Answer:
Fourth chice, 3/5
Step-by-step explanation:
Add all the numbers together, 12 + 3 + 5 = 20
There's 12 green cubes out of the 20 cubes so it's 12/20 which is 3/5
Answer:
Less than 100. Z=83
Step-by-step explanation:
The mean is the average found by adding the sum of the data points and dividing by the number of them. Here there are 3 cars whose speeds are 101, 116, and Z or unknown. The mean of them is 100. Solve for Z.
100 =(101+116+Z)/3
300=217+Z
83=Z
Please see the picture below
Side = 8 - u / 2
We can solve this pretty easily using a proportion where x equals the number of cloudy days in the year:
2/5 = x/365
Now cross multiply:
730 = 5x
And finally divide both aides by five:
146 = x
So 146 days of the year were cloudy.

Answer:
Probably A, or 1
Step-by-step explanation:
You see, a square root function actually looks like a sideways parabola, just missing one side because of the domain of a square root. Now, the reason I can tell them apart is because our vertex is below the y-axis, and the only equation that has a negative y-intercept is the first one, or A.
Hope this helps!
