In circle R with QRS=90 and QR= 3 units find the length of arc QS round to the nearest hundredth
luda_lava [24]

Hello, I Am BrotherEye

Answer:

27.92 units

Step-by-step explanation:

Radius (qr) = r = 16 units

<QŘS = θ = 82°

Length of an arc = (Θ / 360) * 2πr

L = (θ / 360) *2πr

L = (82 / 360) * 2π * 16

L = 0.2777 * 100.53

L = 27.917 units

L = 27.92 unit

Best Of Luck

A regression analysis between sales (y in $1000) and advertising (x.in dollars) resulted in the following equation: ỹ= 30,000 +
Dafna11 [192]

Answer:

Correct answer is option d. increase of $1 in advertising is associated with an increase of $4000 in sales.

Step-by-step explanation:

Given the equation of regression analysis is given as:

y= 30,000 + 4x

where x is the cost on advertising in Dollars.

and y is the sales in Thousand Dollars.

To find:

The correct increase in sales when there is increase in the advertising cost.

Solution:

Suppose there is an increase of \$1 in the advertising cost.

Let the initial cost be x then the cost will be (x+1).

Initial sales

y= 30,000 + 4x ....... (1)

After increase of $1 in advertising cost, final cost:

y'= 30,000 + 4(x+1)\\\Rightarrow y' = 30,000+4x+4\\\Rightarrow y' = 30,004+4x ..... (2)

Subtracting (2) from (1) to find the increase in the sales:

y'-y=30004+4x-30000-4x = 4

The units of sales is Thousand Dollars ($1000).

So, increase in sales = 4 \times1000 = \bold{\$4000}

So, correct answer is:

d. increase of $1 in advertising is associated with an increase of $4000 in sales.
