Confused on the question could I have a picture?
If M <span>is the midpoint of AB then AB = 2AM
8x - 6 = 2(3x + 3)
8x - 6 = 6x + 6
8x - 6x = 6 + 6
2x = 12
x = 12/2
x = 6
AM = 3x + 3 = 3*6 + 3 = 18 + 3 = 21 units

Answer:
(a) 20 ways
(b) 0.05 or 5%
Step-by-step explanation:
(a) Assuming that the order in which people are chosen does not matter, the number of ways to select 3 people out of possible 6 is given by the following combination.

(b) In a random sampling procedure, every outcome is just as likely to occur. Therefore, the chances that any particular sample will be the one selected are:

Answer:
286 miles / x gallons = 15miles per gallon.
286/15 = x = approximately 19.07 gallons.
Step-by-step explanation:
Answer:
50
Step-by-step explanation:
and
can be expressed in complex form, with
= i
=
=
×
= 8i
=
=
×
= 4i
the factors can then be expressed as
(6 + 8i)(3 - 4i) ← expand using FOIL
= 18 - 24i + 24i - 32i² [ i² = (
)² = - 1 ]
= 18 - 24i + 24i + 32 ← collect like terms
= 18 + 32 + 0
= 50
