Its would need to be 4 foot which makes a 90 degree angle and the top would have to be at a 35 degree angle i think
Yes it is a function Bc the x values don’t repeat
If you would like to know how many hours did Eric practice the piano this week, you can calculate this using the following steps:
the piano: 3/4 of 8 hours = 3/4 * 8 hours = 6 hours
The correct result would be 6 hours.

Answer:
(115.2642, 222.7358).
Step-by-step explanation:
Given data:
type A: n_1=60, xbar_1=1827, s_1=168
type B: n_2=180, xbar_2=1658, s_2=225
n_1 = sample size 1, n_2= sample size 2
xbar_1, xbar_2 are mean life of sample 1 and 2 respectively. Similarly, s_1 and s_2 are standard deviation of 1,2.
a=0.05, |Z(0.025)|=1.96 (from the standard normal table)
So 95% CI is
(xbar_1 -xbar_2) ± Z×√[s1^2/n1 + s2^2/n2]
=(1827-1658) ± 1.96×sqrt(168^2/60 + 225^2/180)
= (115.2642, 222.7358).
