Step-by-step explanation:
Answer:
(A)20%, 20%, 20%, 20%, 20%
Step-by-step explanation:
We are told that 20% of the M&M's produced by the Mars Corporation are Orange in color. If 5 students take a random sample of 50 M&M's, the most plausible percentage of orange candies that will be obtained is:
20%, 20%, 20%, 20%, 20%
This is as a result of the fact that in research experiments, a sample is a representation of the whole. Any result which holds for a random sample should hold for the total population and vice versa.
Answer:
40
Step-by-step explanation:
Answer:
9 3/4
Step-by-step explanation:
Pounds of bananas=2 7/8
=23/8
Pounds of apple=3 1/2
=7/2
2 bags of oranges=2 3/4 each
11/4 each.
Total pounds of oranges=2(11/4)
=22/4
Total pounds of fruits Marisol bought from the market=pounds of bananas+pounds of apples+pounds of oranges
=28/8+7/2+22/8
Find the L.C.M and add them
The L.C.M=8
Total pounds of fruits =28+28+22/8
=78/8
=9 6/8
Equivalent to
9 3/4
Complete the square to rewrite the quadratic:
2 <em>x</em>² + 3 <em>x</em> + 5 = 2 (<em>x</em>² + 3/2 <em>x</em>) + 5
... = 2 (<em>x</em>² + 3/2 <em>x</em> + 9/16 - 9/16) + 5
... = 2 (<em>x</em>² + 3/2 <em>x</em> + (3/4)²) + 5 - 9/8
... = 2 (<em>x</em> + 3/4)² + 31/8
Any real number squared becomes non-negative, so the quadratic expression has a minimum value of 31/8, which is greater than 0, and so there are no (real) <em>x</em> for which <em>y</em> = 0.
