What is the equation of the line in slope-intercept form?

Answers

Answer:

y = 4/3x + 4

Step-by-step explanation:

y = mx + b is the formula for finding the slope intercept form equation

m = slope

b = y intercept

If you look at points (-3, 0) and (0, 4), you can calculate the slope

You have to go over, from point (-3, 0), 3 times, and up four to get to the point (0, 4)

Slope is change in y over change in x, so, if we look to see where the line crosses the y-axis, or vertical axis, we can see it reach the number four on the y-axis, b = 4

Now, lets create your equation...

y = 4/3x + 4

Is 5/18 a rational number ?

Answers

Answer:

5/18 is a rational number because a rational number is any integer,fraction terminating decimal,or repeating decimal.

5/18 is rational number.

What is Rational Number?

The word "ratio" is where the word "rational" first appeared. Rational numbers are therefore closely tied to the idea of fractions, which stand for ratios. In other terms, a number is a rational number if it can be written as a fraction in which the numerator and denominator are both integers.

Any number of the form p/q, where p and q are integers and q is not equal to 0, is a rational number. The letter Q stands for the set of rational numbers. Look at the following illustration to see what a rational number looks like.

Given:

5/18

For rational we need to first divide the fraction and then check whether the fraction is a decimal or not.

Or if it is a decimal then it is terminating or non terminating

5/18 = 0.2777777777777778

Hence, it is terminating  because rational number is any integer, fraction terminating decimal or repeating decimal.

This month the Middle School Media newspaper has 25 pages. Twenty-five schools order the paper for each of their students. Each of the schools has 25 classrooms with 25 students in each classroom. What expression with an exponent shows the total number of pages in all of the newspapers? Explain how you found the answer. Use words, numbers, and/or pictures to show your work. Write your answers on the paper provided. I will give brainiest to best answer.plz help

Answers

Answer:

The total number of pages in all the newspaper is 390,625 pages

Step-by-step explanation:

The number of pages in the newspaper = 25 pages

The number of schools ordering the newspaper = 25 schools

The number of class rooms in each school = 25 classrooms

The number of students in each classroom = 25 students

Therefore;

The total number of pages in all the newspaper = 25 pages per paper × 25 schools × 25 classroom per school × 25 students per classroom

The total number of pages in all the newspaper = 25 × 25 × 25 × 25 = 25⁴

The total number of pages in all the newspaper = 25⁴ = 390,625 pages

How to compare to decimals?

Comparing decimals involves starting with the digits having the highest place value, just like when comparing other whole numbers. We begin the comparison by putting the provided decimal numbers in a place value table. We move on to the digits in the next place to the right if the digits on the biggest place value match. Up till the digits that are different are reached, we continue comparing digits.

The given decimal number is -0.33.

A) -0.3 is greater than -0.33

B) -3/9 = -0.33

Here, -3/9 is equal to -0.33

C) 1/6 =0.16

Here, 1/6 is greater than -0.33.

La probabilidad de que, al seleccionar una persona, esta guste del basquetbol es de 0,5, la probabilidad de que esta guste del futbol es de 0,7, la probabilidad de seleccionar a alguien que guste de alguno de los dos deportes es del 0,85 ¿Cuál es la probabilidad de seleccionar a una persona que guste de ambos deportes?

Answers

Answer:

En una baraja completa de naipes ingleses (108 naipes), se selecciona un naipe, ¿Cuál es la probabilidad de que esta sea un joker rojo?

Por cada baraja de naipes de 54 cartas hay 1 joker rojo. Si esta baraja tiene 108 cartas, entonces habran 2 joker rojos.

Probabilidad de sacar 1 joker rojo = 2 / 108 = 1 / 54 = 0.185185 = 1.85%

En las votaciones para alcalde de la ciudad "Copito de Nieve" en una de las urnas, la probabilidad de sacar un voto para el candidato A es de 0,3, mientras que la probabilidad de obtener un voto para el alcalde B es de 0,5 ¿Cuál es la probabilidad de seleccionar un voto nulo o blanco?

probabilidad de sacar un voto nulo o blanco = 1 - probabilidad de sacar un voto para el alcalde B - probabilidad de sacar un voto para el candidato A = 1 - 0.5 - 0.3 = 0.2 = 20%

La probabilidad de que, al seleccionar una persona, esta guste del basquetbol es de 0,5, la probabilidad de que esta guste del futbol es de 0,7, la probabilidad de seleccionar a alguien que guste de alguno de los dos deportes es del 0,85 ¿Cuál es la probabilidad de seleccionar a una persona que guste de ambos deportes?

probabilidad que le gusten los dos deportes = probabilidad que le guste el futbol x probabilidad que le guste el basquetbol = 0.5 x 0.7 = 0.35 = 35%

ANSWERS:

-alternate interior
-alternate exterior
-consecutive interior
-consecutive exterior

Answers

Answer:

c. <3 and <6: AE, alternate exterior

d. <9 and <14: CE, consecutive exterior

e. <4 and <7: CI, consecutive interior

f. <2 and <10: CA, corresponding angles

g. <8 and <14: CI, consecutive interior

h. <6 and <11: None

i. <4 and <13: None

j. <4 and <9: AI, alternate interior

Step-by-step explanation:

c. <3 and <6 are alternate angles located outside the parallel lines that are cut across by transversal c. Therefore they are alternate exterior angles.

d. <9 and <14 lie outside the parallel lines that are cut across by transversal d, and they are on the same side of the transversal. Therefore, they are consecutive exterior angles.

e. <4 and <7 lie within the parallel lines that are cut across by transversal c, and they are on the same side of the transversal. Therefore, they are consecutive interior angles.

f. <2 and <10 lie on the same position on each line cut across by the transversal line. Therefore they are corresponding angles

g. <8 and <14 lie on the same side of the transversal and are within the two lines cut across by a transversal. Therefore, they are consecutive interior angles.

h. <6 and <11 has no relationship. The answer is none.

i. <4 and <13 has no relationship. None is the answer.

j. <4 and <9 lie on alternate side of the transversal line and are within the two lines cut across by the transversal line. Therefore, they are alternate interior angles.
