Answer:

Colin gets $\frac{2}{3}$

Step-by-step explanation:

One part is excluded in the problem. That part is:

"Caroline gets $\frac{1}{9}$ of the money."

Solution:

If Caroline gets 1/9th, then remaining is:

$1-\frac{1}{9}=\frac{8}{9}$

Colin and Sarah share in ratio 3 is to 1, that means 3 + 1 = 4 parts...

8/9th in 4 parts means, each part is:

$\frac{\frac{8}{9}}{4}=\frac{2}{9}$

We know Colin gets "3" parts of the total, each part is (2/9)th, so 3 parts would be:

$3*\frac{2}{9}=\frac{6}{9}=\frac{2}{3}$

Colin gets $\frac{2}{3}$

1.An object falls from rest on a high tower and takes 5.0 s to hit the ground. Calculate the object’s position from the top of t

Arte-miy333 [17]

We will be using this equation for this problem
d = ut + ½.at²
Given:
initial velocity, u = 0 (falling from rest) 
acceleration, a = +9.80 m/s²(taking down as the convenient positive direction) 
Time = 1.0s, 2.0s, 3.0s, 4.0s, 5.0s 

Using .. d = ½.at² each time (each calculation is the distance from the top) 
For 1.0s .. d = ½ x 9.80 x (1²) = 4.90 m 
For 2.0s .. d = ½ x 9.80 x (2²) = 19.60 m 
3.0s .. d = 44.10m (you show the working for the rest) 
4.0s .. d = 78.40 m 
5.0s .. d = 122.50m 

Plot distance (displacement from the top) on the y-axis against time on the x-axis (label axes and give units for each).The line of best fit will be a smoothly upward curving line getting progressively steeper. Do not join graph points with straight lines.

On a road map, the locations A, B and C are collinear. Location C divides the road from location A to B, such that AC:CB = 1:2.

koban [17]

Answer:

C. (-1,-2)

Step-by-step explanation:

Since C internally divides AB in the ratio AC/CB = 1/2 = m/n where m = 1 and n = 2, we use the formula for internal division.

Let A = (x₁, y₁) = (5, 16), B = (x₂, y₂) and C = (x, y) = (3, 10)

So x = (mx₂ + nx₁)/(m + n)

y = (my₂ + ny₁)/(m + n)

Substituting the values of the coordinates, we have

x = (mx₂ + nx₁)/(m + n)

3 = (1 × x₂ + 2 × 5)/(2 + 1)

3 = (x₂ + 10)/3

multiplying through by 3, we have

9 = x₂ + 10

x₂ = 9 - 10

x₂ = -1

y = (my₂ + ny₁)/(m + n)

10 = (1 × y₂ + 2 × 16)/(2 + 1)

10 = (x₂ + 32)/3

multiplying through by 3, we have

30 = y₂ + 32

y₂ = 30 - 32

y₂ = -2

So, the coordinates of B are (-1, -2)

Flauer [41]

A discrete variable is a type of variable which contains a finite number of values. It usually takes its values from the set of whole numbers.

From the random variable described, the random variable that is descrete is "You measure the maximum heart rate in beats per minute".

This is because, heart rate cannot be partitioned it only takes counting number values. You either have 1 beat per minutes, 2 or 3 and so on beats per minute. But you cannot have 2.5 or 3.8 and so on beats per minute.
So heart rate cannot take decimal or fractional values and hence, it is a discrete random variable.
