Answer:
Step-by-step explanation:
Given function:
where:
- h = height (in feet)
- t = times (in seconds)
Rewrite in the form 
The quickest way to do this is to expand and compare coefficients with the original function.
Comparing coefficients with
Therefore, substituting the found values into the equation:
Answer: D. The probability of a time from 75 seconds to 250 seconds.
Step-by-step explanation:
We know that a density curve graph for all of the possible values from a to b can be used to find the the probability of the values from a to b .
Given: A density graph for all of the possible times from 50 seconds to 300 seconds.
Then it can be used to find the the probability of a time in the range from 50 seconds to 300 seconds.
From all the given option only option D gives the interval which is lies in the above range.
i.e A density graph for all of the possible times from 50 seconds to 300 seconds can be used to determine the probability of a time from 75 seconds to 250 seconds.
Answer:
x= 3126/125 or x=25.008 or as a mixed number form: x=25 and 1/125
Step-by-step explanation:
isolate the variable by dividing each side by factors that don't contain the variable.
He originally had on his MP 3 player 99 songs
Step-by-step explanation:
The given is:
- George deleted 63 songs from his MP 3 player
- The ratio of songs he deleted to the songs he kept was 7 : 4
We need to find how many songs he originally had on his MP 3 player
Let us solve this problem by using the ratio method
∵ George deleted 63 songs from his MP 3 player
∵ The ratio of songs he deleted to the songs he kept was 7 : 4
→ Deleted : Kept : total
→ 7 : 4 : 11 (7 + 4 = 11)
→ 63 : : x
By using cross multiplication
∵ x × 7 = 63 (11)
∴ 7 x = 693
- Divide both sides by 7
∴ x = 99
∵ x represents the total number of songs
∴ He had 99 songs originally
He originally had on his MP 3 player 99 songs
