Find the area under the standard normal curve to the left of

JulijaS [17]

A. z = 0.74
The z-score of 0.74 translates to a percentile of 0.77035. Hence, the area under the standard normal curve to the left of z-score 0.74 is ~0.77.

b. z = -2.16
This z-score translates to a percentile of 0.015386 which is also the numerical value of the area under the curve to the left of the z-score

c. z = 1.02
The percentile equivalent of the z-score above is 0.846. The area is also 0.846.

d. z = -0.15
The percentile equivalent and the area is equal to 0.44.

Step-by-step explanation:

6. The fraction can be written as;

$\frac{x^2}{2y} /\frac{y^2}{4} \\\\\frac{x^2}{2y} *\frac{4}{y^2} \\\\$

Divide 4 by 2

= $\frac{2x^2}{y^3}$

The fraction can be written as;

$\frac{b^2}{6} /\frac{b}{a}$

introduce product sign as

$\frac{b^2}{6} *\frac{a}{b} \\\\=b*a/6\\=\frac{ab}{6}$

The fraction can be written as;

$\frac{x}{y} /\frac{yx}{2}$

Introduce product sign

$\frac{x}{y} *\frac{2}{yx} \\\\=\frac{2}{y^2}$

The fraction can be written as;

$\frac{x}{y^2} /\frac{x}{y} \\\\\\=\frac{x}{y^2} *\frac{y}{x} \\\\\\=\frac{1}{y}$

10.

The fraction is simplified to;

$\frac{x}{3y} /\frac{9}{x} \\\\\\\frac{x}{3y} *\frac{x}{9} =\frac{x^2}{27y}$

Find the sum. Express your answer in simplest form. 9a^2-5/b^2+2 + -2a^2+4/b^2+2

KonstantinChe [14]

Answer:

Step-by-step explanation:

$\frac{9a^{2}-5}{b^{2}+2}+\frac{-2a^{2}+4}{b^{2}+2}=\frac{9a^{2}-5-2a^{2}+4}{b^{2}+2}\\\\=\frac{9a^{2}-2a^{2}-5+2}{b^{2}+2}\\\\=\frac{7a^{2}-3}{b^{2}+2}$
