a bag contains 10 white balls and 14 red balls.a ball is taken out of the bag,what is the probability that it is a red ball

Anit [1.1K]

Answer:

7/12

Step-by-step explanation:

Total = 10W+14R

probability of red = R/total

10+14 = 24 so total = 24

R = 14

14/24

reduce (divide by two on the top and bottom)

14/2

-------

24/2

= 7/12

Solve this system of equations algebraically: y – 10 = 11x + x2 y – 12x = 30

You can solve both equations for y and then set equal to each other. Then use the quadratic equation to solve for x

Can someone pleaseee help me

Nookie1986 [14]

Answer:

120 degrees

Step-by-step explanation:

Ok, so if you know that 5 is 120 degrees then 1 is 120 degrees because the angles will be corresponding when it is a set of lines that are parallel bisected by a line. So 1 is corresponding to 5 and 2 to 6 and 3 to 7 and 4 to 8.

Determine the end behavior of the polynomial function. f(x)=-3x^4-2x^3+2x^2+ 3x +5 a) falls to the left and rises to the right b

Molodets [167]

Answer:

Option b is correct

Step-by-step explanation:

In order to check the end behavior of a polynomial function we just check the leading term and its coefficient and the procedure is as follows:

Here we can see that highest exponent of the polynomial function is 4

therefore degree of the polynomial is 4. and therefore $-3x^4$ is leading term.

because of even degree it will be same from both ends that is either both sides rises or both sides falls. Since number in the front of leading is negative therefore it falls at both ends. that is falls to the left and falls to the right.

therefore option b is correct.
