Answer:
The sample proportion of printers used in small business is:
The 95% confidence interval for the population proportion of printers that are used in small businesses is:
Where:
is the critical value at 0.05 significance level
Therefore, the 95% confidence interval for the population proportion of printers that are used in small businesses is (0.245 , 0.469)
-28 is equal to positive 28
<span>Because there are 20 coins plus four bars = 24 items to choose. You want to choose where to put the four bars, thus C(24,4). There are four bars, not five. Note that four bars divide the 20 coins into five sections. Five bars would divide it into six, but we only have five different kinds of coins to choose from.</span>
Answer:
(f + g)(x) = x² - 3x + 5
Step-by-step explanation:
Here we find the sum of two functions. Combine like terms in f and g, as follows:
(f + g)(x) = x² – 4x – 2 + x + 7, or
(f + g)(x) = x² - 3x + 5
The length of the arc is 4π.
<u>Step-by-step explanation</u>:
Given,
- Diameter = 24 ft
- radius, r = diameter/2
- r = 24/2 = 12 ft
- central angle, ∅ = 60°
Arc length = ∅/360° (2πr)
⇒ 60°/360° (2π
12)
⇒ 24π/6
⇒ 4π
∴ The length of the arc is 4π.
