260 students is the prediction for how many sweatshirts will be sold so no they will not sell all of them
Answer:
angle 1=
°
Step-by-step explanation:
to find the angle of 1 you should know angle 2, what is angle 2?
angle 
° and angle 
are symetrical so they have the same value.
now that we know that angle 2 is equal to °
then what is angle 1
if the whole line has an angle of 
° and angle °.
so the equation will be :
flip the equation to find 
:
the angle 1 which we found in the given equation is 135
check if my answer is correct is :
my equation is correct
Those are the ranges for one tandard deviation below the mean and one standard deviation above the mean, and we know that 68% of the data falls in that range, so the probability that a randomly chosen worker makes that much is 68%
