1. Suppose that I'm flipping a dime and quarter, such that the probability that both are head is pi, both tail is P2, only the d

ime is head is p3, and only the quarter is head is 1- P1 – P2 - p3. The entropy (or randomness) of this two-coin-flip is H(P1, P2, P3) = -pı log2 (P1) – P2 log2 (P2) – P3 log2 (P3) – (1 – P1 – P2 - P3) log2(1 – P1 – P2 - P3). Calculate a H/Op1, and evaluate it at P1 = P2 = P3 = 0.25 and at pı = 0.7, P2 = P3 = 0.1. 2. Compute the Hessian of the following functions, and verify directly that the matrix is symmetric: (a) u(x, y) = y*exy, (b) v(x, y, s) = 114,22 3. I'm climbing a mountain, whose landscape is described by the function z(x, y) = e-(x++y). I'm at position (x, y) = (-1,1). What is the maximal slope at this point? What is the slope I'm climbing if I walk southwest?

Ramona went to a theme park during spring break. She was there for 7 hours and rode 14 rides. At what rate did Ramona ride rides
Tanzania [10]

Answer:

2 rides per hour

Step-by-step explanation:

This is a division problem since we would need to divide in order to answer the question.

Divide the amount of rides she rode to the number of hours she was there.

Input the numbers below:

amount of rides she rode/number of hours there

14/7=2

At this rate, Ramona rode 2 rides per hour.

What is the mean of 74, 88, 79, 70, 74. Please help me!
maks197457 [2]

Answer:

77

Step-by-step explanation:

Add all the numbers together (74+88+79+70+74) then divide by the amount of numbers there are (in this case 5) So (74+88+79+70+74=385) (385/5=77)

License plates in a particular state display 3 letters followed by 3 numbers. How many different license plates can be manufactu
netineya [11]

Using the fundamental counting theorem, it is found that 17,576,000 different license plates can be manufactured.

Fundamental counting theorem:

States that if there are n things, each with n_1, n_2, \cdots, n_n ways to be done, each thing independent of the other, the number of ways they can be done is:

N = n_1 \times n_2 \times \cdots \times n_n

In this problem:

  • Since repetition is allowed, for the 3 letters, there are 26 outcomes, hence n_1 = n_2 = n_3 = 26.
  • For the 3 numbers, there are 10 outcomes, hence n_4 = n_5 = n_6 = 10

Then:

N = 26^3 \times 10^3 = 17576000

17,576,000 different license plates can be manufactured.

Eddy is going to multiply a whole number greater than zero by 10.  Which sentence is true about the product?
Semmy [17]
The sentence that is true should have something to do with that 10 multiplied by any number is the number being multiplied by 10 with a zero at the end.
All numbers greater than 0 and smaller than 10 multiplied by 10 and their products are
1×10=10
2×10=20
3×10=30
4×10=40
5×10=50
6×10=60
7×10=70
8×10=80
9×10=90
I hope this helps

What is the slope of the line that passes through the points (3, 8) and (12, 1)?
STatiana [176]
Slope forumla is:
(y2-y1)\(x2-x1)

so, (1-8)\(12-3) or -7\9. I see that 7/9 is in your answer list twice, so whichever is negative is your answer
