5 0

Answer:

a. the line that passes through the most data points.

Step-by-step explanation:

Regression analysis, is used to draw the line of‘ best fit’ through co-ordinates on a graph. The techniques used enable a mathematical equation of the straight line form y=mx+c to be deduced for a given set of co-ordinate values, the line being such that the sum of the deviations of the co-ordinate values from the line is a minimum, i.e.

The least-squares regression lines  is the line of best fit

Which equation can be used to solve for m, the greater integer? m(m – 3) = 108 m(m + 3) = 108 (m + 3)(m – 3) = 108 (m – 12)(m –
nata0808 [166]

Answer:

m(m-3)=108

Step-by-step explanation:

Complete question below:

Two positive integers are 3 units apart on a number line. Their product is 108.

Which equation can be used to solve for m, the greater integer?

m(m – 3) = 108

m(m + 3) = 108

(m + 3)(m – 3) = 108

(m – 12)(m – 9) = 108

Solution

On the number line,

Let

m= larger integer

The integers are 3 numbers apart on the number line, so

m-3=smaller integer

The product (×) of the larger and smaller integers=108

(m)*(m-3)=108

m(m-3)=108

Therefore, the equation that can be used to solve for m, the larger integer is:

 m(m – 3) = 108

Oreos 2.98 for 15.5.Oz or chips ahoy for 2.50 for 14.Oz I pick chips ahoy BUT ITS ASKING UNIT RATE CENTS PER OZ
LiRa [457]

Answer:

Unit rate of oreos = 19.23 cents/oz

Unit rate of Chips Ahoy = 17.86 cents/oz

The cheapest and most affordable is the chips ahoy because it has a lower unit rate.

Step-by-step explanation:

Oreos 2.98 for 15.5.Oz or chips ahoy for 2.50 for 14.Oz I pick chips ahoy BUT ITS ASKING UNIT RATE CENTS PER OZ

We would be finding the Unit Rate of each product.

For Oreos

Oreos $2.98 for 15.5.Oz

We convert dollars to cents

1 dollars = 100 cents

2.98 dollars = x

x = 2.98 × 100 cents

= 298 cents

Hence, the unit rate in cents/oz

= 298 cents/15.5 oz

= 19.225806452 cents/oz

= 19.23 cents/oz

For Chips ahoy

$2.50 for 14.Oz

We convert dollars to cents

1 dollars = 100 cents

2.50 dollars = x

x = 2.50 × 100 cents

= 250 cents

Hence, the unit rate in cents/oz

= 250 cents/14 oz

= 17.857142857 cents/oz

= 17.86 cents/oz

Therefore, the cheapest and most affordable is the chips ahoy because it has a lower units rate.
