In one month, there are on average 30 days.
So if he talks 135 minutes per month, he talks on average 135/30 minutes per day
135/30 = 4.5
So on average he talks to his grandfather for 4 minutes and 30 seconds a day.
Answer:
Length= 8, Width= 4
Step-by-step explanation:
Say the length is l, and the width is w.
We can set l, the length as 2w, as it is double the length.
The perimeter= 2l + 2w= 24
Input l as 2w, get
4w+2w=24
6w=24, w=4.
Length is w*2, so length is 8.
Answer: Option 'B' is correct.
Step-by-step explanation:
Since we know that "Angle opposite to greater side is smaller or angle opposite to smaller side is larger".
So, ∠AOD is opposite to side 'AD' which is equal to 8.11
Similarly, ∠AOB is opposite to side 'AB' which is equal to 8.
So, ∠AOB>∠AOD
Hence, Option 'B' is correct.
Answer:
25%
Step-by-step explanation:
Probability = # of favorable outcomes / possible outcomes
favorable outcomes is what we want to happen ( throwing more than 3 pitches )
So to find the # of favorable outcomes we must find the frequency that the pitcher throws more than 3 pitches ( note: frequency of throwing 3 pitches is not included)
There are two possible outcomes of the pitcher pitching more than 3 pitches, 4 pitches having a frequency of 15, and 5 pitches which has a frequency of 10
So # of favorable outcomes = 10 + 15 = 25
Now we want to find the # of possible outcomes.
To do so we simply add the frequencies of each possible outcome.
15 + 20 + 40 + 15 + 10 = 100
So there are a total of 100 possible outcomes
Finally to find the probability of the pitcher throwing more than 3 pitches we divide favorable outcomes ( 25) by possible outcomes (100)
Our answer = 25/100 which can be converted into a percentage as 25%
