Answer:
its not so clear but im guessing u r trying to solve the missing spaces so:
Step-by-step explanation:
1st since angle y is VERTICLE (across) from the angle that is 45 degrees angle y is also 45 degress.
and angle z is the same as teh one across from it which is 21
but this is also very odd since teh shape should add up to 360 degrees
6x2 + 13x + 6 = (<span>2x + 3)(3x + 2)</span>
At 95% confidence interval, true population mean is given by
x+/- 2sd
where x= sample mean and sd = sample standard deviation
True mean of population = 13.50 +/- 2*1.51 = 13.50+/-3.02
Interval: 13.50+3.02, 13.50-3.02 = 16.51, 10.48
