Answer:
38= 2×19
39= 3×13
40= 2×2×2×5
hcf = highest common factor = 1
if you can't seen any common factor then write 1 , it's common in all.
if all the number divide by same number, then it's common in factor
You first do the opposite of what 4 is. so subtract on both sides. next since y is already being divided by 5 you need to do the opposite which is multiplying. so multiply on both sides and your answer will be y=60
Answer:
0.001831055
Step-by-step explanation:
Here, n = 16, p = 0.5, (1 - p) = 0.5 and x = 14
As per binomial distribution formula P(X = x) = nCx * p^x * (1 - p)^(n - x)
We need to calculate P(X = 14)
P(x =14) = 16C14 * 0.5^14 *(1-0.5)^2
= 120 * 0.5^14 *(1-0.5)^2
= 0.001831055
We know, 1 lbs = 0.45 Kg
52 lbs = 0.45*52 = 23.58 Kg
Answer:
10
Step-by-step explanation:
First solve for x. HI = 2x, IJ = 4x - 10, and the whole length HJ = 4x.
So 2x + 4x - 10 = 4x.
6x - 10 = 4x
6x - 4x - 10 = 4x - 4x
2x - 10 = 0
2x - 10 + 10 = 0 + 10
2x = 10
x = 5.
IJ is 4x - 10, so it becomes 4(5) - 10
20 - 10 = 10
