Answer:
0.8937
Step-by-step explanation:
This is a case of binomial probability with n = 64, p = 0.10 and x = 3. This means that the probability of a cancellation is 10%. Here, we can find the probability that more than 3 cancellations or no shows will occur by finding binompdf(64,0.10, 0) + binompdf(64,0.10, 1) + binompdf(64,0.10, 2) + binompdf(64,0.10, 3) and then subtracting this sum from 1.000.
We get: 0.0012 + 0.0084 + 0.0293 + 0.0674 = sum = 0.1063
Then the desired probability is 1.0000 - 0.1063 = 0.8937

Answer:
Part A: option C. 135.2°F
Part B: 40 min
Step-by-step explanation:
<em>Part A:</em><em> What is the temperature in degrees Fahrenheit of the soup after 25 minutes?</em>
<u>1. Set an equation</u>:
- Temperature = Initial temperature - decrease in temperature
- decrease in temperature = rate of decrease × time
- Variables:
temperature: T
initial temperature: To = 192.7°F
decrease rate: 2.3°F / min
time = t
- Equation: T = 192.7°F - 2.3(°F/min) × t
2.<u> Substitute t = 25 min</u>
- T = 192.7°F - 2.3 (°F/min) × 25 min = 135.2 °F
Part B. <em>How many minutes will it take for the soup to cool to 100.7°F?</em>
2.<u> Solve the equation for t</u>
- T = 192.7°F - 2.3(°F/min) × t ⇒ t = (192.7 °F - T) / (2.3 °F/min)
3. <u>Substitute T = 100.7°F</u>
- t = (192.7°F - 100.7°F) / (2.3 °F/min) = 40 min
Answer: The combined area of the shaded triangles in Figure one is equal to the combined area of the shadead triangles in figure 2. The area of the unshaded square in Figure 1 can be represented by c^2. The combined area of the two unshaded squares in Figure 2 can be represented by a^2+b^2. The areas of the squares in Figure 1 and Figure 2 who that a^2+b^2=c^2.
