In a certain exam of grade ten, 75% students got high score in mathematics, 65%
faltersainse [42]

(i) The percentage of students who got high scores in both the subjects English and Mathematics is 46%.

(ii) The total number of students who got high scores either in Mathematics or in English if 300 students had attended the exam exists 138.

<h3>What is probability?</h3>

The probability exists in the analysis of the possibilities of happening of an outcome, which exists acquired by the ratio between favorable cases and possible cases.

The number of students who got high scores in Mathematics was 75%.

The number of students who got high scores in English was 65%.

(i) The percentage of students who got high scores in both the subjects

100% - 6% = 94%

(75% + 65%) - 94%

= 140% - 94%

= 46%

Therefore, the percentage of students who got high scores in both the subjects English and Mathematics is 46%.

(ii) The total number of students who got high scores either in Mathematics or in English if 300 students had attended the exam

= 300 * 46%

= 300 * (46 / 100)

= 300 * 0.46

= 138.

Therefore, the total number of students who got high scores either in Mathematics or in English if 300 students had attended the exam exists 138.

Prove that JOYS with vertices j(1,1) o(2,-6) y(3,3) s(2,10) is a parallelogram
zmey [24]

For this you're going to use distance formula

D= square root of (x2-x1)^2 + (y2-y1)^2

To prove this is a parallelogram ALL sides must equal the same or two sides + two sides must be the same.

Find the distance of JO, YS, JS, and OS. If you have too find the distance of JY and OY. Using the formula above. Hope this helps you. If you need further help I can assist you with a problem step by step
