Answer:

The correct solution is "0.127128".

Step-by-step explanation:

The given values are:

p = 0.31

n = 20

Now,

$p(8$

$=20C_{9}(0.31)^9\times (0.69)^{11}+20C_{10}(0.31)^{10}\times (0.69)^{10}+20C_{11}\times (0.31)^{11}\times (0.69)^{9}$

$=0.074955+0.037043+0.015130$

$=0.127128$

Help find x. I believe it’s 13

Answer:

m∠RST = 155°

m∠RSU = 102°

Step-by-step explanation:

m∠RST = m∠RSU + m∠UST

12x - 1 = 9x - 15 + 53

12x - 9x = 1- 15 + 53

3x = 39

x = 39/3

x = 13°

m∠RST = (12x -1)° = (12 * 13 - 1)° = (156 - 1 )° = 155°

m∠RSU = (9x -15)° = (9 * 13 - 15)° = ( 117 - 15)° = 102°

I need to know how to make it in its simplest form

Multiply denominator by whole number then add that number to the nominator. Which would be 5 times 1 plus 3. SO 5+3 IS 8 and you keep the denominator so the first one is 8/5
