Student 4 has the largest percent error.

Step-by-step explanation:

The percent error of a measurement is given by

p=\frac{|x-x_{true}|}{x_{true}}\cdot 100

where

x is the value of the measurement

x_{true} is the actual value

For student 1:

x=49\\x_{true}=50

Percent error:

p=\frac{|49-50|}{50}\cdot 100=0.02\cdot 100=2\%

For student 2:

x=25.5\\x_{true}=25

Percent error:

p=\frac{|25.5-25|}{25.5}\cdot 100=0.0196\cdot 100 = 1.96\%

For student 3:

x=7.5\\x_{true}=8

Percent error:

p=\frac{|7.5-8|}{8}\cdot 100=0.0625\cdot 100 = 6.25\%

For student 4:

x=2.1\\x_{true}=1.6

Percent error:

p=\frac{|2.1-1.6|}{1.6}\cdot 100=0.3125\cdot 100 = 31.25\%

So, student 4 has the largest percent error.

I need help understanding which is a,b, or c​
klemol [59]

Answer:

see explanation

Step-by-step explanation:

Using Pythagoras' theorem, that is

The square on the hypotenuse of a right triangle is equal to the sum of the squares on the other two sides.

Using x instead of ?

(a)

The hypotenuse is the side opposite the right angle, that is 74, thus

24² + x² = 74²

576 + x² = 5476 ( subtract 576 from both sides )

x² = 4900 ( take the square root of both sides )

\sqrt{x^{2} } = \sqrt{4900}

x = 70

----------------------------------------------------------------------

(b)

The hypotenuse x is the unknown side here

x² = 40² + 40² = 1600 + 1600 = 3200

Take the square root of both sides

\sqrt{x^{2} } = \sqrt{3200} ≈ 56.6 ( nearest tenth )

The measures of two angles of a triangle are 75 and 62º. Find the measure of the third angle.
yan [13]

Answer: B 43

Step-by-step explanation:

Well for a triangle it has to be equal to 180 so you would add 75 and 62 to get 137 so you would add each answer to 137 and whichever one equals 180 is the answer therefor stating that the answer is B 43.
