What two numbers add to 10 and multiply to -192? How do you find it?I know I already asked this but I wasn't able to find the numbers. Please help me.

Answer 1

Answer: There is a way to do this algebraically using equations, but it is really messy so I am going to go over the way to do it. The way you do this is by finding whole numbers that multiply to make -192. Start with 1 and 192, 2 and 96, 3 and 64, etc and make the smaller number negative.
The reason why you make the smaller number negative is because we are looking for what numbers add together to make a positive number (10). If the bigger number was negative, then we would get a negative sum.
From what i could find, there aren't any whole numbers that satisfy this, and i doubt that the question would want you to find decimals for this.

The way to find this with equations (in short) is to have to variables, x and y, and make two equations. in this case x+y=10 and xy=-192. Solve one equation for a variable and then use substitution to plug that variable into the other equation. if you do this you get really long decimals.

What is the sum of the first 14 terms of the sequence -11+(-18)+(-25)+(-32)...-791
-483
-102
-714

Answers

the difference between -11 and -18 is -7
the difference between -18 and -25 is -7
the difference between -25 and -32 is -7

therefore we can say that the difference between all of the terms will be -7.

the first term is -11 -> call this a
the difference is -7 -> call this d
the number of terms is 14 -> call this n

use the equation (sum of) $_(n)$ = $(n)/(2)$ (2a + (n-1)d)

(sum of) $_(n)$ = $(14)/(2)$ (2 x -11 + (14-1)-7)

= -7(-22 + (13 x -7))
= -7(-22 + -91)
= -7(-111)
= 777

The right answer for the question that is being asked and shown above is that: "C. TUVW was rotated 90° counterclockwise about the origin and then translated 4 units to the right." This is the sequence of transformations was performed on figure TUVW to produce figure TꞌꞌUꞌꞌVꞌꞌWꞌꞌ

CAN SOMEONE PLEASE HELP I AM ALSO BEGGING! Probability theory predicts that there is a 76% chance of a water polo team winning any particular match. If the water polo team playing two matches is simulated 10,000 times, in about how many of the simulations would you expect them to win exactly one match?

Answers

In each of the two match simulations, the order in which one match is won and one match is lost does not matter. The probability of winning any particular match is 0.76 and the probability of losing any particular match is 1.00 - 0.76 = 0.24.
In each simulation the probability of winning exactly one match is:
$P(win\ exactly\ one)=2C1*0.76*0.24=0.3648$
Therefore in 10,000 simulations the expected number of times that exactly one match is won = 10,000 * 0.3648 = 3648 times.

3648

B. 2

C. 0 or 2

D. –2 or 2

Answers

By basic definition, the absolute value of a number determines just how far that number is from 0 on the number line. Because of that, the absolute value can never be a negative number, because the positive or negative number will have the same distance.

In the case of |p| = 2, p can either be -2 or 2. Among the choices, the correct answer is D.

Answer:

–2 or 2

Suppose P is between M and N. If MN = 10, MP = x-3, and PN = x+1, what is the value of x?

Answers

MN = MP + PN

10 = (x - 3) + (x + 1)

10 = x + x - 3 + 1

10 = 2x - 2 (add 2 to each side)

12 = 2x (divide 2 from each side)

12/2 = x
