One number is five more than two times another. If there sum is decreased by one, the result is sixteen. Find the numbers.

1 answer:

6 0

First no. = x
Second no. = y

Equation Formation.
x = 2 y + 5
x - 2 y = 5.........equation (i)

x + y - 1 = 16
x + y = 17............. equation(ii)

Solving Equation
x + y = 17
x - 2 y = 5
⇅
3 y = 12
y = 4

x = 2 y +5
x = 2(4) + 5
x = 13

Answer = 4 , 13

Inessa [10]

The probability according to the given scenario is:

(a) 0.0395

(b) 0.95

(c) 0.076

The given values are:

$P(B/A) = 0.79$
$P(A) = 0.05$

(a)

The probability that the b/w has tuberculosis as well as having (+) test will be:

→ $P(A \cap B) = P(B/A).P(A)$

By substituting the values, we get

→ $= 0.79\times 0.05$

→ $= 0.0395$

(b)

The probability that a person does not have tuberculosis will be:

→ $P(A') = 1-P(A)$

→ $=1-0.05$

→ $= 0.95$

(c)

The person does not have tuberculosis as well as have a (+) test, the probability will be:

→ $P(A' \cap B) = P(A').P(B/A')$

→ $= 0.95\times 0.08$

→ $= 0.076$
