Yes, 14 is correct.
15: 3^4 - 4
16: 7n - 6
17: n^2 / 8
18: 3n x 9
It is seen in the figure given that there are three triangles with sides equal to a = 17 inches, b = 17 inches, and c = 20.5. Our angle c is the angle opposite side c and that is 74°. Using the equation given in the question,
A of triangle = ((17 in)(17 in)(sin 74°))(1/2)
= 138.9 in²
Then, we multiply this area by 3 since there are 3 triangles.
total area = (138.9 in²)(3) = 416.7 in²
The area of the figure is most approximately equal to 417 in².
Answer:
the answer is D because it 27 i not a perfect square 25 and 36 were the correct numbers to chose and 25 was correct to evaluate
Well, it is a binomial variable as long as you limit the amount of people you ask to a certain number for every trial.
Also, you MUST record the data either as they choose Frigidaire or they didn't choose Frigidaire. It MUST be these two choices, or it isn't binomial.
Answer:
0.005 `; 0.00499 ;
No, because np < 10 ;
2000
Step-by-step explanation:
Given that:
Number of samples , n = 100
Proportion, p = x / n
p = 1 / 200
= 0.005
p = μ
Standard deviation of sample proportion :
σp = sqrt((p(1 - p)) / n)
σp = sqrt((0.005(1 - 0.005)) / 200)
σp = sqrt((0.005(0.995)) / 200)
σp = sqrt(0.004975 / 200)
σp = sqrt(0.000024875)
σp = 0.0049874
σp = 0.00499
np = 100 * 0.005 = 0.5
n(1 - p) = 100(1-0.05) = 95
Smallest value of n for which sampling distribution is approximately normal
np ≥ 10
0.005n ≥ 10
To obtain the smallest value of n,
0.005n = 10
n = 10 / 0.005
n = 2000
