It's 35 because 10 plus 5 is 15. You the subtract it by 50 and you get 35.
Answer:
∠ P = 40°
Step-by-step explanation:
Since PQ = PR then the triangle is isosceles and the base angles are congruent, then
∠ R = ∠ Q = 70° , so
∠ P = 180° - (70 + 70)° ← sum of angles in triangle is 180°
∠ P = 180° - 140° = 40°
Answer:
Step-by-step explanation:
This is a typical example where the Poisson distribution is a good choice to model the situation.
In this case we have an interval of time of 50 milliseconds as average time for the server to address one request and 50 requests per second.
By cross-multiplying we determine the expected value of requests every 50 milliseconds.
We know 1 second = 1,000 milliseconds
50 requests __________ 1000 milliseconds
x requests __________ 50 milliseconds
50/x = 1000/50 ===> x = 2.5
and the expected value is 2.5 requests per interval of 50 milliseconds.
According to the Poisson distribution, the probability of k events in 50 milliseconds equals
Let d represent the amount of money Donavon brought to the fair.
After spending half his money on rides, he had half of it left: d/2.
After spending $3 on food, he had left (d/2 -3).
Donavon and his 3 friends together had 4 times this amount. They had $8.
... 4(d/2 -3) = 8
_____
The solution can be found by simplifying the equation, adding the opposite of the constant on the left, then dividing by the coefficient of d.
... 2d -12 = 8 . . . . . eliminate parentheses
... 2d = 20 . . . . . . . add 12
... d = 10 . . . . . . . . divide by 2
Donavon and each of his friends brought $10 to the fair.
