She had $3000. She spend 40% of the money in smart TV and 15% of the remainder on Game Set. (a) What % of the money had she left

Dovator [93]

Answer: She had left 54% of the money which is $1620.

Step-by-step explanation:

40% of $3000 = $1200

15% of $1200 = $180

$3000 - ($1200 + $180)

$3000 - $1380 = $1620

$1620 is the money she had left.

$1620 is 54% of $3000

She had 54% left of the money.

A continuous random variable X has cdf F(x)=x² b (a) Determine the constants a and b. for a < 0, for 0 < x < 1, for x &

Karolina [17]

Any proper CDF $F(x)$ has the properties

• $\displaystyle \lim_{x\to-\infty} F(x) = 0$

• $\displaystyle \lim_{x\to+\infty} F(x) = 1$

so we have to have a = 0 and b = 1.

This follows from the definitions of PDFs and CDFs. The PDF must satisfy

$\displaystyle \int_{-\infty}^\infty f(x) \, dx = 1$

and so

$\displaystyle \lim_{x\to-\infty} F(x) = \int_{-\infty}^{-\infty} f(t) \, dt = 0 \implies a = 0$

$\displaystyle \lim_{x\to+\infty} F(x) = \int_{-\infty}^\infty f(t) \, dt = 1 \implies b = 1$

I will give brainleist

Goshia [24]

Let's write the equation in standard from

$y = mx + b$

Where,

m is slope or rate of change
b is the y-intercept or initial value

<h3>Let's start by finding slope⤵️</h3>

$\boxed{ \sf \: m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1}}}$

x1, y1 = 0,12
x2, y2 = 1,13

$\tt \: m = \frac{13 - 12}{1 - 0}$

$\tt \: m = \frac{1}{1}$

$\tt \: m = 1$

b = 12

<h3>Equation⤵️</h3>

$\sf \: y = 1x + 12$
