Answer: 45
Step-by-step explanation:
To calculate the probability of the number of times a 1 we appear , we have
number of times a 1 appeared / Total number of times the die is rolled.
Let x represent the number of times a 1 is gotten
And we have been given the probability of getting a 1 and also the total number of times the die is being rolled , substituting this inside the formula above , we have
0.3 = x / 150
x = 150 x 0.3
x = 45

Answer:
the width is 9 23/30 feet ≈ 9.767 ft
Step-by-step explanation:
Let w represent the width of the train car. Then 6 times the width is 6w, and 8 ft less than that is (6w-8). We are told this amount is 50.6 feet, so we have ...
6w -8 = 50.6
6w = 58.6 . . . . . . . add 8; next divide by 6
58.6/6 = w = 586/60 = 293/30 = 9 23/30 . . . . feet
This is a repeating decimal: 9.766666...
The width of the train car is 9 23/30 ft, about 9.77 ft.
Let's try all the answers with the above equation
a) 4 as p and -4 as q
4 - 4 = 8? INCORRECT
b) 10 as p and 1 as q
10 - 1 = 8? INCORRECT
c) -4 as p and 4 as q
-4 - 4 = 8? INCORRECT
d) 11 as p and 3 as q
11 - 3 = 8? correct
5 points, because I think you’re saying they started off with 30 points and they answered a question wrong a lost 25 so 30-25 is 5.
