Answer:
a)%85,5
b)%92,2
Step-by-step explanation:
a) To determine the probability of getting a hand with at least one face, we need to calculate the probability of the hand without any face firstly.
Then, we need to deduct this value from the probability 1
The probability of the hand with at least one face is %85,5.
b)To determine the probability of a hand with at least one ace and face we will track the same road again.
Then, we need to deduct this value from the probability 1
The probability of the hand with at least one ace and one face is %92,2.
Answer:
b=2
c=-24.01
Step-by-step explanation:
If I understood your question right you need to find the constants b and c in the polynomial:
such that:
In order to get a system of two equations you can find limes when x goes to 4 from the right side or from the left side.
I solved this using a number that is close to 4. When it goes from right I used 4.1 and from left 3.9. This way you get two equations:
When you solve the system you get the answers above.
Answer:
x = -1, y = 2 and z = -4.
Step-by-step explanation:
-2x + 5y + 4z = -4 ......(A)
-5x - y + z = -1 .............(B)
2y + 2z = -4..................(C) Multiply (A) by 5 and (B) by -2:
-10x + 25y + 20z = -20 ....(D)
10x + 2y - 2z = 2 ..............(E) Adding D + E:
27y + 18z = -18 Dividing by 9:
3y + 2z = -2 ............(F) Subtract: (C) - (F):
-y = -2
y = 2.
Substitute for y is (C):
4 + 2z = -4
2z = -8
z = -4.
Substitute for y and z in (A):
-2x + 5(2) + 4(-4) = -4
-2x = -10 + 16 - 4 = 2
x = -1.
Answer:
17
Step-by-step explanation:
Pythagorean theory baby! Okay so the Pythagorean theory is a² + b² = c² so lets draw a triangle and label our sides. So we know 8² + 15² = c² so I'm going to find the square root of all of our numbers. We get 64 + 225 = c² so then add 64 + 225 = 289 then I take the square root of 289 which equals 17 . This answer also makes sense because out hypotenuse should always be bigger then the legs.
I'm pretty sure thats right, Hope this helps.
