Answer:
0.42
Step-by-step explanation:
move the decimal point 2 to the left
A is at (2,-2). after 90 degree counter clockwise, it is at (2,2). Then, a transformation one unit to the left gets it to A', (1,2)
A)
Answer:
The upper bound is 399.5
Step-by-step explanation:
Let's start by calculating the mean value of the distribution as the addition of all values given divided by 12:
Average = 289.75.
If the standard deviation is 56, then the upper bound in 95% the confidence interval for the mean price of the phones is going to be given by the mean value added to 56 times 1.96 (since 95% of the population is withing 1.96 times the standard deviation)
That is: 289.75 + 56 * 1.96 = 399.51
which rounded to one decimal place gives: 399.5
the sum of the expanded angle is 180⇒
