What is the slope and y-intercept of (5x-8y=3) Need help asap plz! thank you!
Ksenya-84 [330]
You can isolate y and you know that the slope is the number in front of x (the one that multiplies it) You know that the y-intercept is the value of y when x=0, therefore you can find y by replacing x with 0 in the equation 1-equation 5x-8y=3 5x=3+8y 5x-3=8y (5x-3)/8=y y=(5/8)x -3/8 (Slope = 5/8) 2- y-intecept (x=0) y=(5/8)(0)-3/8 y=-3/8

Find the critical value z alpha/2 that corresponds to the given confidence level. ​81%
Karolina [17]

Critical values are basically cut-off values that indicate regions where the test statistic is unlikely to lie. The required critical value is 1.31.

<h3></h3><h3>What are critical Values?</h3>

Critical values are basically cut-off values that indicate regions where the test statistic is unlikely to lie; for example, if the null hypothesis is true, the critical value is surpassed with probability alpha.

The value of α can be written as,

α = 1 - 0.81 = 0.19

z_{\frac{\alpha}{2}} = \dfrac{0.19}{2}= 0.095

Now, using the z-table the value of z will be,

z = 1.31

Hence, the required critical value is 1.31.
