Answer:

z would be your radius

Step-by-step explanation:

Equation: (x - h)² + (y - k)² = r²

Simply take √r² to find <em>r</em>, your radius.

Calculate the slope of a line that passes through the points (-4,7) and (-1,3)

zmey [24]

Answer:

The answer is

$- \frac{4}{3} \\$

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

$m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-4,7) and (-1,3)

We have

$m = \frac{3 - 7}{ - 1 - - 4} = \frac{ - 4}{ - 1 + 4} = - \frac{4}{3} \\$

We have the final answer as

$- \frac{4}{3} \\$

Hope this helps you

4. The value of y varies directly with x. When y = 275, x = -22 What is y when x = 17.5?

Helga [31]

y = x

275 = -22

y = 17.5

y = (17.5*275)/-22

y = -179.0

Let μ denote the true average reaction time to a certain stimulus. For a z test of H0: μ = 5 versus Ha: μ > 5, determine the

hoa [83]

Answer:

0.0778, 0.1789,0.0250

Step-by-step explanation:

Given that μ denote the true average reaction time to a certain stimulus. For a z test of H0: μ = 5 versus Ha: μ > 5

(Right tailed test)

To find p value:

a) Z = 1.42: p = 0.077804

=0.0779

b) z = 0.92

p value = 0.1789

c)z= 1.96

p value = 0.0250
