The probability of getting a number less than 6 is 5/6 if there are 6 sides
Answer:
HDTV Converters
a. The probability that the driver will have enough working converters = 80% (100 - 20%).
b. The driver should load 10 boxes (or specifically 9.5 boxes) to ensure a 95% probability of having enough working converters.
Step-by-step explanation:
a) Data and Calculations:
Probability of HDTV converters known to not work property = 20%
This implies that 80% (100 - 20%) will work properly.
Number of converters to install today in an apartment building = 8
Number of converters placed in the truck = 10
b) The probability that the driver will have enough working converters = the probability of having properly working converters, which is 80%. To ensure a 95 percent probability of having enough working converters, out of 10 converters, the number of boxes to load on the truck is 9.5 (10 * 95%) boxes. Since there are no half boxes, it means that 10 boxes must be loaded, approximated to the nearest convenient number.
It is 16,700 meters to cycle there and back
Answer:
The experimental probability that the next train to arrive will be on time is P(T) = 
= 0.875
Step-by-step explanation:
Experimental Probablity is based on the experiments which we have performed in the past. In this case, of the total number of trains (16), the total number of trains which arrived on time is (14). So the probablity tat the next train to arrive will be on time would be calculated as:
=
= 0.875
8=4(q−2)+4
Step 1: Simplify both sides of the equation.
8=4(q−2)+4
8=(4)(q)+(4)(−2)+4(Distribute)
8=4q+−8+4
8=(4q)+(−8+4)(Combine Like Terms)
8=4q+−4
8=4q−4
Step 2: Flip the equation.
4q−4=8
Step 3: Add 4 to both sides.
4q−4+4=8+4
4q=12
Step 4: Divide both sides by 4.
4q/4=12/4
q=3
Answer:
q=3
