Choose the best estimate for the total amount spent for all 10 calculators.
O A. $805
OB. $490
OC. $550
OD. $660

Answers

Answer:

310

Step-by-step explanation:

least money 19.95

Most money = 39.95

Mean = (least+most)/2 = 29.95

money for half people = 5 × (mean) 29.95

Amount of money for half people = 149.75

Lower limit for amount of the other half = 19.95 × 5 = 99.75

The Upper limit for the amount of the other half = 39.95 × 5 = 199.75

Mean = (99.75 + 199.75)/2 = 149.75

Total money spent (Mean) = 149.75 + 149.75 = 299.5

The Best estimate is B) 310 because it is closest to 295.5

A mean is an arithmetic average of a set of observations. The correct option is D.

What is Mean?

A mean is an arithmetic average of a set of observations. It is given by the formula,

Mean = (Sum of observations)/Number of observations

To make the calculations easy let's round off the given numbers. Therefore, we can write the values as,

Least expensive A=30Most expensive B=90half of order C=70

Now, the mean and the money for half the people can be written as,

Mean = (least + most)/2 = 60

money for half people = 5 × 60

Therefore, the amount of money for half people will be,

Amount of money for half people = 300

Lower limit for amount of the other half = 29.95 × 5 = 149.5

The Upper limit for the amount of the other half = 89.95 × 5 = 449.75

Mean = (149.75 + 449.75)/2 = 299.6

Total money spent (Mean) = 299.6 + 299.6 = 599.25

Hence, The Best estimate is $660. This is because it is closest to 599.25.

An explorer is climbing up and rappelling down a series of cliffs and drop-offs. She starts at her base camp, which is on the middle of a mountain. She begins by rappelling down an 82.5-foot drop-off and then climbs a cliff of 30.4 feet. Next she rappels down a 45.5-foot drop-off and then climbs a 25.2-foot cliff.Finally she makes two 45.4-foot climbs. Part A: How far above or below her base camp is the explorer now?

Answers

Answer:

162.8 above her camp site she starts at the middle and drops 82.5 and then climbs 30.4 which puts her at 52.1 then by her repelling down another 45.5 drop she then proceeds to climb 25.2 which puts her at 72.4 and if you multiplie 45.4 by 2 it counts for the extra 90.4 drop which then concludes her climb to be bellow her site by 162.8 and the 1st word is supposed to be bellow my bad.

The distance around a yard is 588ft. If the length of the yard is 2 more than 3 times the width, find the perimeter and width of the yard

Answers

Answer:

Perimeter = 588ft (given), Width of yard = 73ft

Step-by-step explanation:

The distance around a yard is the perimeter of the yard, so we know that the perimeter of the yard is 588ft. In order to find the length and width, we need to make an equation so we can solve for one of them. Since the length is 2 more than 3 times the width, we can represent it as 3w+2, where w is the width. This ensures we only have one unknown to solve for as we only have one equation. Since perimeter is the distance around the yard, it is calculated by adding the length of the 2 widths to the length of the 2 lengths, hence 588ft = 2w + 2l, the l we replace though as we can only solve for one unknown, so now we have:

2w + 2(3w+2) = 588

Now we can start solving for the width!

Firstly we need to expand the bracket which we do by multiplying the 2 by all the contents inside the bracket, so:

2w + 2*3w + 2*2 = 588

which equals:

2w +6w +4 = 588

Now we combine terms and move the 4 to the other side so we can solve for w:

8w + 4 -4 = 588 - 4

8w = 584

Now we just divide both sides by 8 to get:

w=73

The width of the yard is 73ft.

The toy horse collection contains 10 horses. You purchase the set and then sell 3 horses to Kate. If you only charge the exact price (no tax involved), how much does Kate pay you?

Answers

Answer:

three tenths of the original amount

Let's start.

There are 10 horses.

(Buying the set is not important, since it does not affect this scenario.)

You sell three horses to Kate, and you expect her to give you the exact price.

Let's say that 10 horses cost the total (unknown).

10 horses equal the total amount, or 1

10 to 1

Now, you sell 3 of these horses. You must multiply 10 and n to make 3.

10 x n = 3

10x 3/10 = 3

Do the same to the other side.

1 x 3/10 = 3/10

3 to 3/10

A media personality argues that global temperatures are not rising, because every year an increase is reported such as 0.08 degrees C. The difference from the previous year is less than the margin of error of about 0.15 degrees C, so that difference should be ignored. What is a strong counterargument?

Answers

Answer

:we are told that every year the temperature rises by 0.08degrees Centigrade,

So the difference between margin of error and the increase is much higher

That is

0.15-0.08=0.07

But remember Margin of error=Critical value *Standard deviation of population

And it is a quantity that measures accuracy

So the counter argument is that this is still an increase and it should be considered.

Luego de estudiar el proyecto, los promotores estiman que es más conveniente un tamaño de 19 200 toneladas por año. ¿A cuánto ascenderá la inversión total, si el exponente del factor de escala es α=0,63? ayuda !!!!!

Answers

Answer:

En caso de un tamaño de producción de 19,200 toneladas anuales, el costo de inversión total ascenderá a $3,999,936.

Step-by-step explanation:

Dado que la inversión inicial será de $ 2,500,000 para un tamaño de planta de 12,000 toneladas anuales, se estima que cada tonelada requiere una inversión de $208.33 (2,500,000 / 12,000).

Por lo tanto, en caso de una producción anual de 19,200 toneladas, el costo de inversión aumentará según lo establecido en la siguiente multiplicación:

208.33 x 19,200 = X

3,999,936 = X

Por lo tanto, en caso de un tamaño de producción de 19,200 toneladas anuales, el costo de inversión total ascenderá a $3,999,936.
