Answer:
The mean increases and the median changes to 4.
Step-by-step explanation:
To find the mean. You need to add all of the numbers together then divide by how many numbers there are. The median is found by the middle number.
Y is increased by 6 because if you imagine x being 3 then y would = 16 but if you increase x by 3 making 6 then y would = 22 and 16 increased by 6 is 22
9×7=63
63÷2=31.5
31.5×4=126
7×7=49
126+49=175
175 is the answer
.0091 rounded to the nearest hundredths is .01.
