1 answer:

6 0

X^2+92 is the simplest form first solve the second parentheses. 10^2+2=102 then add -10. 102+-10 is the same as 102-10=92 plug back in x^2+92.

koban [17]

Answer:

98% of confidence intervals for the Population proportion of people who captured after appearing on the 10 most wanted list

(0.3583 , 0.4579)

Step-by-step explanation:

Explanation:-

Given sample size 'n' = 517

Given data Suppose a sample of 517 suspected criminals is drawn. Of these people, 211 were captured.

'x' =211

The sample proportion

$p^{-} = \frac{x}{n} = \frac{211}{517} =0.4081$

$q^{-} = 1-p^{-} = 1- 0.4081 = 0.5919$

98% of confidence intervals for the Population proportion of people who captured after appearing on the 10 most wanted list

$(p^{-} - Z_{\frac{\alpha }{2} } \sqrt{\frac{p^{-} (1-p^{-} )}{n} } , p^{-} + Z_{\frac{\alpha }{2} } \sqrt{\frac{p^{-} (1-p^{-} }{n} } )$

$(0.4081 - 2.326 \sqrt{\frac{0.4081 (0.5919 )}{517} } , 0.4081+ 2.326\sqrt{\frac{0.4081(0.5919 }{517} } )$

(0.4081-0.0498 , 0.4081 +0.0498)

(0.3583 , 0.4579)

Conclusion:-

98% of confidence intervals for the Population proportion of people who captured after appearing on the 10 most wanted list

(0.3583 , 0.4579)

The hypotnuse of a 45-45-90 triangle has a length of 10 units whats the length of one of its legs

mamaluj [8]

Answer:

5√2 units ≈ 7.07 units

Step-by-step explanation:

The ratio of leg to hypotenuse in an isosceles right triangle is ...

leg/hypotenuse = 1/√2

Multiplying by the length of the hypotenuse, we have ...

leg = hypotenuse/√2 = 10/√2

leg = 5√2 . . . . rationalize the denominator

The length of one leg is 5√2 units, about 7.07107 units.

-5x + 6 less than 21

Musya8 [376]

Answer:

x > -3

Step-by-step explanation:

Step 1: Write inequality

-5x + 6 < 21

Step 2: Solve for x

Subtract 6 on both sides: -5x < 15
Divide both sides by -5: x > -3
