Tossing a die will have 6 possible outcomes. Those are having sides that are number 1 to 6. The sample space of tossing 3 dice is equal to 6³ which is equal to 216. Now for the calculation of probabilities,
P(two 5s) = (1 x 1 x 5)/216
As we have to have the 5 in the die for two times, then for the 1 time, we can have all other numbers except 5. The answer is 5/216.
P(three 5s) = (1 x 1 x 1)/216 = 1/216
P(one 5 or two 5s) = (1 x 5 x 5)/216 + (1 x 1 x 5)/216 = 5/36
The answer would be B: Dividing the number by 1000
Every time you move the decimal, add a zero. Since the decimal is moved three times, there are three zeroes. When you move left, the number is getting smaller so it is division.
Step-by-step explanation:
<h2>#a</h2>
p : c
4 : 3 = x : 36
3x = 4 × 36
3x = 144
x = 48
<h2>
#b</h2>
p + c = 70
c = 3/7 × 70
c = 3 × 10
c = 30
Answer:
I will pick letter c. 8,12,5,7,4
A circle's size and shape is fully defined by its radius. Given two circles with radii r and r', the diameters are d=2r and d'=2r' and they are in the ratio
<span>d'/d = (2r')/(2r) = r'/r. </span>
<span>The diameter ratio is the same as the radius ratio. Similarly, the circumferences c=πd and c' = πd' are in the ratio </span>
<span>c'/c = (πd')/(πd) = d'/d = r'/r </span>
<span>The circumference ratio is the same as the diameter ratio and the radius ratio. All of the key linear dimensions are in the same proportion. </span>
<span>You might point out that the same thing happens with a square, where the size and shape are also completely determined by a single measurement, the length s of a side, with the diagonal and perimeter (corresponding to diameter and circumference) being d = √2 s and p = 4s. </span>
<span>Maybe you can lead at least some of the students to generalize to other regular polygons. Some of them (like the equilateral triangle and regular hexagon) can be demonstrated like the square and circle above with formulas from geometry. The general case needs trig ratios to state the formulas relating side length to the radius and apothem of the polygon.</span>
