Complete question:
One classical experiment on ESP (extrasensory perception) tests for telepathy between two participants by using five cards with different designs, all known to both participants.For each trial, the “sender” participant sees a randomly chosen card and concentrates on its design. The “receiver” attempts to guess the identity of the card.<span>Assume that each of the five cards is equally likely to be chosen.
</span>Out of 10 trials, a receiver got four cards correct. What is her success rate?<span>What is her expected rate of success, assuming she is only guessing?
answer:
</span>Success rate = 4/10 = 40%
<span>Expected success rate = 1 out of 5 correct = 20%</span>
Square root of 99 is 9.94, points is 3.14, and 9.88888888 so it would be 9.94, 9.8888, points
Answer:
∠TUY = 120°
Step-by-step explanation:
There are two rules you can apply here:
1) The sum of the angles inside a triangle is 180°. This means that ∠SUT = 180° - 70° - 50 ° = 60°
2) A vector coming out of a line two angles between itself and the line, and they add up to 180° as well. This means that ∠TUY = 180° - ∠SUT. So ∠TUY = 180° - 60° = 120°
So the missing angle one hundred and twenty degrees.
Answer:
x = -2 and y = 2
Step-by-step explanation:
We have the following system of linear equations;
y=x+4
y=-2x-2
To solve the above system, we shall be equating the right hand sides of the two equations since we have y's on the left hand side of both equations;
x + 4 = -2x - 2
add 2x on both sides of the equation;
x + 4 + 2x = -2x - 2 + 2x
3x + 4 = -2
subtract 4 on both sides of the equation;
3x + 4 - 4 = -2 - 4
3x = -6
x = -2
We can use the first equation y=x+4 to determine the value of y;
y = -2 + 4
y = 2
The solution to the system of linear equations is thus;
x = -2 and y = 2
