Answer:
1/10x * 1/10x
Step-by-step explanation:
Writing a term with negative exponents is the same as putting it in a fraction.
10x^-1 = 1/10x
so the expression would be
1/10x * 1/10x
 
        
             
        
        
        
Answer:
x = 7
y = 2
Step-by-step explanation:
In the above question, we are given 2 equations which are simultaneous. To solve this equation, we have to find the values of x and y
x + 3y = 13 ........ Equation 1
x - y = 5...........Equation 2
From Equation 2,
x = 5 + y
Substitute 5 + y for x in Equation 1
x + 3y = 13 ........ Equation 1
5 + y + 3y = 13
5 + 4y = 13
4y = 13 - 5
4y = 8
y = 8/4
y = 2
Since y = 2, substitute , 2 for y in Equation 2
x - y = 5...........Equation 2
x - 2 = 5
x = 5 + 2
x = 7
Therefore, x = 7 and y = 2
 
        
             
        
        
        
Answer:
The p-value would be 0.0939
Step-by-step explanation:
We can set a standard t-test for the Null Hypothesis that 
The test statistic then takes the form 

with this value we then can calculate the probability that is left to the right of this value  . From theory we know that t follows a standard normal distribution. Then
. From theory we know that t follows a standard normal distribution. Then  which is smaller than the p-value set by Breyers of 0.10
 which is smaller than the p-value set by Breyers of 0.10
