Answer:
0.4
Step-by-step explanation:
Given:
Dana found that 8 students earned an A, 6 students earned a B, 4 students earned a C, and 2 students earned a D on the last science test.
To find:
the experimental probability that the student would have earned an A in the test
Solution:
Probability refers to the chances of occurrence of some event.
Number of students who earned an A in the test = 8
Total number of students = 8 + 6 + 4 + 2 = 20
The experimental probability that the student would have earned an A in the test = Number of students who earned an A in the test / Total number of students = 
Answer:
270°
Step-by-step explanation:
Important: Please express fractions properly: use the " / " symbol to represent division. Your question should read:
"<span>A Mallard duck flies 5/6 of a mile in 1/60 of a hour. Find the rate (speed) at which it flies."
To do this, divide the distance flown by the elapsed time:
5
5/6 mile -----
----------------- = -------6------------- miles / hr
1/60 hour </span>
1
-----
60
to divide 5/6 by 1/60, write 5/6 and multiply that by the reciprocal of 1/60.
In other words, write 5/6, invert (1/60) and then multiply.
This comes out to (5)(60)
---------- mph
(6)(1)
Do not multiply here. Instead, reduce 60/6 to 10/1.
Can you now write out the final answer, in mph? (miles per hour)
Answer:
Volume of Beads = 84 mm³
Step-by-step explanation:
Given:
Side of base = 6 mm
Height = 7 mm
Find:
Volume of Beads
Computation:
Volume of Beads = Volume of a square pyramid
Volume of Beads = [1/3][Area of base][h]
Volume of Beads = [1/3][6 x 6][7]
Volume of Beads = 84 mm³
