Question 1 of 10 Diana invested $3000 in a savings account for 3 years. She earned $450 in interest over that time period. What interest rate did she earn? Use the formula I=Prt to find your answer, where I is interest, P is principal, r is rate and t is time. Enter your solution in decimal form rounded to the nearest hundredth. For example, if your solution is 12%, you would enter 0.12
Hey there!!
The question states that a sum is invested which is $3000 and hence, this would be counted as the principle amount or the principle sum.
The term given is 3 years, which gives us the idea that this interest is being counted or being active for 3 years.
She ( Diana ) earned the sum $450 at the end of three years. This means, the simple interest is $450.
Never get confused with the principle amount, principle sum and interest.
Principle amount = Principle sum + The interest.
Formula given :
I = prt
'p' is denoted as the principle sum, r is the rate and the t is the term or the number of years.
Now, plugging in all the values :
... 450 = 3000×r×3
... 450 = 9000×r
... r = 450 / 9000
... r = 0.05
... r = 5%
As we need the answer in the decimal form, the answer would be 0.05
Hope my answer helps!!

Use the two points (4,92) and (1,82) from the scatterplot and the slope formula to find the slope of a linear model (regression line), rounded to three decimal places. Show your work. (5 points)
Using the slope and a point from question (a) to write the equation of the linear model in point-slope form? (5 points)
Simplify the equation you wrote in problem (b) into slope-intercept form. Show your work. (5 points)
Answer:
a) The slope is : 3.333
b) [tex](y-92)=3.333(x-4)[/tex]
c) [tex]y=3.333x+78.66[/tex]
Step-by-step explanation:
a) - The formula to calculate the slope is:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
- Use the given points to calculate the slope:
[tex]y_{2}=82\\y_{1}=92\\x_{2}=1\\x_{1}=4[/tex]
[tex]m=\frac{82-92}{1-4}\\m=\frac{10}{3}\\m=3.333[/tex]
b) - The equation of the linear model in point-slope form is:
[tex](y-y_{1})=m(x-x_{1})[/tex]
Where [tex]m[/tex] is the slope and [tex]x_{1},y_{1}[/tex] are the coordinates of a point.
- Substitute values:
[tex](y-92)=3.333(x-4)[/tex]
c) - The equation of the linear model in slope-intercept form is:
[tex]y=mx+b[/tex]
Where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.
- Let's find [tex]b[/tex]. Use one of the points given in the problem to solve for [tex]b[/tex]:
[tex]92=3.333(4)+b\\b=92-13.332\\b=78.66[/tex]
- Therefore, the equation is:
[tex]y=3.333x+78.66[/tex]

im terrible with graphs help me out...but explain it cuz im a math inclined typa person sooo.......idek just help i guess?
Answer:
14. The correct option is 2.
13. The correct option is 4.
Step-by-step explanation:
14.
The given function is
[tex]f(x)=4|x|[/tex]
The function is non-negative for all values of x. So, the function opens in upward direction.
The function uis in the form of
[tex]f(x)=k|x|[/tex]
Where, a is vertical stretch factor or compress factor.
If k>1, then it represent vertical stretch and if 0<k<1, then it represent vertical compression.
Since the value of k is 4, therefore it represents vertical stretch and option 2 is correct.
13.
The given function is
[tex]y=x^3[/tex]
The traslate form of given function is
[tex]y=(x+a)^3+b[/tex]
Where, a represents the horizontal shift and b represents the vertical shift.
If a>0, then the graph shifts left side by a units and if a<0, then the graph shifts right side by a units.
If b>0, then the graph shifts upward by b units and if b<0, then the graph shifts downward by b units.
Since the graph shifts vertically 5 units down and horizontally 4 units left, therefore the value of a is 4 and value of b is -5. The required equation is
[tex]y=(x+4)^3-5[/tex]
Therefore option 4 is correct.
What number needs to be added to both sides of the equation to complete the square? X^2−7x=5 Enter your answers in the boxes.
To complete the square for the equation x²-7x = 5, you need to add 12.25 to both sides of the equation, leading to the equation (x - 3.5)² = 17.25.
Explanation:To complete the square in the equation x²-7x = 5, we will need to find a term (b) to add to both sides where b is one-half of the number being subtracted from x² (-7), squared.
First, we will take half of 7 which equals 3.5. Squaring 3.5, we get 12.25. Therefore, we add 12.25 on either side to complete the square.
The equation then becomes x² - 7x + 12.25 = 5 + 12.25, which simplifies to (x - 3.5)² = 17.25. This represents a completed square.

