Answer:

x=3, 5, 4, 4, 3

Step-by-step explanation:

Given:

Starting at a fixed time, each car entering an intersection is observed to see whether it turns left (L), right (R), or goes straight ahead (A) such that the experiment terminates as soon as a car is observed to turn left.

X = the number of cars observed

For outcome RRL,

experiment terminates after the third car, so, X = 3

For outcome AARRL,

experiment terminates after the fifth car, so, X = 5

For outcome AARL,

experiment terminates after the fourth car, so, X = 4

For outcome RRAL,

experiment terminates after the fourth car, so, X = 4

For outcome ARL,

experiment terminates after the third car, so, X = 3

A triangle has sides with lengths of 12 kilometers, 35 kilometers, and 37 kilometers. Is it a right triangle?
quester [9]

Answer: yes

Step-by-step explanation:

Using Pythagorean theorem WHICH ONLY WORKS FOR RIGHT TRIANGLES,

a^2+b^2=c^2 where a and b are the two shortest legs.

12^2+35^2=c^2

144+1225=c^2

c^2=1369

Help plz!!!! This is precal
sashaice [31]

Answer:

The remainder is 0 ⇒ 3rd answer

Step-by-step explanation:

* In the synthetic calculation we use the coefficient of the dividend

  with the value of x when the divisor = 0

∵ x - 1 = 0 ⇒ add 1 to both sides

∴ x = 1  

Step 1 : Write down the coefficients of the f(x) , put x = 1 at the left  

                         1        1     0     -1     1     -1    

                                ________________

Step 2 : Bring down the first coefficient to the bottom row.

                        1         1      0    -1     1    -1    

                               ________________

                                   1

Step 3 : Multiply it by 1, and carry the result into the next column.

                       1         1      0    -1     1    -1    

                               ____ 1_________

                                  1  

Step 4 : Add down the column

                       1        1       0    -1     1    -1    

                                ____1__________

                                 1      1

Step 5 : Multiply it by 1, and carry the result into the next column

                       1        1      0     -1     1     -1    

                              _____1___1_______

                                 1       1

Step 6 : Add down the column

                      1         1       0    -1      1     -1    

                                ____1___1______

                                 1       1      0

Step 7 : Multiply it by 1, and carry the result into the next column

                    1        1       0    -1      1     -1    

                               ___1___1___0______

                              1      1      0

Step 8 : Add down the column

                    1         1     0      -1      1      -1  

                          _____1____1__0_____

                              1      1       0      1

Step 9 : Multiply it by 1, and carry the result into the next column

                  1         1     0      -1       1      -1  

                          ____1____1___0___1___

                            1     1        0      1        

Step 10 : Add down the column

                  1         1     0      -1       1      -1  

                          ____1____1___0___1___

                            1     1        0      1         0

∴ The quotient is (x³ + x² + 1 ) and the remainder is 0

* The remainder is 0

Zachary is 1 year older than his sister, Nicole. Jaycob is
shtirl [24]

Answer:

Zachary is 9, Nicole is 8, and Jaycob is 27.

Step-by-step explanation:

x=Zachary

y=Nicole

z=Jaycob

x+y+z=44

x*3=z

x-1=y

However, for now, let's just assume that  x and y are actually the same, and that the answer is actually 45.

so, x*3=z, and y*3 also equals z.

This is so that technically, 45/5=x, because z accounts for 3, and both x and y account for 1 each, meaning altogether it should be 5 you should be dividing by. 45/5=9, so x=9. Now that we have that figured out, we can solve the rest easily. 9-1=8, so there's your y, and 9*3=27. 27+9=36, and 36+8=44.
