Answer:
(- 3, 0 ) ; (3, 0 )
Step-by-step explanation:
The solutions are obtained when y = f(x) = 0
From the table y = 0 when x = - 3 and when x = 3
The solutions are (- 3, 0 ) ; (3, 0 )
Answer:
33%
Step-by-step explanation:
Divide 246 and 80 and move the decimal over twice and round.
We use the formula:
x± s <span>t_<span>(1−c)/2 / </span></span>√n = 5
(1 - c)/2 = (1 - 0.95) / 2 = 0.025
Using the t score calculator at this value, at the 95% confidence internval,
t = 0.5080, So
100 - 19(0.5080) / √n = 5
Solving for n
n = 97
a) 97
b) yes
