Find z such that 4.8% of the standard normal curve lies to the left of z. (Round your answer to two decimal places)

lukranit [14]

Answer:

The correct answer will be "-1.66".

Step-by-step explanation:

Let z₀ be,

$P(z$

$=0.048$

⇒ $\Phi (z_0)=0.048$

Now,

⇒ $\Phi (-1.6646)=0.048$

$z_0=-1.6646$

$\simeq -1.66$

Thus the above is the right answer.

Simplify the expression with using scientific notation (4 times 10 8)2

kifflom [539]

The scientific notation:

$a\cdot10^n\\\\1\leq a < 10;\ n\in\mathbb{Z}$

$(4\cdot10^8)^2=4^2(10^8)^2=16\cdot10^{8\cdot2}=16\cdot10^{16}\\\\=1.6\cdot10\cdot10^{16}=1.6\cdot10^{17}$

Used:

$(a\cdot b)^n=a^n\cdot b^n\\\\(a^n)^m=a^{n\cdot m}\\\\a^n\cdot a=a^{n+1}$

Answer: (4 × 10⁸)² = 1.6 × 10¹⁷
