S is the set of prime numbers that are less than 15. The correct solution in roster form is {1,3,5,7,9,11,13}. The answer is letter C. The rest of the choices do not answer the question above.
11/29 i believe. Cuz you add them all together and get 29 and then red and green added together is 11
The top part of the shape is 8x6 and the bottom part is 6x6 so the answer is 84
Complete question :
The GPAs of all students enrolled at a large university have an approximately normal distribution with a mean of 3.02 and a standard deviation of .29.Find the probability that the mean GPA of a random sample of 20 students selected from this university is 3.10 or higher.
Answer:
0.10868
Step-by-step explanation:
Given that :
Mean (m) = 3.02
Standard deviation (s) = 0.29
Sample size (n) = 20
Probability of 3.10 GPA or higher
P(x ≥ 3.10)
Applying the relation to obtain the standardized score (Z) :
Z = (x - m) / s /√n
Z = (3.10 - 3.02) / 0.29 / √20
Z = 0.08 / 0.0648459
Z = 1.2336940
p(Z ≥ 1.2336) = 0.10868 ( Z probability calculator)
