We do this according to PEMDAS
The Parentheses here are do indicate what is in the exponent
We do the Exponent first
2^3 = 2*2*2 = 8
7(8)
There is an implied multiplication here

? = 3x
Step-by-step explanation:
2(? + 5) = 6x + 10

2*? = 6x
6x/2 = 3x
 
        
             
        
        
        
Answer:
0.6804
Step-by-step explanation:
Given that Margie is practicing for an upcoming tennis tournament. Her first serve is good 20 out of 30 times on average. 
Since each trial is independent and there are two outcomes, X no of good serves is binomial with n=6 and p =2/3
Required probability
= Prob that atleast four of 6 times good serve
=
=
Formula used:
P(X=r) =
 
        
                    
             
        
        
        
Money earned by restaurant on Friday=$1073
Money earned by restaurant on Saturday=$1108
Let Money earned by restaurant on Sunday=$x
 Average=$1000

Number of observation=3
                            ⇒  3×  1000=1073+1108+x
                             ⇒3000=     2 181+x
                               ⇒3000-2181=x
                             ⇒x=819
The restaurant needs to earn on Sunday to average $1000 per day over the three-day period=$819
