Answer:

Lets take the hypothesis

zα/2 

- zα/2 

Step-by-step explanation:

α/2 = 0.10/2 = 0.05 

z(0.05) = 3.92 

-z(0.05) = -3.92

Help on these 2 please!!

gladu [14]

Hope this helps
$7 \frac{1}{5} - 2 \frac{3}{5} = \frac{36}{5} - \frac{13}{5} = \frac{23}{5} = 4 \frac{3}{5}$

$8 \frac{2}{5} - 4 \frac{3}{5} = \frac{42}{5} - \frac{23}{5} = \frac{19}{5} = 3 \frac{4}{5}$
good luck

List the steps that should be used to solve the equation f(x) = g(x) by graphing when f(x) = (1/2)² - 3 and g(x) = 3x + 5?

jolli1 [7]

value of x is: $x=\frac{-31}{12}$

Step-by-step explanation:

We need to solve the equation f(x)=g(x)

where $f(x)=(\frac{1}{2})^2-3$

and $g(x) = 3x + 5$

Solving to find f(x)=g(x)

Putting values of f(x) and g(x)

$f(x)=g(x)\\(\frac{1}{2})^2-3=3x + 5\\\frac{1}{4}-3=3x + 5\\Subtarct\,\,5\,\,on\,\,both\,\,sides:\\\frac{1}{4}-3-5=3x + 5-5\\\frac{1}{4}-8=3x\\Taking\,\,LCm\,\,on\,\,left\,\,side\\\frac{1-8*4}{4}=3x\\\frac{-31}{4}=3x\\Divide\,\,both\,\,sides\,\,by\,\,3\\x=\frac{-31}{4*3}\\x=\frac{-31}{12}$

So, value of x is: $x=\frac{-31}{12}$

The graph will be a straight line x= -2.58 or x = -31/12
