Answer:
B. -4^11 just got it right
2nd part is 6
3rd part is C. 6^14
Step-by-step explanation:
Answer:
x = 15
Step-by-step explanation:
There are theorems regarding Property of Similar polygons.
Corresponding sides are in proportion.
triangle ABE is similar to triangle ACD
so
AB:BC = AE: ED
x:10 = 9:6
(x/10) = (9/6)
x = 10*9/6 = 5*3 = 15
3.14 x 8^2 = 200.96 (divided by) 2 = 100.48
1/2 (8 x 12) = 48 x 2 = 96
100.48 + 96 = 196.48
A = 196.48
Answer:
well I cant see the full thing so just do length times width times height so just multiply everything
Answer:
Confidence interval = [ 0.4432, 0.4968]
Step-by-step explanation:
Registered voters approved of the job Barack Obama was doing as president,
p = 47% = 0.47
Total sample size, n = 2,294
Confidence level = 99%
now,
confidence interval for the proportion of all registered voters who approved of the job Barack Obama was doing as president
= p ±
for 99% confidence level, z value is 2.58
= 0.47 ±
= 0.47 ± 0.0268
or
Confidence interval = [0.47 - 0.0268, 0.47 + 0.0268 ]
or
Confidence interval = [ 0.4432, 0.4968]
