The distribution of the number of hours people spend at work per day is unimodal and symmetric with a mean of 8 hours and a stan

Wewaii [24]

Answer: 95% of all people work between 7 hours and 9 hours per day and It is true.

Step-by-step explanation:

Since we have given that

Mean = 8 hours

Standard deviation = 0.5 hours

According to Empirical Rule,

at 95% confidence, it lies within 2 standard deviations from the mean

so, lower value is given by

$mean-2\times sd\\\\=8-2\times 0.5\\\\\=8-1\\\\=7\ hours$

upper value is given by

$mean+2\times s.d\\\\=8+2\times 0.5\\\\=8+1\\\\=9\ hours$

Hence, 95% of all people work between 7 hours and 9 hours per day.

Therefore , it is true.

Which of the binomials below is a factor of this trinomial x^2+4x-60

trasher [3.6K]

Suppose x-6 is listed as a possible answer. That is zero if x = 6. So put x=6 into the original x^2 + 4x - 60 to get 6^2 + 4*6 - 60 = 36 + 24 -60 = 0. hence x-6 is a factor.

Answer (x-6)

on this hand :x-5 is not a factor, because plugging x=5 into does not work.
