Answer:
1.86
Step-by-step explanation:
Given the following :
X : - - - - 0 - - - - 1 - - - - 2 - - - - - 3 - - - - 4
P(x) - 0.37 - - 0.28 - - 0.22 - - 0.22 - - 0.12
The mean of the distribution can be calculated by evaluated by determining the expected value of the distribution given that the data above is a discrete random variable. The mean value can be deduced multiplying each possible outcome by the probability of it's occurrence.
Summation of [P(x) * X] :
(0.37 * 0) + (0.28 * 1) + (0.22 * 2) + (0.22 * 3) + (0.12 * 4)
= 0 + 0.28 + 0.44 + 0.66 + 0.48
= 1.86
Answer:
$450>$235
Step-by-step explanation:
This is because, when 235 is subtracted from 450 there is a great difference thats why $450 is greater than $235
Varies directly basically means a multiple of
y = kx
where "k" is the constant of variation. You must solve for this first using the given information.
8 = 42k
8/42 = k
0.19= k
Equation: y = 0.19x
when x = 126
y = 0.19(126)
y = 24
50/5 is 10 so the rate of change is 10
Answer: 0.000527
Step-by-step explanation:
Given: in standard form.
The standard form are also known as scientific notation.
Scientific notation is a way to write a very large or a very small number in the product of a decimal form of number [generally between 1 and 10] and powers of ten.
Since the power of 10 is negative, then it must be smaller than 1.
We can write the given number in decimal form as
