

A ∩ C = 33

B ∩ C = 31

A ∩ B ∩ C = 15

Using these values, we can find the answers to the questions:

(i) The number of senior citizens with none of these ailments is the complement of the union of A, B, and C. That is:

n(A ∪ B ∪ C)' = n(S) - n(A ∪ B ∪ C)

                      = 200 - (70 + 60 + 80 - 35 - 33 - 31 + 15)

                      = 26

Therefore, 26 senior citizens had none of these ailments.

(ii) The number of senior citizens with arthritis but neither of the other two ailments is:

n(A) - n(A ∩ B) - n(A ∩ C) + n(A ∩ B ∩ C)' = 70 - 35 - 33 + 15

                                                                   = 17

Therefore, 17 senior citizens had arthritis but neither of the other two ailments.

(iii) The number of senior citizens with exactly one of these ailments is the sum of the complements of the intersections of the events. That is:

n(A' ∩ B ∩ C') + n(A ∩ B' ∩ C') + n(A' ∩ B' ∩ C) = (200 - 60 - 31 - 15 - 33) + (200 - 70 - 31 - 15 - 33) + (200 - 70 - 60 - 15 - 35) = 102

Therefore, 102 senior citizens had exactly one of these ailments.

(iv) The number of senior citizens with arteriosclerosis and loss of hearing but not arthritis is:

n(B ∩ C) - n(A ∩ B ∩ C) = 31 - 15 = 16

Therefore, 16 senior citizens had arteriosclerosis and loss of hearing but not arthritis.

Answer:

Step-by-step explanation:

The total cost for Nayeli to enter the amusement park is $40. If she goes on 9 rides, the cost for the rides would be 9 * $2 = $18. Therefore, the total cost for Nayeli to enter the park and go on 9 rides would be $40 + $18 = $58.

To find the total cost if she goes on r rides, we can use the formula:

Total cost = $40 + r * $2

So, if Nayeli goes on r rides, she would have to pay $40 + r * $2 in total.

To calculate the total cost, multiply the number of rides by the cost per ride and add it to the admission price.

To calculate the total amount Nayeli would have to pay if she goes on 9 rides, we need to first calculate the cost of admission. The admission price is $40. Then, we multiply the number of rides (9) by the cost per ride ($2) and add it to the admission price to get the total cost.
Total cost = Admission price + (Number of rides x Cost per ride) = $40 + (9 x $2) = $40 + $18 = $58.
If Nayeli goes on 'r' rides, we can use the same formula to calculate the total cost. The total cost would be the admission price ($40) plus the product of the number of rides ('r') and the cost per ride ($2). Total cost = $40 + (r x $2) = $40 + $2r.

The median should be used to describe a normal or skewed distribution, as it is a better measure of the central tendency than the mean for these types of distributions.

The median is a better measure of the central tendency than the mean when describing a normal or skewed distribution. A normal distribution is a symmetrical distribution of data in which values are evenly spread around the mean. A skewed distribution is when one side of the distribution is longer than the other, with the mean being pulled away from the center. The median is the most appropriate measure of central tendency for both normal and skewed distributions because the mean can be distorted by outliers and extremes in the data. The median is the midpoint in the data and provides a better representation of the middle of the distribution, which can be useful in interpreting the data. Using the median to describe a large distribution or percentage is not as common as it is better to use the mean or mode for these types of distributions.

50 must have been his starting number of cherries.

Seb had 50 cherries at the start. This can be determined by solving the equation 10x + 5 = 40, where x is the number of days he ate 10 cherries and gave 5 away. When you solve the equation, you get x = 5, meaning he did this 5 times. Since 10x is 50, and 5 is added to that, the total is 50. Therefore, Seb had 50 cherries at the start.

To solve the equation, you first need to subtract 5 from both sides to get 10x = 35. Then, divide both sides by 10 to get x = 3.5. Since Seb could not have eaten 3.5 days worth of cherries, it means that he did the 10 and 5 activity 4 times, giving him 40 cherries before giving away the last 5. So 40 + 5 = 45 and 10x = 50, so 50 must have been his starting number of cherries.

The probability that the bird feeder will be visited by more than 5 birds in a 40 minute period during daylight hours is 0.835.

In the question Justin has a bird feeder which gets visited by an average of 18 birds every 2 hours during daylight hours and we have to find what is the probability that the bird feeder will be visited by more than 5 birds in a 40 minute period during daylight hours.

This can be calculated using the Poisson distribution formula, P(X > 5) = 1 - P(X ≤ 5).

P(X > 5) = 1 - P(X ≤ 5)

= 1 - (P(X=0) + P(X=1) + P(X=2) + P(X=3) + P(X=4) + P(X=5))

= 1 - (0.0022 + 0.0133 + 0.0514 + 0.1245 + 0.2141 + 0.2769)

= 0.8351

The inequality that represents this situation is y - 2x > 16.

Let's start by finding Terry's current winning percentage:

Terry's current winning percentage = 18/35 = 0.5143 (rounded to 4 decimal places)

We want to find out how many of the remaining games Terry needs to win for her winning percentage to be greater than Sandra's winning percentage, given that Sandra doesn't win any more games. Sandra's current winning percentage is:

Sandra's current winning percentage = 24/36 = 0.6667 (rounded to 4 decimal places)

Let x be the number of remaining games and y be the number of games Terry needs to win. Since there are a total of x remaining games and Terry wins y of them, she will have won a total of 18 + y games out of 35 + x games. Therefore, her winning percentage after winning y of the remaining games would be:

(18 + y) / (35 + x)

We want this winning percentage to be greater than Sandra's winning percentage:

(18 + y) / (35 + x) > 24/36

Multiplying both sides by 36(35 + x), we get:

36(18 + y) > 24(35 + x)

Simplifying the left-hand side:

36(18 + y) = 648 + 36y

Simplifying the right-hand side:

24(35 + x) = 840 + 24x

Substituting these simplifications back into the inequality, we get:

648 + 36y > 840 + 24x

Simplifying:

12y - 24x > 192

Dividing both sides by 12:

y - 2x > 16

Therefore, the inequality that represents this situation is:

y - 2x > 16

So Terry needs to win more than twice as many remaining games as the number of games Sandra has won more than her in order to have a winning percentage greater than Sandra's winning percentage.

Answer:

I suppose she also paid $100 because a 20% off from Thiago could mean that the original price was 120.

Step-by-step explanation:

The average rate of change of R(t) over the time intervals [t, t + h] , where t is as indicated and h = 1, 0.1, and 0.01 are 210,100 and 100.

What is Differentiation?

Finding a function's derivative, or rate of change, is the process of differentiation in mathematics. The practical approach of differentiation can be performed utilising only algebraic operations, three fundamental derivatives, four principles of operation, and an understanding of how to manipulate functions, in contrast to the theory's abstract character.

Given function :  R(t) = 240 + 30t^3

  R'(t) = 90 t²

So, the average rate of change of R(t) is 90 t² .

Now, over the time interval [t, t + h], it will be as follows:

we know that, f'(t) = {f(t+h) - f(t)} / h

So, when h = 1,  f'(1) = {f(1+1) - f(1)} / 1

                                = f(2) - f(1)

                                = 480 - 270 = 210

when h = 0.1 , f'(1) = {f(1+0.1) - f(1)} / 0.1

                             = {f(1.1) - f(1)} / 0.1

                             = (280 - 270) / 0.1 = 100

when h = 0.01 , f'(1) = {f(1+0.01) - f(1)} / 0.01

                                 = {f(1.01) - f(1)} /0.01

                                 = (271 - 270) / 0.01 = 100
