Answer:
Complementary
Step-by-step explanation:
To be complementary, your two angles need to add up to 90 degrees
a right triangle is already 90 degrees so if you cut it through the middle they'd form complementary angles
To be complementary rwo angles need to add up to 90.
If we cut a right angled triangle we will get complementary angles.

The probability of a customer buying carrots is 11.4 percent.
We can use the following formula to calculate the probability of event A happening given that event B has already happened:
P(A | B) = P(A and B) / P(B)
Where:
P(A | B) is the probability of event A happening given that event B has already happened
P(A and B) is the probability of both event A and event B happening
P(B) is the probability of event B happening
In this case, event A is buying carrots and event B is buying apples or carrots.
We know that the probability of buying apples or carrots is 17 percent. We also know that the probability of buying apples and carrots is 5 percent. Therefore, the probability of buying carrots is:
P(carrots) = P(carrots and apples or carrots) / P(apples or carrots) = 5 percent / 17 percent = 11.4 percent
Therefore, the answer is d. 11.4 percent.

Answer:
C. 10.0 percent
Step-by-step explanation:
P(A) = 0.12
P(A\cap C)=0.05
P(A\cup C)=0.17=P(A)+P(C)-P(A\cap C)
0.17=0.12+P(C)-0.05
P(C)=0.17-0.12+0.05=0.10

40 minutes
Step-by-step explanation:
We have a load and a discharge, given by a speed that would be a barrel / minute.
Which means that the loading rate is: 1/20
And the discharge rate: 1/40
Since they are contrary, the result would be the subtraction between these two rates:
1/20 - 1/40 = 1 / x
1 / x = 0.025
x = 1 / 0.025
x = 40
Which means it will take 40 minutes to fill under the mentioned conditions

Answer:
Option D. (120, 80, 40)
Step-by-step explanation:
Let the cost of 3 baseball cards bought by Andrew are $x, $y and $z.
Now we will form the equations to find the unknown values of x, y, and z.
Statement 1 - Andrew bought 3 baseball cards for $240
Equation will be (x + y + z) = 240 --------(1)
Statement 2 - Jack offered a deal to buy the first card for the double of its original value along with the second card for $320.
Equation will be 2x + y = 320 --------(2)
Statement 3 - Jack offered another deal to buy first card for the double of its original value along with third card for $280
Equation formed 2x + z = 280 ------(3)
Now we can solve these equations to get the values of x, y and z.
From equation 2
y = 320 - 2x
From equation 3
z = 280 - 2x
Now we can replace the values of y and z in equation number 1.
Equation 1 becomes after substitution of y and z values
x + (320 - 2x) + (280 - 2x) = 240
Now we will group the similar terms
(x - 2x - 2x) + (320 + 280) = 240
-3x + 600 = 240
-3x = 240 - 600
-3x = - 360
x =
x = 120
Now we put x = 120 in the value of y
y = 320 - 2x
y = 320 - 2×120
= 320 - 240
= 80
Similarly we put the value x = 120 in value of z
z = 280 - 2x
= 280 - 2×120
= 280 - 240
= 40
So the original values of 3 baseball cards are (120, 80, 40)
Option D. will be the answer.
