Answer:
A. 0.020
Step-by-step explanation:
we calculate the standard error of the sample mean with the formula,
,
with E= standard error of the sample mean
s= standard deviation
n= sample
So,
s= 0.2
n= 100

Complete question :
Kiran and clare live 24 mile away from each other along a rail trail. One Saturday the two friends started walking toward each other along a trail at 8:00 am with a plan to have a picnic when they meet. Kiran says "If I walk 3 miles per hour toward you, and you walk 3.4 miles per hour toward me, it's the same as if you stay put and I jog 6.4 miles per hour."What do you think Kiran means by this, Is he correct?
Answer:
Kindly check explanation
Step-by-step explanation:
A walks 3 miles per hour
B walks 3.4 miles per hour
Total distance = 24 miles
Average speed of both A and B = (3 + 3.4) = 6.4 miles
Time = distance / speed
If A jogs at 6.4 miles per hour while B stays put
Time = 24 miles / 6.4 miles per hour
Time = 3.75 hours = 3 hours 45 minutes
In terms of when both A and B will meet ; they'll both meet after 3 hours 45 minutes either they walk towards each other at 3mph and 3.4mph respectively or one takes their combined speed to jog towards the other who is staying put.
However, the meeting point will be different and distance covered by each person won't be the same.
As for the time taken to cover 24 miles, it will be 3 hours 45 minutes in both cases.
177 divided by 39 is 4.5 so either 4 or 5 baskets is needed. I think 4.5 though or 5 because you’d need more space rather than not enough if that makes sense
Answer:
x=5
Step-by-step explanation:
I first subtracted 88 from 180 because we know that 180 is the total degree of the three angles in a trangle. I got 92, then divided that by 2 since there are two angles that are unknown. I got 46, which I can then use to form the equation (9x+1)=46. I subtracted 1 from both sides to get rid of the 1 (since we're finding what x equals to), I then got 9x=45. After that, I divided 9 from both sides and got the answer x=5.
Hope this helped you : )
