Two local hotels, X and Y, rent out rooms nightly. Let X represent the number of rooms hotel X rents out nightly, and let y represent the number of rooms hotel Y rents out nightly. The mean of X is 49, and the mean of Y is 58. Which answer choice correctly calculates and interprets the mean of the sum, S = X+Y? 1 O Ns = 53.5; the hotels can expect to rent out 53.5 rooms, on average, each night. Ws = 53.5; on one randomly selected night, the total number of rooms rented out will be 53.5. Os = 107; the hotels can expect to rent out 107 rooms, on average, each night. ONs = 107; on one randomly selected night, the total number of rooms rented out will be 107. ​

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =

step-by-step explanation:

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
