Answer:
33
Step-by-step explanation:
49-15=34
34/17=2
For this sequence, you can write this function:
f(x)=15+2(x-1)
Check:
f(18)=15+2(18-1)
f(18)=15+2(17)
f(18)=15+34
f(18)=49
So:
f(10)=15+2(10-1)
f(10)=15+2(9)
f(10)=15+18
f(10)=33
Multiplying both sides by 3, we get (3/9)*(2m-16)=(2m+4). Next, we multiply both sides by 9 and expand to get 6x-48=18m+36. Subtracting 6x and 36 from both sides, we get 12x=-48-36=-84. After that, we divide both sides by 12 to get m=-7
Question 4- is 32.25
question 5- is 12.4
question 6 -is 14/17
question 7 - is 10.7
Answer: the smallest number of people required for the sample to meet the conditions for performing inference is 100
Step-by-step explanation:
Given that;
36% of US population has never been married
32% are divorced
27% are married
5% are widowed
Taking a simple random sample of individuals to test this claim;
we need expected count in each cell to be at least 5, here the smallest proportion is 5% = 0.05
so we only need to satisfy condition for its expected count;
n × 0.05 ≥ 5
n = 5 / 0.05 = 100
Therefore the smallest number of people required for the sample to meet the conditions for performing inference is 100
