Step-by-step explanation:
Given
The perimeter of one equilateral triangle is P
The lengths of the equilateral triangle are equal
Suppose x is the length of each side
i.e.
The given dimensions of 9.5, 6, 7, and 6.5 cm gives the following
perimeter and area of the trapezium.
- Perimeter: <u>29 cm</u>
- Area: <u>49.5 cm²</u>
The perimeter of a trapezoid is given as follows;
Perimeter = The sum of the lengths of the sides
Which gives;
Perimeter = 6 + 7 + 6.5 + 9.5 = 29
The perimeter of the trapezoid =<u> 29 cm</u>
- Perimeter: 29 cm
The area of the trapezoid is given as follows;
Which gives;
The area of the trapezoid = 49.5 cm²
- Area:<u> 49.5 cm²</u>

Answer:
The value of 725 Mexican pesos is equals to 37.66 US dollars
Step-by-step explanation:
Given as :
The value of 1 US dollar equals to 19.25 Mexican pesos
The total amount of Mexican pesos = 725
Now,
∵ 19.25 Mexican pesos equals to 1 US dollars
∴ 725 Mexican pesos equals to = 37.66 US dollars
Hence The value of 725 Mexican pesos is equals to 37.66 US dollars Answer
<h2><u>Answer with explanation</u>:</h2>
Let be the population mean.
As per given , we have
Since the alternative hypothesis is right-tailed , so the test is a right-tailed test.
Also, population standard deviation is given , so we perform one-tailed z-test.
Test statistic :
, where = Population mean
= Population standard deviation
n= sample size
= Sample mean
For n= 18 , ,
,
, we have
P-value (for right tailed test): P(z>2.12) = 1-P(z≤ 2.12) [∵ P(Z>z)=1-P(Z≤z)]\
=1- 0.0340=0.9660
Decision : Since P-value(0.9660) > Significance level (0.01), it means we are failed to reject the null hypothesis.
[We reject null hypothesis if p-value is larger than the significance level . ]
Conclusion : We do not have sufficient evidence to show that the goal is not being met at α = .01 .
