Answer:
she was born in 1932
Step-by-step explanation:
2007-75=1932
16.5 / 1 = x / 24.....16 1/2(or 16.5) turns to 1 inch = x turns to 24 inches
cross multiply
x = 16.5 * 24
x = 396 turns <==
The common denominator is 3 because
example: 3x4= 12 and 3x3= 9
Answer:
liar is 10
Step-by-step explanation:
Answer:
(a) The probability distribution is valid.
(b) The histogram is attached below.
(c) The mean is 33.47.
Step-by-step explanation:
(a)
A probability distribution is valid if:
- P (X = x) ≥ 0 for all values of <em>x</em>.
- ∑ P (X = x) = 1
From the probability distribution table it can be seen that the probability for all <em>x</em> is greater than 0.
Compute the sum of all probabilities as follow:
Thus, the probability distribution is valid.
(b)
The histogram is attached below.
(c)
The formula of mean of a discrete probability distribution is:
Compute the mean as follows:
Thus, the mean is 33.47.
