1 and 1/10
i think that is what it is
If the list is of numbers of students in each music class, and if their median is supposed to be 19, then the blank must represent the number 18. The number must be lower than 20, and must be 19 when averaged with 20. Its value must be ...
2*19 - 20 = 18
_____
Altogether there are 6 numbers, so the median (19) will be the average of the middle two. Three of the numbers are more than 19, so the other three must be less than 19. The lowest of the upper 3 numbers is 20, so 19 must be the average of 20 and the missing number, which must be 18.
Answer: The first rule: am × an = am+n. 3. 3. The second rule: (am)n = amn. 3. 4. The third ... three a's at the bottom can be divided out, so we are now left with a4. 1 that is a4. The same answer is obtained by subtracting the indices, that is, 7 − 3=4.
Step-by-step explanation:
Answer:
8% increase
Step-by-step explanation:
The length after the increase:
30 x 1.1 = 33cm
The width after the increase:
20 x 1.05 = 21cm
New perimeter:
2(33 + 21) = 108 cm^2
Old perimeter:
2(30 + 20) = 100 cm^2
Percentage increase of area:
108 / 100 = 1.08 = 8% increase
Answer: There is no way to get the answer that way, try using another form besides the X where you put the two numbers on either side to get the two numbers that go into (x+/-"?")(x+/-"?")
