Answer:
c. Not significant at .055
Step-by-step explanation:
When a pair of dice is rolled, we have 6²=36 possible outcomes. Only 2 of these outcomes have a total score of 11:
- When the first dice is 5 and the second is 6.
- When the first dice is 6 and the second is 5.
Then, we can calculate the probability of getting 11 as the quotient between the successs outcomes and the total outcomes.
Then, the probability of getting 11 is:
This probability is not equal or less than 0.05, so it is not significant at 0.055.
The velocity of the bus is:
velocity (bus) = 36 miles / 40 min
velocity (bus) = 0.9 miles / min
Since the car is 1.5 times faster, so the velocity of the
car is:
velocity (car) = 1.5 * 0.9 miles / min
velocity (car) = 1.35 miles / min
At the meeting point, the sum of the distance is equal to
36 miles. Therefore:
1.35 t + 0.9 t = 36
2.25 t = 36
t = 16 min
So they will meet after 16 minutes.
Answer:
1. 2x - 5 + x = 20
Step-by-step explanation:
Let Aseem's car as x,
Stana's = 5 less than 2x
= 2x - 5
Aseem's + Stana's = 20
x + 2x - 5 = 20
2x - 5 + x = 20
Is that IXL? Anyway I think it’s 8 but I don’t think so anyway I tried don’t rely on me
