Answer: 9(3 + 2r)

<u>Step-by-step explanation:</u>

      27                     18r

       ∧                       ∧

    <u>3</u>  9                    <u>2</u>  9r

         ∧                         ∧

        <u>3</u>  <u>3</u>                     <u>3</u> <u>3r</u>

27: 3 * 3 * 3

18r: 2 * 3 * 3 * r

Common Factors are 3 * 3 = 9

27: 9 * <u>3</u>

18: 9 * <u>2r</u>

27 + 18r  =  9(3 + 2r)

In the United States, the mean and standard deviation of adult men's heights are 70 inches (5 feet 10 inches) and 4 inches, resp
Artyom0805 [142]

Answer:

P(X>72)=P(\frac{X-\mu}{\sigma}>\frac{72-\mu}{\sigma})=P(Z>\frac{72-70}{4})=P(z>0.5)

And we can find this probability using the complement rule and the normal standard table:

P(z>0.5)=1-P(z

And the best solution would be:

c. 0.3085

Step-by-step explanation:

For this case we can convert all the values to inches in order to standardize the solution:

5ft * \frac{12 in}{1ft}= 60 in

6ft * \frac{12 in}{1ft}= 72 in

Let X the random variable that represent the heights of US mens, and for this case we know the distribution for X is given by:

X \sim N(70,4)  

Where \mu=70 and \sigma=4

We are interested on this probability

P(X>72)

We can use the z score formula given by:

z=\frac{x-\mu}{\sigma}

Using this formula we got:

P(X>72)=P(\frac{X-\mu}{\sigma}>\frac{72-\mu}{\sigma})=P(Z>\frac{72-70}{4})=P(z>0.5)

And we can find this probability using the complement rule and the normal standard table:

P(z>0.5)=1-P(z

And the best solution would be:

c. 0.3085

How to solve log5 x/2 = 5? i got it to 2^5=x/2 but i have NO CLUE how to solve from there?
Lerok [7]
Well
log_a(b)=c translates to a^c=b
so
log5(x/2)=5 means 5^5=x/2, so 3125=x/2, so 6250=x
