Answer:
161.92 is the radius
If you want, you can round it to 162 units
For a chad drives 56 miles per hour. you got this by dividing 168 by 3.
for b it takes chad 12 hours and you got this by dividing 672 by 56.
for c, chads car gets 28 miles per gallon you got this by dividing 308 by 11
for d, chads car uses uses 24 gallons to travel 672 miles an you got this by dividing 672 by 28. hope this is right.:)
The probability of rolling a 2 is 1/6. If X is a random variable representing the number of 2s that are obtained after rolling a die 23 times, then X follows a binomial distribution with success probability p = 1/6 across n = 23 trials.
The variance of a binomial distribution with parameters p and n is n p (1 - p), so the standard deviation in this case would be
√(23 • 1/6 • 5/6) ≈ 1.8
Answer:
9
Step-by-step explanation:
1. You would make these to equations equal to each other because there are parellel(they have the same angel)
2. EQUAL these 2 equations together to find r.
3. SOLVING for r
7r - 5 = 6r + 4
r = 9
