In a certain exam of grade ten, 75% students got high score in mathematics, 65%
1 answer:
(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.

Answer:
Option C) The first equation is y= 2/3x-4 when written in slope-intercept form .
Step-by-step explanation:
We have
The first equation is in Standard form .
Convert to slope Intercept form .
Isolate the Variable y .
Divide by 3 both sides .
The second equation is in slope Intercept form .
Convert to standard form
Multiply by 5 both sides to remove the fraction .
- False
- Because only the second equation is in slope -intercept form
- False
- Because, the second equation is in slope -intercept form
- True (see the procedure)
- False
- Because, the second equation is 3x+5y=10 when written in standard form .
