Answer:

20

Step-by-step explanation:

\displaystyle \frac{39(100)+x}{40}=98\\\\3900+x=3920\\\\x=20

Therefore, the remaining student scored a 20 (which sounds weird, but I'm going with it).

Solve for x.
Rudiy27
5x^2 - 80 = 0

x^2 = 80/5
x^2 = 16
x = sqrt 16
x = (4,-4) <===

If the correlation coefficient is 0.96, how confident can you be that your predicted value for the cost of a call at 70 minutes

Very confident because a correlation coefficient of 1 is perfect then a correlation coefficient of .96 means it is like 96% accurate

Is triangle COW ~ triangle PIG identify the similarity postulate or theorem that applies
ch4aika [34]
We can see that OW/IG = 5/15 = 1/3 and CW/PG = 7/21 = 1/3. So we have two ratios that result in the same value (1/3). We would need to know if CO/IP is also 1/3 as well, so we can use the SSS similarity theorem. However we don't have that information. So we can't use SSS. 

Alternatively, if we knew that angle CWO = angle PGI, then we can use the SAS similarity theorem. But that bit of info isn't given to us, so we can't use SAS either.

AA can't be used because we don't know anything about any pairs of angles. 

-------------------------------------------------------------------------

In short, the answer is choice D. It cannot be determined. There isn't enough information.
