Answer:
Area = 152ft²
Step-by-step explanation:
Simpifly:
A = 13(13-6) + 9(13-6)
A = 13(7) + 9(7)
A = 22(7)
A = 22(7)
A = 20(7)+2(7)
A = 140 + 14
A = 152

Answer with explanation:</h2>
Let be the population mean.
Null hypothesis :
Alternative hypothesis :
Since the alternative hypothesis is left tailed, so the test is a left-tailed test.
Sample size : n=5 <30 , so we use t-test.
Test statistic:
Critical t-value for t=
Since, the absolute value of t (1.79) is less than the critical t-value , so we fail to reject the null hypothesis.
Hence, we have sufficient evidence to support the company's claim.
Answer:
92.5km
Step-by-step explanation:
By cross multiplication you will get 2x=7.4x25.(cross multiply map scale = 2cm and 7.4 put them under each other and for the actual distance it's 25 km and X cross multiply and that's how u get 2x=7.4*25) now u will multiply 7.4*25 u will get 185 and then divide by 2 on each side so the x is left alone (2x/2=185/2) which will give you x=92.5km.
