Answer:
3/12 is the same as 3 divided by 12
Answer:
105
Step-by-step explanation:
< 7 is also 105- they are alternate exterior angles
Answer:
If y = 105, x should be 15: x =15
Step-by-step explanation:
Unlikely because there are more snickers bars then twix bars, but there are still twix bars so it’s not impossible
Answer:
(0.4593, 0.5073)
Step-by-step explanation:
The first thing we must do is calculate p:
p = 580/1200 = 0.4833
now 90% confidence interval is given by:
p + - (z alpha / 2) * (p * (1-p) / n) ^ (1/2)
Now, at 90% confidence level the t is:
alpha = 1 - 90% = 1 - 0.90 = 0.10
alpha / 2 = 0.10 / 2 = 0.05
z (0.05) = 1.645
replacing these values we are left with:
p + - (1.645) * (0.4833 * (1- 0.4833) / 1200) ^ (1/2)
0.4833 + - 0.024
the interval would be:
0.4833 + 0.024 = 0.5073
0.4833 - 0.024 = 0.4593
(0.4593, 0.5073)
