Answer:

0.3158

Step-by-step explanation:

As we know the column of numbers on the board contains all multiples of 3, that is, 3, 6 9,. , 36., from 3 to 36 we have: 36/3 =12 values.

The probability of winning is the number of divided by the total possible outcomes:

=> P (multiple of 3) = \frac{#favorable outcomes }{# possible outcomes} = \frac{12}{38}  ≈0.3158

If the scale factor for the dilation shown is 3, which is the length of B'C'?
Arturiano [62]

Answer:

15

Step-by-step explanation:

Scale Factor = 3

Using Formula:

Scale Factor = LengthOfDilatedTraingle/LengthOfActualTriangle

Scale Factor =  B'C'/B'C'

B'C' = 3 * 5

B'C' = 15

What are the values of a, b and c in the quadratic equation -2x^2+4x-3=0?
AlladinOne [14]

Answer:

a=-2\\b=4\\c=-3

Step-by-step explanation:

In a quadratic equation in the Standard form

ax^2+bx+c=0

You need to remember that "a", "b" and "c" are the numerical coefficients (Where "a" is the leading coefficient and it cannot be zero: a\neq0).

You can observe that the given quadratic equation is written in the Standard form mentioned before. This is:

-2x^2+4x-3=0

Therefore, you can identify that the values of "a", "b" and "c" are the following:

a=-2\\b=4\\c=-3

The position function of a particle in rectilinear motion is given by s(t) = 2t3 – 21t2 + 60t + 3 for t ≥ 0 with t measured in s
stepladder [879]
When the direction is reversed  velocity = 0 

v = ds/dt =  6t^2 - 42t + 60 = 0

t^2 - 7t + 10 = 0

(t - 5)(t - 2) = 0

t = 2 s  and 5 s   which are the times when the direction is reversed
Position at t = 2 =  2(2)^3 - 21(2)^2 +60(2) + 3 =  55 feet
  at t = 5  position =  28 feet

Acceleration  = dv/dt = 12t - 42

At t = 2  acceleration =  -18 ft s-2
At  t = 5   ...............    = 18 ft s-2
