Which of the following are true statements? Select all that apply.

Savatey [412]

You are probably expected to choose ...
• All integers are rational numbers.
• Terminating decimals are rational numbers.

However, the premise of ...
• 0.278254….. is a terminating decimal, therefore it is a rational number.
is False, so the rules of logic allow any conclusion—meaning the implication is True. (As it happens, a repeating decimal is, in fact, a rational number.) So, this, too, is a true statement.

Please help me with this geometry question !!!

Inessa05 [86]

Answer:

see explanation

Step-by-step explanation:

Under a counterclockwise rotation about the origin of 90°

a point (x, y ) → (- y, x ), thus

P(1, - 1 ) → P'(1, 1 )

Q(3, - 2 ) → Q'(2, 3 )

R(3, - 4 ) → R'(4, 3 )

Compute the following binomial probabilities directly from the formula for b(x; n, p). (Round your answers to three decimal plac

yuradex [85]

<h2>Answer with explanation:</h2>

We know that the binomial theorem for finding the probability of x success out of a total of n experiments is given by:

$b(x;n;p)=n_C_x\cdot p^x\cdot (1-p)^{n-x}$

(a)

b(5; 8, 0.25)

is given by:

$8_C_5\cdot (0.25)^5\cdot (1-0.25)^{8-5}\\\\=8_C_5\cdot (0.25)^5\cdot (0.75)^3\\\\=56\cdot (0.25)^5\cdot (0.75)^3\\\\=0.023$

Hence, the answer is: 0.023

(b)

b(6; 8, 0.65)

i.e. it is calculated by:

$=8_C_6\cdot (0.65)^6\cdot (1-0.65)^{8-6}\\\\=8_C_6\cdot (0.65)^6\cdot (0.35)^2\\\\=0.259$

Hence, the answer is: 0.259

(c)

P(3 ≤ X ≤ 5) when n = 7 and p = 0.55

$P(3\leq x\leq 5)=P(X=3)+P(X=4)+P(X=5)$

Now,

$P(X=3)=7_C_3\cdot (0.55)^3\cdot (1-0.55)^{7-3}\\\\P(X=3)=7_C_3\cdot (0.55)^3\cdot (0.45)^{4}\\\\P(X=3)=0.239$

$P(X=4)=7_C_4\cdot (0.55)^4\cdot (1-0.55)^{7-4}\\\\P(X=4)=7_C_4\cdot (0.55)^4\cdot (0.45)^{3}\\\\P(X=4)=0.292$

$P(X=5)=7_C_5\cdot (0.55)^5\cdot (1-0.55)^{7-5}\\\\P(X=3)=7_C_5\cdot (0.55)^5\cdot (0.45)^{2}\\\\P(X=3)=0.214$

Hence,

$P(3\leq x\leq 5)=0.745$

(d)

P(1 ≤ X) when n = 9 and p = 0.1 .613

$P(1\leq X)=1-P(X=0)$

Also,

$P(X=0)=9_C_0\cdot (0.1)^{0}\cdot (1-0.1)^{9-0}\\\\i.e.\\\\P(X=0)=1\cdot 1\cdot (0.9)^9\\\\P(X=0)=0.387$

i.e.

$P(1\leq X)=1-0.387$

Hence, we get:

$P(1\leq X)=0.613$
