Answer:
I believe he can go on 30 rides.
Step-by-step explanation:
The equation would be 5 + .5x = 20
Because $5 to get in, plus $.50 per ride (x is number of rides you are solving for), and $20 is total amount you can spend.
So, .5x=15 so x=30
Answer:
zero probability, which means impossible
Step-by-step explanation:
there are no yellow marbles to select from
181 is the only palindrome that has digits that when multiplied together give you 8.
Hope that helps :)
Right triangles must follow the pythagorean theorem, so a^2+b^2=c^2.
Let's find a^2 and b^2 by squaring the first 2 side lengths.
(x^2-1)^2= x^4-2x^2+1
(2x)^2= 4x^2
Then add the two to find c^2
x^4+ 2x^2 +1= c^2
Root both sides
x^2+1=c
Since the side lengths can be plugged into the pythagorean theorem, the side lengths must represent a right triangle.
Hope this helps!
A) The mean of set 1 is 53,800, while the mean of set 2 is 38,600. The median of set 1 is 42,000, while the median of set 2 is 28,000.
B) The median is a more accurate estimate, because each set has 1 particularly large outlier which heavily skews the mean. In each set, the mean is actually higher than 4 out of the 5 data points, which is not very accurate in describing how much the typical car costs.
