<h3>Solution</h3>

Given :-

Paul is exactly 6yrs older than jane.
jane.the ratio of their ages is5:3

Find :-

Age off paul.

<h3>Explanation</h3>

Let,

Age of paul = x years
Age of jane = y years

According to question

==> x = 6 + y

==> x - y = 6_____(1)

And,

==> x : y = 5:3

==> x/y = 5/3

==> 3x - 5y = 0______(2)

Multiply by 3 in equ(1)

==> 3x - 3y = 18_____(3)

Subtract equ(2) & (3)

==> -5y + 3y = -18

==> -2y = -18

==> y = 18/2

==> y = 9

keep in equ(2)

==> 3x - 5×9 = 0

==> 3x = 45

==> x = 45/3

==> x = 15

<h3>Hence</h3>

Age of paul = 15 year

Determine whether the events are independent (I) or dependent (D). Place your answer in the blank provided. 1. Ramiro draws a ma

Stels [109]

Answer:

Independent events

Step-by-step explanation:

Given that:

Ramiro draws a marble from a jar without replacement and then flips a coin

Let $E_1$ be the event that Ramiro draws a marble without replacement and;

Let $E_2$ be the event of flipping a coin.

Let's have an analogy so that we can better understand the concept of independent and dependent events.

Consider a random experiment in which a marble is drawn from a jar without replacement and a fair coin is flipped together.

The event $E_1$ does not in any way affect the event $E_2$ of a head or a tail showing up in a flip of a coin.

Therefore, we say that $E_1$ and $E_2$ are independent events.

Suppose the event $E_1$ affects or influence the event $E_2$ , then we can say they are dependent events.

When will the equation p(b)=520(0.88)^b have a value less than 100?

yulyashka [42]

Answer:

The given equation will have value less than 100 whenever the value of b is greater than 12.89

Step-by-step explanation:

For the given equation, p(b) = 520 × $0.88^{b}$ to have a value less than 100 we can establish inequality as:

p(b) < 100

or, 520 × $0.88^{b}$ < 100

or, $\frac{520}{520}$ × $0.88^{b}$ < $\frac{100}{520}$

or, $0.88^{b}$ < $\frac{1}{5.2}$

or, ㏒ ( $0.88^{b}$ ) < ㏒ ( $\frac{1}{5.2}$ )

or, b× ㏒ 0.88 < ㏒ ( $\frac{1}{5.2}$ )

or, $\frac{log (\frac{1}{5.2}) }{log (0.88)}$ < b

or, 12.89 < b

Hence for the equation to have value less than 100, b must be greater than 12.89.
