Let: x = number of copies sold
We can formulate the following equation to solve for x:
1.50x - 0.9x - 600 = 0
x = 1000
Therefore, the club must sell 1000 copies to break even. Among the choices, the correct answer is A.
Answer:
<em>113.04</em>
Step-by-step explanation:
Using: A=πr squared, u do 3.14 times 6 squared, which gives u: 113.04!!
Answer:
Test statistic = 2.8965
Step-by-step explanation:
The test statistic is given by the formula
z = (x - μ)/σₓ
μ = mean = 0.799
x = proportion of literate people in Tamil Nadu = (983/1185) = 0.8295
σₓ = standard error of this calculated proportion = √[p(1-p)/n]
= √(0.8295 × 0.1705/1185) = 0.01093
z = (x - μ)/σₓ
z = (0.8295 - 0.799)/0.01093 = 2.8965
z = 2.8965
Hope this Helps!!!
Answer:
x = 10
z = 116°
Step-by-step explanation:
By the definition of supplementary angles, we have:
Step 1: Find <em>x</em>
7x + 46 + 5x + 14 = 180
12x + 60 = 180
12x = 120
x = 10
Step 2: Find the supplementary angle to <em>z</em>
5(10) + 14
50 + 14
64
Step 3: Find <em>z</em>
180 - 64 = 116
