The sample mean is 6
<h3>How to calculate the sample mean ? </h3>
Mean can be described as the sum of terms divided by the number of terms
3, 4, 5, 6, 8, 10
3 + 4 + 5+ 6 + 8 + 10/6
= 36/6
6
Hence the sample mean is 6

Answer:
No, the area of the dilated triangle will increase by a factor of 9
Step-by-step explanation:
When the scale factor by which the dimensions is dilated = 3, we have;
The original length of base = b
The base length of the dilated triangle = 3×b
The original height of the the triangle = h
The height of the dilated triangle = 3×h
The original area of the triangle = 1/2 × base × height = 1/2×b×h
The area of the dilated triangle = 1/2 × base of dilated triangle × height of dilated triangle
∴ The area of the dilated triangle = 1/2× 3 × b × 3× h = 9×1/2× b×h
Which gives;
The area of the dilated triangle = 3²×1/2× b×h= (Scale factor)²× The original area of the triangle.
From 3² = 9, we have;
The area of the dilated triangle = 9 × The original area of the triangle.
Therefore;
The area of the dilated triangle will increase by a factor of 9.
Answer:
Exact form: 21/10
Decimal form: 2.1
Mixed Number form: 2 1/10
Step-by-step explanation:
Reduce the expression if possible, do so by canceling out the common factors.
