Answer:0.82
Step-by-step explanation:
The first step is to determine the areas of the inner and the bigger circles.
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Considering the inner circle,
diameter = 148.4 cm
Radius = 3 inches
Area = 3.14 × 3² = 28.26 inches²
Considering the bigger circle,
Radius = 7 inches
Area = 3.14 × 7² = 153.86 inches²
The area between the bigger and inner circles is
153.86 - 28.26 = 125.6 inches²
Probability = number of favourable outcome/number of total outcome.
the probability you land inside the bigger circle but outside smaller circle is
125.6/153.86 = 0.82
Answer:
3
Step-by-step explanation:
The magnitude is found by taking the maximum to the minimum
max = 3
minimum = -3
Magnitude = 3--3 = 3+3 =6
The amplitude is 1/2 the magnitude
Amplitude = 1/2 *6 =3
70+95=165
if you typed it into Google it would give the answer too
Answer:
Explained
Step-by-step explanation:
This algorithm does not always give the optimal solution. There is an alternate method as well.
Consider we have to make change for 30 cents, using the least number of coins of denominations 1,10 and 25 cents.According to the given strategy, we first take a 25 cents coin and subtract it from 30 cents. Now, we have to make 5 cents which we can make only from 5 one-cent coins. So, the total number of coins required is 6 according to the given greedy strategy.
But we can simply use 3 ten-cent coins to make change of 30 cents. So, this example proves that the given strategy is not an optimal one.
5+3n=21-n
2n=16
n=8 times in a row
