Answer:a) 870
b) 435
Step-by-step explanation:
a)
number of photos to be posted =n = 30
number of web pages on which they would be posted is 2
Since the order in which the photos appear on the web pages matters,
Number of ways = 30 permutation 2
=870 ways
b)
Since the order in which the photos appear on the web pages does not matter,
Number of ways = 30 combination 2
= 435 ways
Answer:
Thank you so much for this
Step-by-step explanation:
Have a nice day ! :)
14 = M each on would be *t=5
The interior angles of a 9-agon add up to (9 -2)*180° = 1260°. The sum of the given angles is
.. 1139° +x° = 1260°
.. x = 1260 -1139 = 121
The missing angle measure is 121°.
_____
The supplement of each interior angle is its corresponding exterior angle. The sum of exterior angles of any convex polygon is always 360°. Another way to approach this problem is to add the exterior angles.
In this question, it is given that
Marcus bought pumpkins that weigh 8 lb, 11 lb, 23 lb, and 15 lb.
And we have to find the mean weight .
To find the mean weight, we will first add all the weights, then divide them by number of pumpkins which is 4.
So the mean weight is
Therefore the mean weight is 14.25 lb .
