idk , i get brainly answers !!!
Step-by-step explanation:
Answer:
780 students according to my calculations
Step-by-step explanation:
25 +(-4)*2 = 17
A value of 17 is -4 standard deviations from the mean.
Answer: The plane had traveled about 264 miles before turning back. The average speed was 230 mph
Step-by-step explanation: 230 - 10 = 220 speed outgoing
230+10 = 240 speed returning
Average speed (220+240)÷2= 460/2 =230 mph (needless to calculate!) Multiplied by total time 2.3 hours = 529 miles total distance.
Traveling the entire distance at 220mph would take about 2.4 hours. Traveling the entire distance at 240mph would take about 2.2 hours, a difference of .20 hours. Cut those times in half:
Traveling at 220mph for 1.2 hours would cover about 264 miles.
Traveling at 240mph for 1.1 hours would cover about 264 miles.
It adds up to 528 miles. The plane can't turn instantly, so figure the turn took the missing mile!
Of two angles and the included side of one triangle are congruent to the corresponding to the corresponding parts of another triangle hen the triangles are congruent. I really don't think there is additional information to prove if the triangles are congruent by using ASA.
Hopes this helps
