Answer:

$x^{15}$

Step-by-step explanation:

Distribute the ^3 on top

(27 $x^{6}$ $y^{-9}$ )

distribute the ^ -9 on bottom, only to what is in the parenthesis

(27 $x^{-9}$ $y^{-9}$ )

the 27's cross out, the $y^{-9}$ 's cross out

$x^{6}$ / $x^{-9}$ is left

move the $x^{-9}$ to the top of fraction to change its sign

$x^{6}$ · $x^{9}$ = $x^{15}$

Among 21- to 25-year-olds, 29% say they have driven while under the influence of alcohol. Suppose that three 21- to 25-year-olds

Sophie [7]

Answer:

P(3) = 0.0244

P(3) = 2.44%

the probability that all three selected have driven while under the influence of alcohol is 2.44% or 0.0244

Step-by-step explanation:

Given;

The probability that they have driven while under the influence of alcohol is;

P = 29% = 0.29

the probability that all three selected have driven while under the influence of alcohol is;

P(3) = P × P × P

P(3) = 0.29 × 0.29 × 0.29

P(3) = 0.024389

P(3) = 0.0244

P(3) = 2.44%

the probability that all three selected have driven while under the influence of alcohol is 2.44% or 0.0244

Plz help i need helppppppp

Goshia [24]

Answer:

1) 36

b) 5

c) 3.0

Step-by-step explanation:

1) The recursive formula that defines the given sequence is

$a_1=12 \\ a_n=a_{n-1}+4.$

That means we keep adding 4 to the subsequent terms:

The sequence will be:

12,16,20,24,28,32,36,...

Therefore the seventh term is 36.

2) The sequence is recursively defined by;

$a_1=20\\ a_n=a_{n-1} - 5$

This means, we have to keep subtracting 5 from the subsequent terms.

The sequence will be;

20,15,10,5,...

Therefore the fourth term is 5

3) The sequence is recursively defined by:

f(n+1)=f(n)+0.5

where f(1)=-1.5

This means that, the subsequent terms can be found by adding 0.5 to the previous terms.

The sequence will be:

-1.5,-1.0,-0.5,0,0.5,1,1.5,2.0,2.5,3.0,....

Therefore f(10)=3.0
