Answer: 119+1=120
121-1=120
60*2=120
Step-by-step explanation:
It is what it is
Answer:
The frequency of f(x) is two times the frequency of the parent function.
Step-by-step explanation:
We can say that the number that is beside the x is equal to 
, where f is the frequency.
Then, for the parent function, we get:
or solving for 
:
At the same way, for f(x), we get:
But 
is equal to , so we can write the last equation as:
It means that the frequency of f(x) is two times the frequency of the parent function.
1 liter is the same thing as 1000 milliliters. (Milli literally means 1000)
Thus 2 liters is 2000 milliliters.
From the list of 9 weights we see that
Puppies in range 10-11 = 3
range 12-13 = 4
range 14-15 = 2
The second histogram described is the correct one.
Let the number of apples be x and that of pears be y, then:
0.64x + 0.45y = 5.26 . . . (1)
0.32x + 0.39y = 3.62 . . . (2)
(2) x 2 => 0.64x + 0.78y = 7.24 . . . (3)
(1) - (3) => -0.33y = -1.98
y = -1.98 / -0.33 = 6
From (2), 0.32x + 0.39(6) = 3.62
0.32x = 3.62 - 2.34 = 1.28
x = 1.28 / 0.32 = 4
Therefore, he bought 4 apples and 6 pears.
