To tell isf a table is proportional, divide y by x,
if all sets are the same it is proportional.
First table:
3 / -3 = -1
2 / -4 = -2
-1 and -2 are not the same
Table 2:
1/-1 = -1
3/-3 = -1
5/-5 = -1
These are all the same.
Table 2 is correct.
Answer:
1.25 feet
Step-by-step explanation:
Put 6 where the variable is, then evaluate:
y = 80×(0.5)^6 = 80/64 = 1.25
The height after 6 bounces is 1.25 feet.
Answer:
Since 2.1387 is Greater Than 1.645;
we reject null hypothesis; we conclude that, the nickname is justified based on the data.
Step-by-step explanation:
Given the data in the question;
Null hypothesis H₀ : p = 0.262
Alternative Hypothesis H₁ : p > 0.262.
p" = 0.357
q = 1 - p = 1 - 0.262 = 0.738
n = 98
so;
z = (p" - p) / √(pq/n)
we substitute
z = (0.357 - 0.262) / √((0.262×0.738) / 98)
z = 0.095 / 0.04441869
z = 2.1387
at 5% CONFIDENCE INTERVAL
z-critical = 1.645
Since 2.1387 is Greater Than 1.645;
we reject null hypothesis; we conclude that, the nickname is justified based on the data.
