First you see how it goes up 6 each time this is the start of your nth term rule
6n
Then -6 from the first term to get the ‘0th term’ 1-6=-5
So nth term rule is
6n-5
hope this helps
Answer:
The expected number of students to prefer summer=245
Step-by-step explanation:
Step 1
Determine the number of students that prefer summer as their favorite season, and the sample size
number that prefer summer=7
sample size=10
Step 2
Determine the probability of a student picking summer as their favorite season as shown;
Probability=number that prefer summer/sample size
Probability=7/10=0.7
Step 3
Determine the total number of students out of the total population that can be expected to prefer summer as follows;
Expected number of students=probability×total number of students
where;
probability=0.7
total number of students=350
replacing;
Expected number of students=(0.7×350)=245
The expected number of students to prefer summer=245
