A radar gun measured the speed of a baseball at 92 miles per hour.

If the baseball was actually going 90.3 miles per hour, what was the percent error in this measurement?

Answers

Answer 1

Answer:

subtract the actual measurement from the initial measurement

ie. 92-90.3 =1.7 %

Answer 2

You can calculate the error and then measure how much percent of the real value, the error came.

The percent error in the considered measurement is of approx 1.88%

How to calculate the percent error?

Suppose the actual value and the estimated values after the measurement are obtained. Then we have:

Error = Actual value - Estimated value

To calculate percent error, we will measure how much percent of actual value, the error is, in the estimated value.

[tex]\text{Percent error} = |\dfrac{Error}{\text{Actual value}}| \times 100 = |\dfrac{\text{(Actual value - Estimated value)} }{\text{Actual value}}| \times 100[/tex]

Sine in the given condition, we have:

Actual measurement = 90.3 miles per hourEstimated measurement = 92 miles per hour

Thus, we have

Error = 90.3 - 92 = -1.7 miles per hour

Thus, the percent error is calculated as:

[tex]\text{Percent error} = |\dfrac{-1.7 }{90.3}|\times 100 = \dfrac{1.7 \times 100}{90.3} = \dfrac{170}{90.3} \approx 1.88\%[/tex]

Thus,

The percent error in the considered measurement is of approx 1.88%

15. BD is 30 and half of that is BC or 15. AB and BC have same length so it is also 15.

16. ED and BE have same length so it is also 11.

17. BD is twice of AB so if AB is 14, BD will be 28.

Five positive integers have
 a mode of 9,
 and a median of 7,
 and a mean of 6.
What is the greatest possible range of the five integers?

Answers

Answer:

5

Step-by-step explanation:

The mean is 6 and there are 5 intergers.

You'd multiply 5*6=30. That means that the sum is 30.

The values could be: 2 3 7 9 9

These values add up to 20

Have a mode of 9

Have a median of 7

Have a mean of 6

To find the range you would subtract 9 and 2. That gives you 5.

(i don't know if that's the greatest possible range. But 5 would be the range here)

It is False. 1 is the identity element for multiplication, because if you multiply any number by 1, the number doesn’t change. Identity elements are specific to each operation (addition, multiplication, etc.). So while 1 is the identity element for multiplication, it is NOT the identity element for addition.
