Answer:

4) 1400 $in^3$

5) 304 $\Pi$ or 954.56 $yd^3$

6) 315 $ft^2$

Step-by-step explanation:

$4)$

$V = \frac{lwh}{3} = \frac{20*20*10.5}{3} = \frac{4200}{3} = 1400$

$5)$

$A = \Pi(\frac{D}{2})^2 = \Pi(\frac{8}{2})^2 = \Pi*4^2 = 16\Pi$

$V = A * h = 16\Pi * 19 = 304\Pi = 304 * 3.14 = 954.56$

$6)$

$h^2 = 8^2 + 8^2 => h^2 = 64 + 64 = 128 => h =\sqrt{128}$

$A_1 = 2(\frac{8*\sqrt{128}}{2}) = 8*\sqrt{128} = 32 = 90.5$

$A_2 = 2(14 * 8) = 2*112 = 224$

$A = A_1 + A_2 = 91 + 224 = 315$

The mathematics faculty at a college consists of 9 professors, 8 associate professors, 10 assistant professors, and 10 instructo

Reika [66]

Answer:

19/37

Step-by-step explanation:

The mathematics faculty at a college consists of 9 professors, 8 associate professors, 10 assistant professors, and 10 instructors. If one faculty member is randomly selected, find the probability of choosing a professor or an instructor

Total number of people in the faculty =

9 professors + 8 associate professors+ 10 assistant professors+ 10 instructors

= 37 people

Hence,

The probability of choosing a professor or an instructor

= P( Professor) + P( Instructor)

= 9/37 + 10/37

= 19/37
