For this item, any answers that are not whole numbers should be entered as a decimal, rounded to the tenths place. brian's school locker has a three-digit combination lock that can be set using the numbers 5 to 9 (including 5 and 9), without repeating a number. the probability that the locker code begins with a prime number is %. the probability that the last digit of the locker code is an odd number is %.

Step-by-step explanation:

The possible combinations are

1*4*3 (with 5) +  1*4*3(with 7) = 24

Total combinations are 5*4*3=60

(24/60)*100 = 40 %

     2. Odd numbers are those which don't divide with 2. So in this case it is 6 and 8.

The possible combinations are

1*4*3 (with 6) +  1*4*3(with 8) = 24

Total combinations are 5*4*3=60

(24/60)*100 = 40 %

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
