The graph that shows the relationship given in the table is the one with the x-axis labeled as "Time in days," the y-axis labeled as "Number of boxes," and a line passing through the points (0, 23) and (2, 17). Option A

To determine which graph shows the relationship given in the table, we need to find the line that passes through the given points.

The table provides the following data points:

Time (days): 1, 3, 4, 7

Number of Boxes: 23, 17, 14, 5

We can now examine the given options:

Option 1: A line passing through the points (0, 23) and (2, 17)

If we plot these points on a coordinate plane with the x-axis labeled as "Time in days" and the y-axis labeled as "Number of boxes," we can draw a line connecting the two points.

Option 2: A line passing through the points (0, 23) and (2, 11)

Similarly, we plot these points and draw a line connecting them.

Option 3: A line passing through the points (0, 26) and (2, 20)

We plot these points and draw a line connecting them.

Option 4: A line passing through the points (0, 26) and (2, 14)

We plot these points and draw a line connecting them.

To determine the correct option, we compare the plotted lines with the data points given in the table.

Answer:

no of child tickets sold were 58

Step-by-step explanation:

Let the number of child ticket sold be x

cost of 1 child ticket = $6.10

Total cost of x child ticket = x*cost of 1 child ticket = = $6.10x

Let the number of adult ticket sold be y

cost of 1 adult ticket = $9.90

Total cost of y adult ticket = y*cost of 1 adult ticket = = $9.90y

Given total ticket sold = 142

Thus,

number of child ticket sold +  number of adult ticket sold = 142

x + y = 142   - equation 1

x = 142 -y  

Total sales of ticket = $1185.40

total sales of ticket  = Total cost of x child ticket + Total cost of x a dult ticket

6.10x + 9.90y = 1185.40

in this equation substituting x = 142 - y from equation 1

6.10(142 - y )  + 9.90y = 1185.40

=>866.2 - 6.10y + 9.90y = 1185.40

=> 3.80y = 1185.40 - 866.2

=> 3.80y = 319.2

=> y = 319.2/3.80 = 84

Thus, y = 84

x = 142 - y  = 142 - 84 = 58

Thus, no of child tickets sold were 58

===========================================================

Explanation:

Add up the numbers in the second column:

4+19+25+32 = 80

There are 80 people being surveyed in the table.

Of those 80 people surveyed, 32 of them exercised for more than 136 minutes.

The probability of selecting someone who exercised for more than 136 minutes is the fraction 32/80 = (16*2)/(16*5) = 2/5

----------

Multiply this probability with the larger sample size of 300 to get

(2/5)*300 = 0.4*300 = 120

We estimate that 120 people would exercise for more than 136 minutes.

Note that 120/300 = 2/5.

Given an arithmetic sequence with a common difference of 3 and the tenth term being 11, we can find the sum of the first 30 terms. The sum is 810.

In an arithmetic sequence, each term is obtained by adding a constant value, called the common difference, to the previous term. Let's denote the first term of the sequence as 'a' and the common difference as 'd'.

Given that the tenth term is 11 and the common difference is 3, we can use this information to find the first term. We know that the tenth term is obtained by adding the common difference 9 times to the first term:

a + 9d = 11

Substituting the value of the common difference (d = 3), we can solve for 'a':

a + 9(3) = 11

a + 27 = 11

a = 11 - 27

a = -16

Now that we have the first term 'a' and the common difference 'd', we can find the sum of the first 30 terms using the formula for the sum of an arithmetic series:

S = (n/2)(2a + (n-1)d)

Here, 'n' represents the number of terms. Substituting the values, we have:

S = (30/2)(2(-16) + (30-1)(3))

S = 15(-32 + 29(3))

S = 15(-32 + 87)

S = 15(55)

S = 825

Therefore, the sum of the first 30 terms of the given arithmetic sequence is 810.

In the given normal distribution with a mean of 100 and standard distribution of 15, 95% of values will fall between 70 and 130 using the Empirical rule of 95%.

