A) The following data represent the high-temperature distribution for a summer month in a city for some of the last 130 years. Treat the data as a population. Complete parts (a) through (c). Temperature (F)- 50-59 60-69 70-79 80-89 90-99 100-109
Days 5 310 1444 1479 537 7

(a) Approximate the mean and standard deviation for temperature.
B. Draw a frequency histogram of the data to verify that the distribution is bell shaped.
While a histogram could be drawn by hand or by using technology, for this exercise, use technology.
The histogram to the right represents the data. Examine the frequency histogram of the data.

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
