Find each product. (5-x2+2)(-3) PLEASE HELP!!! ASAP!!!

Mathematics
1 answer:
Bumek [7]3 years ago
3 0

Answer:

3x^2 - 21 (did you mean for the equation to be (5 - x^2 + 2) \cdot -3?)

Step-by-step explanation:

Multiplying -3 by each term:

-3 \cdot 5 = -15

-x^2 \cdot -3 = 3x^2

-3 \cdot 2 = -6

-15-6 = -21

So the equation comes out to 3x^2 - 21 .

Hope this helped!

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

Answer:

140 cm²

Step-by-step explanation:

The height of the parallelogram is 10cm . And its base is 14cm .We know that the area of parallelogram is product of base and height .

⇒ Area = base × Height

⇒ Area = 14cm × 10cm

⇒ Area = 140 cm² .
