Answer:
-17
Step-by-step explanation:
"the opposite of 17 is -17. You can figure this out by finding the negative version of 17, or the additive inverse of 17. Opposites, when added together, create a sum of 0."
Answer:
The price before tax was $110
Step-by-step explanation:
Here the price paid totals $129.25, including b (the pre-tax price) an 17.5% of b: b + 0.175b = $129.25. Combining the b terms, we get:
1.175b = $129.25. Solving for b by dividing both sides by 1.175, we get
b = $110. The price before tax was $110.
Subtract 1:
x/4=2
multiply by 4:
x=8 which is the answer
Answer: x=15 and y=6
Step-by-step explanation:
2y+49 + 8y+71 = 180 (Then solve)
5x+44 + 3x+16 = 180 (Then solve)
Answer:
Choice B) experimental probability is larger
Step-by-step explanation:
There are 3 odd numbers (1,3,5) out of 6 total (1,2,3,4,5,6) on the number cube. So theoretically, the chances of rolling an odd number are 3/6 = 1/2 = 0.5
When we do the experiment, we roll an odd number 325 times out of 500 trials total. So the experimental probability is 325/500 = 0.65
Comparing the results of 0.5 and 0.65, we see that 0.65 is larger. So the experimental probability is larger.
Note: with a large number of trials, the experimental probability should get closer and closer to the theoretical probability. This is assuming that all trials are independent of one another and the number cube is properly weighted.
