If one serving takes 3/8 of a cup and she wants two servings, just multiply 3/8 by 2.
2 * (3/8) = 6/8 or 3/4 of a cup.
        
             
        
        
        
Answer:
a) 18 cm
b) 18
c) 3
The Earl's height is unusual because the  z score does not lies in the given range of usual i.e -2 and 2
Step-by-step explanation:
Given:
Mean height, μ = 174 cm
Standard deviation = 6 cm
height of Earl, x = 192 cm
a) The positive difference between Earl height and the mean = x - μ
= 192 - 174 = 18 cm
b) standard deviations is 18 
c) Now, 
the z score is calculated as:

or

or
z = 3
The Earl's height is unusual because the  z score does not lies in the given range of usual i.e -2 and 2
 
        
             
        
        
        
Answer:
base = 15 units
Step-by-step explanation:
We are given area of a triangle = 52.5 sq. units
Height is given as 7 and we have to find the base.
Using formula for area of triangle:
Area of triangle = 
 
 
52.5 * 2 = base × 7
105 = base × 7
base = 15
 
        
                    
             
        
        
        
Answer:
y=69
Step-by-step explanation:
first step:when y=26 and x=21
c=y-x
c=26-21
c=5
second step: when y is unknown and x=64
To find y we simply add the value of c to x
y=x+c
y=64+5
y=69
