Answers

Answer:

a. s = [tex]\frac{d}{t}[/tex]

b. 9600 ft

Step-by-step explanation:

In the given question, the motion of the bee involves speed (s), distance (d) and its time of flight (t).

a. The equation required to determine the distance of the flowerbed from the hive/ hive to flowerbed is;

speed = [tex]\frac{distance}{time}[/tex]

i.e s = [tex]\frac{d}{t}[/tex]

b. Given that: the bee flies back at 8 feet per second, and in 20 minutes (1200 seconds);

s = [tex]\frac{d}{t}[/tex]

⇒ d = s x t

       = 8 ft/s x 1200 s

       = 9600 ft

The flowerbed is 9600 feet from the hive.

Forty discrete math students are to be divided into eight discussion groups, each consisting of five students. In how many ways can this be done?

Answers

There are 65,800,850,944,000 ways to divide the 40 students into 8 discussion groups, each consisting of 5 students.

To find the number of ways to divide 40 students into 8 discussion groups of 5 students each, we'll use a combination formula.

The number of ways to choose 5 students out of 40 for the first group is given by C(40, 5).

After choosing 5 students for the first group, there will be 35 students left for the second group.

The number of ways to choose 5 students out of these 35 for the second group is C(35, 5).

We continue this process until all 8 groups are formed.

The total number of ways to divide the students into groups is the product of the combinations for each group. So, the total number of ways is:

Total ways [tex]=^{40}C_5 \times ^{35}C_5 \times^{30}C_5 \times ^{25}C_5 \times ^{20}C_5 \times ^{15}C_5 \times ^{10}C_5 \times ^{5}C_5[/tex]

Total ways = 65800850944000

Hence, there are 65,800,850,944,000 ways to divide the 40 students into 8 discussion groups, each consisting of 5 students.

A population’s instantaneous growth rate is the rate at which it grows for every instant in time. Function r gives the instantaneous growth rate of a fruit fly population x days after the start of an experiment.

r(x) = 0.05(x^2 + 1)(x - 6)

Consider the graph of function r.

Function r has (blank) and (blank). Based on the instantaneous growth rate, the population decreased (blank) hours and the population increased (blank) hours.

Answers

Answer:

Decreased 4 days-96 hours

Increased 6 days-144 hours

Step-by-step explanation:

In order to solve this you just have to look at the graph and after the start of the experiment which is basically the origin of the graph and as you can see immidiately goes down after the start and it reaches the turning point in the day four which is when the graph starts to go up in the Y axis, so that day it would start the increase, and it increases from day 4 to 10 that would be 6 days, and the decrease would be from the origin to day 4.

B. 46
C. 28
D. 22

Answers

The solution of the given equation √x - 3 + 1 = 6 will be x = 64 so option (A) will be correct.

What is the equation?

An equation can be defined in numerous ways. Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.

For example 8x + 7y = 15.

Given the equation,

√x - 3 + 1 = 6

√x + (-3 + 1) = 6

√x - 2 = 6

√x = 6 + 2 = 8

By squaring

x = 8² = 64.

Hence "The solution of the given equation √x - 3 + 1 = 6 will be x = 64".

Step-by-step explanation:

Travel time data is collected on an arterial. With 30 runs, an average travel time of 152 seconds is computed over the 2.0 miles length, with a computed standard deviation of 17.3 seconds.

Required:
a. Compute 95% confidence bounds on your estimate of the mean.
b. Was it necessary to make any assumption about the shape of the travel-time distribution?

Answers

Answer:

a

 The 95% confidence bounds is  [tex] 145.80 <  \mu <   158.19 [/tex]

b

It was not necessary to make any assumption about the shape of the travel  time distribution

Step-by-step explanation:

From the question we are told that

 The sample size is  n =  30  

  The sample mean  is  [tex]\=x = 152[/tex]

   The standard deviation is  [tex]\sigma = 17.3 \ second[/tex]

From the question we are told the confidence level is  95% , hence the level of significance is    

      [tex]\alpha = (100 - 95 ) \%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Generally the margin of error is mathematically represented as  

      [tex]E = Z_{\frac{\alpha }{2} } *  \frac{\sigma }{\sqrt{n} }[/tex]

=>    [tex]E =  1.96 *  \frac{17.3 }{\sqrt{30} }[/tex]

