Circumference is pi x diameter so we have to divide 600 by pi to get the actual diameter. 600÷3.14=191cm, so her estimate was a little too small

Answer:

Step-by-step explanation:

A. Little too large

Because

C= (Pi)*d

600=(pi)*200

So the answer is the A.

Problem PageQuestion Tony estimated the height of his office building to be 45ft. The actual height of his office building is 41

Leona [35]

Answer:

The absolute error is 4 ft and percent error of Tony's estimate is 9.8%.

Step-by-step explanation:

Given:

Tony estimated the height of his office building to be 45ft. The actual height of his office building is 41ft.

Now, to find the absolute error and the percent error of Tony's estimate.

The height of his office building = 45ft.

The actual height of his office building = 41 ft.

So, to get the absolute error:

The height of his office building - the actual height of his office building

$45\ ft-41\ ft\\=4\ ft.$

The absolute error = 4 ft.

Now, to get the percent error of Tony's estimate:

$\frac{4}{41} \times 100$

$=0.0975\times 100$

$=9.75\%.$

Percent error of Tony's estimate rounding to nearest tenth = 9.8%.

Therefore, the absolute error is 4 ft and percent error of Tony's estimate is 9.8%.

gladu [14]

Answer:

Answer is: A(Linear)

Step-by-step explanation:

A linear function is a function whose graph is a straight line.

It is given that Mary plotted a graph and she found out that the difference in the y values is the same. So such a thing could happen when a function is a linear function.

since, a linear equation is given as:

$y=ax+b$ where a and b are real numbers.

so for distinct values of x say $x_{1},x_{2}$ we get the y-values as $y_{1},y_{2}$

now,

$y_{1}-y_{2}=a(x_{1}-x_{2})$

so for equally spaced $x_{i}'s$ we get the difference in y-value to be equal.

Hence, the function is Linear.
