Explanation

Feedback is a supportive communication tool in assessment that encourages growth, trust, and collaboration between teacher and learner.

It is typically non-threatening and focuses on improvement, not judgment, making it key to effective learning.

Explanation

Fever is a symptom, not a disease—it indicates the body’s response to infection or illness.

It reflects an underlying condition like viral or bacterial infections, signaling the immune system is active.

Explanation

A probability greater than 0.5 but less than 1 indicates that the event is more likely than not to occur.

A probability of 1 means certainty, so anything between 0.5 and 1 leans toward happening.

Explanation

Joining the midpoints of an equilateral triangle forms 1 smaller triangle inside.

That smaller triangle and 3 corner triangles (each between a vertex and midpoints) make a total of 4 triangles.

Explanation

The triangle with vertices A(1,2), B(0,4), and C(3,5) has two sides of equal length.

This makes it an isosceles triangle, where at least two sides are equal.

Explanation

MRI (Magnetic Resonance Imaging) uses a strong magnetic field and radio waves to create detailed images of organs and tissues.

It does not use ionizing radiation, unlike X-rays or CT scans.

Explanation

Explanation

Calcium carbonate (CaCO₃) is insoluble in water due to its strong ionic lattice and low solubility product.

In contrast, salts like sodium and potassium compounds are generally highly soluble in water.

Explanation

Given tan θ < 0 and cos θ > 0:

Since cos θ > 0, θ lies in either the 1st or 4th quadrant.

Given tan θ < 0, θ lies in either the 2nd or 4th quadrant.

Combining both conditions, θ must lie in the 4th quadrant.

Explanation

To evaluate the expression, we need to find a common denominator. The least common multiple (LCM) of 9, 8, and 3 is 72.

Let's convert each fraction:

7/9 = (7 × 8) / (9 × 8) = 56/72

6/8 = (6 × 9) / (8 × 9) = 54/72

6/3 = (6 × 24) / (3 × 24) = 144/72

Now, add the fractions:

56/72 + 54/72 + 144/72

= (56 + 54 + 144) / 72

= 254/72

Simplify the fraction:

254/72 = 127/36
