What would - 1/3*y-6=11 be when solving for y?

Find the value of x in the rectangle ABCD.

attashe74 [19]

Answer:

52°

Step-by-step explanation:

here's your solution

=> we know that the measure of angle of rectangle is 90°

=> 38° + X = 90°

=> X = 90° - 38°

=> X = 52°

$\frac{1}{4} \times 100 = 25 \: \: percent \\$

$\frac{25}{100} \times 3 = \frac{75}{100} = 0.75 \\$

Thus :

1 / 4 % of 3 is 0.75 .

Answer:

z = -0.4.

Step-by-step explanation:

Here's the formula for finding the z-score (a.k.a. standardized normal variable) of one measurement $x$ of a normal random variable $X \sim N(\mu,\; \sigma^{2})$ :

$\displaystyle z = \frac{x-\mu}{\sigma}$ ,

where

$z$ is the z-score of this measurement,
$x$ is the value of this measurement,
$\mu$ is the mean of the random normal variable, and
$\sigma$ is the standard deviation (the square root of variance) of the random normal variable.

Let the length of a trout in this lake be $X$ inches.

$X \sim N(30, \; 4.5^{2})$ .

$\mu = 30$ , and
$\sigma = 4.5$ .

For this measurement, $x = 28.2$ . Apply the formula to get the z-score:

$\displaystyle z = \frac{x - \mu}{\sigma} = \frac{28.2 - 30}{4.5} = -0.4$ .

Given f(x) = 7x^9, find f^-1 (x). Then state whether f^-1 (x) is a function

Olin [163]

A though without graphing software it would appear to be C

Step-by-step explanation:
The inverse of a function is the function reflected across the line y=x. This results in the coordinate points (x,y) of the function becoming (y,x) for the inverse function. Algebraically to find the inverse, switch the x and y locations and solve for y.
y = 7x^9
x = 7y^9
x/7 = y^9
(9)√(x/7) = y
This is a ninth root of (x/7) also written in exponents as y = (x/7)^(1/9).
This is a function. While it appears not to be a function because the middle portion over the origin appears vertical, it is a function because the middle portion over the origin is changing and graphing software shows it has no input with more than one output. Without graphing software you would rule it is not a function.
