1500 is your answer hope it helps
Answer:
a
Step-by-step explanation:
its obvious
Mean means to average. in order to average, add all the numbers then divide by how many numbers you have.
All these ages add up to 150. because there are 7 ages, divide by 7. this is 21.4 which can be rounded to about 21
46 + 48 + 21 + 12 + 15 + 8 = 150
150 ÷ 7= 21.4285 = 21
The point Q will satisfy the equation y=-2x+3 if the coordinates are plugged into the equation, so we plug in our known coordinate of the point Q (y = 3) and then we solve for x:
3 = -2x + 3
subtract 3 from both sides
0 = -2x
divide both sides by -2
x = 0
so the coordinate Q is (0,3)
