A nursery has 15 bags of topsoil. Each planter holds 1/8 of a bag.
Svetlanka [38]

Answer:

120 planters can be filled with topsoil.

Step-by-step explanation:

Since each planter can hold 1/8th of a bag of topsoil, this means that one bag of topsoil can fill up 8 planters.

15 x 8 = 120, so this means that 120 planters can be filled with topsoil.

A plant can manufacture 100 golf clubs per day for a total daily cost of $7,800 and 120 golf clubs per day for a total daily cos
Bezzdna [24]

Answer:

The correct option is (B) 250.

Step-by-step explanation:

A plant can manufacture 100 golf clubs per day for a total daily cost of $7,800.

And 120 golf clubs per day for a total daily cost of $8,400.

Let <em>X</em> = number of golf clubs manufactured per day.

Let <em>Y</em> = total cost of manufacturing golf clubs per day

It is provided that:

(<em>x</em>₁, <em>y</em>₁) = (100, 7800)

(<em>x</em>₂, <em>y</em>₂) = (120, 8400)

Form the least square regression line using two-point form as follows:

(y-y_{1})=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\ (x-x_{1})

(y-7800)=\frac{8400-7800}{120-100}\ (x-100)\\\\(y-7800)=30\times (x-100)\\\\y-7800=30x-3000\\\\y=30x+4800

The least square regression line to estimate the total daily cost of <em>x</em> golf clubs  manufactured daily is:

<em>y</em> = 30 <em>x</em> + 4800

Compute the  number of golf clubs manufactured if the total daily cost is $12,300 as follows:

y = 30 x + 4800\\12300=30x+4800\\30x=7500\\x=250

Thus, the correct option is (B).
