Answer:

  • D.  15.3%

Step-by-step explanation:

<u>Total number of outcomes:</u>

  • 2¹⁵ =  32768

<u>Number of combinations of getting 6 heads:</u>

  • 15C6 = 15!/6!(15-6)! = 5005

<u>Required probability is:</u>

  • P(6 heads out of 15 flips) = 5005/32768 = 0.1527... ≈ 15.3%

Correct choice is D

Answer:

option D

Step-by-step explanation:

Total sample space

                               =  2^{15}

Number of ways 6 heads can emerge in 15 flips

                                                                          = 15C_6  

Probability:

               =\frac{15C_6}{2^{15}} = 0.1527

Probability to the nearest percent : 15.3%

the third side of an isosceles triangle is 8 inches shorter than the other two sides the perimeter of the triangle is 70 inches
dezoksy [38]
Isosceles triangle has 2 sides that are the same length. So what you have is three sides that measure: x, x, and (x-8). 70 = x + x + (x-8).
70 = x + x + x - 8
78 = 3x
x = 26.
and 26 - 8 = 18.
So two of your sides are 26 inches and the last side is 18 inches.

victus00 [196]

Answer:

The answer is

\huge y - 8 =  4(x + 9) \\

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

From the question we have the final answer as

y - 8 =   4(x + 9)

Hope this helps you
