Answer:
-5
Step-by-step explanation:
-7 - (-2)
-7 + 2
Example: If you owe someone $7, and you give them $2, how much do you still owe? You are owing him $7 so it's a negative and you give him $2 which is a negative as well since you are giving it to him. So, to answer how much do you still owe, you would add $2  to the $7 you owed, so now, you owe him $5, which is a negative since you OWE him.
Hope this helps:)
 
        
             
        
        
        
Answer:
probability that a randomly selected page that contains only text will contain no typos that is 
P(x=0) =  = 0.923
 = 0.923
Step-by-step explanation:
<u>Poisson distribution</u>:-
Explanation of the Poisson distribution :-
The Poisson distribution can be derived as a limiting case of the binomial 
distribution under the conditions that 
i) p is very small
ii) n is very large
ii) λ = np (say finite
The probability of 'r' successes = 
Given the average number of typos ∝ = 0.08 per page.
probability that a randomly selected page that contains only text will contain no typos that is = 
After calculation P(x=0) =  = 0.923
 = 0.923
probability that a randomly selected page that contains only text will contain no typos =0.923
 
        
             
        
        
        
Answer:
 The total cost for  each health club will be the same after 4 months.
Step-by-step explanation:
- Let A = membership fee for studio A
- B = membership fee for studio B
We want to when the total cost at each health studio is the same.
In other words, when A = B.
Therefore, the expression becomes


Step 1: Simplify both sides of the equation.

Step 2: Subtract 18.25x from both sides.


Step 3: Subtract 22 from both sides.


Step 4: Divide both sides by 6.25


Therefore, the total cost for  each health club will be the same after 4 months.
