Number of customers = 300
Number of customers that are male and has an open-toe shoes = 11
P(male and open-toe) = 11/300
Number of customers that are male = 139 + 11 = 150
Number of customers that are male and has an open-toe shoes = 11
Given that the customer is male,
P(open-toe) = 11/150
No, the two probabilities are not the same. The first probability has 2 variables - the gender and the shoe-type. The second probability has only 1 variable - the shoe-type

67
Step-by-step explanation:
PEMDAS
(X-2)(x^2-6x+2) so yes, (x-2) is in there
Answer:
131 minutes, an = 15 + (n - 1)(4)
Step-by-step explanation:
each time she is increasing by 4 minutes
we can write this equation like this since we have the difference and the first part:
an = 15 + (n - 1)(4)
note
"an" (or ace of n)'s n is in subscript and is written just like a superscript but on the bottom
we can plug in this equation to find ace of 30 (a30)
15 + (30 - 1)(4)
15 + 29*4
116 + 15
a30 = 131
The word mean is a synonym for average. To find the average, you add all of the data, then divide by the amount of data received.
So, we add 2+4+3+5+4+6+5+3+6+3+7+0+8+1. That totals to 57. Then, we divide by 14 because there are 14 answers. The end result is 4.07, because we round up.
