Look at the first element of each point:

{4, 1, 0, 1}   (do not write 4 twice, even tho' 4 shows up twice).

This is NOT a function, altho' it still is a relationship.  Why?   Because 4 shows up as an input twice.  In the case of a function, no input shows up more than once.

Use the following flowchart to determine if the family qualifies for bankruptcy. Their yearly income is 58,000- the median annua
Hatshy [7]

Answer:

Do not qualify

Step-by-step explanation:

Yearly income = $58000

Monthly income = \frac{58000}{12} = $4833.33

Median annual income = $47778

Monthly expenses = $4600

Income < Median Income ? 58000 < 47778 -> No

x = (Monthly income - expenses) * 60

  = (4833.33 - 4600) * 60

  = 233.33 * 60

  = 13999.8

x < 10000 ? 13999.8 < 10000 -> No

So, Do not qualify

A brick of mass 4 kg hangs from the end of a spring. When the brick is at rest, the spring is stretched by 3 cm. The spring is t
Zielflug [23.3K]

Answer:

Step-by-step explanation:

In this system we have the force of the spring and the gravitational force. The equation that describes that is

F_{s}+F{g}=ma\\k(y_0+y)-mg=ma

where y0 is the equilibrium position when the string is free and y0+y is the new equilibrium position when the object is hanged of the string. By replacing by derivatives we have

ky_0+ky-mg=ma\\mg+ky-mg=ky=ma\\\\ky=m\frac{d^2y}{dt^2}\\\\my''+ky=0

the solution for this differential equation is (by using the characterisic polynomial)

y(x)=Acos(kt)+Bsin(kt)\\k=\omega^2m

hope this helps!!

xxMikexx [17]

Answer:

a. The empirical rule.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed(bell-shaped) random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

So the correct answer is:
