Step-by-step explanation:the first digit is your x and the second is your y so we go 6 back from the origin and 5 up from zero and we get -6,5. Also you always do x first

Distance formula: sqrt((x2-x1)^2 + (y2-y1)^2)

distance = sqrt((-1 -2)^2 + (-5-5)^2)
distance = sqrt(109)

Distance = 10.44

Answer:

correct option is D.0.0019

Step-by-step explanation:

given data

journal reports p = 34%

random sample n = 225

yielded = 97

solution

we get here first Sample proportion that is

Sample proportion p1 = $\frac{97}{225}$ ...............1

Sample proportion p1 = 0.4311

and here Null hypothesis is

H0 = p ≤ 0.34 ........................2

and

for Alternate hypothesis is

Ha = p > 0.34 ..........................3

so we get here z statistics that is express as

z = $\frac{p1- p}{\sqrt{\frac{p(1-p)}{n}}}$ ....................4

put here value and we get

$z = \frac{0.4311-0.34}{\sqrt{\frac{0.34(1-0.34)}{225}}}$

solve it we get

z = 2.88468

so here p-value for a test will be

P (z > 2.88468)

P = 1 - P (z < 2.88468)

P = 0.001957

so correct option is D.0.0019
