Answer:
0.818
Step-by-step explanation:
Since the shipment has a ton of aspirin tablets, we can assume that we pick 13 of them <em>with</em> <em>reposition, </em>because the probability shoudn't change dramatically from the probability of picking without reposition if we do so.
We call D the amount of defective tablets. If we assume that we pick the tablets with reposition, then we obtain that D is a random variable of Binomial distribution with parameters 13 and 0.6 (the probability of picking a defective tablet).
We want D to be at most one. To calculate the probability of that event we add up the probability of D being equal to 0 and the probability of D being equal to one. Since D is binomial, we have
We conclude that
Hence, the shipment will be accepted with probability 0.818

3.
m/_QOR + m/_ROS = 90 (because the two angels together make a right angle)
Substitute.
x + 5 + 2x + 7 = 90
3x + 12 = 90
-12 -12
subtract 12 from both sides
3x = 78
Divide each side by 3 to get x by itself
x = 26
4. those two angles in the picture are vertical, which means they're congruent.
with that in mind...the ray makes a right angle on one and the other, w, you dont know. so to get the whole angle you need to add both angles to get the whole thing so...
m/_w + 90 = 125
subtract 90 on both sides
m/_w = 35
m/_QOR + m/_ROS = 90 (because the two angels together make a right angle)

x + 5 + 2x + 7 = 90
3x + 12 = 90
-12 -12
