Answer:
Step-by-step explanation:
If you are solving to find out what the absolute value of -19 is, it is 19.
Whether it is a negative or positive number, the absolute value is how many numbers away from zero on your number line.
I believe the correct answers are 534 over 999 and 178 over 333.
Because a fraction is basically division, when you divide 534 by 999 you get 0.534. The same thing goes for when you divide 178 by 333.
534/999=0.534
178/333=0.534
Answer:
0.575
Step-by-step explanation:
There are two types of probabilities:
1. Theoretical Probability
2. Experimental Probability
The probability based on mathematical theories is called theoretical probability. It is not always true. i.e. the probability of getting a head in a toss of coin is 1/2 or 0.5 or 50%
Experimental probability is based on experiments. Experimental probability is always going to change whenever the experiment is performed.
The theoretical probability of getting a head while tossing a coin will always be 50% while experimental probability might be different the next time, experiment is performed.
In this case, the experimental probability will be 23/40 or 0.575 ..
6.945 seconds was the difference between Nancy's and Betty's swim times.
27.949 - 21.004 = 6.945
Answer:
r = 28.28
Step-by-step explanation:
you already gave the equation: sin45°= 20/r
you wanna start by multiplying both sides by r. You do this so that your variable can be in the numerator and it will be easier to solve the equation:
r (sin45°) = 20
Now you divide both sides by sin45°, this will give you your final answer. For this, you have to put it in a calculator:
r = 28.28
P.S, good job on already knowing your equation... when i was learning this it took me a while to get eh hang of it :)
