Step-by-step explanation:

The proportion that can be used to show that the slope of JL is equal to the slope of MP is (0 - 4)/(-4 - (-7)) = (-4 - 8)/(-1 - (-10))

How to determine the proportion that can be used to show that the slope of JL is equal to the slope of MP?

From the question, we understand that triangle MNP and triangle JKL are similar right triangles.

This means that triangle MNP and triangle JKL have the same slope

From the figure, we have the following coordinates of the triangles

J = (-7, 4)

L = (-4, 0)

M = (-10, 8)

P = (-1, -4)

The slope is calculated as

Slope = (y2 - y1)/(x2 - x1)

So, we have

JL = (0 - 4)/(-4 - (-7))

Also, we have

MP = (-4 - 8)/(-1 - (-10))

Equate both equations

So, we have

(0 - 4)/(-4 - (-7)) = (-4 - 8)/(-1 - (-10))

Hence, the proportion that can be used to show that the slope of JL is equal to the slope of MP is (0 - 4)/(-4 - (-7)) = (-4 - 8)/(-1 - (-10))

The figures below show the front view and top view of a rectangular prism that is packed with unit cubes. What is the volume of the prism if there are no gaps or overlaps in the unit cubes? ____ cubic unit

Answers

Answer:

60 cubic units

Step-by-step explanation:

The figure is 5 tall, so just add 5 for each square on the top view.

The volume of the rectangular prism is 60 cubic units

What is the Volume of a Rectangle?

The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle

Volume of Rectangle = Length x Width x Height

Volume of Rectangle = Area of Rectangle x Height

Given data ,

Let the volume of the rectangular prism be represented as V

Now , the equation will be

The length of the rectangular prism = 3 units

The width of the rectangular prism = 4 units

The height of the rectangular prism = 5 units

Now , the volume is calculated by

Volume of Rectangle = Length x Width x Height

Substituting the values in the equation , we get

Volume of Rectangle V = 3 x 4 x 5

On simplifying the equation , we get

Volume of Rectangle V = 60 cubic units

Therefore , the value of V is 60 cubic units

Hence , the volume of the rectangular prism is 60 cubic units

Calculate the current in an Inductor if the energy stored is 240J and the Inductance is 24H.

Answers

Answer:

Current, I = 4.47 Amperes.

Step-by-step explanation:

Given the following data;

Inductance = 24H

Energy stored, Eind = 240J

To find the current;

The energy stored in an inductor is given by the formula;

Eind = ½LI²

240 = ½*24*I²

Cross-multiplying, we have;

480 = 24I²

I² = 480/24

I² = 20

Taking the square root of both sides, we have;

Current, I = 4.47 Amp

Prove (triangle)ABC is congruent to (triangle) DEF using ASA

Answers

Answer/Step-by-step explanation:

Two triangles can be proven to be congruent to each other if two angles and an included side of one triangle is congruent to the corresponding two angles and included side of the other triangle.

Two angles (<C and <A) in ∆ABC, are congruent to two angles (<D and <F) in ∆DEF. Also, the included side (AC) in ∆ABC is congruent to the included side (DF) in ∆DEF.

Therefore, based on the Angle-Side-Angle Congruence Theorem, ∆ABC is congruent to ∆DEF.

Henry bought a pair of shoes that were on sale for 25% off. The sale price of the shoes was $42. What was the original price?

Answers

Answer:

$56

Step-by-step explanation:

Find out the percentage of the pair of shoes after the sale discount.

100 - 25 = 75%

75% = 42

1% = 42 ÷ 75 = 0.56

100% is the percentage of the original price.

100% = 0.56 x 100 = 56

Answers

Answer:

the probability that the sample mean is greater than 2.1 but less than 2.4 is 0.2444

Step-by-step explanation:

Given the data in the question;

x f(x) xp(x) x²p(x)

1 1/3 0.33333 0.33333

2 1/3 0.66667 1.33333

3 1/3 1.00000 3.0000

∑ 2.0000 4.6667

∑(xp(x)) = 2

∑(x²p(x)) = 4.6667

Variance σ² = ∑(x²) - ∑(x)² = 4.6667 - (2)² = 4.6667 - 4 = 0.6667

standard deviation σ = √variance = √0.6667 = 0.8165

Now since, n = 33 which is greater than 30, we can use normal approximation

for normal distribution z score ( x-μ)/σ

mean μ = 2

standard deviation = 0.817

sample size n = 33

standard of error σₓ = σ/√n = 0.817/√33 = 0.1422

so probability will be;

p( 2.1 < X < 2.4 ) = p(( 2.1-2)/0.1422) < x"-μ/σₓ < p(( 2.4-2)/0.1422)

= 0.70 < Z < 2.81

= 1 - ( 0.703 < Z < 2.812 )

FROM Z-SC0RE TABLE

= 1 - ( 0.25804 + 0.49752 )

= 1 - 0.75556

p( 2.1 < X < 2.4 ) = 0.2444

Therefore, the probability that the sample mean is greater than 2.1 but less than 2.4 is 0.2444

You may not know this, but you are home to a colony of bacteria. You may also not know it, but the health and happiness of that colony of bacteria have a direct effect on your own health and happiness. In short, if we are what we eat, then we may need to make bacteria part of our balanced breakfast.

Microbes are single-celled organisms. They are literally everywhere. Microbes are in the air we breathe, on the surfaces of everything we touch, and inside our bodies. Microbes can be bacteria, fungi, protozoa, or viruses.

A few years ago, scientists began studying the microbial life of our stomachs. Called The American Gut project, this study aims to understand the life of the bacteria that live in our digestive system. According to an article in the New York Times by Michael Pollan, the goal is to gather information on the types and amounts of bacteria in the human gut. Scientists want to describe what a normal healthy microbe and human relationship should look like inside our digestive system. While the research is still in the very early stages, scientists have learned the following:

The strongest and healthiest microbe systems are those with a lot of variety.
The guts of Americans have much less variety than the guts of other populations.
Diets that include a lot of processed foods support less variation in bacteria.
Studying the makeup of our individual bacteria communities will help scientists get a better idea of which bacteria help human bodies. We used to think that bacteria in our bodies were invaders. This new research suggests that bacteria are part of the protective army that keeps us healthy. In fact, our bodies have a hard time recovering from medicines like antibiotics because they disrupt the balance of helpful bacteria. It seems clear from the early evidence that living with bacteria helps us resist invasion from things that make us sick.

Scientists have also learned that microbes might help our guts do things like process vitamins and important nutrients. Some microbes may help us deal with stress, or adapt to changes. Furthermore, there may come a time—in your lifetime—when illness is treated not with antibiotics, but with extra-special microbes that help us defend our bodies from illness.

Based on "A Brief Study of Guts," which best summarizes the goal of new research into bacteria and microbes?
A. To collect a wide variety of microbes in all mammals including humans
B. To find ways to increase our intake of helpful microbes
C. To find evidence to decrease the use of antibacterial soap
D. To understand how microbes populate the human body and what benefit they provide
