1. y=4x
2. (I am not able to graph it, but here are some points on the line.)
(0,3) (3,6) (5,8) those three should get you to graph a line. When you have these types of problems, make a table. plug in random numbers, that are reasonable, usually 1-6, and plug them into the equation and enter your new y values, then graph the ordered pairs and connect them.
Answer:
ask me a real question
Step-by-step explanation:
Answer:
Yes, result is significant ; PVALUE < α
Step-by-step explanation:
Given :
x = 536
n = sample size = 1012
Phat = x / n = 536 / 1012 = 0.5296 = 0.53
H0 : P0 = 0.5
H1 : P0 > 0.5
Test statistic :
(Phat - P0) ÷ sqrt[(P0(1 - P0)) / n]
1-P0 = 1 - 0.5 = 0.5
(0.53 - 0.5) ÷ sqrt[(0.5*0.5)/1012]
0.03 ÷ 0.0157173
= 1.9087
Pvalue :
Using the Pvalue from test statistic :
Pvalue = 0.02815
To test if result is significant :
α = 0.05
0.02815 < 0.05
Pvalue < α ; Hence, result is significant at α=0.05; Hence, we reject H0.
-6p < 12 Divide -6 on both sides to get "p" by itself
p > -2
When you divide or multiply a negative number to both sides of the inequality, the sign (< , > , ≤ , ≥) is flipped.
