David is running a 500 m sprint. so far he has run 300 m. what fraction of the spirit does he have left?
?
__
?
what percent?________%

Answers

40 percent is left to run

Answer:

200/500=2/5

40%

Step-by-step explanation:

If the total distance of the sprint is 500m and he's already run 300m, so subtract 500-300 which equals 200.

Then put it in fraction form 500 being the total distance needing to be traveled in all will be your denominator and 200 being the distance left to be traveled will be your numerator. 200/500

Then simplify=200/500 divided by 100/100 equals 2/5.

Then to get it to a percentage divide 2 by 5 which equals .40

Then convert to a percentage 40%

Answer:

A, A, A, B, D

Step-by-step explanation:

P(A) = 1/6, P(B) = 1/2

P(A and B) = 1/6*1/2 = 1/12

P(A) = 1/6

P(B) = 1/6

P(A and B) = 1/6*1/6 = 1/36

P(A) = 2/6 = 1/3

P(B) = 1/3

P(A and B) = 1/3*1/3 = 1/9

P(gold) = 4/7 for each

P(2 golds) = 4/7*4/7 = 16/49

Remaining marbles:

2 white, 1 orange and 2 green. Total 5 marbles

P(green) = 2/5

1.50 5/9(122-32)=5/9(90)= 50

Answer: 50

Step-by-step explanation:

5/9 (f-32) if f = 122 you take 122 and subtract 32 because of order of operations and now you have 5/9 (90) and then you multiply 5/9 times 90 and you get 50

Why does the sum of the two given angles equal 180°? (2x+1)+(x-7)=180

Answers

Answer:

because its a straight line

Step-by-step explanation:

Answer:

Since the sum of the angles is 180 degrees and each angle is represented by the respective algebraic expressions, then to find the value of x, just add the expressions up, set that sum equal to 180, and solve for x. So, (2x-7)+(x+25)+(3x+12)=180 is our equation. Now we just simplify and solve for x.

(2x-7)+(x+25)+(3x+12)=180

6x+30=180 b/c 2x+x+3x=6x and -7+25+12=30.

6x=150 subtract 30 from both sides of the equation

x=25.

may someone please help me understand something in class? its theoretical and experimental probability basically just probability in a whole and I can’t understand. I don’t need the definition I just want someone to make me understand in a simple way like a tutor, but anyways please help me understand this. Examples would work, anything. Just help me understand. Thanks anyways.

Answers

Experimental probability is the results of an experiment, let's say for the sake of an example marbles in a bag. Experimental probability would be drawing marbles out of the bag and recording the results. Theoretical probability is calculating the probability of it happening, not actually going out and experimenting.

Aisha measures the length of a sheet of paper and finds that it is 29 cm long. The label on the package indicates that the paper length is 32 cm. Calculate the percentage error in the measurement.

Answers

Answer:

just do the step by step and you'll probably get it because it's quite simple but hard for me to explain so just read this!

Step-by-step explanation:

In making any measurement, the chances are that our results will not be absolutely accurate. We can often compare our results with some standard or accepted value to see how closely they agree. But how much error can be allowed before the result becomes meaningless?

As you may guess, the amount of error that is acceptable varies with the situation. Suppose you measure the distance on a map between your Scarsdale and Mamaroneck and you get a result of 5 miles. If the actual distance is 5 1/2 miles, the chances are this error will have no effect on the trip between the two towns. But if the same degree of error existed in the calculations used to send astronauts to the moon, those people would be in big trouble!

Percentage Error = measured value - accepted value x 100%

accepted value

Suppose, you measured the length of a table and obtained a measurement of 202 cm. A friend also measures the table and obtains a result of 198 cm. To calculate the percentage error in each of the measurements, you need to know the "correct' or “accepted value” of the length of the table. After consulting the manufacturer’s catalog, you find that the table's length is listed as 200 cm in length. This will be used as the accepted value in our calculation.

The calculations of percentage error for the two measurements are shown below. Both measurements show an error of 1%. Your friend has made a measurement which is on the low side of the accepted value and is therefore, negative. You, on the other hand, have made an error on the high side of the accepted value and it is positive.

I dont know the answer but I hope this helped!
