the correct choice is marked
Step-by-step explanation:
Hello :)
So we are given Miguel bikes 25 km per hour.
Since it is per hour you can take a letter variable (in this case they used t) and multiply it by 25.
Then we are given the fact that he starts at mile 10, we would add this too the 25t because it is where he starts.
So Miguel's system of equations would be; d=25t+10
Now, for gabby we are given the fact that she bikes 30 km per hour. We do the same thing that we did with Miguel we take that number (30) and multiply it by a variable.
then we are given that she starts at 0, so we don't have to include this number.
So Gabby's system of equations would be; d=30t
the answer here would be A
Hope this helps :)
Answer:
μ > 21.21
Test statistic = 1.217
Kindly check explanation for more details
Step-by-step explanation:
The null hypothesis, H0 : μ = 21.21
Alternative hypothesis, H1 : μ > 21.21
The test statistic :
(xbar - μ) ÷ (s/sqrt(n))
(21.212 - 21.21) ÷ (0.01 / √2)
= 1.217
The critical value :
From the t distribution :, one tailed = 2.434
Decision region :
Reject H0 if test statistic > critical value
1.217 < 2.434 ; We fail to reject the null ` ; and conclude that there is not enough evidence to support the claim.
