The value of the cumulative standardized normal distribution at z is 0.8770. what is the value of z?

Vinvika [58]

<span>The value of z is 0.8770. This answer was derived from information in the question, which states that the value of z is 0.8770. Granted, I don't understand what is meant by "cumulative standardized normal distribution." I only passed statistics because the professor felt sorry for me.</span>

Write the equation of a line that is parallel to 4x-2y=3 and is passing through the point (2,1)

Temka [501]

Answer:

y= 2x -3

Step-by-step explanation:

Let's rewrite the given equation into the form of y=mx+c, so that we can find the gradient of the line. In this form, m (coefficient of x) is the gradient.

4x -2y= 3

2y= 4x -3

<em>Divide</em><em> </em><em>by</em><em> </em><em>2</em><em> </em><em>throughout</em><em>:</em>

$y = 2x - 1 \frac{1}{2}$

Thus the gradient is 2.

Parallel lines have the same gradient thus the line would also have a gradient of 2.

Substitute m=2 into the equation:

y= 2x +c

To find the value of c, substitute a pair of coordinates.

When x=2, y=1,

1= 2(2) +c

1= 4 +c

c= 1 -4

c= -3

Thus, the equation of the line is y= 2x -3.

What is x/9 = 9/27 help plz

Irina18 [472]

<h3><u>QUES</u><u>TION</u><u>:</u><u> </u></h3>

what is x/9 = 9/27 help plz

<h3><u>ANSWER</u><u> </u><u>AND</u><u> </u><u>SOLU</u><u>TION</u><u>:</u><u> </u></h3>

SOLVING FOR X

<u>Reduce</u><u> </u><u>first</u><u> </u><u>the</u><u> </u><u>fraction</u><u> </u><u>with</u><u> </u><u>9</u>

$\large \sf = \dfrac{x}{9} = \dfrac{ \cancel9}{ \cancel{27}}$

<u> $\large \sf = \dfrac{x}{9} = \dfrac{1}{3}$ </u>

<u>Now</u><u> </u><u>simpli</u><u>fy</u><u> </u><u>using</u><u> </u><u>cross-multiply</u>

<u> $\large \sf = \dfrac{3x}{9} = 1$ </u>

<u> $\large \sf = 3x = 1 \times 9$ </u>

<u> $\large \sf = 3x = 9$ </u>

<u>Lastly</u><u> </u><u>divide</u><u> </u><u>both</u><u> </u><u>sides</u>

<u> $\large \sf = 3x \div 3 = 9 \div 3$ </u>

<u> $\large \sf = x = 9 \div 3$ </u>

<u> $\large \sf = x = 3$ </u>

<h3><u>FINAL</u><u> </u><u>ANSWER</u><u>:</u></h3>

$\huge \orange{ \underline{ \boxed{ \sf{x = 3}}}}$

HOPE THIS HELP YOU! HAVE A NICE DAY!
