Answer: 3, -4

Step-by-step explanation:

There really isn't a step by step, but here...

If you reflect off the y-axis, the one going vertical, the G lands on the same numbers, but with different integers, leaving -4 the same and changing what's in the x-axis, giving you 3.

If you have the equation of different situations into y = mx + b, What do m and b represent?

alexandr1967 [171]

Answer:

C. m represents the slope and b represents the y-intercept.

Step-by-step explanation:

The equation of straight line is usually expressed as:

y = mx + b

Where y is the vertical axis component

x is the horizontal axis component

m is the slope

b is the y-intercept

At the y-intercept, x = 0

Also, the slope is the rise divided by the run.

Construct the confidence interval for the population standard deviation for the given values. Round your answers to one decimal

Alex777 [14]

Answer:

The correct answer is " $2.633< \sigma < 4.480$ ".

Step-by-step explanation:

Given:

n = 21

s = 3.3

c = 0.9

now,

$df = n-1$

$=20$

⇒ $x^2_{\frac{\alpha}{2}, n-1 }$ = $x^2_{\frac{0.9}{2}, 21-1 }$

= $31.410$

⇒ $x^2_{1-\frac{\alpha}{2}, n-1 }$ = $10.851$

hence,

The 90% Confidence interval will be:

= $\sqrt{\frac{(n-1)s^2}{x^2_{\frac{\alpha}{2}, n-1 }} } < \sigma < \sqrt{\frac{(n-1)s^2}{x^2_{1-\frac{\alpha}{2}, n-1 }}$

= $\sqrt{\frac{(21-1)3.3^2}{31.410} } < \sigma < \sqrt{\frac{(21.1)3.3^2}{10.851} }$

= $\sqrt{\frac{20\times 3.3^2}{31.410} } < \sigma < \sqrt{\frac{20\times 3.3^2}{10.851} }$

= $2.633< \sigma < 4.480$
