Probability of getting heads on first try is 1/2
probability of getting heads on 2nd try is 1/2
probability of getting both is : 1/2 * 1/2 = 1/4
These are both independent because 1 does not effect the other
Christopher needs to create so that his time spent will be the same as his current time, the equation could be: 2.4x = 1.2x + 15
I'm not sure if I got the question right, but:
2x+4y=12
2*(-2)+4*4=12
-4+16=12
12=12
Answer:
-7
-4/21
400
Because 13 times 7 is 91..so -7
-3/7÷9/4 becomes -3/7×4/9. Taking LCM and solving gives -4/21.
last is easy.it becomes (12÷3)×100=400
Answer:
$61
Step-by-step explanation:
Given
Number of days, x = 5
Expenditure per day, E'(x) = 10x + 11
Required
Determine the expenditure per day (E'(x))
From the question, we have that
Substitute 5 for x
Hence, the expenditure for 5 days is $61
