2/7 represents poop proportional poop is when you cut the poop in the middle
Answer:
D. 4
Step-by-step explanation:
Percent of drivers who wear seat belts = 68
Percent of drivers who do not wear seat belts = 100 - 68 = 32
Now, we know that for every 100 pull overs, 32 drivers will not be wearing belt.
32 drivers without seat-belt = 100 pullovers
1 driver without seat-belt = 100/32 pullovers
1 driver without seat-belt = 3.125 pullovers (4 pullovers)
So, a police officer should expect 4 pullovers until she finds a driver not wearing a seat-belt.
Answer:
<em>C. Omitted variable bias
</em>
Step-by-step explanation:
In mathematics and statistics, omitted-variable bias (OVB) happens if one or more important variables is left out by a statistical model.
The bias results in the equation being related to the expected effects of the included variables by the influence of the excluded variables.
I'm guessing that you meant to type 4(x - 3). If that's the case, then you can solve this using the Distributive Property.
4(x - 3) Multiply the number on the outside of the parentheses by both of the numbers on the inside.
(4 · x) - (4 · 3)
(4x) - (12) Now, simplify by taking out the parentheses.
4x - 12
Answer:
x = 14
Step-by-step explanation:
2x+4 - 12 = 20
2x - 8 = 20
2x = 28
x = 14
