Answer:
13.86 ft/sec
Step-by-step explanation:
If we let x = distance batter has run at time t and D = distance from second base to the batter at time t, then we know 
and we want 
when he is halfway (at x = 45).
Using Pythagoras theorem
When x=45
Thus, when the batter is halfway to first base, the distance between second base and the batter is decreasing at the rate of about 13.86 ft/sec.
Answer:
Relative Frequency Method
Step-by-step explanation:
If I carry out an experiment involving 25 throws of a coin and I obtain 13 Heads(H), the Relative Frequency of obtaining Heads will be 13/25.
Now if I intend to find out approximately how many Heads will
occur in 300 throws, I simply use the result or experimentation data that I have.
This is done below:
Relative Frequency of Obtaining a Head= 13/25 =0.52
Number of Heads obtained in 300 throws
= Relative Frequency X Number of Trials
=0.52 X 300
=156
This is an example of how relative frequency method works.
Answer:
6.25 lb and 100 oz
Step-by-step explanation:
One lb (Pound) is equal to 16 oz (Ounce). Therefore, 100 oz equals...
100 oz / 16 = 6.25 lb
and
100 oz = 100 oz
Given:
Claire is 2 year younger than her sister.
The sum of ages is no less than 44 years.
To find:
Inequality and find the youngest age Claire can be.
Solution:
Let the age of Claire be x.
Her sister's age = x+2
Sum of their ages is no less than 44 years. It means the sum ages is greater than or equal to 44.
Divide both sides by 2.
It means, Claire age can be greater than or equal to 21. So, the youngest age Claire can be 21 years old.
Therefore, the required inequality is and the correct option is B.
