Answer:
1
3
130
Step-by-step explanation:
as shown on the lines, it takes the bird one second to fly 13 meters. the answer to the first blank is 1
using this ratio, 13 meters per second, we can find how long it takes for the bird to fly 39 meters.
13/1=39/x
this is 13x=39
x=3 seconds
use the same ratio to find distance
13/1=x/10
13=x/10
130=x
Her unit rate is 5 miles per hour.
Answer:
the denominator of the expression is 3n-2
Answer: Yes
Step-by-step explanation:
Yes, because
35.75 + 2.80 = 38.55
So you would have $1.45 left
Answer:
0.6517
Step-by-step explanation:
Given that in a certain game of chance, your chances of winning are 0.3.
We know that each game is independent of the other and hence probability of winning any game = 0.3 (constant)
Also there are only two outcomes
Let X be the number of games you win when you play 4 times
Then X is binomial with p = 0.3 and n =4
Required probability
= Probability that you win at most once
=
We have as per binomial theorem
P(X=r) =
Using the above the required prob
= 0.6517
