Answer:
We expect 95% of the data to fall between 4.9 and 8.1
Step-by-step explanation:
The 68-95-99.7 rule says that 95% of the data will lie between 2 standard deviations below the mean, and 2 standard deviations above the mean.
2 × SD = 1.6
6.5 - 1.6 = 4.9
6.5 + 1.6 = 8.1
We expect 95% of the data to fall between 4.9 and 8.1
Answer:
(-4,0) and (4,0)
Step-by-step explanation:
The x-intercepts occur for values of x where f(x) = 0.
f(x) = 0 when the nominator () = 0.
is a difference of squares,
so you can factor it as (x + 4)(x – 4)
When x = –4 or x = 4, the nominator is 0, and f(x) = 0
Answer:

m=1,047
Step-by-step explanation:
Uhm..
From what I can understand the height:width ratio is 3:4 so if the width is ten then you will be increasing the ratio by 2.5. So all you have to do is multiply 3 by 2.5.
The height is 7.5cm
