3 our of 5 in two equivalent forms
sammy [17]
Hello!

3 out of 5 looks like this as a fraction:

3/5

We cannot divide this further as both the numerator and the denominator are odd numbers, so we must multiply to get an equivalent fraction:

3/5 = 6/10 = 60/100

3/5 is also equivalent to 0.2 as a decimal or 20% as a percentage.

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

What point divides the line segment between (10,-2) and (-6,6) into a ratio of 5:3
olganol [36]

Answer: (0,3)

Step-by-step explanation:

You follow the formulas to find the x and y of the dividing points.

Xp= x1+ a/a+b (x2-x1)

Xp= 10+5/5+3(-6-10)

Xp=10+5/8(-16)

Solve the problem above and you end up with “0” as your x.

Yp= y1+ a/a+b (y2-y1)

Yp= -2+ 5/8 (6+2)

Yp= -2+ 5/8 (8)

Solve this problem above and you end up with “3” as your y. Therefore, the point that divides the line segment between (10, -2) and (-6,6) into a ratio of 5:3 is (0, 3).
