The probability of selecting 2 same colors when the first is not replaced
The total number of ball is:
This is calculated as:
So, we have:
<em>Note that: 1 is subtracted because it is a probability without replacement</em>
Answer:
6 6/7 km/h
Step-by-step explanation:
The relations between speed, time, and distance are ...
time = distance/speed
speed = distance/time
__
So, to find the average speed, we need to know the total distance and the total time. The distances are given, but we need to compute the times.
time jogging = (2 km)/(8 km/h) = 1/4 h
time walking = (2 km)/(6 km/h) = 1/3 h
Then the woman's average speed is ...
average speed = (total distance)/(total time) = (2 km + 2 km)/(1/4 h + 1/3 h)
= (4 km)/(7/12 h) = 48/7 km/h
= 6 6/7 km/h
Would it be 5 ? i’m sorry i’m not very sure.
Step-by-step explanation:
-2, -8/3, -10/3, -4, -14/3
Write as multiples of 1/3.
-6/3, -8/3, -10/3, -12/3, -14/3
This is an arithmetic sequence where the first term is -6/3 and the common difference is -2/3.
Therefore, the recursive formula is:
aᵢ₊₁ = aᵢ − 2/3, a₁ = -2
Answer:
The total cost y of a meal.....
Step-by-step explanation:
The total cost of the meal Y suggests addition, which if you added the x and w portions, you would end up with y.
The other answers suggest subtraction, division, or multiplication, which is not being illustrated by the model.
