Answer:
Number of different selection = 50C6
Number of different selection = 50 x 49 x 48 x 47 x 46 x 45
Number of different selection = 15 890 700
Step-by-step explanation:
Given that the cost of b burgers and h hot dogs is given by 3.25b + 2h.
Therefore, the cost of 4 burgers and 6 hot dogs is given by 3.25(4) + 2(6) = 13 + 12 = $25.
So,
We know that a * 1 = a.
Obviously, a times any quantity greater than 1 will result in a larger (or smaller, in the case of integers) number.
So 0.4 * 1.8 > 0.4.
I think the answer is chunking.
This is due to effect of chunking because chunking is basically the multi-store memorizing method.
First, to find out the number of students who scored below Amanda, we must find the z-score value of Amanda's score using the formula below.

where Z is the z-score, Χ is the expected average value, μ is the mean of Χ, and δ is the standard deviation. Thus, we have


Thus, using the z-table, we have P(Z<0.90) = 0.8159. Since we have wanted to find the number of students who scored below Amanda, then from the whole, we have (1 - 0.8159) = 0.1841. That means, out of 1000 students, 0.1841 of them scored below Amanda. Thus, we have (0.184)(1000) = 184.
Answer: 184 students
