Answer:

x = 28/3

Step-by-step explanation:

We can solve this problem by using similar triangles:

Both of these triangles have a 90 degree angle and they share angle A, meaning that they are similar by AA similarity.

Now we can set up ratios and solve:

13/7 = (x+8)/x

multiply both sides by x:

13x/7 = x+8

Multiply both sides by 7:

13x = 7x + 56

move the 7x over and divide by 6:

6x = 56

x = 28/3

Here are summary statistics for randomly selected weights of newborn girls: n=185,

Anna11 [10]

Answer:

The confidence interval for the population mean μ is $32.487$

Step-by-step explanation:

Given :

Number of weights of newborn girls n=185.

Mean $\bar{x}=31.4$ hg

Standard deviation s=7.5 hg

Use a 95% confidence level i.e. cl=0.95

To find : What is the confidence interval for the population mean μ?

Solution :

Using t-distribution,

The degree of freedom $DF=n-1=185-1=184$

$\alpha=\frac{1-0.95}{2}$

$\alpha=0.025$

The t critical value is t=1.973.

The confidence interval build is

$CI=\bar{x}\pm(t\cdot \frac{s}{\sqrt{n}})$

Substitute the values,

$CI=31.4\pm(1.973\cdot \frac{7.5}{\sqrt{185}})$

$CI=31.4\pm(1.973\cdot 0.5514)$

$CI=31.4\pm(1.087)$

$31.4+1.087$

$32.487$

Therefore, the confidence interval for the population mean μ is $32.487$
