The probabilities of knocking down zero, one, and two pins are 0.175, 0.189, and 0.264, respectively.  The total probability of knocking down at most two is thus 0.175+0.189+0.264=0.628, or 62.8%.

Holding a ruler upright at arm’s distance (24 in.), Ronnie aligned the bottom of the ruler with a mark on the utility pole that
atroni [7]

Answer:

10 feet

Step-by-step explanation:

Drawing obviously not to scale but... Red segment is the ruler, at least the part between 5 and 6 inches, 1 inch long. Brown segment is the pole, ground to the top. Leftmost point is the eye, green line is the horizontal. The triangles are similar (AAA, the vertical lines are parallel), the ratio of the side is the same as the ratio of the heights. The height of the larger triangle (measured across the green line is

40 yd \times 3\frac{ft}{yd} \times 12\frac{in}{ft}= 1440''.

Ratio of the height is then 1440\div24 = 60.

At this point the height of the pole is 60 times the length of the measure on the ruler, or 60 inches, that is 5 feet. Add the 5 feet the pole was starting from, it's 10 feet.

The permeters of the triangles shown are equal. Find the side lengths of each triangle
Zielflug [23.3K]

Answer:

AB = 51

BC = 50

AC = 42

PQ = 42

QR = 42

PR = 59

Step-by-step explanation:

Perimeter of ∆ ABC = Perimeter of ∆ PQR

3x + 9 + 3x + 8 + 3x = 3x + 3x + 4x + 3

9x + 17 = 10x + 3

17 - 3 = 10x - 9x

14 = x

.: x = 14

AB = 3x +9 = 3×14+9 = 42+9 = 51

BC = 3x +8 = 3×14+8 = 42+8 = 50

AC = 3x = 3×14 = 42

PQ = 3x = 3×14 = 42

QR = 3x = 3×14 = 42

PR = 4x +3 = 4×14+3 = 56+3 = 59
