Mr. Clark claims that he has a coin that is weighted so that the probability of heads is 40%. To test this, his students flip th

e coin 200 times and calculate the relative frequency of heads and tails.
Outcome Heads Tails
Relative frequency 0.38 0.62


Select from the drop-down menus to correctly complete each statement.

The relative frequency of heads is

40%.

Mr. Clark's claim about the theoretical probability is likely to be

.

This means that the theoretical probability of tails is most likely
for this coin.

While I'm unsure what the word choices were, his claim is likely to be true. 

Since he claims the probability of heads is 40%, that should be what we see in an experiment.  0.38 is very close to 0.40, or 40%, so this is true.  Therefore his claim is likely to be true, and the probability of tails should be about 60%.

Which two values of x are roots of the polynomial below?
Julli [10]

Answer:

B. and C.

Step-by-step explanation:

1. Set the polynomial equal to zero:

x² + 5x + 7 = 0

2. Plug the given values of a, b, and c into the quadratic formula:

x=\frac{-5+-\sqrt{5^{2}-4(1)(7) } }{2(1)}

3. Solve the square root:

x=\frac{-5+-\sqrt{25-4(1)(7)} }{2(1)}

x=\frac{-5+-\sqrt{25-28} }{2(1)}

x=\frac{-5+-\sqrt{-3} }{2(1)}

4. Simplify the rest:

x=\frac{-5+-\sqrt{-3} }{2}

5. Separate the solutions:

x=\frac{-5+\sqrt{-3} }{2}  , x=\frac{-5-\sqrt{-3} }{2}

Thus, options B and C are the answers.

hope this helps!
