Leewood Middle School is considering a uniform policy, and the principal has
asked for students' opinions about the
colors for the uniform shirts. Jennifer
and Josef conducted surveys about the
possible shirt colors. Their methods
and results are described below.
Jennifer · Sampling method: Gave
each student in her history class a
survey to complete anonymously at
home and return the following day. She
received 50% of the surveys the next
day. · Results: 85% prefer blue shirts.
Josef · Sampling method: Wrote all
students' names on slips of paper.
Gave survey to the 50 students whose
names were chosen at random.
Results: 60% prefer blue shirts.
Explain whose sampling method will
provide results most representative of
all students at Leewood Middle School
and why.
Provide your own example of another
method that would represent all
studente at Lowood Middle School

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
