Answer: (53.49%, 62.51%)
Step-by-step explanation:
Given : A poll found that 58% of U.S. adult Twitter users get at least some news on Twitter.
i.e. p= 0.58
The standard error for this estimate was 2.3%
i.e. S.E.=0.023
Critical value for 95% confidence : 
Confidence interval : 
i.e. 
Conclusion : We are 95% confident that the true population proportion of U.S. adult Twitter users who get some news on Twitter falls in interval (53.49%, 62.51%)
Answer:
The number is 448.
Step-by-step explanation:
Hope it helps
Given => PQ = 9 unit
PR = 7 unit
QR = 8 unit
To find => Area of triangle PQR
We can find area of triangle by Heron's Formula.
Where,
s = (9+7+8)/3
= 24/3
= 8
and,
a = 9
b = 7
c = 8
Heron's Formula =
=
=
=
=
Area of triangle = 2i√2 units
Hope this helps!
Area is base times height, 0.3 times 0.35 is 0.105. Hope this helps!!!
Idk but it can't be 10 or 9.7 bc a triangle's hypotenuse is always longer than its legs
