Answer:

$p = 56\% = 0.56 \\ n = 5 \\ q = 1 - p = 0.44 \\ P(X = x) = {n \choose x} {p}^{x} {q}^{(n - x) } \\ P(X < 2) = P(X = 0) + P(X = 1) \\ {5 \choose 0} {0.56}^{0} {0.44}^{(5 - 0) } + {5 \choose 1} {0.56}^{1} {0.44}^{(5 - 1) }$

Answer:

y = - cos ( $\frac{3}{4}$ x + $\frac{\pi }{4}$ )

Step-by-step explanation:

y = A cos ( Bx + C) + D

Vertical shift D = 0

A = - 1

Compression / Stretching B

Period of given function is $\frac{8\pi }{3}$

Period of cos x is 2π

$\frac{8\pi }{3}$ = $\frac{2\pi }{B}$ ⇒ B = $\frac{3}{4}$

Horizontal shift is C ÷ B

Horizontal shift of given function is $\frac{\pi }{3}$

$\frac{\pi }{3}$ = C ÷ $\frac{3}{4}$ ⇒ C = $\frac{\pi }{4}$

So, the equation of given function is

y = - cos (  $\frac{3}{4}$  x +  $\frac{\pi }{4}$  )

8(7 + 23) = 8(7) + 8(?)

Answer: 23

When using multiplication with brackets, you multiply the number by all the numbers within the bracket before adding them together.

Therefore when it is 8(7 + 23) it basically means: 8(7) + 8(23)
