Based on the cumulative frequency histogram, determine the number of swimmers who swam between 200 and 249 yards. Determine the
Lostsunrise [7]

Answer:

(a)\ 200 \to 249 =3

(b)\ 150 \to 199 = 0

(c)\ Total = 20

Step-by-step explanation:

Given

See attachment for cumulative frequency histogram

Solving (a): Swimmers between 200yd and 249yd

To do this, we simply read the data from the 0 mark

From the histogram, we have:

0 \to 249 = 15

and

0 \to 199 = 12

So:

200 \to 249 = 0 \to 249 - 0 \to 199

This gives:

200 \to 249 = 15-12

200 \to 249 =3

Solving (b): Swimmers between 150yd and 199yd

To do this, we simply read the data from the 0 mark

From the histogram, we have:

0 \to 149 = 12

and

0 \to 199 = 12

So:

150 \to 199 = 0 \to 199 - 0 \to 149

This gives:

150 \to 199 = 12-12

150 \to 199 = 0

Solving (c): Total swimmers

To do this, we simply read the longest bar of the histogram

Longest = 20

Hence:

Total = 20

Through: (4,4), slope<br> 9/4
faltersainse [42]

Answer:

y - 4 = (9/4)(x - 4)

Step-by-step explanation:

Here we're given the slope (9/4) of a line and one point (4, 4) on the line.  The easiest form of the equation of a straight line to use here is the point-slope form:

y - k = m(x - h).

Here h = 4 and k = 4; the slope is m = 9/4.

Thus, the desired equation is

y - 4 = (9/4)(x - 4)

Find the area of the circle. Leave your answer in terms of π.
seraphim [82]

Answer:

4π

Step-by-step explanation:

We are asked to calculate the area of a circle whose diameter is equal to 4, we know that the area of the circle is given by the following equation:

A = π * (r ^ 2)

where r is the radius of the circle, we know that the radius of the circle is half the diameter, therefore:

r = d / 2 = 4/2

r = 2

replacing, we are left with:

A = π * (2 ^ 2)

A = 4π

Which means that the area of the circle is 4π