It states that in a normal distribution approximately 95% of observations fall within two standard deviations from the mean on both sides of the normal curve. The normal curve's centre corresponds to the mean in a normal distribution.

The distance between the mean and the necessary point on either side in a normal distribution is known as the standard deviation.

Given: Mean = 100

Standard deviation = 15

Apply the 95% rule we get,

The normal curve's right side

Mean + 2 x standard deviation

= 100 + 2x 15

= 100 + 30

= 130.

The normal curve's left side,

Mean - 2 x standard deviation  

= 100 - 2x15

= 100 - 30

= 70.

Thus, we see that by using the Empirical rule of 95%, 95% values will fall between 70 and 130.

(- 1, 3 )

Step-by-step explanation:

2x + 3y = 7 → (1)

- 2x + 4y = 14 → (2)

add (1) and (2) term by term to eliminate x

(2x - 2x) + (3y + 4y) = (7 + 14)

0 + 7y = 21

7y = 21 ( divide both sides by 7 )

y = 3

substitute y = 3 into either of the 2 equations and solve for x

substituting into (1)

2x + 3(3) = 7

2x + 9 = 7 ( subtract 9 from both sides )

2x = - 2 ( divide both sides by 2 )

x = - 1

As a check

substitute the values of x and y into the left side of both equations and if equal to the right side in both equations then the values of x and y are true.

(1) 2(- 1) + 3(3) = - 2 + 9 = 7 ← true

The ratio strength of the final product is 1:0.4.

One technique to indicate concentration is through ratio strength, which uses a ratio to characterize drug concentration. In this context, concentration is defined as the quantity of a solute that makes up one unit in the whole volume of a solution or combination. You should be an expert in ratio strength calculations as a pharmacy student. Ratio strength uses a ratio to describe the medication concentration. So, what it implies is, you have one unit of solute contained in the complete amount of preparation and so generally your ratio strength is expressed as one is to something. In the case of a weight-in-weight, volume-in-volume, or weight-in-volume situation, you would interpret a ratio of 1:2,000 differently.

Drug strength = 800mg

The annual maintenance collected in 2014 will be $1,750,000.

To calculate the annual maintenance collected in 2014, we need to find the number of customers who will renew their maintenance contract and the number of customers who will pay for maintenance as a percentage of product sales in 2013.

Number of customers renewing maintenance in 2014 = 80% of $2,000,000 = $1,600,000

Number of customers paying for maintenance in 2014 = 75% of $2,000,000 = $1,500,000

So, the total annual maintenance collected in 2014 will be:

$1,600,000 + $1,500,000*10% = $1,750,000

The dimensions of the fencing that will minimize the cost of the fence are 50 feet by 100 feet.

The area of the total lot with all three pens is 5000 square feet, which means that the total area of the fencing is also 5000 square feet.

Let's say the length of the fencing is x feet and the width of the fencing is y feet. We can write the following equation to represent the area of the fencing:

xy = 5000

The cost of the horizontal fencing (length) is $26 per foot, so the total cost of the horizontal fencing is 26x. The cost of the vertical fencing (width) is $12 per foot, so the total cost of the vertical fencing is 12y. The total cost of the fencing is the sum of these two costs, so we can write the following equation to represent the total cost of the fencing:

26x + 12y = C

Where C is the total cost of the fencing.

We want to minimize the total cost of the fencing, so we want to find the values of x and y that minimize the value of C We can do this by setting up a system of equations and solving for x and y.

xy = 5000

26x + 12y = C

We can solve this system of equations using the substitution method. First, we can solve the first equation for y:

\($y = \frac{5000}{x}$\)

Substituting this expression for y into the second equation, we get:

\($26x + 12(\frac{5000}{x}) = C$\)

Solving for x, we get:

\($x = \sqrt{625} = 25$\)

Substituting this value for x into the first equation, we get:

\($y = \frac{5000}{25} = 200$\)

Therefore, the dimensions of the fencing that will minimize the cost of the fence are x = 25 feet and y = 200 feet, which is a fencing with a length of 50 feet and a width of 100 feet.
