Answer:
The 99% confidence interval for the proportion of the population who are obese is (0.25, 0.282)
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
For this problem, we have that:
99% confidence level
So , z is the value of Z that has a pvalue of , so .
The lower limit of this interval is:
The upper limit of this interval is:
The 99% confidence interval for the proportion of the population who are obese is (0.25, 0.282)
The solution to the system is where the lines intercept. If you look at the graph, you see that the lines intercept at (1,2). So, the answer would be C.
Answer:
25/40=13/20
Step-by-step explanation:
just add 9 and 17 which is 26. so it's 26/40. simplify so it's 13/20
Answer:
<h2>$22.25</h2>
Step-by-step explanation:
Step one:
given data
we are told that the cost of one ride is $2.25
the entry fee= $6.5
the linear function for the situation is represented by the equation of line
y=mx+c
Step two:
let x be the number of ride
given that x=7
substituting we have
y=2.25(7)+6.5
y=15.75+6.5
y=22.25
In all Lupe we have to pay $22.25
Distributive property is an algebra property which is used to multiply a single term and two or more terms inside a set of parentheses. Ex. 6 x 4= 6 x (2+2)
= ( 6 x 2)+(6 x 2)
= 12 + 12
= 24
Commutative property is the one that mentions to move stuff around. Ex. 3 x 2= 6 -----> 2 x 3= 6
Associative property states that you can add or multiply anyway of how the numbers are grouped, By "grouped" I mean how you use parentheses. In other words, if you are adding or multiplying it doesn't matter where you put the parentheses. Ex.(8 x 3) x 2 = 8 (3 x 2 )
24 x 2 8 x 6
48 = 48
