Answer:
The answer to the question is;
The probability that there are exactly 4 successes or exactly 4 failures in the 13 rolls is 
.
Step-by-step explanation:
The probability of success = 1/2 =
probability of failure = 1/2
Since we have 4 success we then have 9 failures and the given probability can be solved as ₁₃C₄ × 1/2ⁿ×1/2¹³⁻ⁿ
Therefore we have
₁₃C₄ × 1/2⁴×1/2⁹ = 715/8192
That is the probability that there are exactly 4 successes or exactly 4 failures in the 13 rolls = 715/8192.
Answer:
-3° C < 1°C is the correct option.
Step-by-step explanation:
As we know that:
- The inequality symbol '<' means 'less than'.
- The inequality symbol '>' means 'more than'.
If someone says that something is cooler than the other thing, it indicates that it is lesser than the other based on its temperature.
As the ice cream at −3°C is cooler than ice cream at 1°C, it indicates that temperature -3° C < temperature 1°C.
Therefore, -3° C < 1°C is the correct option.
Both x and y are 79 degrees because vertical angles are congruent.
Answer:
B. (6,-2)
Step-by-step explanation:
The equation of a circle is (x-h)^2+(y-k)^2=r^2
The center of the circle is (h,k)
So, in this problem, h is 6 and k is -2, so the center of this circle is (6,-2).
