what is the standard deviation of the number of A Recoveries among 48 patients when the probability of Recovering is 0.75​

Answer»

ANSWER:

The answer is 3.

Step-by-step explanation:

Standard deviation = √npq

Where "n" is the number of PATIENTS = 48

"p" is the CHANCES of success = 0.75

"q" is the chance of failure = 0.25

Therefore,

Standard deviation = √ 48 X 0.75 x 0.25  

                             = √9 = 3

Thus the value of standard deviation is 3.

Answer»

Answer:

FOLLOWING answer

Step-by-step EXPLANATION:

Let a = x - y, b = y - Z, c = z - x

Here, a + b + c = x - y + y - z + z - x = 0

Factorise the following 2y cube + y square - 2y - 1please doo fasttt​

Answer»

ANSWER:

FACTORS of 2y³ + y² -2Y -1 are (y +1 ) , (2y + 1) and (y - 1)

Step-by-step explanation:

2y³ + y² - 2y - 1

= 2y³ + 2y² -y² - y - y -1

= 2y²(y + 1) -y(y + 1) - 1(y + 1)

= (y +1 )(2y² - y - 1)

= (y + 1){2y² - 2y + y - 1}

= (y + 1){2y(y -1 ) + 1(y - 1)}

=(y +1 )(2y +1 )(y -1)

HENCE, factors of 2y³ + y² -2y -1 are (y +1 ) , (2y + 1) and (y - 1)

1) If following angles make a linear pair, find the value of q. (7q-46) (4q-16) 2) In the adjoining figure the value of x is(3x+20)/(4x-36)​

Answer»

ANSWER:

Step-by-step EXPLANATION:

Linear pair MEAN the sum of TWO angles is 180.

We can use linear equation.:-

(7q-46) + (4q-16) = 180

7q-46+4q-16 = 180

11q-62 = 180

11q = 180+62

11q = 242

q = 242/11 = 22 ANS.
