Answer:
Option D. 3g=21
Step-by-step explanation:
Let
g -----> the number of games
we know that
The number of games multiplied by 3 tickets to play a game must be equal to 21 tickets
so
The linear equation that represent this problem is
solve for g
Divide by 3 both sides
Answer:
p1.....area=lb=9×6=54in^2
p2....area=1/2bh
=14×9/2=7×9=63in^2
Answer:
1667
Step-by-step explanation:
(Margin of Error)² = (z × 0.5)²/n
Where n = number of samples
Minimum number of samples formula = (z × 0.5)²/ (Margin of Error)²
From the above question:
Margin of Error = 0.024
z = z score of a 95% confidence interval = 1.96
Minimum number of samples
= (1.96 × 0.5)²/(0.024)²
= 0.9604/(0.024)²
= 1667.3611111
Approximately to the nearest whole number = 1667
Therefore, the minimum number of samples is 1667
Answer:
Step-by-step explanation:
X F(X)
0 ⇒ -2(0) + 3 = 3
1 ⇒ -2(1) + 3 = 1
2 ⇒ -2(2) + 3 = -1
3 ⇒ -2(3) + 3 = -3
Answer:
- x ≥ -3
- x ≥ -3
Step-by-step explanation:
-15x + 60 ≤ 105
-15x ≤ 45
x ≥ -3
14x + 11 ≤ -31
14x ≤ -42
x ≥ -3
Best of Luck!
