Write out the ratio. 12/x=4/6. From here you can see that to get from 12 to 4, you divide by three. To find x, multiply 3 to 6. Your answer is 18 inches.
3 blue, 2 red, 5 white........total of 10 sweaters
probability that red is picked first : 2/10 reduces to 1/5
replace
probability of second pick being white : 5/10 reduces to 1/2
replace
probability of third pick being blue : 3/10
probability of all of this happening : 1/5 * 1/2 * 3/10 = 3/100 <==
To find the average you add both of the numbers together and then divide by the number of numbers if that makes sense so 545 + 777 divided by 6 = 674.5
Answer:
Step-by-step explanation:
This is a hypothesis testing of single mean with population mean.

(One tailed test)
Sample mean = 460.4 and n = 36 and s = 101.9 oz
Alpha = 0.05
Mean diff = 37.4 and std error = 101.9/sqrt 36 = 16.98
Test statistic t = mean diff/se = 2.20
p = 0.01725
Since p <0.05 reject H0.
