Answer :
12/3 which is = to 4

Answer:

Mean= 15.8, Median= 14.

Step-by-step explanation:

To find the mean, we need to find the average. We will simply need to add up all of the values and divide by how many there are.

Therefore:

[tex]\frac{14 + 19 + 20 + 12 + 14}{5}[/tex]= 15.8 = Mean.

To find the median, you can arrange the numbers in increasing order and find the middle value. You can do this like so:

12, 14, 14, 19, 20

The number in the middle of 14.

Answer:

On the first hour she gathered 8 mushroons, on the second 15 mushroons and on the third she gathered 14 mushroons.

Step-by-step explanation:

Helen gathred a total of 37 mushroons in three hours. On the first hour she gathered "x" mushroons, on the second hour she gathered "x + 7" mushroons and on the third hour she gathered "x + 6". Therefore the sum of mushrrons she gathered on each hour should be equal to the total she gathered as shown below:

37 = x + (x+ 7) + (x + 6)

37 = 3*x + 13

3*x + 13 = 37

3*x = 37 - 13

3*x = 24

x = 24 / 3

x = 8

On the first hour she gathered 8 mushroons, on the second 15 mushroons and on the third she gathered 14 mushroons.

Answer:

Helen gathered

8 mushrooms in the first hour,

15 mushrooms in the second hour and

14  mushrooms in the third hour.

The probability that the marble chosen at random from the bag is red is  1/3.

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability that the marble is red = total number of red marbles / total number of marbles

4 / 12 = 1/3

Answer:

£116.67

Step-by-step explanation:

Given;

Nar donated to 4 charities last year. She gave £175 to each of these charities.

The total amount Nar donated is;

Nar = 4 × £175 = £700

For Rana to donate the same amount equally among 6 charity, to determine the amount each charity would receive this year, we need to divide the total amount by the number of charities;

A = £700/6

A = £116.67

Answer:

t = 7.54 seconds

Step-by-step explanation:

The distance h(t) in feet traveled by a freely falling object is given by the function :

[tex]h(t)=16t^2[/tex]

The height of a tower is 912 feet.

It is required to find the time it will taken to fall on ground from the top of the building. It can be calculated as :

[tex]16t^2=912\\\\t=\sqrt{\dfrac{912}{16}}\\\\t=7.54\ s[/tex]

So it will taken 7.54 seconds to fall on the ground.

Answer:

x = 6

Step-by-step explanation:

The area of a triangle is given by

A = 1/2 bh where b is the base and h is the height

24 = 1/2 (8)x

24 = 4x

Divide each side by 4

24/4 = 4x/4

6 =x

Answer: b. The sample should be chosen at random so that it is fair.

Step-by-step explanation:

One of the most important things when selecting a sample is that the sample must be totally random if the sample is not random (for example, selecting only the youngest people in a group or things like that) there is a high probability that the sample will be biassed towards something, so the study may not be really accurate for all the population.

The correct option is b. The sample should be chosen at random so that it is fair.

Answer:

4 months

Step-by-step explanation:

Let the number of months that they deposit into their accounts be m.

Grace has $81 in her bank account and deposits $68 per month into her account. This means that after m months, she will have:

81 + 68m

Jasmine has $53 and deposits $75 per month into her account. This means that after m months, she will have:

53 + 75m

To find the number of months it will take for them to have the same amount, we equate the amount that they each have:

81 + 68m = 53 + 75m

Collect like terms and simplify:

81 - 53 = 75m - 68m

28 = 7m

=> m = 28 / 7 = 4

It will take 4 months for them to have the same amount.

Answer:

12 hours

Step-by-step explanation:

First to solve this problem, let's look at what we are dealing with here. It says that Ali made $126 for 9 hours of work.

Let's set that up into a fraction so it's easier to look at.

money/time = 126/9

Now that we have that set up let's look at our other piece of information.

It asks for how many hours would Ali have to work in order to make $168 so let's figure that out.

In order to find out the number of hours, let's first find our unit rate which can be simply found by dividing our given money/time.

126/9 = 14.

This means that for every 1 hour, there will be 14 dollars earned.

Now that we know that, let's look for how many hours it take to earn $168.

In order to do that simply see how many times 14 goes into 168 (division) and that way you can see how many hours it will take to earn $168.

168/14 = 12 hours.

Answer:

The length of a training track running around the field is  [tex]Z = 377.54 \ m[/tex]

Step-by-step explanation:

From the question we are told that

      The length of the field is  [tex]L= 93 \ m[/tex]

       The width of the field is  [tex]W = 61 \ m[/tex]

The length of the two semicircle is mathematically evaluated as

          [tex]A = 2 * \pi * \frac{W}{2}[/tex]

substituting values

          [tex]A = 2 *3.142 * \frac{61}{2}[/tex]

         [tex]A = 191.54 \ m[/tex]

Now the length of a training track running around the field is

       [tex]Z = A + 2 L[/tex]

  substituting values

       [tex]Z = 191.54 + 2 (93)[/tex]

       [tex]Z = 377.54 \ m[/tex]

Answer:

Option A)   Inside the circle

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The radius is equal to the distance from the center to any point on the circle

the formula to calculate the distance between two points is equal to

[tex]d\sqrt{(y2-y1)^2+(x2-x1)^2 }[/tex]

we have

A(-5,-8),M(-1,-3)

substitute the values

[tex]r=\sqrt{(-3+8)^{2}+(-1+5)^{2}}[/tex]

[tex]r=\sqrt{(5)^{2}+(4)^{2}}[/tex]

[tex]r=\sqrt{41}\ units[/tex]

step 2

Find the distance from the center to point V

we know that

If the distance from the center to point V is equal to the radius, then the point V lie on the circle

If the distance from the center to point V is less than the radius, then the point V lie inside the circle

If the distance from the center to point V is greater than the radius, then the point V lie outside the circle

we have

A(-5,-8),V(-11,-6)

substitute in the formula

[tex]d=\sqrt{(-6+8)^{2}+(-11+5)^{2}}[/tex]

[tex]d=\sqrt{(2)^{2}+(-6)^{2}}[/tex]

[tex]d=\sqrt{40}\ units[/tex]

so

[tex]\sqrt{40}\ units< \sqrt{41}\ units[/tex]

The distance from the center to point V is less than the radius

therefore

The point V lie inside the circle

Answer:

The focus should be on paying off Card 1 first

Step-by-step explanation:

The credit limit for card 1 is $10,000,invariably the cardholder only $ 1,687.31  

($10,000-$8,312.69) to reach its limit,hence available balance to draw from and also the annual percentage rate is higher for card card 1.

For every balance in card 1, the cardholder pays 24.16% APR annually compared to 21.15% applicable to card,as a result,card is cheaper.

Besides,the cardholder still has an available credit of $ 6,319.66  

($7,500-$1,180.34) on card 2 which comes at a lower APR

Answer:

$44.20

Step-by-step explanation:

First, calculate how many hours he worked. From 9:00am-3:30pm he worked 6.5 hours. We're going to multiply the hourly rate, $6.80 by how many hours he worked. Since he also worked an extra half hour and not a full hour we're going to divide $6.80 by 2. Then add both of the calculations up to get the asnwer.

6.8(6)=40.8

6.80/2=3.4

40.8+3.4=44.2

He earned $44.20.
