Option B. because all rational numbers are integers.
Have a look at the above venn diagram showing the relationship between - Real, irrational, rational, integers, whole and natural numbers.

Standard form: 314,207
expanded form: 300,000+10,000+200+7
word form: three hundred fourteen thousand, two hundred seven
Answer:
12
Step-by-step explanation:
(6)² = 3x
then x= 36/3
x= 12
-48 plugging in everything and using PEMDAS it should be -48
Answer:
81.8%
Step-by-step explanation:
Mean = 
Standard deviation = 
Now we are supposed to find out what percent of the numbers fall between 35 and 50

Substitute the values

Now for P(35<x<50)
Substitute x = 35


Substitute x = 50


So, P(-1<z<2)
P(z<2)-P(z<-1)
=0.9772-0.1587
=0.8185
= 
=81.8%
Hence 81.8% percent of the numbers fall between 35 and 50
