Answer:
Step-by-step explanation:
You are going to go below zero with this one and in oF that's going to be mighty cold.
61- 74 = - 13 degrees.
I lived in a place where, during winter, - 20 was consider time to start growing tropical fruit. So - 13 is not so very bad if you are used to it.
16.8-8.3=8.5
You round the numbers with decimals to their tenths place and then subtract normally.
Answer:
p-e< p < p+e
(0.061 - 0.025) < 0.061 < (0.061 + 0.025)
0.036 < 0.061 < 0.086
Step-by-step explanation:
Given;
Confidence interval CI = (a,b) = (0.036, 0.086)
Lower bound a = 0.036
Upper bound b = 0.086
To express in the form;
p-e< p < p+e
Where;
p = mean Proportion
and
e = margin of error
The mean p =( lower bound + higher bound)/2
p = (a+b)/2
Substituting the values;
p = (0.036+0.086)/2
Mean Proportion p = 0.061
The margin of error e = (b-a)/2
Substituting the given values;
e = (0.086-0.036)/2
e = 0.025
Re-writing in the stated form, with p = 0.061 and e = 0.025
p-e< p < p+e
(0.061 - 0.025) < 0.061 < (0.061 + 0.025)
0.036 < 0.061 < 0.086

4k² + 17k + 7 = 3k
<u> - 3k - 3k</u>
4k² + 14k + 7 = 0
x = <u>-(14) +/- √((14)² - 4(4)(7))</u>
2(4)
x = <u>-14 +/- √(196 + 112)</u>
8
x = <u>-14 +/- √(308)

x = -1.75 +/- 0.25√(77)
x = -1.75 + 0.25√(77) ∨ x = -1.75 - 0.25√(77)
