Answer:
0.1938 = 19.38% probability that a package is delivered by UPS if it weighs 2 lbs or more
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: It weighs 2 lbs or more
Event B: Delivered by UPS
15% of the packages that are delivered by UPS weighs 2 lbs or more.
This means that
More than 2 lbs:
15% of 20%(UPS)
93% of 80%(Not delivered by UPS). So
a. What is the probability that a package is delivered by UPS if it weighs 2 lbs or more
0.1938 = 19.38% probability that a package is delivered by UPS if it weighs 2 lbs or more
Answer:
the answer could be 100 metre
(1) The stem and leaf plot is a table organized by the first few (stem) digits with leaves (the rest digits) listed in corresponding rows. The solution depend on how your teacher expects stems to be defined (how many digits). Here's a link describing how to construct them. It is fairly straight-forward. https://www.mathsisfun.com/data/stem-leaf-plots.html
(2) the distribution (see image) is not really strictly symmetric. so I would choose (B)
(3) the distribution (see 2nd image) might be seen as "roughly normal" especially looking at the available options, choice (C) is the only plausible.
Answer:
option 2 , 3 , 4 , 5
Step-by-step explanation:
Use Pythagorean theorem
hypotenuse² = base² + altitude².
If the lengths satisfies Pythagorean rule, then they form a right angle triangle.
2) 41² = 40² + 9²
1681 = 1600 + 81
1681 = 1681
41, 40 , 9 will form a right angle as it satisfies Pythagorean rule.
3) 15² = 12² + 9²
225 = 144 + 81
225 = 225
9, 12 , 15 will form a right angle as it satisfies Pythagorean rule.
4) 17² = 15² + 8 ²
289 = 225 + 64
289 = 289
17, 15 , 8 will form a right angle as it satisfies Pythagorean rule.
5)53² = 28² + 45²
2809 = 784 + 2025
2809 = 2809
53 , 28 , 45 will form a right angle as it satisfies Pythagorean rule.
