3. Austin solved the equation as shown below. Which describes the error
that Austin made in his work?
Austin's Work:
-3 + 7x - 9 + 8x = 54
15x - 6 = 54
15x = 60
x = 4
A. Austin did not combine 7x and 8x correctly.
B. Austin did not combine -3 and -9 correctly.
C. Austin did not divide correctly
D. Austin did not make an error in his work.

Answers

Answer:

B. he didn't combine -3 and -9 correctly

The error that Austin made in his work is  Austin did not combine -3 and -9 correctly.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given that  solved the equation -3 + 7x - 9 + 8x = 54 as shown below.

-3 + 7x - 9 + 8x = 54

15x - 6 = 54

15x = 60

x = 4

We need to check where did Austins has done wrong.

-3 + 7x - 9 + 8x = 54

15x-12=54

For Austin while combining -3 and -9 he got -6 which is wrong.

So Austin did not combine -3 and -9 correctly.

Hence, the error that Austin made in his work is  Austin did not combine -3 and -9 correctly.

What is 9/10 divided by 3/4?

Answers

Answer:

6/5

Step-by-step explanation:

hi! when dividing fractions, we use the KCF rule, which stands for keep,change,flip. we keep the first fraction the same, change the division symbol to multiplication, and flip the second fraction to its reciprocal. therefore, we now have:

9/10 * 4/3

now, we can multiply the numerators and denominators.

36/30

we can simplify this.

Step-by-step explanation:

Assume you have applied for two scholarships, a Merit scholarship (M) and an Athletic scholarship (A). The probability that you receive an Athletic scholarship is 0.18. The probability of receiving both scholarships is 0.11. The probability of getting at least one of the scholarships is 0.3. Let M denote the event that you will receive a Merit scholarship. Let A denote the event that you will receive an Athletic scholarship. Answer questions 11-15. What is the probability that you will receive a Merit scholarship

Answers

Answer:

The probability of obtaining a Merit Scholarship = 0.23

Step-by-step explanation:

From the given information:

The probability of obtaining a merit scholarship P(A) = 0.18

The probability of obtaining both P(A ∩ M) = 0.11

The probability of getting at least one P(A ∪ M)  = 0.3

The objective is to determine the probability of obtaining a Merit Scholarship.

So, as given:

if M represents Merit Scholarship and A represent Athletic Scholarship,

the probability of obtaining a Merit Scholarship is as follows;

P(M) = P(A ∪ M) + P(A ∩ M) - P(A)

P(M) = 0.3 + 0.11 - 0.18 = 0.23

P(M) = 0.23

A drag racer accelerated from 0 m/s to 200 m/s in 5 s.what was the acceleration

Answers

Answer:

40 m/s/s.

Step-by-step explanation:

Acceleration = velocity / time

= 200 / 5

= 40 m/s/s.

Answer:

a = 40m\s^2

Step-by-step explanation:

acceleration is the change of velocity in a certain time interval, which means that it is equal to ( V final - V initial ) \ t

so acceleration here is ( 200 - 0 ) \ 5

which is equal to: 40 m\s^2 and that means that the racer is speeding up by 40 meters each second

(a) Coordinates:

C (9, 6)

Triangle A to B has a change of +3 in x values, but Triangle B to C has a change of +6 values so each triangle doesn’t have the same changes in x values.

Triangle A to B has a change of +2 in y values, Triangle B to C has a change of +4 values so each triangle doesn’t have same change in values.

Triangle A to B change in y over change in x = 2/3, Triangle B to C change in y over change in x = 4/6, both have decimal values of 0.66. Therefore, each triangles has the same ratio of change in y over change in x.

Write a quadratic function f whose zeros are 8 and -3.

Answer:

f(x) = x² - 5x - 24

Step-by-step explanation:

Step 1: Define

Roots/zeros = 8, -3

Step 2: Rewrite

x = 8, -3

Step 3: Write quadratic function

Set zeros into factored binomials: (x + 3)(x - 8)Expand: x² - 8x + 3x - 24Combine like terms: x² - 5x - 24

Answer:

f(x) = x^2 - 5x - 24.

Step-by-step explanation:

In factor form that would be:

f(x) = (x - 8)(x + 3)

f(x) = x(x + 3) - 8(x + 3)

= x^2 + 3x - 8x - 24

f(x) = x^2 - 5x - 24.

Does a linear relation exist between age and HDL​ cholesterol? A. There appears to be a positive linear association because r is positive and greater than the critical value. B. There is little or no evidence of a linear association because r is positive and greater than the critical value. C. There appears to be a negative linear association because r is negative and less than the negative critical value. D. There is little or no evidence of a linear association because the absolute value of r is less than the critical value. More

Answers

Answer:

The correct answer is - option D. There is little or no evidence of a linear association because the absolute value of r is less than the critical value.

Step-by-step explanation:

Given:

Age Cholesterol

49 55

27 45

52 40

38 57

44 28

The linear correlation coefficient between age and HDL cholesterol can be computed by the=

r = Cov (X, Y)/ δx.δy

=v∑XY /√∑X2. ∑Y2

rv=  negative 0.192

The absolute value of r is less than the critical value so there is no or very little evidence of linear association.

Let them come to Berlin.Freedom has many difficulties and democracy is not perfect. But we have never had to put a wall up to keep our people into prevent them from leaving us.While the wall is the most obvious and vivid demonstration of the failures of the Communist systemfor all the world to seewe take no satisfaction in it; for it is, as your Mayor has said, an offense not only against history but an offense against humanity, separating families, dividing husbands and wives and brothers and sisters, and dividing a people who wish to be joined together.What is true of this city is true of Germany: real, lasting peace in Europe can never be assured as long as one German out of four is denied the elementary right of free men, and that is to make a free choice. In 18 years of peace and good faith, this generation of Germans has earned the right to be free, including the right to unite their families and their nation in lasting peace, with good will to all people.Freedom is indivisible, and when one man is enslaved, all are not free. When all are free, then we can look forward to that day when this city will be joined as one and this country and this great Continent of Europe in a peaceful and hopeful globe. When that day finally comes, as it will, the people of West Berlin can take sober satisfaction in the fact that they were in the front lines for almost two decades.All free men, wherever they may live, are citizens of Berlin.And, therefore, as a free man, I take pride in the words "Ich bin ein Berliner."What is Kennedys purpose in including references to the division of families in his speech?to appeal to his audiences logicto make an emotional appeal to his audienceto show his audience where communism has succeededto boost morale and confidence among his audience WhatWhat does the Columbia river and its tributaries provide for the people of Washington HELP ME ASAPPP.
