\(\frac{1}{5}\)
\(\frac{2}{5}\)
\(\frac{3}{5}\)
\(\frac{4}{5}\)
Correct answer is C
pr. (More than one pet)
= \(\frac{\text{No. of students with > 1 pet}}{\text{total no. of students}}\)
= \(\frac{5 + 10 + 3}{30}\)
= \(\frac{18}{30}\)
= \(\frac{3}{5}\)
Given that \(\frac{5^{n +3}}{25^{2n -3}}\) = 5º, find n
n = 1
n = 2
n = 3
n = 5
Correct answer is C
\(\frac{5^{n +3}}{25^{2n -2}}\) = 5o
\(\frac{5^{n + 3}}{5^{2(2n - 3)}}\) = 5o
n + 3 - 4n + 6 = 0
-3n + 9 = 0
-3n = -9
n = \(\frac{-9}{-3}\)
n = 3
6.0cm
5.5cm
5.0cm
4.5cm
Correct answer is A
Volume of water in tank = l x b x h = 180 litres
but 1 litre = 1000cm2
250 x 120 x hw = 180 x 1000
hw = \(\frac{180 \times 1000}{250 \times 120}\)
= 6cm
Solve the inequality: 3(x + 1) \(\leq\) 5(x + 2) + 15
x \(\geq\) -14
x \(\leq\) - 14
x \(\geq\) -11
x \(\leq\) - 11
Correct answer is C
3(x + 1) \(\leq\) 5(x + 2) + 15
3x + 3 \(\leq\) 5x + 10 + 15
3x - 5x \(\leq\) 10 + 15 - 3
-2x \(\leq\) 22
x \(\geq\) \(\frac{-22}{2}\)
x \(\geq\) -11
Given that = {x: -2 < x \(\leq\) 9}, where x is an integer what is n(T)?
9
10
11
12
Correct answer is C
T = {-1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
n(T) = 11
