A typing instructor builds a regression model to investigate what factors determine typing speed for students with two months of

instruction. Her regression equation looks like: Y' = 11 + 7x1 + 5x2 + 3x3 where: Y' = typing speed in words per minute; x1= hours of instruction per week; x2= hours of practice per week; x3 = hours of typing per week necessary for school or work; A new student is taking 2 hrs of typing instruction per week, will practice 5 hrs per week and must type 2.5 hours per week for work. If the standard error of the estimate is 2, within what range do we have a 95.45% probability that that student's typing speed will be in two months?
Select one:
a. 53.5 and 61.5 words per minute
b. 49.5 and 65.5 words per minute
c. 57.5 and 65.5 words per minute

Roman buys seed packets for the school garden. One packet of radish seeds costs $1. 75. One packet of tomato seeds costs $2. 50.
bezimeni [28]

Roman may buy 23 tomato and 9 radish,  for the school garden.

 

<h3><u>Calculation:</u></h3>

Let (r) represent the cost of one packet of radish seeds, and

Let (t) represent the cost of one packet of tomato seeds.

Amount spent by roman = $62.75

It denotes that;

\ 1.75r +2.5t = 62.75.......equn. 1

Roman bought 32 packets of seeds and one packet of radish seeds costs = $ 1.75.

One packet of tomato seeds costs =  $ 2.50.

It denotes that,

\ r+t=32.....equn.2

Substitute t=9 , and r= 23, we have

In eq. 1

\ = 1.75\times9 + 2.5\times23 = 62.75\\ = 15.75+57.5 \neq  62.75 \\ = 62.75 = 62.75

In eq.2

\ =32=23+9 = 32\\

Here, both the equations are satisfied, therefore, option [C] is correct.
