On the map, a distance of 20 miles are represented by 1 inch .
So distance of 1 mile is represented by
And therefore, distance of 135 miles are represented by
Answer:
The answer is D 7sqrt2
This is due to the fact that i just learned this and the hypotenuse is always the hypotenuse is the leg sqrt of 2 so it would be D
Answer:
3.06
Step-by-step explanation:
The correct answer is - 3.06
Reason -
For sample A :
mean, = 8.05
Standard deviation, = 1.36
Size, = 50
For sample B :
mean, = 7.26
Standard deviation, = 1.06
Size, = 38
Now,
- = 8.05 - 7.26 = 0.79
Standard deviation error, SE = √(²/ + ²/) = 0.2580
Now,
Z-statistic = ( - )/ SE
= 0.79/0.2580
= 3.06
⇒Z-statistic = 3.06
Here is the solution for the given problem above.
The formula for getting the distance is distance = rate x time.
Given that the rate is 0.12miles/minute and the time is 9 minutes, we simply substitute the values to the formula.
So distance = 0.12miles/minute x 9 minutes and we get 1.08 miles. So the distance that she can walk for 9 minutes is 1.08 miles. Hope this answers the question.
