Answer:
<h2>
75 m²</h2>
Step-by-step explanation:
Six liters of paint will cover 50 square meters.
6L ⇒ 50m²
then,
1L ⇒ 50/6 m²
9L ⇒ 50 × 
m²
⇒ 75 m²

➷ As you can tell, the ratio of the lengths is 2 : 1 (the length of a is twice the length of b)
The ratio for area would be the squared version of the length ratio
2^2 = 4
1^1 = 1
The ratio for area is 4 : 1

Answer:
z = 188
Step-by-step explanation:
1. 10/13 = 8 - 2z/52 (simplify - 2z/52)
10/13 = 8 (- 1/26)*z
2. 10/13 = (- 1/26)*z + 8 (flip for ease in solving)
(- 1/26)*z + 8 = 10/13
3. (- 1/26)*z + 8 = 10/13 (inverse: subtract 8 from each side to isolate variable <em>z</em>)
(- 1/26)*z = 10/13 - (8*13)/(1*13) (common denominator needed for add/subtract)
(- 1/26)*z = - 94/13 (simplify)
4. (- 1/26)*z = - 94/13 (inverse: multiply both sides by -26/1 to isolate variable <em>z</em>)
<h2>z = 188</h2>
Answer:
Step-by-step explanation:
Given that an exit poll of 1000 randomly selected voters found that 515 favored measure A.
Sample proportion p = 
Margin of error 99% = 2.58*SE
=
99% confidence interval =
------------------------
(Right tailed test)
STd error = 
Test statistic Z = p diff/std error =
p value = 0.1714
