Answer:
1.5 in
Step-by-step explanation:
Let x be the width of the frame.
Side of print=10 in
Area of frame=69 square in
We have to find the width of the frame.
Side of frame=10+x+x=10+2x
Area of square=
By using the formula
Area of print=
Area of frame with print=
Area of frame=Area of frame with print-Area of print
Because Side is always positive.
Hence, width of frame=1.5 in
Answer:
sqrt(360)
Step-by-step explanation:
sqrt(360)=sqrt(36*10)=sqrt(36)*sqrt(10)=6*sqrt(10)
1 is 25
2 is 7.42

Answer:
C a dilation will always produce similar figures
Step-by-step explanation:
If the scale factor is >1 then the figure will get larger
< 1 the figure gets smaller
=1 it is congruent
We can rotate the figure but that is not by dilation. dilation does not change the orientation, unless the scale factor is negative( which is a reflection)
Answer:
Step-by-step explanation:
A. Two measurements(AandB)are taken on the same round.\oIs there a difference in the measurement of the muzzle velocity between device A and device B at the α=0.01 level of significance? Note: A normal probability plot and boxplot of the data indicate that the differences are approximately normally distributed with no outliers.
B. Construct a 99% confidence interval about the population mean difference. Compute the difference as device A minus device B. Interpret your results. The confidence interval is (__,__)?
Answer:
Open chart in StatCrunch --- Stat --- T Stats --- Paired --- Enter values: Sample 1 = A, Sample 2 = B --- Click on Confidence Interval… and enter Level which is my #%. --- Compute
