Tamiku [17]

Answer:

90 Confidence Interval for the proportion = [ 0.216,0.334]

Step-by-step explanation:

The confidence interval for proportion formula =

p ± z × √p(1 - p)/n

Where p = x/n

x = 42

n = number of samples = 153

p = 42/153

p = 0.2745098039 ≈ 0.275

z = z score of 90% confidence interval = 1.645

Confidence interval =

0.275 ± 1.645 × √0.275 - ( 1 - 0.275)/153

= 0.275 ± 1.645 × √0.0013031046

= 0.275 ± 0.0593820985

Confidence Interval

= 0.275 - 0.0593820985

= 0.2156179015

≈ 0.216

= 0.275 + 0.0593820985

= 0.3343820985

≈ 0.334

90 Confidence Interval for the proportion = [ 0.216,0.334]

Hi there, hope everyone is well and staying cool :D
gogolik [260]

Answer:

A) By using the Pythagorean Theorem, we will see that 8^2 + 15^2 = 17^2. If we simplify it, we will find that the hypotenuse of ΔABC = 17

B) approximately 18.79

Step-by-step explanation:

A) In all honesty, you don't really need to look at ΔACD at all for this one. Just use the Pythagorean Theorem (like previously stated) and solve!

***Pythagorean Theorem is  leg^2 + leg^2 = hypotenuse^2

B) Here, you can also use the Pythagorean Theorem! However this time, the equation will be, 8^2 + 17^2 = AD.  

  • 8^2 + 17^2 = 64 +289
  • 64 + 289 = 385
  • \sqrt{385} \\ ≈ 18.79

Hope you do well on the rest of your math problems :D
