Answer:
Your measurements; Area = 216.108 cm²
Another student's measurements; Area = 216.9404 cm²
- Difference in area could be as a result of human error or perhaps that they made use of different measuring tools.
Step-by-step explanation:
For Your measurements;
Length of rectangle = 20.70 cm
Width of rectangle = 10.44 cm
Area of rectangle is given by; A = length × width = 20.7 × 10.44 = 216.108 cm²
For Another student's measurements;
Length of rectangle = 20.74 cm
Width of rectangle = 10.46 cm
Area = 20.74 × 10.46
Area = 216.9404 cm²
The areas they both obtained are not of equal values and this could be as a result of human error or perhaps that they used different measuring tools.
Answer:
2 units
Step-by-step explanation:
because the only whole number factor pair to 10 is 2x5 and luckily, it turned out that 5-3=2, so there are no decimals or fractions. Yay!
Answer:
0.632 ; 0.233
Step-by-step explanation:
Given that :
Conversation average λ = 1/5 = 0.2
Using the poisson distribution function :
P(x) = 1 - e^(-λ/x)
p(< 5) = 1 - e^-(1/5 * 5)
P(<5) = 1 - e^-1
P(< 5) = 1 - 0.3678794
= 0.6321205
= 0.632
B.) between 5 and 10 minutes
5 < x < 10
P(x< 5) - p(x< 10)
P(< 5) = 1 - 0.3678794 = 0.6321205
P(< 10) = 1 - (e^-1/5 * 10)
P(< 10) = 1 - e^-2 = 1 - 0.1353352 = 0.8646648
P(< 10) - P(<5)
0.8646648 - 0.6321205
=0.2325443
= 0.233
Answer: The cost per game is $5.5
Step-by-step explanation:
Zhang Lei spent $20.00 during his last outing at the bowling alley. There is a one time shoe rental fee of $3.50. He spent the rest of the money on bowling a number of games.
This means that amount paid for x number of games = 20 - 3.5 = $16.5
If it took Zhang Lei 45 minutes to bowl each game and he spent 2 hours and 15 minutes bowling, total time spent in minutes is 120+ 15 = 135 minutes. Therefore, the number of games is played is 135/45 = 3
If the total number of games played cost 16.5, therefore, the cost per game will be 16.5/3 = $5.5
Answer:
4
Step-by-step explanation:
First, you would have to prime factorize both of the numbers. The prime factorization of 24 is 24 = 2*2*3*3, and the prime factorization of 32 is 32 = 2*2*2*2*2 or 2^5. After that, you would find what is most common:
24 = 2*2*3*3
32 = 2*2*2*2*2
What is common is that there is two 2's in each equation. 2*2 is 4, so the answer is 4.
Hope this helps! <3
