Evaluate the expression 5 /6 + -3 /5

Karo-lina-s [1.5K]

Step-by-step explanation:

$\frac{7}{30}$

$\frac{5}{6} + ( - \frac{3}{5} ) \\ lcm = 30 \\ \frac{25 + ( - 18)}{30} = \frac{7}{30}$

A quality report for a production line shows a score of 59 points on a 65- point inspection test. A passing score is 95% complia

Sholpan [36]

Answer:

The line production did not pass inspection

Step-by-step explanation:

* Lets explain how to solve the problem

- To calculate the percentage of one number with respect to another

divide the number by the another number and multiply the answer

by 100 to convert the answer to percentage

- Ex: 15 people out of a total of 25 were female

the percentage of the female is $\frac{15}{25}*100%=60%$

* Lets solve the problem

- A quality report for a production line shows a score of 59 points on

a 65- point inspection test

- A passing score is 95% compliance

- We need to know did the production line pass inspection

∵ The score of the line production is 59 out of 65

∴ The percentage of the score = $\frac{59}{65}*100%=90.77%$

∴ The percentage of the line production is 90.77%

- The passing score is 95% compliance

∵ 90.77% is less than 95%

∴ The line production did not pass inspection

1. Find the function f (x) =ax2 + bx+ c whose graph contains the points (1, 2), (-2,-7), and (2, -3). Write the system of equati

IRISSAK [1]

Answer:

1. The function is -2x^2 + x + 3.

Step-by-step explanation:

1. The point at (1,2) gives the equation:

a * (1^2) + 1b + c = 2

a + b + c = 2

The point at (-2,-7) gives the equation:

a * (-2^2) + (-2b) + c = 7

4a - 2b + c = -7

The point at (2,-3) gives the equation:

a * (2^2) + 2b + c = -3

4a + 2b + c = -3

Hence, all three equations are:

a + b + c = 2

4a - 2b + c = -7

4a + 2b + c = -3

Now, subtract the second equation from the third equation to get:

(4a + 2b + c) - (4a - 2b + c) = -3 - (-7)

4a - 4a + 2b + 2b + c - c = -3 + 7

4b = 4

b = 1

Hence, let's now update our previous equations:

a + 1 + c = 2 => a + c = 1

4a - 2(1) + c = -7 => 4a + c = -5

4a + 2(1) + c = -3 => 4a + c = -5

This can be further whittled down into two equations:

a + c = 1

4a + c = -5

Hence, we can now subtract the first equation from the second to get:

(4a + c) - (a + c) = -5 - 1

4a - a + c - c = -6

3a = -6

a = -2

Therefore, c = 3 (a + c = 1, -2 + c = 1, c = 1 + 2, c = 3).

And the function is -2x^2 + x + 3.

Hope this helped!
