Hello there!
Your question states: Levi purchased a total of 50 ride and game tickets and the amusement park and spent $29. if ride tickets cost 75 cents each and game tickets cost 50 cents each, how many ride tickets did he purchase?
x = rides
y = games
<span>x + y= 50
<span>0.75x + 0.50y = 29
To solve this system of equations, we can graph (attached below).
As we can see, the answer is (16, 34)
This means that he purchased 16 ride tickets and 34 game tickets.
Hope I helped!

Answer:
26.11% of women in the United States will wear a size 6 or smaller
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:
In the United States, a woman's shoe size of 6 fits feet that are 22.4 centimeters long. What percentage of women in the United States will wear a size 6 or smaller?
This is the pvalue of Z when X = 22.4. So
has a pvalue of 0.2611
26.11% of women in the United States will wear a size 6 or smaller
