Answer:
153 in²
Step-by-step explanation:
<h3> Area of irregular figure</h3>
Figure I:
length = 12 in
width = 6 in
Area of figure I = 12 * 6
= 72 in²
Figure II:
length = 13 in
width = 5 in
Area of figure II = 13 * 5
= 65 in²
Figure III:
side = 4 in
Area of figure III = 4 * 4
= 16 in²
Area of irregular shape = 72 + 65 + 16
= 153 in²
Answer:
1. subtract
2. quotient
3. multiply
4. times
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You need to apply the following formula:
2. You have that the distance is and the time is . Therefore, you only have to substitute values into the formula. So, you obtain:
The answer is:
The solution for this problem is:
The x-bar or the mean is = 150Confidence level is 80%sample size is 36
E = t*s/sqrt(n)= 1.3062*40/sqrt(36)=1.3062 * 6.66667= 8.708
An 80% Confidence Interval is: 150-8.708 < u < 150+8.708Or141.3 < u < 158.7 is the confidence interval
