Answer:

LCM of 4 and 10 is 20

Step-by-step explanation:

TO Find the LCM or Least Common Multiple we have to factor the numbers into smallest possible values bu using prime Numbers

(prime Numbers are 2,3,5,7 , .....)

factorization of numbers are

4 = 2 * 2

10 = 2 * 5

Now

Common factor between 4 and 10 is 2

Common factor will be written once because it is common in between both so

LCM = 2 * 2 * 5

(one two was common in both and on two was only in factor of 4 and not in 10)

multiplying gives

LCM = 20

Solve t/he system of linear equations given by x + y = 1 and ax − by = c, where a, b, c are real numbers. Note: The solution in

Phantasy [73]

Answer:

see explanation

Step-by-step explanation:

Given the 2 equations

x + y = 1 → (1)

ax - by = c → (2)

In (1) subtract y from both sides

x = 1 - y → (3)

Substitute x = 1 - y into (2)

a(1 - y) - by = c ← distribute left side

a - ay - by = c ( subtract a from both sides )

- ay - by = c - a ( multiply through by - 1 )

ay + by = a - c ← factor out y from each term on the left side

y(a + b) = a - c ← divide both sides by (a + b)

y = $\frac{a-c}{a+b}$ ← substitute into (3)

x = 1 - $\frac{a-c}{a+b}$ = $\frac{a+b}{a+b}$ - $\frac{a-c}{a+b}$ = $\frac{a+b-a+c}{a+b}$ = $\frac{b+c}{a+b}$

The ratio of pencil to rulers is 6:10. the are 21 pencils. how many rulers are there

Reika [66]

There would be 35 rulers.

In order to solve this, use cross multiplication.

6/10 = 21/x -----> cross multiply

10*21 = 6*x

210 = 6x

35 = x

Suppose a shipment of 190 electronic components contains 3 defective components. To determine whether the shipment should be ac

PolarNik [594]

Answer:

0.0467

Step-by-step explanation:

Probabilty of being defective is $\frac{3}{190}$

So probability of being good is $\frac{187}{190}$

Now,

Probability that all 3 of them are good is:

$\frac{187}{190}^{3}=0.9533$

Now, to find probability of rejection, we subtract the now found probability from 1. Thus, we have:

1 - 0.9533 = 0.0467
