Answer:
C = 6
D = 10
Step-by-step explanation:
C + 5 = 11
C + 5 -5 = 11 -5
C = 6
D + 4 = 14
D + 4 -4 = 14 -4
D = 10
Answer:
Step-by-step explanation:
3x-4y+2=9
-4y= -3x +7
y=3/4 x -7/4
When y=0
0=3/4 x - 7/4
3/4x = 7/4
x=7/3
Therefore solution is (7/3, 0)
Answer:
greatest common factor is 2
Step-by-step explanation:
4k, 18k^4, 12
To find greatest common factor , we write each term in factor form
factors form are the product of the factor of given term
4k ---> 2 * 2* k
18k^2 ----> 3 * 3* 2* k*k
12 -----> 2*2*3
all the three terms has common factor 2
So GCf is 2
Answer:
Part a)
Given that
Thus the probability that a randomly selected clock lasts for at most 6 years is
Part b)
The probability that a clock lasts between 6 to 9 years equals
f(9)-f(6)
Thus probability becomes 0.818-0.75 = 0.0681
part c )
