In this dissertation about the insect Desmolithica Geogebra, the searching period S(t) of the insect depends on the air temperature denoted by t and is directly proportional to t-20.

The percentage of the larvae that survive this period N(t) is inversely proportional to t-20 and depends on t.

These statements can be mathematically represented as:

S(t) ∝ (t - 20)

and

N(t) ∝ 1/(t - 20)

For S(t) and N(t) to be directly and inversely proportional to (t - 20), respectively, we need to assume that the relationship is linear.

That is, S(t) and N(t) can be represented by linear equations of the form:

S(t) = m(t - 20)

and

N(t) = k/(t - 20)

where m and k are constants that depend on the particular observation regarding the behavior of the insect.

These constants can be determined by using the data from the observations.

The dissertation can further explain the significance of these relationships in understanding the behavior of the insect, as well as in developing strategies to control or prevent the damage caused by the insect.

a. The number of teenagers that like hard rock is of: 272.

b. The number of teenagers surveyed is of: 200.

c. A percentage greater than 100% is when the percentage of an amount is calculated relative to an smaller amount.

The measures are obtained applying the given proportions and percentages in the context of the problem.

For item a, the amount is of 32% of 850, hence:

0.32 x 850 = 272 teenagers like hard rock.

For item b, we have that 75% = 0.75 of the amount x is of 150, hence the total amount of teenagers surveyed is obtained as follows:

0.75x = 150

x = 150/0.75

x = 200 teenagers were surveyed.

A percentage is calculated as the division of an amount a by an amount b. Hence, if the amount a is greater than the amount b, the percentage will be greater than 100%.

Morals are frequently seen as standards of conduct that originate within the individual.

Morals refer to personal beliefs and values that guide an individual's behavior and decision-making. They are often influenced by cultural, social, and religious factors and can vary among individuals. Morals provide a framework for distinguishing right from wrong and can shape an individual's sense of integrity and responsibility. Unlike external standards or ethical frameworks imposed by society or institutions, morals are internalized by individuals and serve as a basis for their ethical judgments and actions.

The coordinates of midpoint D from the given triangle ABC is (-4x, 0).

A midpoint of a line segment is the point on a segment that bisects the segment into two congruent segments.

The formula to find the midpoint of line segment is (x, y) = [(x1+x2)/2, (y1+y2)/2]

From the given figure, the coordinates are A(-6x, 4y) and B(-2x, -4y) and C(8x, -2y)

By unitary method,

for a basic contract the cost of 7 hours of calls at standard hours would be,

7 * 6 = $42

So, the total cost would be,

the probability that a randomly selected person from this group is moderate, given they have only a high school education, is approximately 23%.

To find the probability that a randomly selected person from this group is moderate, given they have only a high school education, we need to use conditional probability.

Let's denote the event "moderate" as M and the event "high school only" as H. We want to find P(M|H), which represents the probability of being moderate given that the person has only a high school education.

From the table, we can see that there are 17 people who are moderate and have only a high school education, and there are a total of 74 people who have only a high school education. Therefore:

P(M|H) = P(M and H) / P(H)

where P(M and H) represents the probability of being moderate and having only a high school education, and P(H) represents the probability of having only a high school education.

From the table, we can see that:

P(M and H) = 17/100

P(H) = 74/100

Therefore:

P(M|H) = (17/100) / (74/100)

P(M|H) = 0.2297 or approximately 23%

I'm assuming this is a right triangular prism.

The area of the two triangles at the front and back of the figure are (1/2)(10)(26), so the sum of their areas is (10)(26)=260.

The area of the back rectangle is 36(10)=360.

The area of the top rectangular face is (36)(28)=1008.

And finally, the area of the bottom rectangular face is (36)(26)=936.

So the total surface area is 1008 + 936 + 360 + 260 = 2564.

The probability that all four piles have exactly one Ace is 1 / (13 * 17 * 50 * 49), which is approximately 0.00014424.

To find the probability that all four piles have exactly one Ace, we can consider the number of ways to distribute the Aces and the total number of possible distributions.

There are 4 Aces in the deck, and each pile should receive exactly one Ace. The first Ace can be placed in any of the 52 cards, the second Ace in any of the remaining 51 cards, the third Ace in any of the remaining 50 cards, and the fourth Ace in any of the remaining 49 cards.

So, the total number of possible distributions is 52 * 51 * 50 * 49.

To calculate the probability, we need to divide the number of favorable outcomes (where all piles have exactly one Ace) by the total number of possible distributions.

Since each Ace can be distributed to any of the 4 piles, the number of favorable outcomes is 4 * 3 * 2 * 1.

Therefore, the probability is (4 * 3 * 2 * 1) / (52 * 51 * 50 * 49), which simplifies to 1 / (13 * 17 * 50 * 49).

Answer:

Then 1/2 or  30 minutes is the required time for Tom to cover the exact distance that Linda one hour before.

Two hours after Tom began Tom would cover 12 miles and three hours after Linda started Linda would be 6 miles far away from the starting point

Step-by-step explanation:

Linda walks in a straight line at 2 miles/hour

then after t ( hours time) she is    2 (m/h) * t   = d (L)

for Tom running at 6 m/h starting one hour later to cover the same distance d(L)

d(L)  =  6 m/h * ( t - 1 )    then:

2 (m/h) * t   =   6 m/h * ( t - 1 )

2*t  =  6*t - 6

4*t = 6

t = 6/4

t =  1,5 h

Checking that result.

we see that in 1,5 hours Linda has covered  2* 1,5  = 3 miles

and  in 0.5 hours  Tom covered the same distance  0,5 * 6 = 3 miles

NOTE: Remember that tom started one hour later.

Then 1/2 or  30 minutes is the required time for Tom to cover the exact distance that Linda one hour before.

b)  In this case

d(T) = 6* ( t - 1 )       must be equal  to  twice of the Linda distance

d(L)  = 2 * 2 * t

6*t - 6  =  4*t

2*t  =  6

t  = 3

To check it

in 3 hours   Linda had covered  3 * 2  =  6 miles

in 2 hours   Tom had covered   2 * 6  =  12 miles

Out of the 500 people surveyed, we would expect approximately 155 of them to consider reading books or surfing the Internet as the best entertainment value.

To calculate the expected number of people who considered reading books or surfing the Internet as the best entertainment value out of the 500 surveyed, we need to calculate the percentage corresponding to reading books and surfing the Internet.

The percentage for reading books is 22% and the percentage for surfing the Internet is 9%. To find the combined percentage, we add these two percentages:

22% + 9% = 31%

Now, we can calculate the expected number by multiplying the combined percentage by the total number of people surveyed:

Expected number = 31% of 500 = (31/100) * 500 = 155

The complete question is:

Out of 500 people surveyed, how many would you expect considered reading books or surfing the Internet as the best entertainment value?
