Please look at this question, thanks

Oxana [17]

Answer:

6x+2y+3=0

Step-by-step explanation:

y=-3x-(3/2) add 3x

y+3x=-(3/2) divide -1

-y-3x=3/2 multiply 2

-2y-6x=3 subtract 3

-2y-6x-3=0 multiply -1

2y+6x+3=0 rearrange

Can someone help me with this substitution method for algebra Y=4*-3x 5x-y=22

alexira [117]

$y=4-3x\\
5x-y=22\\\\
5x-(4-3x)=22\\
5x-4+3x=22\\
8x=26\\
x=\dfrac{26}{8}=\dfrac{13}{4}\\\\
y=4-3\cdot\dfrac{13}{4}\\
y=4-\dfrac{39}{4}\\
y=\dfrac{16}{4}-\dfrac{39}{4}\\
y=-\dfrac{23}{4}\\\\
\boxed{(x,y)=\left(\dfrac{13}{4},-\dfrac{23}{4}\right)}$

A surgical technique is performed on seven patients. You are told there is a 70% chance of success. Use a table to find the prob

kiruha [24]

Answer:

31.77% probability the surgery is successful for exactly five patients.

Step-by-step explanation:

For each patient, there are only two possible outcomes. Either the surgery is successful, or it is not. The probability of the surgery being successful for a patient is independent of other patients. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
