Step-by-step explanation:
7. I believe it's independent because it makes sense and if it was dependent it wouldn't make senses.
8.For T you have 2 (Ts) so that give you a 2/8= 25% so you would basically make those Ts disappear and focus on 1 out of 6 and you'd get a 16.67% chance
9. 14.2857%
10. I don't understand ;-; am I suppose to multiply or see the chance if % it would get
I'm sorry;-;
Answer:
im pretty sure it's $19.80
Step-by-step explanation:
(44 x 55)/100 = $24.20
44 - 24.20 = $19.80
Answer:
1200 miles.
Step-by-step explanation:
Let d represent one way distance.
We have been given that a plane averaged 800 mph on a trip going east, but only 400 mph on the return trip.
The time taken while going east would be 
.
The time taken while returning back would be 
.
Since the total flying time in both directions was 4.5 hr, so we will equate sum of both times with 4.5 as:
Make a common denominator:
Therefore, the one-way distance was 1200 miles.
Plug -6 in for x and solve.
y = (-1/3)(-6) + 5
y = 2 + 5
y = 7
Answer:
The answer is A) y = -4/3x + 5/3 and D) 4x + 3y = 5
