7) Write the decimal number as a fraction
(over 1)
2.18 = 2.18 / 1

Multiplying by 1 to eliminate 3 decimal places
we multiply top and bottom by 3 10's

Numerator (N)
N = 2.18 × 10 × 10 × 10 = 2180
Denominator (D)
D = 1 × 10 × 10 × 10 = 1000

N / D = 2180 / 1000

Simplifying our fraction

= 2180/1000

= 109/50

= 2  9/50

8)7 ^{-5}  =  \frac{1}{7^{5}}

Answer:

B. Median

D. IQ R

Step-by-step explanation:

from the given data :

mean = 12.6364 , median =13,

st. dev = 5.6262

Q3 = 18 , Q1 = 8

IQ R = Q3 - Q1 = 18-8 = 10

One of the 18s should be 16 then,

mean = 12.4545, median = 13,

st. dev = 5.4656

Q3 = 18 , Q1 = 8

IQ R = Q3 - Q1 = 18-8 = 10

So, median and IQ R will not need to be changed
