Answer:
No mode.
Step-by-step explanation:
No mode.
None of the numbers repeat and since the mode is the most frequent number there isn't one.
Answer:
d. 20
Step-by-step explanation:
Standard deviation is 4.5
Margin error for the problem is 2 hours
Probability 95%, that means that the siginficance level α is 1 – p
α = 1 – 0.95 = 0.05
margin of error (ME) can be defined as follows
ME = Z(α/2) * standard deviation/ √n
Where n is the sample size
Z(0.05/2) = Z(0.025)
Using a z table Z = 1.96
Now, replacing in the equation and find n
2 = 1.96 * 4.5/ √n
2 = 8.82/√n
√n = 8.82/2
√n = 4.41
n = 4.41^2
n = 19.44 ≈ 20
I believe the answer is 35 degrees, or A.
X=14
3 times 14 is 42-13 is 29
this equation is not funcion.
Step-by-step explanation:
if u make a graph and u aline them with dots 2 or more dots will cross each other witch makes it not function:)
