help me with number 5 please

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:

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

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.

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.

Step-by-step explanation:

To find the area of the head of the nail you need to use the*

> A= π*r^2* A equals area, π equals pi(3.14) and then you square your raidius, which is 6 in your case.

π*r^2

plug in your six as the *r

π*6*^2

solve 6^2=36 and multiply that by your π which is 3.14

3.14*36

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:

-7

Step-by-step explanation:

(x²+6x-16)(x-2) = x³+4x²-28x+32

x³+4x²-28x+32 = ax³+bx²+cx+d

a=1; b=4; c= -28; d= 32

-28/4 = -7

I believe 80 percent of 25 is 20.

Step-by-step explanation:

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".

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.
