Step-by-step explanation:

There are approximately 3,000 bass in a lake. The population grows at a rate of 2% per year. Round answers to the nearest tenth.

From Year 1 to Year 4, the average rate of change of the population was about 62.4 bass per year.

From Year 5 to Year 8, the average rate of change of the population was about 67.6 bass per year.

The rate of change increased by about _____ bass per a year.

Answers

Answer:

years 1–4: 62.4 bass per year

years 5–8: 67.6 bass per year

Step-by-step explanation:

If the population in year n is ...

 p(n) = 3000·1.02^n

then the average rate of change from year 1 to year 4 is ...

 (p(4) -p(1))/(4 -1) = 3000(1.02^4 -1.02^1)/3 = 1020·(1.02^3 -1) ≈ 62.4

The average rate of change for years 1–4 is 62.4 bass per year.

___

For years 5–8, the rate of change is similarly computed:

 (p(8) -p(5))/(8 -5) = 3000(1.02^8 -1.02^5)/3 = 1000·1.02^5·(1.02^3 -1) ≈ 67.6

The average rate of change for years 5–8 is 67.6 bass per year.

A line is reflected, what line is the results?

Answers

Answer:

A I think

Step-by-step explanation:

I dont really get the question so im not sure

Answer:

C.

Step-by-step explanation:

The question states that a LINE is reflected, just with this information we know that A. is incorrect because it is curved.

At first, when looking at B., it seems as though it could work, until you notice that it starts somewhere, but doesn't end, thus it is not a LINE. So, we can count B as incorrect as well.

When looking at C, it it a straight line, and has a beginning and and end, which means that so far, it is the most likely the line.

Then, we look at D. When looking at D, we can tell that it is a straight line, however, it has no beginning and no end, thus it can't be the answer.

Now, we know that C is the only possible answer for this question.

One pumpkin weighs 7 lb 12 oz. A second pumpkin with 10 pounds 4 ounces. A pumpkin weighs 2 pounds 9 ounces more than the second pumpkin what is the total weight of all three pumpkins?

Answers

Answer:  30 lbs, 13 oz

This converts to 493 ounces

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

Explanation:

Pumpkin A weighs 7 lb, 12 oz. Let's convert that to ounces only

1 lb = 16 oz

7 lbs = 112 oz (multiply both sides by 7)

7 lbs, 12 oz = 112 oz + 12 oz .... add 12 oz to both sides

7 lbs, 12 oz = 124 oz

Pumpkin A's weight of 7 lbs, 12 oz is the same as 124 oz

-----------

Do something similar for pumpkin B

1 lb = 16 oz

10 lbs = 160 oz

10 lbs, 4 oz = 160 oz + 4 oz

10 lbs, 4 oz = 164 oz

Pumpkin B weighs 164 oz

-----------

Let's convert the "2 lbs, 9 oz" to ounces only

1 lb = 16 oz

2 lbs = 32 oz

2 lbs, 9 oz = 32 oz + 9 oz

2 lbs, 9 oz = 41 oz

So pumpkin C is 41 ounces heavier compared to pumpkin B

The weight of pumpkin C is 164+41 = 205 ounces

----------

We have these three weights in ounces only

Pumpkin A = 124 ozPumpkin B = 164 ozPumpkin C = 205 oz

Adding those three ounces only weights leads to

124+164+205 = 493 ounces

The total weight of all three pumpkins is 493 ounces

Now let's convert back to the unit "pounds, ounces"

Divide that result over 16 since there are 16 ounces per pound

493/16 = 30.8125

Ignore the decimal portion. The 30 is the quotient which means 493-30*16 = 13 is the remainder.

In other words,

493/16 = 30 remainder 13

which leads to

493 ounces = 30 pounds, 13 ounces

--------------

As a check,

1 lb = 16 oz

30 lbs = 480 oz

30 lbs, 13 oz = 480 oz + 13 oz

30 lbs, 13 oz = 493 oz

The answer is confirmed.

Answers

Answer:

8 cm cubed

Step-by-step explanation:

Because that the cubes are well, cubes, all the sides are the same. If 1 side= 1, then the other ones are too. Once you look at the prism, you will notice that there are 8 cubes in total. Let's find the volume of 1 cube first:

The formula is:

w*h*l = v

1*1*1=1

The volume for 1 cube is 1 cm cubed.

1*8=8

The volume for the prism is 8 cm cubed.

Answer: 24cm^3

Explanation: The side of each cube measures a centimeter, and there are 4 on each side of the prism. Since the prism has 6 sides, we can multiply 6 by 4 to get an answer of 24cm^3.

A group of students were surveyed to find out if they like playing tennis or volleyball in PE class. The results are shown in the table:
Complete the table and answer the following questions.
a. What percentage of the total students surveyed like both
Volleyball and Tennis?

b. What is the probability that a student who does like
Volleyball does not like Tennis?

Answers

Using the probability concept, it is found that:

a) 41.67% of the total students surveyed like both Volleyball and Tennis.

b) There is a 0.1667 = 16.67% probability that a student who does like

Volleyball does not like Tennis.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Item a:

There is a total of 70 + 50 = 120 students, and x + 20 = 70 -> x = 50 like both sports, hence:

p = 50/120 = 0.4167.

41.67% of the total students surveyed like both Volleyball and Tennis.

Item b:

60 students like voleyball, and of those, 10 do not like tennis, hence:

p = 10/60 = 0.1667 = 16.67%.

There is a 0.1667 = 16.67% probability that a student who does like

Volleyball does not like Tennis.
