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.

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

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.

Answer:

Step-by-step explanation:

y = 4x + 5

It is in y = mx + c form

Slope (m) = 4

2y = 8x + 15             {Divide both sides by 2}

[tex]\frac{2y}{2}=\frac{8}{2}x+\frac{15}{2}\\\\y = 4x +\frac{15}{2}[/tex]

Slope = 4

If two lines have same slope, then they are parallel lines.

As you know, parallel lines have never intersect, this system of linear equations have no solution.

Answer:

y = 3(-4)+5 = -7

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.

Step-by-step explanation:

First, I had to find the total number of dinners, next I had to find how many had prices of "$30 or more." Last, I had to find the total number of dinners who had prices of less than $30.

Total: 10

Less than 30: 3

10 - 3 = 7

7 = Prices of Dinners ($30 or more)

Hope this helps a bit!

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.

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.

Answer:

195.6 inches squared

Step-by-step explanation:

First we find the value of one of the big triangles.

(14*8*0.5)

56

Next, we find the value of the three of them combined.

56+56+56 or 56*3

168

Now, we find the value of the smaller triangle.

(6.9*8*0.5)

27.6

Because we only have one small triangle, we don't need to do what we did with the other one now.

The last step is to add the area of the three triangles with the smaller triangle.

168+27.6

195.6

The surface area of the (shape...?) is going to be 195.6 in. squared.

Answer:

a = -5

Step-by-step explanation:

a = 1/2(-10) + 3^2 - (-1) - 10

a = -5 + 3^2 - (-1) -10

a = -5 + 9 - (-1) - 10

a = 4 - (-1) - 10

a = 4 + 1 - 10

a = 5 - 10

a = -5

x = -1y = 3

z = -10

a = -5

The opinion of Aiden about equivalent expressions always having the same number of terms is; Not correct

Aiden is not correct with his assertion as we will see for four major operations.

We can see that in both cases the expressions have equivalent answers but the number of terms are not the same.

Same scenario also applies for division and subtraction. Thus, we can say that Aiden is not correct.
