Answer:
We are 90% sure that the true proportion of Americans who approve the ppresident's policies is in the interval from 42% to 46%.
Step-by-step explanation:
A confidence interval of a proportion p% at the x% level with m% margin of error means that:
We are x% sure that the true mean of the population is in the interval from (p-x)% to (p+x)%.
In this problem, we have that
90% confidence level
44% with a margin of error of 2%
So:
We are 90% sure that the true proportion of Americans who approve the ppresident's policies is in the interval from 42% to 46%.
Answer:
x = -49
Step-by-step explanation:
The sum of the angles of a triangle is 180°. Set up the following equation and solve for x.
Answer: The answer would be 73.6
Step-by-step explanation: We have to 32x2.3 to get 73.6.
Hope this helps!
a)
F = (K - 273.15) + 32
<u>- 32</u> <u> - 32</u>
F - 32 = (K - 273.15)
(F - 32) = [(K - 273.15)]
(F - 32) = K - 273.15
- = K - 273.15
- 57.6 = K - 273.15
<u> + 273.15</u> <u> + 273.15 </u>
- 215.55 = K
b)
- 215.55 = K
324 - 215.55 = K
108.45 = K
