Answer:
Y = 0
Step-by-step explanation:
Y = -1/2 x²

Solve the equation for y
Y = 0
Answer:
C) square root of 7
Step-by-step explanation:
Irrational numbers are numbers which have endless decimals that do not repeat. You can't guess what the next decimal would be. For example, pi.
Both -2.13 and 0.3 have decimals, but they end at the first or second place.
Step-by-step explanation:
A ratio is a relation between two numbers.
*A ratio determines how many times 20 contains/values 8.
<u>A ratio representing the width to the length is: </u>
8:20.
8 represents the width, 20 represents the length.
To simplify a ratio, you must divide each side by the same number.
<u>S</u><u>i</u><u>mplified </u><u>ratios</u><u> </u><u>are</u><u>:</u>
4:10 (Divide by 2)
2:5 (Divide by 4)
1:2.5 (Divide by 8)
The ratio is detailing that the length is 2.5 times larger than the width.
<u>Your answers are;</u>
8:20
4:10
2:5
1:2.5
Using it's concept, it is found the standard deviation of $10 means that most students spent within $10 of the mean of $60 on the slot machines.
<h3>What is the standard deviation of a data-set?</h3>
- The standard deviation is given by the square root of the sum of the differences squared of each observation and the mean, divided by the one less than the number of values.
- It represents by around how much the distribution varies around the mean.
Hence, in this problem, the standard deviation of $10 means that most students spent within $10 of the mean of $60 on the slot machines.
