A psychologist researching new communication methods believes that is unusual for teenagers to send less than 275 texts each day. Assume that the daily number of texts sent by teenagers follows an unknown distribution with a mean of 300 texts and a standard deviation of 59 texts. The psychologist randomly selects 45 teenagers and records the number of texts they send on a particular day. Use a calculator to find the probability that the sample mean is less than 275 texts. Round your answer to three decimal places.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

addition

step-by-step explanation:

x = 12

y = 1

for the points!

i can not answer the question due to the fact that you spelled "carton" as "cartoon", a cartoon is something you watch on tv, a carton is a box that holds things. and also you've been waiting for this question for a while so why don't you get off your lazy a** and try to figure it out for yourself for once!
