Consider the accompanying data on flexural strength (mpa) for concrete beams of a certain type.

11.8 7.7 6.5 6.8 9.7 6.8 7.3

7.9 9.7 8.7 8.1 8.5 6.3 7.0

7.3 7.4 5.3 9.0 8.1 11.3 6.3

7.2 7.7 7.8 11.6 10.7 7.0

a) calculate a point estimate of the mean value of strength for the conceptual population of all beams manufactured in this fashion. [hint: ? xi = 219.5.] (round your answer to three decimal places.)

//blooming serenity//

beautiful in the morning

mysterious at night

wonderous nature souring

with all it's mystical might

the flower that blooms

to the fox that looms

nocturnal creatures

with various features

a blooming flower soon in sight

as a new little hatchling fears to take flight  

afraid to leave it's calming nest,

but dear little bird, mother knows best

as sure as there are stars in the sky,

life is not about who, where what, when or why-

it's the journey that follows

adventures we swallow

of   nature's deep wonders,

natural disasters and storm's thunders.

blooming serenity

life and nature, truly is heavenly.

step-by-step explanation:

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