=>     [tex]E = 6.19  [/tex]  

Generally 95% confidence bounds  is mathematically represented as  

      [tex]\= x -E <  \mu <  \=x  +E[/tex]

=>  [tex]152  -6.19 <  \mu <  152  -6.19[/tex]

=> [tex] 145.80 <  \mu <   158.19 [/tex]

This 95% confidence bounds show that there is 95% confidence that the true mean lies within this bound hence there is it was not necessary to make any assumption about the shape of the travel  time distribution

Step-by-step explanation:

1.multiiply the numerator by 5

The numerator is the top number which is 3 in this case

So 3x5 is 15

You keep the denominator 4

so 15/4 that is an improper fraction now divide 15 by 4

or count by fours

4,8,12,16

16 is more than 15 so the new numerator is 12 and how many times did we count to fours? 3 times

so 3 is a whole now subtract the 12 you already took with 15. 3 is the extra so 3 wholes and 3 extras which is 3 3/4

Answers

Answer:

The measure of C is 10°

Step-by-step explanation:

In a triangle CDE, its internal angles are given:

C=x-4

D=11x-11

E=x+13

Since the sum of the internal angles of a triangle is 180°:

x-4+11x-11+x+13=180

Simplifying:

13x-2=180

Adding 2:

13x=182

Solving:

x=182/13

x=14°

The measure of the angles is:

C=x-4 =10°

D=11x-11=143°

E=x+13=27°

The measure of C is 10°

Quadrilateral EFGH is a scaled copy of quadrilateral ABCD. Select the true statement.

Answers

Answer:

segment EF is twice as long as segment AB

Step-by-step explanation:

Quadrilateral EFGH and quadrilateral ABCD are similar polygons. We can say that two polygons are similar if their corresponding angles are equal to each other and their corresponding sides are proportional to each other.

From the image attached, we can see that side CD and side GH are corresponding sides. The ratio of their sides are to be proportional.

GH / CD =  12 / 6 = 2

Therefore Quadrilateral EFGH is twice the size of Quadrilateral ABCD. Since side EF and side AB are proportional, therefore segment EF is twice as long as segment AB

Caught by a Treefrom Chatterbox 1906 A natural history student was one afternoon, during a prolonged drought, hunting for ferns in a dense wood. Towards evening, it grew suddenly dark, and a few drops of rain gave warning that a storm was coming. At that moment, the student's eye fell upon a big, hollow tree-trunk on the ground. Striking a match, the man peered within, and saw, as he thought, a convenient place of shelter. With feet foremost and arms pressed closely to his side, he wormed himself into the log. Presently the rain came down in torrents, and the student congratulated himself on having found so snug a shelter. Fatigued with his long tramp, he fell asleep. How long he slept he did not know, but by-and-by he was awakened by a sharp pain in his head, and a feeling of cramp in his whole body. The rain was still falling, the darkness was intense. The bodily discomfort was, of course, due to the man's cramped position; the pain in his head was caused by a continual drip of water from above on to his forehead. He drew his head back out of the way of the drops, and, in spite of his uncomfortable position, actually fell asleep again! But the next time he awoke, the pain in his head was intolerable. It seemed impossible to get out of reach of those maddening drops, and "wherever they fell," says the student, "they seemed like a sharp iron boring into the skull." But the worst was yet to come. When the poor fellow tried to crawl out of the log, he was unable to do so! The opening by which he had so foolishly entered had been only just large enough to admit his body, and the wood, shrunken by the long drought, had in the rain swelled to such an extent that he was now caught, as he says, "like a rat in a trap." Throughout the night the wretched victim shrieked, struggled, pushed, kicked, and wriggled in vain. He could not raise his hands to tear at the wood. Happily, he was discovered the next morning through the good services of a rescue dog, which led a search-party to the spot. 10Select all the correct answers.In what two ways does the setting influence the plot of the story? The setting adds an element of danger and suspense. The setting adds to the urgency of the search-party that is looking for the lost student. The setting creates the events that allow the dog to find the student trapped in the tree trunk. The setting creates the circumstances that lead to the student taking shelter in the tree trunk. The setting reveals the many hardships in the life of the student. Sometimes its hard to do this when you are involved in the situation.
