Answer:
2/3
Step-by-step explanation:
because 1 1/2 x 2/3 = 2 1/4
Answer:
1 1/2 = 3/2
2 1/4 = 9/4
3/2 divided by 9/4 = 3/2 multiplied by 4/9 = 2/3
EXPLANATION : when we have 2 fractions and we have to divide them , we have to reverse the fraction that we are dividing by and multiply it. sometimes we can simplify the fractions , sometimes we can't. for example , with 3/2 multiplied by 4/9 we simplified 3 and 9 and the 2 and the 4 which left us with 1/1 ( 1 ) multiplied by 2/3 , which gave us the answer 2/3 .

How to define a linear function?The slope-intercept representation of a linear function is given by the equation presented as follows:
y = mx + b
The coefficients of the function and their meaning are described as follows:
m is the slope of the function, representing the change in the output variable y when the input variable x is increased by one.b is the y-intercept of the function, which is the initial value of the function, i.e., the numeric value of the function when the input variable x assumes a value of 0. On a graph, it is the value of y when the graph of the function crosses the y-axis.The slope and the intercept for the function in this problem are given as follows:
Slope of -1.22, meaning that for an increase of one degree Fahrenheit, the predicted decrease in the cost is of $1.22.Intercept of 96.2, meaning that the predicted heating cost for a month with temperature of 0 ºF is of $96.20.Hence, the predicted cost for a month with temperature of 25ºF is given as follows:
y = -1.22(25) + 96.20 = $65.70.

A new physical therapy is being tested in an experimental setting to see if the new methods reduce the recovery time for patients who recently underwent surgery for a torn ACL, a ligament in your knee. To do this, the researchers in the study first performed intake on participants by observing their Body Mass Index (BMI) and had them take a survey to describe their diet and their exercise habits.
Then, the participants were split into three groups: the first group received no physical therapy, the second group received traditional physical therapy, and the third group received the new experimental physical therapy.
The group which receives no physical therapy would best be described as which of the following?
Explanatory Variable
Response Group
Control Group
Experimental Unit
Answer: The group which receives no physical therapy would best be described as the Control Group.
In an experimental study, the control group is a group of participants who do not receive the treatment being tested. They are used as a basis for comparison to evaluate the effectiveness of the treatment. In this case, the researchers are testing whether the new physical therapy reduces the recovery time for patients who underwent surgery for a torn ACL. The control group allows the researchers to compare the recovery time of patients who received no physical therapy to those who received either traditional or experimental physical therapy.

Answer:
790,000
Step-by-step explanation:
The 5 represents the number by itself so it would be
10x10x10x10x10=100,000
7.9x100,000=790,000
Step-by-step explanation:
if you multiply something by 10 = 10¹, you move the decimal point 1 position to the right (and fill up with a 0, if necessary).
if you multiply something by 100 = 10², you move the decimal point 2 positions to the right (and fill up with 0s as needed).
if you multiply something by 1000 = 10³, you move the decimal point 3 positions to the right (and fill up with 0s as needed).
...
you see the pattern ?
so, when multiplying by 10⁵ (100,000) we shift the decimal point 5 pairings to the right and fill up with 0s as needed.
therefore,
7.9 × 10⁵ = 790,000.-

The table below shows the change in price of a particular share on the stock market.
Daily share price changes
Day Daily change (In dollars)
1 +2.75
2 -4.375
3 +0.875
4 -2.5
Part A: By how did the price of the share change from the start of day 1 to the end of day 4?
Part B: At the end of day 4 the price of the share is $102.85. What was the price of the share at the start of day 1?
Answer:
Part-a: The price of the share decreased by $3.25 from the start of day 1 to the end of day 4.
Part-b: The price of the share at the start of day 1 was $106.10.
Step-by-step explanation:
Part A: To calculate the change in price from the start of day 1 to the end of day 4, we need to add up all the daily changes. The daily changes given are:
Day 1: +2.75
Day 2: -4.375
Day 3: +0.875
Day 4: -2.5
Adding these values together:
Change = 2.75 - 4.375 + 0.875 - 2.5 = -3.25
The price of the share decreased by $3.25 from the start of day 1 to the end of day 4.
Part B: To find the price of the share at the start of day 1, we need to subtract the total change from the given price at the end of day 4.
Price at the end of day 4 = $102.85
Total change = -3.25
Price at the start of day 1 = Price at the end of day 4 - Total change
= $102.85 - (-3.25)
= $102.85 + 3.25
= $106.10
Therefore, the price of the share at the start of day 1 was $106.10.

