Question
3/5 of students at a school are boys. If there are 2420 students at the school, how many are girls?
Answer:
<h2>
968 girls</h2>
Step-by-step explanation:
if 3/5 are boys 2/5 are girls (5 - 3/5 = 2/5)
so 2420 * 2/5 = 968 girls
Answer:
i) k = 36.8
ii)y = 36.8/square root of x
iii)y = 1.4
Step-by-step explanation:
If y is inversely proportional to square root of x;
then the two variables are related by,
y = k/ square root of x
i)Value of k when...x = 8 and y = 13,
substitute into the equation above..so as to find the value of k
13 = k/square root of 8
;k = 13 × square root of 8
;k = 36.8
ii)Then substitute the value of k with...36.8
y = 36.8/square root of x
iii)If x = 27...then y =;
y = 36.8/27
y = 1.4
(b) is correct, as it deals with the observed probability of an event and is general enough to apply to any murder sample size.
Answer:
is there a graph that needs to go with it?
If the alternate interior angles (2x-5) and 95, are equal, then the lines L and m are parallel.
2x-5 = 95
2x-5+5 = 95+5
2x = 100
2x/2 = 100/2
x = 50
Answer: 50
