Answer: The probability is 1/8

Explanation:

Probability is a ratio of the number of relevant outcomes and total number of possible outcomes.

We are flipping the coin three times.

The number of relevant outcomes is 1 (one triple {Head, Head, Tail})

The number of all possible outcomes is the product of 2 possibilities (Head or Tail) on first toss, times another 2 on second, times another 2 on third, so 2^3 = 8.

The probability P = 1/8

Step-by-step explanation:

$log_{3}( \frac{4x}{{3}^{2} } ) = 2$

${3}^{2} = \frac{4x}{ {3 }^{2} }$

9=4x/9

81=4×

x=81/4

adding logs means elements are multiplied, subtracting means divide. number in front of log is raised to power

base of log is raised to power of element after =

element in log is then equal to log base raised to power

solve resulting equation

A concert cleanup crew has 6 workers and one cleanup kit.

myrzilka [38]

Answer:

Option (D)

Step-by-step explanation:

At every 6 crew workers number of clean up kits required = 1

Therefore, for 1 crew worker number of kits required = $\frac{1}{6}$

And number of kits required for w workers = $\frac{w}{6}$ = w ÷ 6

If w = 54

Number of kits required = $\frac{54}{6}=9$

If w = 60

Number of kits required = $\frac{60}{6}=10$

If w = 66

Number of kits required = $\frac{66}{6}=11$

Therefore, table given in Option (D) is the correct table.
