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 altogether, did he make a reasonable inference? no, mr. yule’s sample is biased and too small to be representative of the population. yes, mr. yule’s 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.

it is x=-4

step-by-step explanation:

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n

-75 degrees, 9 minutes and 35.3 seconds w
