Solving for x thank youu

Svetach [21]

Answer:

sqrt (90)

Step-by-step explanation:

(13+5) is to z as z is to 5

(13+5) / z = z/5

18/z = z/5

90 = z^2

z = sqrt (90)

A random sample of 16 men have a mean height of 67.5 inches and a standard deviation of 2.22.2 inches. Construct a 99% confiden

saw5 [17]

Answer: $\approx1.49$

Step-by-step explanation:

We know that the confidence interval for population standard deviation is given by :-

$\sqrt{\dfrac{(n-1)s^2}{\chi^2_{\alpha/2}}}$

, where n= sample size

s = sample standard deviation.

$\chi^2_{\alpha/2}$ and $\chi^2_{1-\alpha/2}$ = Chi-square critical value for degree of freedom (n-1) and significance level ( $\alpha$ ).

Given : $\alpha=1-0.99=0.01$

n= 16

Critical ch-square values for degree of freedom 15 and $\alpha=0.01$ will be :

$\chi_{\alpha/2}=\chi_{0.005}=32.80132$

$\chi_{1-\alpha/2}=\chi_{0.995}=4.6009$

Then , the required 99% confidence interval for the population standard deviation will be :

$\sqrt{\dfrac{(15)(2.2)^2}{32.80132}}$

$\sqrt{2.21332556129}$

$1.48772496157$

$\approx1.49$

Hence, the a 99% confidence interval for the population standard deviation :

mihalych1998 [28]

Answer:

$\frac{1}{8}$

Step-by-step explanation:

The total amount of cards is 8, and the stack have 4 even numbers, so the probability is

4/8 Simplify it and

1/2

Now, there are just 6 cars bigger than 6, so:

2/8. Simplify it

1/4

Now you have to multiply the two values:

1/2×1/4 = 1/8
