For the set of numbers 2, 3, 5, 6, 7, 7, 8
The median is greater than the mode
The mean is greater than the mode
The mean is greater than the median
The median is equal to the mean
The mean is less than the median
Correct answer is E
Mean = 5, 42
Median = 6
Mode = 7
The mean is less than the median

Correct answer is B
12 men in 9 days,
1 day in \(12 \times 9\) men
In 6 days we have \(\frac{12 \times 9}{6}\) men
= \(\frac{108}{6}\)
= 18 men
Find the value of log\(_{10}\)\(\frac{1}{40}\), given that log10\(_4\) = 0.6021
1.3979
2.3979
-1.6021
2.6021
Correct answer is C
log\(_{10}\)\(\frac{1}{40}\) = log\(_{10}\)1 - (log\(_{10}\)4 + log\(_{10}\)10)
= 0 - 1.6021
= -1.6021
Find the value of (4\(^{\frac{1}{2}}\))\(^6\)
1
2
4
6
64
Correct answer is E
The powers will multiply when the bracket is expanded
The multiplied powers: \(\frac{1}{2}\) * 6 → 3
: 4\(^3\) = 4 * 4* 4
→ 64
If x3 - 12x - 16 = 0 has x = -2 as a solution then the equaion has
x = -4 as a solution also
3 roots all different
3 roots with two equal and the third different
3 roots all equal
only one root
