There are 16 possible outcomes.
This is found by taking the number of possible outcomes for each toss, 2, and raising it to the 4th power (for 4 tosses):
2⁴ = 2*2*2*2 = 16
Answer:
u = 2/3
Step-by-step explanation:
Simply divide both sides by -8:
u = (-16/3)/-8
If you don't have a calc, use KCF:
u = (-16/3)(-1/8)
u = 16/24
u = 2/3
Top answer is -4 because when you divide by a negative your answer will come out negative and bottom answer is 6 because when you multiply two negatives it turns into a positive
<h2>T
he car is about 6.6 years old.</h2>
Step-by-step explanation:
Given : An equation for the depreciation of a car is given by
, where y = current value of the car, A = original cost, r = rate of depreciation, and t = time, in years. The value of a car is half what it originally cost. The rate of depreciation is 10%.
To find : Approximately how old is the car?
Solution :
The value of a car is half what it originally cost i.e. 
The rate of depreciation is 10% i.e. r=10%=0.1
Substitute in the equation, 


Taking log both side,




Therefore, the car is about 6.6 years old.
Answer:
In one hour Stephanie earns $1.50 more than Marco
Step-by-step explanation:
w=9h
H is a variable
9×hour= wage
9×15= $135
9×18= $162
157.50-135=$22.50
189-162=$27
27-22.50=4.50
Now cause its per hour we know she earns $4.50 more in 3 hours.
4.50÷3=$1.50
