The mean is found by adding together all of the numbers, then dividing that number, by how many numbers you have. (In this case it would be 68.7 divided by 24 which is 2.8625). This means 2.8625 is the average/ mean.

The median is found by lining all the numbers you have up from least to greatest. Then you cross out one on each side and continue crossing until you reach the middle. In this case, the median would be 1.4.

The correct answer is c, only the mean will increase

The price of gold is often reported per ounce. At the end of 2005, this price was $513. At the end of 2015, it was $1060. By wha

erastova [34]

Answer:

106.63%.

Step-by-step explanation:

We have been given that at the end of 2005, this price was $513. At the end of 2015, it was $1060.

To find the percentage of the price per ounce of gold increase we will use % increase formula.

$\text{Percent Increase}=\frac{\text{Final value-Initial value}}{\text{Initial value}}\times 100$

Let us substitute our given values in above formula.

$\text{Percent Increase}=\frac{1060-513}{513}\times 100$

$\text{Percent Increase}=\frac{547}{513}\times 100$

$\text{Percent Increase}=1.0662768031189084\times 100$

$\text{Percent Increase}=106.62768031189084\approx 106.63$

Therefore, the price of per ounce of gold increased by 106.63%.

What is the best approximation of the surface area of this right cone

Tatiana [17]

Use the formula for the surface area of a right cone:

$\sf A=\pi rs+\pi r^2$

Where 'r' is the radius and 's' is the slant height, plug in what we know(use 3.14 to approximate for pi):

$\sf A=(3.14)(12)(15)+(3.14)(12)^2$

Multiply and simplify exponent:

$\sf A=565.2+(3.14)(144)$

Multiply:

$\sf A=565.2+452.16$

Add, round to the nearest whole number:

$\boxed{\sf A\approx 1017~cm^2}$
