diegueno is selling ticket for tge dance. Tickets purchased in advanced cost $4 while tickets at the door cost $6. If 325 ticket
s are sold and $1430 is collected, how many tickets were sold?
1 answer:
Answer:
The numbers of tickets in advanced sold was 260 and the numbers of tickets at the door sold was 65
Step-by-step explanation:
Let
x ---> the numbers of tickets in advanced sold
y ---> the numbers of tickets at the door sold
we know that
325 tickets are sold
so
----> equation A
$1430 is collected
so
----> equation B
Solve the system of equations by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (260,65)
see the attached figure
therefore
The numbers of tickets in advanced sold was 260 and the numbers of tickets at the door sold was 65

Answer:
3.84% probability that it has a low birth weight
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
If we randomly select a baby, what is the probability that it has a low birth weight?
This is the pvalue of Z when X = 2500. So
has a pvalue of 0.0384
3.84% probability that it has a low birth weight
Answer:
Step-by-step explanation:
We can simplify the expression under the root first.
Remember to use
Thus, we have:
We know 4th root can be written as "to the power 1/4th". Then we can use the property