To complete the square for the equation [tex]x^2-7x=5[/tex], you need to add 12.25 to both sides. This forms a perfect square trinomial (x - 3.5)² on the left side of the equation and results in the number 17.25 on the right side.
Explanation:The provided equation is a quadratic equation (it's in the form of ax² + bx + c = 0), and you're asked to complete the square.
In order to complete the square, you take half of the coefficient of the 'x' term (which is -7 in this case), square it and add it to both sides of the equation. So, half of -7 is -3.5, and -3.5² equals 12.25.
Therefore, adding 12.25 to both sides of the equation completes the square and forms a perfect square trinomial on the left:
[tex]x^2 - 7x + 12.25 = 5 + 12.25[/tex]
Which simplifies to:
[tex](x - 3.5)^2 = 17.25[/tex]

Kendall is buying a home for 119,000 she is making a 12% down payment and financing the rest with 20-year loan at 4.5% interest what is her monthly mortgage payment ?
662.46 is your answer
The required Kendall's monthly mortgage payment is $662.14.
What is interest?Simple interest is defined as the percentage of earnings on the lending for a period of time.
Here,
Kendall's down payment is 12% of $119,000, which is:
0.12 * $119,000 = $14,280
So the amount she is financing is:
$119,000 - $14,280 = $104,720
To calculate her monthly mortgage payment, we can use the formula for a fixed-payment loan:
[tex]M = P * (r / (1 - (1 + r)^{-n}))[/tex]
First, we need to calculate the monthly interest rate. The annual interest rate is 4.5%, so the monthly interest rate is:
4.5% / 12 = 0.375%
Next, we need to calculate the total number of monthly payments. Kendall has a 20-year loan, which is:
20 years * 12 months/year = 240 months
Now we can plug in the values and solve for M:
[tex]M = $104,720 * (0.00375 / (1 - (1 + 0.00375)^{-240}))[/tex]
M = $662.14
So Kendall's monthly mortgage payment is $662.14.

Uan earns $11 per hour and works at most 30 hours per week. Identify the independent and dependent quantity in the situation, and find reasonable domain and range values. amount of money earned; hours worked; $0 to $330; 0 to 30 amount of money earned; hours worked; 0 to 30; $0 to $330 hours worked; amount of money earned; $0 to $330; 0 to 30 hours worked; amount of money earned; 0 to 30; $0 to $330
Answer:
hours worked; amount of money earned; 0 to 30; $0 to $330
Step-by-step explanation:
Let
y ----> the amount earned per week
x ----> the number of hours worked by week
In this problem
the amount earned per week (variable y) represent the dependent quantity
the number of hours worked by week (variable x) represent the independent quantity
therefore
The domain is the interval -----> [0,30] (the maximum number of hours per week is 30)
The range is the interval -----> [0,11*30] ----> [0,330] (the maximum amount earned per week is $330)
therefore
independent quantity is hours worked
dependent quantity is amount of money earned
domain is 0 to 30
range is $0 to $330
Final answer:
The independent quantity is hours worked and the dependent quantity is the amount of money earned, with a domain of 0 to 30 hours and a range of $0 to $330.
Explanation:
In the given scenario where Uan earns $11 per hour and works at most 30 hours per week, the independent quantity is the hours worked, and the dependent quantity is the amount of money earned. This is because the money earned depends on the number of hours worked.
The domain represents the possible values of the independent variable, which is the hours worked. In this case, it is reasonable to assume that Uan could work anywhere from 0 to 30 hours per week. Therefore, the domain is 0 to 30 hours.
The range represents the possible values of the dependent variable, which is the amount of money earned. Since Uan earns $11 per hour, working 0 hours would yield $0, and working the maximum of 30 hours would yield $330 (30 hours × $11 per hour). Thus, the range is $0 to $330.
The correct answer to the student's question, based on the information, would be: hours worked; amount of money earned; 0 to 30; $0 to $330.

Andy has won 12 out of the last 24 tennis matches he has played. If he wants to improve his win record to 70%, which equation could he use to determine how many matches he would have to win in a row? A) 12 + x 24 + x = 0.70 B) 24 + x 12 + x = 0.70 C) 0.70 24 + x = 12 + x D) 0.70 12 + x = 24 + x
Answer is A
12+x
____. =0.70
24+x
Answer:
A
Step-by-step explanation:
Currently, Andy has a winning record of 50%.
12 /24 = 0.50
To determine a winning record of 70%: add x matches to 12, x matches to 24, and set equal to 0.70.
12 + x /24 + x = 0.70
x = 16
Therefore, Andy would need to win 16 matches in a row.
Use the graph of the parent function f(x)=√x, to describe the transformation for the graph of g(x)=√x-5
Answer : C
[tex]f(x)= \sqrt{x}[/tex]
[tex]g(x)= \sqrt{x-5}[/tex]
Parent function is f(x). In g(x) 5 is subtracted from x
If any number is added or subtracted from x, then we move left or right
When a number 'a' is added with x then we shift 'a' units to the left
When a number 'a' is subtracted from x then we shift 'a' units to the right
f(x) is our parent function. Here 5 is subtracted from x to get g(x)
For -5, the graph of g(x) is the graph of f(x) shifted right 5 units
the first answer would be C

You work 1.15 hours on your English Homework and 1.75 hours in your math homework. Your science homework takes 1.05 hours less than your math homework. How many more hours do you work on your homework? The answer is 4 but it's saying it's wrong
Answer:
Total time taken for doing home work = 3.6 hours.
Explanation:
Time taken for English home work = 1.15 hours.
Time taken for Mathematics home work = 1.75 hours.
Time taken for Science home work = Time taken for Mathematics home work - 1.05 hours = 1.75 - 1.05 = 0.7 hours
Total time taken for doing home work = 1.15 + 1.75 + 0.7 = 3.6 hours.
So the answer is not 4 hours, it is 3.6 hours, that is why it is showing it as wrong.
