This year, John played in 10 baseball games. In these games he had hit the ball 2,3,1,1,3,2,4,6,2, and x times. The mean is 3 hi
allsm [11]
Answer:
x = 3
Step-by-step explanation:
The mean is the average so set up an equation that adds up all the points and divides them by the total, set equal to 3, and solve for x
(2+3+1+1+3+2+4+6+2+x)/10 = 3
(24 + x)/10 = 3
24 + x = 30
x = 6
To check if this is correct, add up all the numbers and divide by 10.
2+3+1+1+3+2+4+6+2+6 = 30/10 = 3
The answer is definitely 6
Answer:
$30
Step-by-step explanation:
Let 6 cans represent an "order" of fruit juice. 72 cans means 12 orders (72 divided by 6). Since each order costs $2.50, 12 orders costs $30 (12 multiplied by 2.5).

Height of the flag pole is 16.2 ft
Answer:
y = 10
rate of change = 5
Step-by-step explanation:
The initial value is the beginning output value, i.e. the y-value when x = 0
Therefore, the initial value is y = 10
rate of change = change in y ÷ change in x
⇒ rate of change = (40 - 30) ÷ (6 - 4)
= 10 ÷ 2
= 5
