The contents of seven similar containers of sulfuric acid are 9.8, 10.2, 10.4, 9.8, 10.0, 10.2, and 9.6 liters. find a 95% confi

Kamila [148]

The confidence interval is from 9.81 to 10.19.

We first find the mean of the data:

(9.8+10.2+10.4+9.8+10.0+10.2+9.6)/7 = 10

Next we find the standard deviation:
σ=√([(9.8-10)^2+(10.2-10)^2+(10.4-10)^2+(9.8-10)^2+(10-10)^2+(10.2-10)^2+(9.6-10)^2]/7) = 0.262

The z-score for 95% confidence is found by
1-0.95 = 0.05; 0.05/2 = 0.025; from the z-table, it is 1.96.

The confidence interval is calculated using
 $x\pm z\times (\frac{s}{\sqrt{n}})
\\
\\10 \pm 1.96(\frac{0.262}{\sqrt{7}})=10\pm 0.1941$

A theater can seat 273 people. The number of rows is 8 less than the number of seats in each row. How many rows of seats are the

artcher [175]

R * s = 273
r = s - 8.....s = r + 8

r(r + 8) = 273
r^2 + 8r = 273
r^2 + 8r - 273 = 0
(r - 13)(r + 21) = 0

r - 13 = 0
r = 13

r + 21 = 0
r = -21.....extraneous solution...not ur answer

r = 13
s = r + 8 = 13 + 8 = 21

so there are 13 rows.....each row containing 21 seats

D(4 units right, 2 up)

Step-by-step explanation:

You must pick a point which does not have an apostrophe. Then you see how which direction is goes (e.g left or right) and then you see the height (up and down) and combining all this the answer would be 4 units right, 2 up
