At a large university, 15% of students are business majors and 20% are communications majors. If two students are selected at ra

denis-greek [22]

Answer:

Probability the first is a communications major and the second is a business major = 0.03

Step-by-step explanation:

let the total number of students be 100

Event A= Business Majors = 15%

Event B = Communication Majors = 20%

P(A) = $\frac{15}{100}$ ⇒ P(A) = 0.15

P(B) = $\frac{20}{100}$ ⇒ P(B) = 0.2

P( A and B) = P(A) × P(B)

= 0.15 × 0.2

= 0.03

A rectangular field has an area of 1,764 m2. The width of the field is 13 m more than the length. What is the perimeter of the f

Gnoma [55]

Hello,
Here in France we call length the greater side of a rectangle.
So:
Let a the greater side
b the shortest

a=b+13
a*b=1764
==>b*(b+13)=1764
==>b²+13b-1764=0
==>b=(-13-85)/2 to exclude
or (b=(-13+85)/2=36 and a=36+13=49)

P=2(a+b)=2(36+49)=170 (m)
Proof:
49-36=13
36*49=1764

If cosθ=40/41,find sinθ,cotθ,secθ

fgiga [73]

Hello.

Angle Theta is equal to: x² + y² = r² OR $r = \sqrt{ x^{2} + y^{2} }$

40² + y² = 41²
1600 + y² = 1681
-1600 -1600
y² = 81
y = 9

x = 40, y = 9, r = 41

<span>cos θ= </span> $\frac{x}{r}$ = $\frac{40}{41}$

sin θ = $\frac{y}{r} = \frac{9}{41}$
cot θ = $\frac{x}{y} = \frac{40}{9}$
sec θ = $\frac{r}{x} = \frac{41}{40}$

Hopefully it makes sense! :)
