(probability) Getting a sum of either 5 or 9 on a roll of two dice

Mathematics
1 answer:
MAVERICK [17]3 years ago
8 0

Answer:

2/9

Step-by-step explanation:

From the image, the total number of outcomes when two die are rolled = 36

It can also be seen that a sum of 5 can be got 4 times and a sum of 9 can be got 4 times too

Therefore, the probability of getting a sum of 5 = 4/36

Probability of getting a sum of 9 = 4/36

The probability of getting either a sum of 5 or 9 gives;

4/36 + 4/36

= 2/9

Find the equation of the tangent line to the graph of f(a) = sec(a) at the point (0, 1).
Paladinen [302]
Let the required equation be y = mx + c; where y = 1, m = f'(0), x = 0
f(a) = sec(a)
f'(a) = sec(a)tan(a)
f'(0) = sec(0)tan(0) = 0

y = mx + c
1 = 0(0) + c
c = 1

Therefore, required equation is
y = 1.

Question 2 Two trains leave the station at the same time, one heading west and the other east. The westbound train travels at 95
lianna [129]

Answer:

it will take 1.4 hours for the two trains to be 294 miles apart

Step-by-step explanation:

Let t be the time taken for each train

The westbound train travels at 95 miles per hour.

Speed of westbound train = 95

time = t

Distance = speed * time = 95 t

The eastbound train travels at 115 miles per hour

Speed of eastbound train = 115

time = t

Distance = speed * time = 115 t

both trains are 294 miles apart means the distance between both trains are 294 miles

So we add the distance of both trains and set it equal to 294

95t + 115t = 294

210 t =294

t = 1.4

So, it will take 1.4 hours for the two trains to be 294 miles apart
