4(4-w)=3(2w+2)<br>find w​
Travka [436]

Answer:

1

Step-by-step explanation:

4(4-w) = 3(2w+2)

Use distributive property:

16 - 4w = 6w + 6

    +4w  +4w

------------------------

     16 = 10w + 6

    -6              -6

-------------------------

        10 = 10w

        ----    -----

        10      10

         1 = w

Hope this helped.

PLEASE HELP ASAP NO LINKS

<u><em>function </em></u>: p(x) = 65 + 25(x)

for 3 sells

  • p(3) = 65 + 25(3)
  • p(3) = 140

for 10 sells

  • p(10) = 65 + 25(10)
  • p(10) = 315

So,

140 ≤ p(x) ≤ 315

In the United States, the mean age of men when they marry for the first time follows the normal distribution with a mean of 24.6
Sedbober [7]

Answer:

z= \frac{25-24.6}{\frac{2.8}{\sqrt{66}}}=1.16

So we want to find this probability:

P(z

And using the normal standard distirbution or excel we got:

P(z

Step-by-step explanation:

Let X the random variable that represent the age of men married of a population, and for this case we know the distribution for X is given by:

X \sim N(24.6,2.8)  

Where \mu=24.6 and \sigma=2.8

We are interested on this probability

P(\bar X

The sample size is n =66. We can use the z score to solve this problem:

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

If we find the z score for 25 we got:

z= \frac{25-24.6}{\frac{2.8}{\sqrt{66}}}=1.16

So we want to find this probability:

P(z

And using the normal standard distirbution or excel we got:

P(z
