A teacher instituted a new reading program at school. After 10 weeks in the program it was found that the mean reading speed of a random sample of 19 second grade students was 93.9 wpm. What might you conclude based on this result? Select the correct choice and ifll in the answer box in your choice below.

(Round to four decimal places as needed)

A). A mean reading rate of 93.9 wpm is unusual since the probability of obtaining a result of 93.9 wpm or more is . The new program is abundantly more effective than the old program.

B). A mean reading rate of 93.9 wpm is not unusual since the probability of obtaining a result of 93.9 wpm or more is. The new program is not abundantly more effective than the old program.

Picture of previous answers:

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

answer: i believe it’s 245.04

step-by-step explanation:

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.

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
