N*(21/100)=(700/100)
n=(700/100)/(21/100)
n=(700/100)*(100/21)
n=700/21
n=33+1/3
So <em><u>thirty three</u></em> $0.21 pencils can be purchased for $7.00.
Answer:1.56
Step-by-step explanation:
For constant of proportionality of k,
y=(1/k)*x
If y =9,
9=7/k
K=7/9=0.78
y=0.78x
y=0.78*2=1.56
When x
Answer:
Option B) is a continuous probability distribution
Step-by-step explanation:
Properties of a normal probability distribution:
- The mean, mode and median of the data is same.
- It is a continuous probability distribution.
- The area under the curve is 1.
- The probability that any random variable X at a particular value is zero.
Thus, from the properties of normal distribution, the correct answer is:
Option B) is a continuous probability distribution
