Answer:
The y intercept is (0,5)
Step-by-step explanation:
f(x) = 5 * (1/6)^x
What is the y intercept? Let x = 0
f(0) = 5 * (1/6)^0
f(0) = 5*1 = 0
The y intercept is (0,5)
18.
8 divided by 4/9 is 18.
Work: ( / = divided symbol )
8 / 4/9
8/1 • 9/4 = 18
Subtract 16x from each side. Then divide each side by 16, and It'll say " b = something " . That's the answer. Seriously.
Step-by-step explanation:
equation y =
When x = -1
y = = (Answer)
When x = 0,
y = = 1 (Answer)
When x = 3,
y = = 216 (Answer)
Answer:
We know that below the third quartile we have 75% of the values and below the first quartile we have 25% of the values. Then between the third and the first quartile we will have 75-25%=50% of the values.
And then we can apply the following proportion rule:
And solving for x we got:
So then the total of students is approximately 708
Step-by-step explanation:
We know that 354 students are between 100 and 130 so then the interquartile range is:
We know that below the third quartile we have 75% of the values and below the first quartile we have 25% of the values. Then between the third and the first quartile we will have 75-25%=50% of the values.
And then we can apply the following proportion rule:
And solving for x we got:
So then the total of students is approximately 708
