A sample of 35 individuals at a shopping mall found that the mean number of visits to a restaurant per week was 2.92 with a standard deviation of 1.64 . Find a 95% confidence interval for the mean number of restaurant visits

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

too hard the other guy did it

step-by-step explanation:

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

160 cm

step-by-step explanation:

you have to add all the sides together
