How can I solve for y and what is the answer

Aleks [24]

Answer:

y = 38

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Consider the angles in the large outer triangle, then

x + 46 + 78 = 180

x + 124 = 180 ( subtract 124 from both sides )

x = 56

Consider the 3 angles in the smaller inner triangle, then

y + x + 86 = 180 , that is

y + 56 + 86 = 180

y + 142 = 180 ( subtract 142 from both sides )

y = 38

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:

$P(z$
