The answer for x is 6

The answer would be x=6
to find it you would set 3x-2 equal to 2x+4 and solve because the two sides would be equal if the triangles are congruent
hope this helps :)

tatuchka [14]

Answer:

With a .95 probability, the margin of error is = 0.392

Step-by-step explanation:

Given -

In order to estimate the average time spent per student on the computer terminals at a local university, data were collected for a sample of 81 business students over a one-week period.

Sample size ( n ) =81

Standard deviation $(\sigma )$ = 1.8 hours

$\alpha$ = 1 -.95 =.05

$Z_{\frac{\alpha }{2}}$ = $Z_{\frac{.05 }{2}}$ = 1.96 (Using Z table)

With a .95 probability, the margin of error is

Margin of error = $Z_{\frac{\alpha }{2}}\frac{\sigma }{\sqrt{n}}$

= $Z_{\frac{.05 }{2}} \frac{1.8 }{\sqrt{81}}$

= $1.96\times 0.2$

Margin of error = 0.392

Jeff can paint 28 sqaure feet every 30 mintues angela can paint 50 square feet every hour who can paint faster,and by how many s

Gnesinka [82]

Answer:

6/1 square feet per hour. Jeff can paint faster.

Step-by-step explanation:

So, to get Jeff's square feet to 60 minutes, you do 30x2= 60. So, you do that to 28. 28x2= 56. 56/1 is greater then 50/1. So 56-50= 6. Jeff can paint 6 square feet per hour, greater than Angela.

Hope this helped!
