Answer:
The probability mass of X is 0.03
Step-by-step explanation:
If we set the winning requirement of your heads and my tails then the occurring possibility of both is 1/2 or 0.5.
Hence let us make a graph and use the figures to calculate the all the probabilities of you getting a heads.
Where X represents the number of dollars won during the flip of the coin, probability of heads represent the chances of occurrence of the value and of winning the dollars.
The probability of winning start to drop as the winning amount increases.
X 0 1 2 3 4 5
Probability of Heads 0 0.50 0.25 0.13 0.06 0.03
Answer:
a
The 90% confidence interval is 
b
Confidence interval for the population men between <u>$52561.13</u> up to <u>$57540.8</u>
Step-by-step explanation:
From the question we are told that
The sample size is 
The sample mean is 
The standard deviation is 
Given that the confidence level is 90% then the level of confidence is mathematically represented as



Next we obtain the critical value of
from the normal distribution table the values is

Generally the margin of error is mathematically represented as

substituting values


The 90% confidence interval is mathematically evaluated as

substituting values


Answer:
43470
Step-by-step explanation:
purchased of home =$85000
improvement of home =1530=
85000
+1530
=86530
the valued of home =130000=
130000
-86530=
43470
<span>4(2p+4q+6)
You need to multiply 4 by each variable in the parentheses.
(4*2p) + (4*4q) + (4*6)
8p + 16q + 24 is the answer.</span>