What is 0.65 expressed as a fraction in simplest form?
What is 2.¯5 expressed as a fraction in simplest form?
What is 1.0¯24 expressed as a fraction in simplest form?
Answer:
Part A)
Part B)
Part C)
Answer:
Step 1: Write down the decimal as a fraction with the decimal number as the numerator and 1 as the denominator.
Step 2: Multiply both the numerator and denominator by 10^n, where n is the number of digits after the decimal point.
Step 3: Simplify the resulting fraction.
Using these steps, we can convert the given decimal numbers to fractions:
0.65
Step 1: 0.65 = 65/100
Step 2: Multiply numerator and denominator by 10 to get rid of the decimal point: 65/100 = 650/1000
Step 3: Simplify by dividing numerator and denominator by their greatest common factor of 50: 650/1000 = 13/20
Therefore, 0.65 expressed as a fraction in simplest form is 13/20.
2.¯5
To handle repeating decimal numbers, we can use the following method:
Step 1: Let x be the repeating decimal number.
Step 2: Multiply both sides of x by 10^n, where n is the number of digits in the repeating part of the decimal number.
Step 3: Subtract the original number from the number obtained in step 2 to eliminate the repeating part.
Step 4: Solve for x by dividing both sides of the equation obtained in step 3 by an appropriate factor.
Step 1: Let x = 2.¯5
Step 2: Multiply both sides by 10: 10x = 25.¯5
Step 3: Subtract the original equation from step 1: 10x - x = 25.¯5 - 2.¯5
Simplifying: 9x = 23
Step 4: Solve for x by dividing both sides by 9: x = 23/9
Therefore, 2.¯5 expressed as a fraction in simplest form is 23/9.
1.0¯24
Step 1: Let x = 1.0¯24
Step 2: Multiply both sides by 10^2 to eliminate the repeating part: 100x = 124.¯24
Step 3: Subtract the original equation from step 1: 100x - x = 124.¯24 - 1.0¯24
Simplifying: 99x = 123
Step 4: Solve for x by dividing both sides by 99: x = 123/99
We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor of 3: 123/99 = 41/33.
Therefore, 1.0¯24 expressed as a fraction in simplest form is 41/33.
Step-by-step explanation:
0.65 expressed as a fraction in simplest form is 13/20.
2.5 expressed as a fraction in simplest form is 5/2.
1.024 expressed as a fraction in simplest form is 256/250.
What is the simplified form of the expressions in fraction?0.65 expressed as a fraction in simplest form:
Write the decimal as a fraction by placing it over 1. In this case, 0.65 becomes 0.65/1.
Remove the decimal by multiplying both the numerator and the denominator by a power of 10 that will eliminate the decimal.
In this case, multiplying by 100 will do the trick, so we get (0.65 × 100)/(1 × 100) = 65/100.
Lastly, simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD).
The GCD of 65 and 100 is 5, so dividing both by 5 yields 13/20.
2.5 expressed as a fraction in simplest form:
Write the decimal as a fraction by placing it over 1. In this case, 2.5 becomes 2.5/1.
Remove the decimal by multiplying both the numerator and the denominator by a power of 10 that will eliminate the decimal.
In this case, multiplying by 10 will do the trick, so we get (2.5 × 10)/(1 × 10) = 25/10.
Lastly, simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD).
The GCD of 25 and 10 is 5, so dividing both by 5 yields 5/2.
1.024 expressed as a fraction in simplest form:
Write the decimal as a fraction by placing it over 1. In this case, 1.024 becomes 1.024/1.
Remove the decimal by multiplying both the numerator and the denominator by a power of 10 that will eliminate the decimal.
In this case, multiplying by 1000 will do the trick, so we get (1.024 × 1000)/(1 × 1000) = 1024/1000.
Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD).
The GCD of 1024 and 1000 is 8, so dividing both by 8 yields 128/125.

Which statement is true
Answer: The answer is B
Step-by-step explanation:
The statement which is true include the following: C. function 2 is the only nonlinear function.
What is a linear function?In Mathematics and Geometry, a linear function refers to a type of function whose equation is graphically represented by a straight line on the xy-plane or cartesian coordinate.
This ultimately implies that, a linear function has the same (constant) slope and it is typically used for uniquely mapping an input variable to an output variable, which both increases simultaneously.
In this context, we can logically deduce that function 2 is a quadratic function and as such, it is the only nonlinear function.

Find the 25th term.
2, 10, 18, 26, 34, ...
25th term = [?]
an = a1 + (n - 1)d
Substituting the values
an = 2 + (n - 1)8
We have to find the 25th term n = 25
a25 = 2 + (25 - 1)8
a25 = 2 + (24)8
a25 = 2 + 192
a25 = 194
======================================================
Explanation:
The gap between adjacent terms is 8.
2+8 = 1010+8 = 1818+8 = 2626+8 = 34etcThe long way to get the answer would be to keep adding 8 to each term to generate the next one. You'd need to do this 20 times. There are 5 terms here already, so you need 25-5 = 20 more operations of "add 8".
I don't recommend this option. I recommend the shortcut mentioned in the next section.
--------
The shortcut would be to find the nth term of the arithmetic sequence
[tex]a_1 = 2 = \text{ first term}\\\\d = 8 = \text{ common difference}\\\\a_n = \text{ nth term}\\\\a_n = a_1 + d(n-1)\\\\a_n = 2 + 8(n-1)\\\\[/tex]
As a check, plug n = 1 into that formula to get [tex]a_1 = 2[/tex]. Plug n = 2 to get [tex]a_2 = 10[/tex] and so on. I'll leave this check portion for the student to do.
--------
The last step is to plug n = 25 into that formula to determine the 25th term.
[tex]a_n = 2 + 8(n-1)\\\\a_{25} = 2 + 8(25-1)\\\\a_{25} = 2 + 8(24)\\\\a_{25} = 2 + 192\\\\a_{25} = 194\\\\[/tex]
The final answer is 194-------
Extra section (optional):
We can use a spreadsheet to generate the 25 terms. This is to help check the answer.
