We need to test the hypotheses:
The confidence interval for proportion is
.
Here
The z value to be used is 1.96.
The 95% CI is
.
Since 0.5 lies in the interval (0.488,0.543), we cannot reject the null hypothesis with 95% confidence.
Data table for y = 5x³ - 3
Plug in the x to find the y-values.
x -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6
y -1083 -628 -323 -138 -43 -8 -3 2 37 132 317 622 1077
Use the folumla AB^2 = BD * (CD + BD)
fill in the known numbers:
AB^2 = 12 x (15 +12)
AB^2 = 12 x 27
AB^2 = 324
AB = SQRT(324)
AB = 18
Answer:
The graph of x=4 is a vertical line parallel to y-axis and having a x-intecept:(4,0) and having no y-intercept
Step-by-step explanation:
So I think that the answer would be this, which means answer 1!! Hope this helps
