These are exponents. To solve an exponent you need to multiply the base it self how many times its says in the power.
a² 
a = base
<span>2 = power
</span>
7^5 = 7 × 7 × 7 × 7 × 7 = <span>16807
7^5 = </span><span>16807</span>

Answer:
0.010
Step-by-step explanation:
We solve the above question using z score formula
z = (x-μ)/σ, where
 x is the raw score = 63 inches
μ is the population mean = 70 inches
 σ is the population standard deviation = 3 inches
For x shorter than 63 inches = x < 63
Z score = x - μ/σ
= 63 - 70/3
= -2.33333
Probability value from Z-Table:
P(x<63) = 0.0098153
Approximately to the nearest thousandth = 0.010
Therefore, the probability that a randomly selected student will be shorter than 63 inches tall, to the nearest thousandth is 0.010.
 
        
             
        
        
        
You forgot to post the function
        
                    
             
        
        
        
The range is 30 to find the range u subtract the biggest from the smallest so 81-51=30 hope this helps
