Answer:
I graphed it and u can find the two solutions :)
Step-by-step explanation:
Answer:
y=x=b=a=s
Step-by-step explanation:
a=s=d=a=s=d=a
If the diameter of the smaller circle is 3.5cm, that means the radius is 1.75cm.The area of the smaller circle is π × 1.75², which is ≈ 9.62112750162.
The diameter of the larger circle is 12.5 cm, so the radius would be half that, which is 6.25cm. The area of the larger circle would be π × 6.25², which is ≈ 122.718463031.
So now that we know the area of the larger circle and the smaller circle, we can find the area of the shaded region by subtracting the area of the smaller circle from the area of the larger circle, which is basically just 122.718463031 - 9.62112750162, which is = 113.097336. The closest answer here is 113.04, hence the answer is 113.04cm².
Answer:
x=2
y= -1
Step-by-step explanation:
Answer:
0.3935 to 4 places of decimals.
Step-by-step explanation:
Use binomial probability tables or an online probability calculator.
Here Prob(a singles success) = 0.08333 ( that is 1/12)
Number of successes = 3 and number of trials = 27.
You want the probability of the variable X being >= x.
