A typical neutron star has a mass of about 1. 5msun and a radius of 10 kilometers

Triss [41]

How thick a layer would Earth form as it wraps around the neutron star’s surface is: 6.67 10⁻³ m.

<h3>Density of the Neutron star</h3>

Density

ρ = m / V

Where:

ρ= density

m = mass of the planet 5.98 10²⁴ km

V =volume of the spherical layer

Volume of a sphere

Volume = 4/3 π r³

Mass = 1.5 = 1.5 1,991 10³⁰

Mass= 2.99 10³⁰ kg

Density:

ρ = 2.99 10³⁰ / [4/3 π (10 10³)³]

ρ is = 7.13 10 17 kg / m³

V = 5.98 10²⁴ / 7.13 10¹⁷

V = 8,387 10⁶ m³

Thickness of the layer

V = 4π r² e

e = V / 4π r

e = 8,387 10⁶ / [4π (10 10³)²]

e = 6.67 10⁻³ m

Inconclusion how thick a layer would Earth form as it wraps around the neutron star’s surface is: 6.67 10⁻³ m.

Patrick drives from p to q at an average speed of 40mph.

Bumek [7]

The distance in miles from P to Q is 12 miles

<h3>Distances and speed</h3>

Let the distance from P to Q be "d"

Since the formula for calculating speed is expressed as:

s =d/t

For the distance of P to Q

40 = d/t

d = 40t

If he drives back at an average speed of 45mph and 2 mintes less, then;

45 = d/t - 0.033

d = 45 (t - 0.033)

Equating both distances

40t = 45(t - 0.033)

40t = 45t - 1.485

-5t = -1.485
t = 0.297

Get the distance from P to Q:

d = 40(0.297)
d = 11.88 miles

Hence the distance in miles from P to Q is 12 miles

To be fully prepared for a speech, a student should memorize their speech one week in advance and practice three times everyday.

pantera1 [17]

That statement is false

There are other methods that people can for the speech other than memorizing it. Here are two methods that you can use :

- Preparing a text so you can conduct the speech by reading it.

- Preparing a couple of pointers in your hand to help you remember the important topics of the speech.

In a certain region, 94 percent of the people have a certain characteristic in their blood. Suppose a group of 45 people from th

Damm [24]

The best interpretation of the mean is;

Option A; For all groups of 45 people, the average number of people without the characteristic is 2.7

<h3>Interpretation of Mean</h3>

We are given;

Percentage of people with a certain characteristic in their blood = 94%

Number of people selected = 45

Number of people without the characteristic in their blood = B

Now, we are told that B follows a binomial distribution with a mean of 2.7 people.

Now, in statistics, mean is defined as the average of a set of data.

Thus, this mean refers to the average number of people that don't have the characteristic in their blood from the group of 45 people.

The missing options are;

A) For all groups of 45 people, the average number of people without the characteristic is 2.7.

B) Every group of 45 people will have 2.7 people with the characteristic.

C) Every group of 45 people will have 2.7 people without the characteristic.

D) On average, 2.7 people are selected until finding someone with the characteristic

E) On average, 2.7 people are selected until finding someone without the characteristic
