There are nine species of Impatiens (balsams) found in laterite plateaus of the northern Western Ghats, each with a distinct colour. If a plateau has exactly 6 species, then the number of possible colour combinations in the plateau is ….. (Answer in integer).

In linear regression, mean squared regression (effect variance) divided by mean squared error (error variance) is called the:
During a half-moon phase, the Earth-Moon-Sun form a right triangle. If the Moon-Earth-Sun angle at this half-moon phase is measured to be \(89.85^\circ\), the ratio of the Earth-Sun and Earth-Moon distances is closest to:
A researcher measures the heights of 200 randomly selected individuals of a tree species in a forest. Which one of the following is NOT a measure of variability in the sample?
Which one of the given options is a possible value of \(x\) in the following sequence? 3, 7, 15, x, 63, 127, 255
In the given text, the blanks are numbered (i)–(iv). Select the best match for all the blanks. Text: From the ancient Athenian arena to the modern Olympic stadiums, athletics \_\_\_\_ (i) the potential for a spectacle. The crowd \_\_\_\_ (ii) with bated breath as the Olympian artist twists his body, stretching the javelin behind him. Twelve strides in, he begins to cross-step. Six cross-steps \_\_\_\_ (iii) in an abrupt stop on his left foot. As his body \_\_\_\_ (iv) like a door turning on a hinge, the javelin is launched skyward at a precise angle.
In the 4 × 4 array shown below, each cell of the first three columns has either a cross (X) or a number, as per the given rule.

Rule: The number in a cell represents the count of crosses around its immediate neighboring cells (left, right, top, bottom, diagonals). As per this rule, the maximum number of crosses possible in the empty column is:
Three distinct sets of indistinguishable twins are to be seated at a circular table that has 8 identical chairs. Unique seating arrangements are defined by the relative positions of the people. How many unique seating arrangements are possible such that each person is sitting next to their twin?
For positive integers \( p \) and \( q \), with \( \frac{p}{q} \neq 1 \), \( \left( \frac{p}{q} \right)^q = p^{q-1 \). Then, which of the following is true?}
On a given day, how many times will the second-hand and the minute-hand of a clock cross each other during the clock time 12:05:00 hours to 12:55:00 hours?
The chart given below compares the Installed Capacity (MW) of four power generation technologies, T1, T2, T3, and T4, and their Electricity Generation (MWh) in a time of 1000 hours (h). The Capacity Factor of a power generation technology is: \[ \text{Capacity Factor} = \frac{\text{Electricity Generation (MWh)}}{\text{Installed Capacity (MW)} \times 1000 \, (h)} \] Which one of the given technologies has the highest Capacity Factor? \includegraphics[width=0.5\linewidth]{8.png}
If '\(\rightarrow\)' denotes increasing order of intensity, then the meaning of the words [\textit{simmer} \(\rightarrow\) \textit{seethe} \(\rightarrow\) \textit{smolder}] is analogous to [\textit{break} \(\rightarrow\) \textit{raze} \(\rightarrow\) \_\_\_\_\_\_]. Which one of the given options is appropriate to fill the blank?
In a locality, the houses are numbered in the following way:The house-numbers on one side of a road are consecutive odd integers starting from \(301\), while the house-numbers on the other side of the road are consecutive even numbers starting from \(302\). The total number of houses is the same on both sides of the road. If the difference of the sum of the house-numbers between the two sides of the road is \(27\), then the number of houses on each side of the road is:
