Answer:

t=d/s

Step-by-step explanation:

search up distance speed time triangle (like the one attached) and memorize it. When u need to use it just draw it on a piece of paper and cover ur intended target. For example, if u want to find the time formula, cover the time section and you got the time formula, D/S. It helps for beginners.

Answer:

(a) Arts take longer

(b) By 2/9 hours

Step-by-step explanation:

Given

Arts = four over nine hours

Maths = two over nine hours

Solving (a): Which takes longer?

First, represent both as fraction

$Arts = \frac{4}{9}\ hours$

$Maths = \frac{2}{9}\ hours$

Convert fraction to decimal

$Arts = \frac{4}{9}\ hours$

$Arts = 0.444\ hours$

$Maths = \frac{2}{9}\ hours$

$Maths = 0.222\ hours$

By comparison:

$0.444 > 0.222$

Hence, Arts take longer

Solving (b): How much longer?

To do this, we calculate the difference.

$Difference = Arts - Maths$

$Difference = \frac{4}{9} - \frac{2}{9}$

Take L.C.M

$Difference = \frac{4 - 2}{9}$

$Difference = \frac{2}{9}\ hours$

Make a table showing the probability distribution for the possible sums when tossing two four-sided dice (the sides are numbered

alexira [117]

We would have the following sample space:
(1, 1), (1, 2), (1, 3), (1, 4)
(2, 1), (2, 2), (2, 3), (2, 4)
(3, 1), (3, 2), (3, 3), (3, 4)
(4, 1), (4, 2), (4, 3), (4, 4)

Those give us these sums:
2, 3, 4, 5
3, 4, 5, 6
4, 5, 6, 7
5, 6, 7, 8

P(sum of 2) = 1/16 =0.0625
P(sum of 3) = 2/16 = 0.125
P(sum of 4) = 3/16 = 0.1875
P(sum of 5) = 4/16 = 0.25
P(sum of 6) = 3/16 = 0.1875
P(sum of 7) = 2/16 = 0.125
P(sum of 8) = 1/16 = 0.0625
