Answer:
30x+12
Step-by-step explanation:
distribute 6 into (2x+1) and 3 into (6x+2) basically multiply
12x+6+18x+6
combine like terms
12x+18x=30x
6+6=18
hope this helps
Yes, the sampling distribution is normally distributed because the population is normally distributed.
A sampling distribution is a chance distribution of a statistic obtained from a larger variety of samples drawn from a specific populace. The sampling distribution of a given population is the distribution of frequencies of a variety of various outcomes that would probable occur for a statistic of a populace.
A sampling distribution is a probability distribution of a statistic this is obtained via drawing a huge variety of samples from a particular populace. Researchers use sampling distributions so that you can simplify the technique of statistical inference.
Solution :
mean = μ40
standard deviation σ σ= 3
n = 10
μx = 40
σ x = σ√n = 3/√10 = 0.9487
μ x = 4σ\x = 0.9487
σx = 0.9487
Yes, the sampling distribution is normally distributed because the population is normally distributed.

Answer:
Probability of obtaining 6H and 4T = 0.2051
Step-by-step explanation:
Since for a fair coin,
Probability of obtaining Head = 0.5
p = 0.5
q = 1-p = 0.5
Probability of obtaining 6H and 4T = 10C6 (p)^6(q)^4 = 210*0.5^6*0.5^4
P(6H, 4T) = 0.2051
