6.9 = 6.9 / 1
Numerator = 6.9 × 10 = 69
Denominator = 1 × 10 = 10
Numerator / Denominator = 69 / 10
Simplifying our fraction
= 69/10
= 69/10
= 6 9/10
Step-by-step explanation:
∫₀³⁰ (r/V C₀ e^(-rt/V)) dt
If u = -rt/V, then du = -r/V dt.
∫ -C₀ e^u du
-C₀ ∫ e^u du
-C₀ e^u + C
-C₀ e^(-rt/V) + C
Evaluate between t=0 and t=30.
-C₀ e^(-30r/V) − -C₀ e^(-0r/V)
-C₀ e^(-30r/V) + C₀
C₀ (-e^(-30r/V) + 1)
I got the same answer. Try changing the lowercase v to an uppercase V.
Answer:
The question has a missing part and here it the complete question:
Imagine each letter of the word “Mathematical” is written on individual pieces of paper and placed in a bag. Should you pick a random letter from that bag, what is the probability that you pick a vowel?
Answer: 5/12
Step-by-step explanation:
The question asks for the probability of picking a vowel.
From the word 'Mathematical', we have a total of 12 letters and a total of 5 vowels (a,e,a,i,a).
Probability of picking a vowel = Total number of times the event(vowel) occurs/total number of possible outcomes(total letters)

Answer:
A collection of short stories.
Step-by-step explanation:
A classic novel is almost always fiction, which is not suitable for referencing. A commercial website publicly advertises its products or services. Again, not professionally referenceable. This leaves us with a collection of short stories. This option is correct because the stories come from realistic and personal accounts.

What is Maintenance rehearsal?</h3>
Maintenance rehearsal is a rehearsal technique that involves straight repetition of data values or information(s) to memorize and remember them.
This rehearsal technique is often referred to as rote rehearsal. The repetition of the digits of a phone number by Alex again and again while he is getting out his phone to enter it into his contacts is an example of maintenance rehearsal.
