The operation is known as rounding of a number.

This means basically if i measure the temperature of a city and it comes out to be 22.9 degrees. I will round it of to 30 degrees or the amount of significant figures i am designated with.

Similarly if its 22.85 and i have to round of to 3 significant figures it becomes 22.9 degrees.

ROunding off is obviously done watching to which digit we have to.

This operation is called rounding. 

For example, if I scored 97.9 points on a math test, I could round it up to 98. Or, if I scored 92.1 points, then I could round it down to 92. In both cases, the real math scores (both of which are decimals) are replaced by different, whole numbers.

The estimate of the total sales is $3,055,510.08.

First I created a scatter plot of the data given for yellow golf balls and calculated the linear regression for it.  Screenshots are attached.

The regression equation (equation for the line of best fit) was 
y = 16488x + 189312, where x represents the year number and y is the total yellow golf balls.

We are concerned with year 4, so we will substitute 4 for x:
y = 16488(4) + 189312 = 255,264

There will be around 255,264 yellow golf balls sold in year 4.

Since the ratio of yellow to white golf balls is 1:5, we can set up a proportion:
1/5 = 255264/x

Cross multiply:
1*x = 5*255264
x = 1,276,320

We expect the company to sell 1,276,320 white golf balls.  This makes a total of:

1,276,320 + 255,264 = 1,531,584 total golf balls expected to be sold in year 4.

Since these are sold in boxes of 12, we divide this by 12:
1,531,584/12 = 127,632 boxes expected to be sold

Each box is 23.94:
127632*23.94 = 3,055,510.08

Carl can buy a 16 ounce package of trail mix for $9.87, or he can make his own trail mix for 65 cent an ounce. Will carl save mo
nasty-shy [4]

Answer:

Carl can save <u>3 cents</u> when he buys a 16 ounce package.

Step-by-step explanation:

Given:

16 ounce package of trial mix = $9.87

1 ounce of trial mix he can make = 65 cents.

We need to find whether Carl will save money if he buys the 16 ounce package.

Solution;

Now we will find the Cost for 1 ounce of trial mix when he buys 16 package of trial mix.

16 ounce package of trial mix = $9.87

1 ounce of trial mix = Cost of 1 ounce of trial mix when a package of 16 ounce of trial mix is bought.

Using Unitary method we get;

Cost of 1 ounce of trial mix when a package of 16 ounce of trial mix is bought. = \frac{9.87}{16}= \$0.62\ \ \ \ Or\ \ \ \  62\ cents

Now from above we can see that;

When a package of 16 ounce of trial mix is brought then 1 ounce of trial mix cost 62 cents while when he prepares his own trial mix the cost of 1 ounce of trial mix is 65 cents.

So we can say that;

Carl can save <u>3 cents</u> when he buys a 16 ounce package.

Svetlanka [38]

Answer:

perpendicular

Step-by-step explanation:

Convert into y = mx + b form

5y = 6x + 1

y = 6/5x + 1/5

6y = -5x - 4

y = -5/6x - 2/3

Since the y int are different, and the slopes are perpendicular (neg reciprocal), the 2 lines are perpendicular
