Answer:
-18
Step-by-step explanation:
2x²-7xy+3y²
2(3²)-7(3)(4)+3(4²)
2(9)-84+3(16)
18-84+48
18+48-84
-18
Answer:
C) Yes, because the joint probability of P and M is equal to 0.
Step-by-step explanation:
Given that, P represents the event that the selected person preferred pepperoni only.
And M represents the event that the selected person preferred mushroom only.
so, P and M are two mutually exclusive events because two events are mutually exclusive if they do not occur together.
Here, P and M cannot occur at same time.
so, the joint probability of P and M i.e) probability of both P and M to occur at same time is zero.
Answer:
Reading bar graphs (multi-step) In a bar graph each bar represents a number. The following bar graph shows the number of seconds that different rides last at the fair. We can tell how long each ride lasts by matching the bar for that ride to the number it lines up with on the left.
Here is an example:

Determine the concentration at the end of 4 hours
First, calculate the amount of liquid that has been replaced at the end of the 4 hours.




This implies that, over the 4 hours; The tank has 160000 liters of liquid out of 440000 liters were replaced
Calculate the ratio of the liquid replaced.




Next, calculate the amount of solid left.




Lastly, the concentration is calculated as:


Convert L to cubic meters



Answer:
midpoint = (-2.5 , - 10)
Step-by-step explanation:
midpoint =( ((x1 + x2)/2) , ((y1+y2)/2)) )
= ( ((-2 + -3)/2) ,(( -8 + -10)/2) )
= ( -2.5 , -10)
