The proportions for this problem are given as follows:

a) Took echinacea: 0.27.

b) Having a cold in the last 30 days, of those who took Vitamin C: 0.2679.

c) Took zinc, of those having a cold: 0.1923.

The proportions are calculated as the division of the number of desired outcomes by the number of total outcomes.

The survey is composed by 100 adults, and of those, 27 took echinacea, hence the proportion is of:

27/100 = 0.27.

56 adults took vitamin C, and of those, 15 reported a cold in the last 30 days, hence the proportion is of:

15/56 = 0.2679.

26 students had a cold in the last 30 days, and of those, 5 took zinc, hence the proportion is calculated as follows:

The reasonable estimate of the probability that Todd runs 5/13.

We know that,

Experimental probability = Number of favorable outcomes/total number  of outcomes.

Experimental probability, also called empirical probability, is based on real experiments and rational records of what happened. A series of real-world experiments are conducted to determine the occurrence of events. Experiments with undetermined results are called random experiments. The results of such experiments are uncertain. Repeat the random experiment several times to determine its probability. Experiments are repeated a specified number of times, and each repetition is called a trial. Mathematically, the formula for experimental probability is defined as:

Probability of event P(E) =

frequency of occurrence of event / total number of trials.

According to the question:

The number of favorable outcomes are 5.

The total number of outcomes are 2 + 3 + 3 + 5 = 13.

Therefore, the reasonable estimate of the probability that Todd runs is 5/13.

Answer:

Below

Step-by-step explanation:

A line with slope = 0 is a horizontal line

 for y = mx + b form this would be

   y = (0)* x  + 10

   y = 10

Explanation:

If the corresponding angles 5x+15 and 115 are congruent, then line 'a' is parallel to line 'b'.

5x+15 = 115

5x = 115-15

5x = 100

x = 100/5

Answer:

Landon would have -$43.53 in his checking account after the check is cashed and the bank handles his overdraft.

Step-by-step explanation:

The unknown angle in the intersecting lines is as follows:

m∠2 = 20 degrees

In the figure m∠ABD is 100 degrees and m∠1 is four times m∠2. Therefore, let's find the angle m∠2.

From the diagram, the sum of angle ABC and angle CBD is equals to angle ABD.

Therefore,

m∠ABD = 100 degrees

m∠ABC = m∠2

m∠CBD = m∠1

Therefore,

let

x = m∠2

m∠1 = 4x

Hence,

100 = 4x + x

5x = 100

divide both sides by 5

x = 100 / 5

x = 20 degrees

Therefore,

m∠2 = 20 degrees

The equation of the line that passes through point (8, -7) and parallel to the line x + 2y = 18 is

A linear function consists of functions where the variables has exponents of 1.

The graph of linear functions is a straight line graph and the relationship is expressed in the form.

y = mx + c

definition of variable

y = output variable

m = slope

x = input variable

c = y intercept

x + 2y = 18

rewriting gives : y = -x/2 + 9

when the line is parallel the slope is equal hence the slope of the line is -1/2.

using the point slope formula for point (8, -7) which is

(y - y') = m(x - x')

(y + 7) = -1/2(x - 8)

y + 7 = -x/2 + 4

y = -x/2 - 3

the equation of the line is y = -x/2 - 3

The point at which  =the curve xy = 25 is the tangent line parallel to 5x + y = 0 is y = ± 5√5 so, option A is correct.

A simple line in Euclidean geometry. A line, according to Euclid, is the distance between two points and can stretch forever in either direction. While Euclid's initial definition is now regarded as a line segment, such an extension in both directions is now thought of as a line.

Given:

the curve xy = 25 and the equation of the line is 5x + y = 0,

The equation of line  parallel to line 5x + y = 0 will be,

y = mx + c

y = -5x + c   (y = -5x)

The line will be in the curve as it is tangent, so,

Answer:

The man made a profit of 63.333% from selling the machine.

Step-by-step explanation:

To find the percentage profit, you will need to first calculate the total profit the man made from selling the machine. To do this, you need to subtract the cost of importing the machine and the other costs associated with clearing and shipping it from the selling price.

Here's the calculation:

Total profit = Selling price - (Import cost + Clearing cost + Shipping cost)Substituting the values you provided, we get:Total profit = 1,080,000 - (600,000 + 60,000 + 40,000)

Total profit = 1,080,000 - 700,000Total profit = 380,000

Next, we need to divide the total profit by the import cost, and multiply the result by 100 to express the profit as a percentage. Here's the calculation:

Percentage profit = (Total profit / Import cost) * 100Substituting the values we calculated above, we get:Percentage profit = (380,000 / 600,000) * 100Percentage profit = 63.333%

Therefore, the man made a profit of 63.333% from selling the machine.
