Answer:
Option (1)
Step-by-step explanation:
By using triangle sum theorem in the given triangle,
(5x - 7)° + (11x - 4)° + (3x + 1)° = 180°
(5x + 11x + 3x) - (7 + 4 - 1) = 180
19x - 10 = 180
19x = 190
x = 10
Therefore, (3x + 1)° = 30 + 1
= 30°
(11x - 4)° = 110 - 4
= 106°
(5x - 7)° = 43°
Therefore, Option (1) will be the correct option.
Given that after a discount of 40% a furniture was bought for $438. The original price of the furniture will be calculated as follows:
discount=40%
new percentage price=100-40=60%
Original percentage price=100%
New buying price=$438
therefore, the original price was:
100/60×438
=$730
The original price was $730
Answer:
9 seconds.
Step-by-step explanation:
On your graph, use a ruler and your eye to get the best fitting line.
Then find the time in seconds (45) which is between 40 and 50 on the x axis.
Go across to the y axis. You will find it is about 9 seconds.
The fraction for 469 is 469/1.
Answer:
P (A and B)=8/9
Events A and B are not dependent.
Step-by-step explanation:
Probability of A AND B means the the probability (favorable outcomes divided by total) of choosing someone who has/did BOTH A and B (not neither or only one of them). 16 did both, so the probability is 16/18 /2/2 = 8/9.
The events are independent (not dependent) because choosing A does not affect choosing B.
