Answer:

x = 6

Step-by-step explanation:

Since BD is an angle bisector then the following ratios are equal

$\frac{BC}{BA}$ = $\frac{CD}{AD}$ , that is

$\frac{8}{x}$ = $\frac{4}{3}$ ( cross- multiply )

4x = 24 ( divide both sides by 4 )

x = 6

Answer:

5,562 x $10^{-6}$

Step-by-step explanation:

Firts, we need to find the maximum recommended amount of bluefish per month. Since the FDA recommends 3 servings of 6.00 oz each, the maximum amount would be:

the maximum amount of bluefish per month = $3 * 6.00 oz = 18.00 oz$

Since bluefish contains 0.309 ppm of mercury per 1x $10^{6}$ oz of fish, then:

0.309 oz mercury --------> 1x $10^{6}$ oz of fish

How many ( $y$ ) --------> 18.00 oz of fish

$y = \frac{18.00 oz of fish * 0.309 oz of mercury}{1 x 10^{6} oz of fish } = 0.000005562 = 5.562 x 10^{-6}$ oz mercury

Answer:

0.0623 ± ( 2.056 )( 0.0224 ) can be used to compute a 95% confidence interval for the slope of the population regression line of y on x

Step-by-step explanation:

Given the data in the question;

sample size n = 28

slope of the least squares regression line of y on x or sample estimate = 0.0623

standard error = 0.0224

95% confidence interval

level of significance ∝ = 1 - 95% = 1 - 0.95 = 0.05

degree of freedom df = n - 2 = 28 - 2 = 26

∴ the equation will be;

⇒ sample estimate ± ( t-test) ( standard error )

⇒ sample estimate ± ( $t_{\alpha /2, df$ ) ( standard error )

⇒ sample estimate ± ( $t_{0.05 /2, 26$ ) ( standard error )

⇒ sample estimate ± ( $t_{0.025, 26$ ) ( standard error )

{ from t table; ( $t_{0.025, 26$ ) = 2.055529 = 2.056

so we substitute

⇒ 0.0623 ± ( 2.056 )( 0.0224 )

Therefore, 0.0623 ± ( 2.056 )( 0.0224 ) can be used to compute a 95% confidence interval for the slope of the population regression line of y on x
