The sum of two numbers is 11 and their product is 128. find the numbers?

KatRina [158]

X+y=11
xy=128
x=11-y, so (11-y)y=128
11y-y²=128
y²-11y+128=0
use the quadratic formula to find y: y=(11+√391i)/2 or y= (11-√391i)/2
x=(11-√391i)/2, or x=(11+√391i)/2

so either there is an error in your question, or you have two unreal numbers:
(11-√391i)/2 and (11+√391i)/2

The following data were given in a study of a group of 1000 subscribers to a certain magazine. In reference to job, marital stat

kozerog [31]

Answer:

$(a)$ $P(M\ or\ P\ or\ C) = 1.307$

(b) See Explanation

Step-by-step explanation:

Given

$P = 312$ ---- Professionals,

$M = 470$ ----- Married persons,

$C = 525$ ---- College graduates,

$PCG = 42$ ----- Professional college graduates,

$MCG = 147$ ----- Married college graduates,

$MP = 86$ ---- Married professionals,

$MPCG = 25$ ---- Married professional college graduates

$Total =1000$

Solving (a): P(M or P or C)

This is calculated as:

$P(M\ or\ P\ or\ C) = P(M) + P(P) + P(C)$

$P(M\ or\ P\ or\ C) = \frac{n(M) + n(P) + n(C)}{Total}$

$P(M\ or\ P\ or\ C) = \frac{470 + 525 + 312}{1000}$

$P(M\ or\ P\ or\ C) = \frac{1307}{1000}$

$P(M\ or\ P\ or\ C) = 1.307$

(b) In probabilities, the probability of an event or collection of events must not exceed 1 and must not go below 0.

In (a) above, the calculated probability exceeds 1.

Because of this single reason, the collected data is incorrect

HELP ME PLEASE!!<br> If y varies directly as x, and k = 12. Find x when y = 6.

zaharov [31]

Formula: Y=kx or y=ax or Y/x=a

K=12 k is also the slope!
Slope=12
Y=6
So If you plug in these values you get:
6=12x

Answer:
X=0.5 or 1/5
