Answer:
The proportion of scores reported as 1600 is 0.0032
Step-by-step explanation:
Let X be the score for 1 random person in SAT combining maths and reading. X has distribution approximately N(μ = 1011,σ = 216).
In order to make computations, we standarize X to obtain a random variable W with distribution approximately N(0,1)
The values of the cummulative distribution function of the standard Normal random variable, lets denote it are tabulated, you can find those values in the attached file. Now, we are ready to compute the probability of X being bigger than 1600
Hence, the proportion of scores reported as 1600 is 0.0032.
Check the picture below.
notice, both angles are lying on a flat-line, surely you'd know what "x" is then.
Răspuns:
318 de participanți
Explicație pas cu pas:
Dat fiind:
Număr în parc = 106
Numărul din parc reprezintă 1/3 din numărul elevilor care participă la activitatea de curățenie.
Pentru a obține numărul total de studenți care participă la activitate; fie numărul total = x
Prin urmare;
1/3 din x = 106
x / 3 = 106
Înmulțiți ambele părți cu 3
x = 318
Prin urmare, numărul total de studenți implicați în activitatea de curățenie = 318 stuaen
