Answer:
4.4
Step-by-step explanation:
The sum of the probabilities of all possible outcomes is 1.
As the die is loaded so that the number 4 occurs 3/10 of the time, and the other numbers occur with equal frequency, then the probability of numbers 1, 2, 3, 5, 6, 7 and 8 being rolled is 1/10.
Create a probability distribution table for X, where X is the score on the loaded 8-sided die:
Add a product row and a totals column:
(The Product is row is the product of the <u>score on the die</u> and <u>its probability</u>).
The expected value (EV) is the sum of the product of each outcome and its probability.
Therefore, the expected value (EV) of this die is 44/10 = 4.4
((10^x)^3)+4=129 subtract 4 from both sides
((10^x)^3)=125 to cancel out the 3rd power, cube root both sides
∛((10^x)^3)=∛125
10^x=5 use logarithms where 10 is the base (cant figure out how to write it in)
log5 = x plug into calculator log5
x=0.69897
Answer:
false is the correct answer right
Answer:
Step-by-step explanation:
I don't know where you are in your class, or even what chapter you are in, but I solved this using a right triangle.
We don't need to know the angles, just the sides.
c is the hypotenuse, the line at a tilt
b is the adjacent line, directly below c
a is the opposite line
c = 13
a= 12
b = ?
In order to find b, we use the Pythagorean Theorem, , but we need to rearrange the problem to where we are solving for b instead of c,
So, b = 17.69
Now, we need to evaluate each of the trig. functions:
So, there is your answers, hope that is what you are looking for.
