Answer:
7 / 30
Step-by-step explanation:
This is a selection without replacement probability :
Total boxes = 16
With money = 3
With traveling prices = 5
Empty = 8
P(choosing 2 empty boxes) :
P(empty) * P(empty)
P(empty) = Number of empty boxes / total number of boxes
First pick = empty
P(empty) = 8 / 16 = 1/2
Without replacement :
Second pick = empty
P(empty) = 7 / 15
P(choosing 2 empty boxes) = 1/2 * 7/15 = 7 /30
Answer:
c
Step-by-step explanation:
quadratic formula: -b±√b²-4ac/ 2a
a= -10
b= 12
c= -9
-12±√144- 4(-10)(-9)/ 2(-10)
-12±√144- 360/ -20
-12±√-216/-20
6±3i√6/ 10
simplify: 3/5± 3i√6/10
Answer:
The domain is (-2, 8, 3, 2)
Step-by-step explanation:
The domain is such because domain is the x-element or the one you see at first in the ordered pairs.
Answer:
x=105
Step-by-step explanation:
75+75+x+x=360
150+2x=360
2x=210
x=105
I hope this is correct and helps you!
Answer:
x = 25 degrees.
Step-by-step explanation:
By the external angle of a triangle theorem x + <C = 50
But x = <C ( alternate angles).
Therefore 2x = 50
x = 25.
