A pie is a baked treat, filled with fruit or other stuff, usually in a round dish with a pastry crust.
Pi is a letter in the Greek alphabet, small letter π and capital letter
In math the small letter π is the circle constant, the ratio of a circle's circumference to its diameter. In a plane, that ratio is constant no matter the size of the circle. π = 3.14159...
In number theory π(x) is the prime counting function, the number of primes less than or equal to x. It has nothing to do with the circle constant.
Capital Pi is used as the product sign. It's like capital Sigma, the summation sign, expect it means multiply not add:
In your question they're probably referring to π the circle constant, so write pi is the ratio of a circle's circumference to its diameter.
Euler was the greatest, but he chose the wrong constant as the circle constant. A better value would be what we think of as 2π, the ratio of a circle's circumference to its radius, and the full 360 degrees.
Answer:
Step-by-step explanation:
Hello!
The variable of interest is
X: speed of a vehicle along a stretch of I-10 (mph)
This variable has a normal distribution with mean μ= 81 mph and a standard deviation σ= 8 mph.
The speed limit in the said stretch is 65 mph.
You need to calculate the probability of picking a car at random and its speed be at most 65 mph, symbolically:
P(X≤65)
To reach the probability, you need to use the standard normal distribution. To standardize the value fo X you have to subtract the value of μ and then divide it by σ:
P(Z≤(65-81)/8)= P(Z≤-2.00)
Now you look for the corresponding probability in the table of the standard normal distribution, since the value is negative you have to use the left entry. The integer and first decimal numbers are in the first column and the second decimal number is in the first row.
P(Z≤-2.00)= 0.0228
I hope it helps!
Answer:
(6, -9)
Step-by-step explanation:
Our system of linear equations is:
6x + 2y = 18
-4x - 2y = -6
When we solve by elimination, we're essentially "eliminating" a variable so that we can solve for other more easily. Here, let's eliminate the y variable by adding the two equations together:
6x + 2y = 18
+ -4x - 2y = -6
____________
2x + 0y = 12
x = 12/2 = 6
Plug this back into one of the original equations to find y:
-4x - 2y = -6
-4 * 6 - 2y = -6
-24 - 2y = -6
-2y = 18
y = -9
The solution is (6, -9).
