Some have argued that throwing darts at the stock pages to decide which companies to invest in could be a successful stock-picking strategy. suppose a researcher decides to test this theory and randomly chooses 100100 companies to invest in. after 1 year, 5353 of the companies were considered winners; that is, they outperformed other companies in the same investment class. to assess whether the dart-picking strategy resulted in a majority of winners, the researcher tested upper h 0h0: pequals=0.5 versus upper h 1h1: greater than> 0.5 and obtained a p-value of 0.27430.2743. explain what this p-value means and write a conclusion for the researcher. (assume alphaα is 0.1 or less.)

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%

happy to

pls mark as brainliest

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

good luck on ur quiz test or homework. have a good day : )
