A college wants to evaluate the performance of some of its officials. The institutional research office designs a survey to be implemented in Survey Monkey. The faculty are invited to participate in the survey through a mass email. Identify any true statements among the following. Group of answer choices

This is a random sample since all of the faculty have an opportunity to participate.

This is a volunteer sample.

The results of this survey would be unbiased.

The results of this survey would have unknown biases.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

the answer is  

a.

28 ft2

step-by-step explanation:

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
