A random sample of 9th grade students was asked if they prefer their math problems using a pencil or a pen. Of the 250 surveyed, 100 preferred pencil and 150 preferred pen . Using the results of this survey, construct a 95% confidence interval for the proportion of 9th grade students that prefer their math problems using a pen. A school newspaper reported , " Over half of ninth graders prefer to use pen on their math assignments ." Is this statement supported by your confidence interval ?

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.

45.36 feet per second.

step-by-step explanation:

to find the most accurate determination for the number of feet per second tyrone traveled on his way to work let us convert miles to feet and minutes to seconds.

1 mile = 5280 feet.

1 minute = 60 seconds.

now we will divide 158400 by 3492 to find the most accurate determination for the number of feet per second tyrone traveled on his way to work.

therefore, tyrone traveled on his way to work at the rate of 45.36 feet per second.
