HELP PLEASE!!!
Hitman42 [59]

Answer:

1. false

2. 17 times

Step-by-step explanation:

The sum of all the probabilities of outcomes of an event is equal to 1

2.  A die has  1,2,3,4,5,6

P(4) = number of 4's/ total numbers

       = 1/6

Multiply the number of roll's by the probability of getting a 4

100 *1/6 = 50/3 = 16 2/3

This is approximately 17

River C is 200 miles longer than River D. If the sum of their lengths is 5580 ​miles, what is the length of each​ river?
Valentin [98]

Yo sup??

Let the length of river D be x

then the lenght of river C will be 200+x

but,

lenght of river C+lenght of river D=5580

x+x+200=5580

2x=5380

x=2690

Therefore lenght of river D is 2690 and that of C is 2890

Hope this helps

List all x intercepts for y= -cos(1/2x + 1/5 pi) on the interval [-2/5pi,4pi]
Dahasolnce [82]
- cos ( 1/2 x + 1/5 π ) = 0 ( and because if cos α = 0, α= π/2 + k π, k ∈ Z )
1/2 x + π/5 = π/2 + k π,    k ∈ Z
1/2 x = π/2 - π/5 + k π  / * 2
x = π - 2π/5 + 2 k π
x = 3/5 π + 2 k π = 0.6 π + 2 k π
Answer:
If k = 0:  x 1 = 0.6 π = 3π/5
k = 1 : x 2 = 2.6 π = 13π/5
