Answer:

The least 5th score is 177

Step-by-step explanation:

Given

First\ 4: 103, 143, 101, 110.

Average = 126.8

Required

The least 5th score

Represent the 5th score with x.

The average is calculated as:

Average = \frac{\sum x}{n}

So, we have:

126.8 = \frac{103 + 143 + 101 + 110 + x}{5}

126.8 = \frac{457 + x}{5}

Multiply both sides by 5

634= 457 + x

Solve for x

x = 634- 457

x = 177

Natali [406]

Options

The circle at the new location has _____________ the original circle.

- the same center as

- twice the circumference of

- half the radius of

- the same area as

Answer:

the same area as

Step-by-step explanation:

When a circle is translated and reflected, the center of the circle will change; however, its area, circumference, radius and diameter remain the same.

This is so because, translation and reflection only affect the positioning of the circle not the size.

Considering the above analysis, we can conclude that option d answers the question correctly.
