Answer:

(x+2)(x+10)

Step-by-step explanation:

The given trinomial needs to be factorised. On the basis of degree of power of polynomial it can also be called a quadratic polynomial . General form is ax² + bx + c .

= x² + 12x + 20

By splitting middle term .

= x² + 10x + 2x + 20

Taking x and 2 as common.

= x ( x + 10 ) + 2( x + 10 )

Talking (x + 10) as Common .

= ( x + 2)( x +10)

<h3><u>Hence</u><u> </u><u>the</u><u> </u><u>factorised</u><u> </u><u>form</u><u> </u><u>is</u><u> </u><u>(</u><u>x</u><u>+</u><u>2</u><u>)</u><u>(</u><u>x</u><u>+</u><u>1</u><u>0</u><u>)</u><u>.</u></h3>

Assuming that X is a binomial random variable with n = 10 and p = 0.25, find the probability, P for each of the following values

seropon [69]

Answer: a) 0.0584

b) 0.2816

c) 0.1877

d) 0.1877117

Step-by-step explanation:

The binomial probability formula :-

$P(x)=^nC_xp^x(1-p)^{n-x}$ , where P(x) is the probability of getting success in x trials, n is total number of trials and p is probability of getting success in each trial.

Given : X is a binomial random variable with parameters :-

n = 10 and p = 0.25

$\text{a) P(x=5)}= ^{10}C_{5}(0.25)^5(0.75)^5\\\\=252(0.25)^5(0.75)^5\approx0.0584$

$\text{b) P(x=2)}= ^{10}C_{2}(0.25)^2(0.75)^8\\\\=45(0.25)^2(0.75)^8\approx0.2816$

$\text{c) P(x=1)}= ^{10}C_{1}(0.25)^1(0.75)^9\\\\=(10)(0.25)^1(0.75)^9\approx0.1877$

$\text{d) P(x=9)}= ^{10}C_{9}(0.25)^1(0.75)^9\\\\=(10)0.25)^1(0.75)^9\approx0.1877117$

SCORPION-xisa [38]

Step 1: move 64 to a left side, -13 - 64 = 7d

Step 2: -77 = 7d

Step 3: $\frac{-77}{7}$ = d

Step 4: d = -11
