In throwing a dice, there are 6 possible outcomes, namely 1, 2, 3, 4, 5 and 6.
P=(no. of favourable outcomes)/(no. of possible outcomes)
When we multiply the probability of an event with no. of trials, the we get the expected frequency of that event.
1) P(getting 1)=1/6
expected frequency of getting 1
=P(getting)1)×no. of trials
=1/6×600=100
But it is given that one is scored 200 times, so it makes a large difference from expected frequency, which is 100.
Therefore, the dice is not fair.
2) P(getting a tail)=0.3
estimate for the number of times the coin will land on a tail
=expected frequency of getting a tail
=P(getting a tail)×no. of trials
=0.3×150=45
3)P(getting a six)=2/3
expected frequency of getting a six
=P(getting a six)×no. of trials
=2/3×300=200
4)P(getting a three)=0.5
expected frequency of getting a three
=P(getting a three)×350
=0.5×350=175
Answer:
27
Step-by-step explanation:
Answer:
412.15 ft to the nearest hundredth
Step-by-step explanation:
You have to use the tangent function since you are given one leg of a right triangle and you are looking for the other leg
Let x = the distance from boat to lighthouse
So, tan 27 = 210/x
x tan 27 = 210
x = 210/tan 27
x = 412.14820 = 412.15 ft to the nearest hundredth
Answer:
c. 63°
Step-by-step explanation:
since quadrilaterals = 360°
therefore you add all angles and subtract from 360°
90°+90°+117°=297°
360°-297°=63°
