In number terms it would be -377=X-1000 and the answer to that would equal 623 because to find out what X equals we must add -377 and 1000 which equals 623 so the answer would be -377=623-1000 to double check do the math problem and see :) hope this helped

Answer: 95% confidence interval = 20,000 ± 2.12 $\times$ $\frac{1500}{\sqrt{17} }$

( 19228.736 , 20771.263 ) OR ( 19229 , 20771 )

Step-by-step explanation:

Given :

Sample size(n) = 17

Sample mean = 20000

Sample standard deviation = 1,500

5% confidence

∴ $\frac{\alpha}{2}$ = 0.025

Degree of freedom ( $d_{f}$ ) = n-1 = 16

∵ Critical value at ( 0.025 , 16 ) = 2.12

∴ 95% confidence interval = mean ± $Z_{c}$ $\times$ $\frac{\sigma}{\sqrt{n} }$

Critical value at 95% confidence interval = 20,000 ± 2.12 $\times$ $\frac{1500}{\sqrt{17} }$

( 19228.736 , 20771.263 ) OR ( 19229 , 20771 )

Y= (x - 2)²-7 how do I graphic this<br>

WITCHER [35]

Hmmm it would be kind of hard to graph as it will be a curved line but the middle of the line would be at (2,-7). Not (-2,-7).

And it will be curving upwards, meaning it will start by going down and end by going up.

Hope this helps some.

Answer:

c = √85

c = 9.2

Step-by-step explanation:

a² + b² = c²

7² + 6² = c²

49 + 36 = c²

85 = c²

c = √85

c = 9.2
