Hi okay so if the original coords are a=(-2,0) b=(-3,-2) and c=(-5,-2), if one of the coords on the dilated triangle are (7,3), you apply that to the rest. so i think a=(7,3) b=(10.5,7) c=(17.5,7)but i’m not sure cause it says the constant is 4 but if you apply the constant of (7,3), the constant is -3.5. if you apple the constant of 4, the answers don’t really make sense.
answer: a=(7,3) b=(10.5,7) c=(17.5,7) i think
this question actually doesn’t really make sense at all. but i hope this helps lol.
I think all you need to do is rise/run, in this case, 2420÷6050=0.4=40%
Answer:
The critical value of <em>t</em> is 2.000.
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for population mean in case the population standard deviation is not known is:
The information provided is:
<em>n</em> = 57
Confidence level = 95%
As the sample size is large enough, i.e. <em>n</em> = 57 > 30 the sampling distribution of sample mean can be approximated by the normal distribution.
The distribution of sample statistic is normal and the sample size is quite large. This implies that it is appropriate to use a <em>t</em>-interval.
Compute the critical value of <em>t</em> as follows:
*Use a <em>t</em>-table for the critical value.
Thus, the critical value of <em>t</em> is 2.000.
