Answer:
1/2
Step-by-step explanation:
There are 6 sides on a number cube, each labeled with 1,2,3,4,5, and 6.
Out of these, 2,3, and 5 are odd numbers. That's 3.
Probability is the (number of ways the event can occur)/(total number of possible outcomes)
So 3/6=1/2
Complete question is:
Seventy million pounds of trout are grown in the U.S. every year. Farm-raised trout contain an average of 32 grams of fat per pound, with a standard deviation of 7 grams of fat per pound. A random sample of 34 farm-raised trout is selected. The mean fat content for the sample is 29.7 grams per pound. Find the probability of observing a sample mean of 29.7 grams of fat per pound or less in a random sample of 34 farm-raised trout. Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places.
Answer:
Probability = 0.0277
Step-by-step explanation:
We are given;
Mean: μ = 32
Standard deviation;σ = 7
Random sample number; n = 34
To solve this question, we would use the equation z = (x - μ)/(σ/√n) to find the z value that corresponds to 29.7 grams of fat.
Thus;
z = (29.7 - 32)/(7/√34)
Thus, z = -2.3/1.200490096
z = -1.9159
From the standard z table and confirming with z-calculator, the probability is 0.0277
Thus, the probability to select 34 fish whose average grams of fat per pound is less than 29.7 = 0.0277
Answer:
it can be 5 from my side is that right
Answer:
-4/15d-8
Step-by-step explanation:
2/5(d-10)-2/3(d+6)
2/5d-20/5-2/3d-12/3
2/5d-2/3d-20/5-12/3
2/5d-2/3d-4-4
6/15d-10/15d-8
-4/15d-8
For this type of problem, remember to combine like terms and simplify the answer at the end.
