2 1/8 - 1 2/7 = ?
8*2+1/8 - 7*1+2/7 =
17/8 + 9/7 =
8,7 | 2
4,7 | 2
2,7 | 2
1, 7 | 7
1, 1 | 1_______ 2*2*2*7 = 56
17/8 + 9/7 =
56÷8*17/56 + 56÷7*9/56 =
7*17/56 + 8*9/56 =
119/56 + 72/56 = 191/56
Answer:
191/56
Answer:
k = 4
Step-by-step explanation:
Given,
when , P(x) is divided by (x - 1) , the remainder = 0
⇒ 
hence, k = 4

the radius is 2.38
Step-by-step explanation:
use the formula c=2pi r
Answer:
0.497
Step-by-step explanation:
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
From the question :
n = 6 ; x = 3 ; p = 0.42
P(x = 3) +... P(x = 6)
P(x = 3) = 6C3 * 0.42^3 * (1 - 0.42)^(6-3)
P(x = 3) = 20 * 0.074088 * 0.195112
P(x = 3) = 0.28910915712
Then find p(x = 4).. + p(x = 6)
Using a calculator :
P(X >= x) = 0.497
