All stars must reach a state of equilibrium in order to be stable. Which two forces are in equilibrium inside a white dwarf?

bagirrra123 [75]

Answer:

I did research and this is what l found from different websites .The inward force of gravity is balanced out by the outward force of pressure to keep the star stable. This stable balance, the outward pressure of hot gases balancing the inward pull of gravity is called the hydrostatic equilibrium.Dont forget to say thanks ✌️

Willa says the slope of the graph is -1/3.What error did she make?

Nataly [62]

ANSWER

She counted the squares instead of using the scale.

EXPLANATION

The slope of a line is calculated using the formula

$m = \frac{rise}{run}$

This is the same as:

$m = \frac{y_2-y_1}{x_2-x_1}$

The given straight line passes through:

(4,24) and (16,18).

We plug in the values to obtain,

$m = \frac{18 - 24}{16 - 4}$

$m = \frac{ - 6}{12}$

$m = - \frac{ 1}{2}$

This is the correct expression for the slope.

But Willa mistakenly counted the squares instead of using the scale and had

$m = - \frac{1}{3}$

Each box on the y-axis is 3 units and each box on the x-axis is 2 units.

The rise is one box along the y-axis which is equal to 3 units the run is 3 boxes which is equal to 6 units.

The line has a negative slope.

Because she just counted the boxes and did use the scale, she got a wrong answer.

A package of 12 cakes costs $6.80. A package of 30 cakes of the same type costs $15.16. Which package is the best buy? Give the

Luba_88 [7]

To answer this question, we will need to get the price of one cake in each package.

For package 1:
The package has 12 cakes and costs $6.80, this means that:
price of one piece = 6.80 / 12 = 0.5666 which is approximately $0.6

For package 2:
The package has 30 cakes and cost $15.16, this means that:
price of one piece = 15.16 / 30 = 0.505 which is approximately $0.5

Comparing the two prices, we will find that the best buy is the second package where the price of one piece is less.

A recent study showed that the length of time that juries deliberate on a verdict for civil trials is normally distributed with

fiasKO [112]

Answer:

0.3999

Step-by-step explanation:

Given that a recent study showed that the length of time that juries deliberate on a verdict for civil trials is normally distributed with a mean equal to 12.56 hours with a standard deviation of 6.7 hours.

Given this information, we are to find the probability that a deliberation will last between 10 and 15 hours

Let X be the length of time that juries deliberate on a verdict for civil trials

10<x<15 can be converted into Z form as

$\frac{10-12.56}{6.7}$

Prob = F(0.678)-F(-0.382) =0.3999

(where F represents cumulative probabilities upto that value)
