The ERROR Josephina and Dario estimated √50 are such as 0.07 and -17.92.
<h3>How to calculate the error?</h3>
Suppose the actual value and the estimated values after the measurement are obtained. Then we have:
Error = Actual value - Estimated value
WE need to find the error Josephina and Dario are estimating √50
The actual value of
So,
By Josephina
Error = Actual value - Estimated value
Error = 7.07 - 7
Error = 0.07
By Dario
Error = Actual value - Estimated value
Error = 7.07 - 25
Error = -17.92
Hence, the ERROR Josephina and Dario estimated √50 are such as 0.07 and -17.92.

The other solution to the equation is -3.
Step-by-step explanation:
Given equation is;
5x²+bx+12=0
One solution is -4/5
We will put this solution in Eqn to get the value of b first,
Multiplying each term by 5
Dividing both sides by -4
Putting b=19 in given Eqn
5x²+19x+12=0
Here,
a=5 , b=19 , c=12
Using quadratic formula,
Either, or,
The other solution to the equation is -3.
