it's only a terminating decimal if you end up with a remainder of 0.
Answer:
i)
ii)
And replacing we got:
iii)
Step-by-step explanation:
Let X the random variable of interest "number of inhabitants of a community favour a political party', on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
Part i
We want this probability:
Part ii
We want this probability:
And we can use the complement rule and we have:
And if we find the individual probabilites we got:
And replacing we got:
Part iii
We want this probability:
And replacing we got:
Answer:
-5 = -3(5) + 10
Step-by-step explanation:
y = mx + b
They have given you the x and y values and the slope, m
y = -3x + b
sub the ordered pair
-5 = -3(5) + b
-5 = -15 + b
add 15
10 = b
-5 = -3(5) + 10
Answer:
458
Step-by-step explanation:
Margin of error = critical value × standard error
At 99% confidence, the critical value is z = 2.576.
The standard error is σ/√n = 5.4/√n.
Given the desired margin of error is 0.65:
0.65 = 2.576 × 5.4/√n
n = 458
