Answer:
25m/s
Step-by-step explanation:
distance = 30km = 30× 1000m
time = 20 min = 20 × 60 = 1200sec
we know,
speed = distance/time taken
= 30000/1200
= 25m/s
Part aThe sample size is large enough to use the central limit theorem because it is greater than 30.
Part b.The mean of the sampling distribution is 62000.
The standard error is computed as
Part c.Compute for the corresponding z-score of more than 2700 from the population mean.

Therefore,
There are 100 students. In the 100 students, 79 of them have honors. To find the decimal form for the students who have honors, divide the total amount of students with honors with the total amount of students.

Divide 79 by 100

Your answer is 0.79
Associative property of multiplication means that it doesn't matter where the parentheses are placed because it will still be the same answer.
So your answer would be 1, 4 x (3 x 6) = (4 x 3) x 6
