Answer:
= 4n + 3
Step-by-step explanation:
Note there is a common difference d between consecutive terms, that is
d = 11 - 7 = 15 - 11 = 19 - 15 = 4
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = 4, thus
= 7 + 4(n - 1) = 7 + 4n - 4 = 4n + 3

Answer:
Answer is 8 9/10
We convert 'fifths' into 'tenths'
3/5 = (x2) = 6/10
Note 7/10 is more and 10/10 =1
We can predict their will be 9/10 after we subtract and do the sum.
12 6/10 - 3 7/10 = 8 9/10
Step-by-step explanation:
We redo with decimals
12.6 - 3.7 = 8.9 = 8 9/10
<span>you have to divide the numerator by the denominator.
-2 1/4 = -9/4 </span>
Binomial distribution because:
Trials are Bernoulli (affected or not)
Probability is known (p=0.05) and remains constant for all trials.
Number of trials is known (n=6).
P(x)=C(n,x)p^x*(1-p)^(n-x)
x=0 =>
P(0)=C(6,0)(0.05^0)(0.95^6)
=0.7351.... (approximately)
