Answer:
The first set is a solution, the second is not.
Step-by-step explanation:
Testing by filling in the numbers into the equation:
(1, 1.5): x=1, y=1.5
⇒ 1.5 =? [tex]\frac{1}{4}[/tex] · 1 + [tex]\frac{5}{4}[/tex]
⇒ 1.5 =? [tex]\frac{1}{4}[/tex] + [tex]\frac{5}{4}[/tex]
⇒ 1.5 =? [tex]\frac{6}{4}[/tex]
⇒ 1.5 =? 1.5 ⇒ Correct: is indeed solution to the equation
(12, 4): x=12, y=4
⇒ 4 =? [tex]\frac{1}{4}[/tex] · 12 + [tex]\frac{5}{4}[/tex]
⇒ 4 =? [tex]\frac{12}{4}[/tex] + [tex]\frac{5}{4}[/tex]
⇒ 4 =? [tex]\frac{17}{4}[/tex] ⇒ Incorrect: this is not a solution for the equation
Ana is a teacher who plays a review game with her class. The game involves writing each student's name on
an identical slip of paper and selecting students at random. Here's the makeup of her class:
Grade
9th 10th 11th
Number of students
12. 9. 7.
Suppose that Ana picks a name, replaces it, and picks a name again.
What is the probability that NEITHER of the students selected are
9th graders?
Round your answer to two decimal places.
Answer:
P(Neither 9th grade)=16/28*16/28=16/28*16/28=(16/28)^2=256/784≈0.3265
Answer:
The probability that neither of the students selected are 9th graders is about 0.33.
Step-by-step explanation:
Pls give brainliest
Probabilities are used to determine the chances of events
The probability that neither of the students is a 9th grader is 0.33
From the table, the number of students that are not 9th graders are:
[tex]N9 =9 + 7[/tex]
[tex]N9 =16[/tex]
The total number of students is:
[tex]Total =12 + 9 + 7[/tex]
[tex]Total =28[/tex]
The probability that neither of the students is a 9th grader is calculated as follows
[tex]P =P(N9) \times P(N9)[/tex]
So, we have:
[tex]P =\frac{16}{28} \times \frac{16}{28}[/tex]
Multiply
[tex]P =\frac{256}{784}[/tex]
Divide and approximate
[tex]P =0.33[/tex]
Hence, the probability that neither of the students is a 9th grader is 0.33

[tex]\sf 78-2x=87-3x[/tex]
Answer:
x = 9
Step-by-step explanation:
78 - 2x = 87 - 3x
3x - 2x = 87 - 78
x = 9
x = 9
Step-by-step explanation:
=> 78-2x= 87 -3x
=> 78-87=-3x+2x
=> -9 = -x

Find the equation of the line that passes through (-3,1) and is parallel to y = 1 − 2 x . Leave your answer in the form y = m x + c
Answer:
y = - 3x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x + y - 1 = 0 ( subtract 3x - 1 from both sides )
y = - 3x + 1 ← in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, thus
y = - 3x + c ← is the partial equation
To find c substitute (1, 4) into the partial equation
4 = - 3 + c ⇒ c = 4 + 3 = 7
y = - 3x + 7 ← equation of line in form y = mx + c

City A and City B had two different temperatures on a particular day. On that day, four times the temperature of City A was 8° C more than three times the temperature of City B. The temperature of City A minus twice the temperature of City B was −3° C. The following system of equations models this scenario:
4x = 8 + 3y
x − 2y = −3
What was the temperature of City A and City B on that day?
City A was 5° C, and City B was 4° C.
City A was 3° C, and City B was −1° C.

Nathan earned $105.70 at his job when he worked for 7 hours. What was his hourly wage, in dollars per hour?
Sandy worked extremely hard at her job and earned a large bonus at the end of the year. She decided to give her children 2/5 of the money and her grandchildren 1/4 of her bonus. How much of her bonus did she keep for herself?
Answer:
7/20 of her bonus
Step-by-step explanation:
Solution:
She gives her children 2/5 of her bonus and grandchildren 1/4 of her bonus.
= 1 - 2/5 - 1/4
= 1 - 8/20 - 5/20
= 1 -13/20

The product of 7 and a number is greater than 42. If the number is a whole number less than 10 , what could the number be?
Answer:
8 or 9
Step-by-step explanation:
Your primary equation that they gave you is ?b and has to be greater than ?a 7 x ?a =42
So your answer to ?a is 7 because 7 x 7 =42 therefore your answer to ?b has to be 8 or above.
the next part of your problem states that it is a whole number UNDER 10.... this limits your possible answer to either 8 or 9.

in 2012, the general social survey included a question that asked participants how many hours they worked a week. do males work more hours at a job than females? would this be an example of independent or dependent samples?
Using sampling concepts, it is found that this is an example of independent samples.
For dependent samples, there is a paired measurement for one set of items.For independent samples, separate measurements are made on two different sets, that is, the value on one sample reveal no information about the values on the other sample.In this problem, there are two samples, the sample composed of male workers and the one composed of female workers, and separate measurements are taken, hence, it is an independent sample.

The function for this situation is f(x) = -0.02x + 11.9, where x represents miles and f(x) represents the amount of fuel remaining. What is the rate of change for this scenario?
Answer:
-0.02 gallons per mile
Step-by-step explanation:
You're in luck. The fuel consumption of the car is linear, and the slope - ie, the coefficent of the x term gives you the rate of change. In this case, it's -0.02 gallons per mile.
