Answer:
7x (times) 8
Step-by-step explanation:
(3x+6)(4x+2)
(3x + 4x)(6 + 2)
7x (times) 8
 
        
                    
             
        
        
        
The program is an illustration of loops
<h3>What are loops?</h3>
Loops are program statements that are used to perform repetition
<h3>The main program</h3>
The program written in Python, where comments are used to explain each line is as follows:
#This initializes sum to 0
summ = 0
#This gets input for the first number
num = int(input())
#This is repeated while num is not -1
while num!= -1:
    #This calculates the sum
    summ+=num 
    #This gets input for the num
    num = int(input())
#This prints the sum
print(summ)

Answer:
a) Mean=0 and Standard deviation=1
b) The z-scores have no units of measurement
Step-by-step explanation:
When we convert all the pulse rates of women to z-scores using the formula;
 the mean is 0 and the standard deviation is 1.
 the mean is 0 and the standard deviation is 1.
The reason is that, the resulting distribution of z-scores forms a normal distribution which has a mean of 0 and a standard deviation of 1.
b) The z-scores are standardize scores and has no units of measurement. They give us how many standard deviations below or above the mean of the corresponding values.
 
        
             
        
        
        
C. 3x + 7 because you can factor out the other 3.
a. 16+4x=4(4+X)
b. 25x+30y=5(5x+6y)
d. 40x-30y = 5(8x-6y)
hope this helps!
