Answer:
first term (a)= 2
second term (b) = -8
common ratio (r) = -8/2 = -4
15th term = ar^ (n-1)
= 2* (-4)^ 14 =536870912
Step-by-step explanation:
Answer:
2.5 meters per second
Step-by-step explanation:
75/30 = 2.5
I'd choose 25 because the person who wrote the answers probably forgot to add decimal points
Answer:
Landing on a 1 or 2.
25% means 0.25, or 2/8 chance of winning. The spinner has 2 out of 8 as 1 or 2.
What you would do is -10+5=-5 then you add 4+7= 11 then you mutiply them answers together 11*-5=-55 hope this helps you
Answer:
2.88
Step-by-step explanation:
Data provided in the question
= Population standard deviation = 7 miles per hour
Random sample = n = 32 vehicles
Sample mean = 
= 64 miles per hour
98% confidence level
Now based on the above information, the alpha is
= 1 - confidence level
= 1 - 0.98
= 0.02
For 
= 0.01
= 2.326
Now the margin of error is
= 2.88
hence, the margin of error is 2.88
