For a certain population of men, 8 percent carry a certain genetic trait. For a certain population of women, 0.5 percent carry t

Lena [83]

Answer:

(D) 200 men and 2,000 women

Step-by-step explanation:

To have an approximately normal distribution for the difference between proportions, we have to have sample sizes that are big enough to satisfy this conditions:

$np>10\\\\n(1-p)>10$

For men, we have p=0.08, so we have:

$n*0.08>10\Rightarrow n>125\\\\n(1-0.08)=n*0.92>10 \Rightarrow n>11$

The sample size for men has to be at least 125 individuals.

For women, we have p=0.005:

$n*0.005>10\Rightarrow n>2000\\\\n(1-0.005)=n*0.995>10 \Rightarrow n>11$

The sample size for women has to be at least 2000 individuals.

The option that satisfy the requirements for men and women is Option D, as the others don't have enough sample size for women.

What is the value of log 27^9?

KengaRu [80]

Answer: The answer is $\dfrac{2}{3}.$

Step-by-step explanation: We are given to find the value of $\log_{27}9.$

Here, we will be using the following properties of logarithm.

$(i)~\log a^b=b\log a,\\\\(ii)~\log_ba=\dfrac{\log a}{\log b}.$

So, we will be solving the given problem using these two as follows.

$\log_{27}9=\dfrac{\log9}{\log27}=\dfrac{\log 3^2}{\log 3^3}=\dfrac{2\log 3}{3\log 3}=\dfrac{2}{3}.$

Thus, the required value is $\dfrac{2}{3}.$

Solve by substitution (show steps) -3x-4y=10 -6x+y=-16

natali 33 [55]

1) -3x-4y=10 ==> - 3x = 10+4y ===> 3x= -10-4y==> x=(-10-4y)/3
Now replace x by its value in 2)

2) -6x+y=-16 ==> - 6[( - 10- 4y)/3] + y = -16 ==> -2[(-10-4y] +y =- 16
+20+8y+y =- 16==> 9y = - 16 - 20 ==> 9y = -36 & y = - 4.

Now replace y by (- 4) in any of the 2 equations & you will find x = 2
