At Brighton Middle School, Mr. Yule asked 50 randomly selected students from each grade level about their favorite subject,
and 12 chose science He used this data to draw the inference that about 25% of middle school students will indicate science
is their favorite subject. If there are 200 students all together, did he make a reasonable inference?
No, Mr. Yule's sample is biased and too small to be representative of the population
Yes, Mr. YUNs sample is small and biased, so it is representative of the population
No, Mr. Yule's percentage is too large. He should have used 6%
Yes, Mr. Yule's sample is random and representative of the population

this might get deleted, sorry. it has to be an actual question. if you really wanted to give someone free points, ask a question like "why does the sky look blue, and the sun is yellow to our eyes? "

step-by-step explanation:

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.
