Step-by-step explanation:
[tex]\dfrac{\text{\# of vowels}}{\text{total \# of letters}}[/tex]
1st draw and 2nd draw
[tex]\dfrac{5}{26}[/tex] x [tex]\dfrac{4}{25}[/tex] = [tex]\dfrac{20}{650}[/tex]
[tex]\dfrac{20}{650}\div\dfrac{10}{10}=\dfrac{2}{65}[/tex]
This is dependent because the number of vowels remaining for the 2nd draw is dependent on whether or not a vowel was chosen on the 1st draw.
suppose f(x)=x^2 and g(x)=(1/5x)^2. Which statement best compares the graph of g(x) with the graph of f(x)?
Answer:
g(x) is the image of f(x) after stretched horizontally
by scale factor = 5
Step-by-step explanation:
∵ f(x) = x² ⇒ quadratic function
∵ g(x) = (1/5 x)² ⇒ The image of f(x) after one transformation
* Stretches or compresses horizontally:
It means stretches away from the y-axis
or compresses toward the y-axis
* If f(x) = (ax)² :
∵ |a| > 1 is a compression by factor of 1/a
∵ 0 < |a| < 1 is a stretch by factor of 1/a
∵ x-coordinate of f(x) multiplied by 1/5
∵ 0 < 1/5 < 1
∴ The transformation is ⇒ stretched horizontally
∴ g(x) is the image of f(x) after stretched horizontally
by scale factor = 1 ÷ 1/5 = 5
Which are equivalent to the expression x^1/2 * x^1/2
Answer:
x and see others below
Step-by-step explanation:
To find the equivalent expression, multiply the terms using exponent rules.
Exponent rules state to add the exponent of same bases being multiplied.
[tex]x^{\frac{1}{2}} *x^{\frac{1}{2}} =x^{\frac{1+1}{2}} =x^{\frac{2}{2}} = x^1 = x[/tex]
Each of the parts of the expression are equivalent. The simplified equivalent expression is x.

Use a graph to find x and y values that make both y=-x+3 and y=2x−5 true.
Two lines y = -x + 3 and y = 2x - 5 are graphed to find their intersection, which gives the x and y values that satisfy both equations.
Explanation:To find x and y values that satisfy both equations y = -x + 3 and y = 2x - 5, we need to graph these equations and look for their point of intersection.
Start by plotting the line y = -x + 3. For example, when x=0, y=3 and when y=0, x=3.Next, plot the line y = 2x - 5. Here, when x=0, y=-5 and when y=0, x=2.5.Draw both lines on the same set of axes. The point where they cross is the solution to the system of equations.The intersection represents the x and y values that make both original equations true simultaneously. Use the graph to identify the coordinates of this point for the exact solution.
Out of the choices provided, only [tex]$(-3,5)$[/tex] lies on the intersection of the two lines. Thus the answer is a. [tex]$(-3,5)$[/tex].
Here's a step-by-step solution to find the x and y values that satisfy both equations:
1. Graph the Equations:
Take the first equation, y = -2/3x + 3. This equation is in slope-intercept form (y = mx + b), where m (slope) is -2/3 and b (y-intercept) is 3.
- Plot the y-intercept (3) on the y-axis.
- Since the slope is -2/3, remember "rise over run." So in this case for every 2 positions you move down (because it's negative), you move 3 positions to the right. Plot another point based on this movement.
- Connect these two points with a straight line.
- Repeat the process for the second equation, y = 2x - 5. This equation is also in slope-intercept form with m (slope) as 2 and b (y-intercept) as -5.
- Plot the y-intercept (-5) on the y-axis.
- The slope is 2, so for every 2 positions you move up, you move 1 position to the right. Plot another point based on this movement.
- Connect these two points with a straight line.
2. Find the Intersection Point:
- Observe the graph. The point where the two lines intersect represents the solution where both equations are true simultaneously.
- In this case, the lines intersect at the point (-3, 5).
Verification:
- You can substitute x = -3 and y = 5 in both the original equations and see if they hold true.
- For y = -2/3x + 3, substituting x = -3 gives you y = (-(2/3) [tex]\times[/tex] (-3)) + 3 = 2 + 3 = 5 (which is true).
- For y = 2x - 5, substituting x = -3 gives you y = (2 [tex]\times[/tex] -3) - 5 = -6 - 5 = -11 (which is not true).
Therefore, the solution (x, y) that makes both equations true is (-3, 5). This is the point where the two lines intersect on the graph.
The graph is provided below.

Sam conducted a survey to find out the favorite weekend activity of the students in his middle school. He asked 20 of his classmates. He found out that the favorite weekend activity of his middle school is playing video games because 75% of the students he surveyed liked to play video games. Explain why Sam’s sample may not be valid. Provide 2 or 3 sentences of explanation with facts to support your answer. How could Sam improve his survey to be more representative of his school?
Answer
So, Sam only asked 20 people in his entire middle school. That is a very small fraction of the amount of kids attending that school. He cannot say that video games is 75% of the entire school's favorite weekend activity if he only asked 20 people. To get a better, more valid result, he should ask around 100+ kids.

8^2y+4 = 16^y+1
Answer:
y = -4
Step-by-step explanation:
Assuming the problem is [tex]8^{2y+4}=16^{y+1}[/tex], it would be nice if we could convert both sides of this equation to the same base; that way, we could compare the exponents directly in an equation of their own. Fortunately, 8 and 16 are both powers of 2 -- [tex]2^3[/tex] and [tex]2^4[/tex], we can rewrite the original equation by substituting those in:
[tex](2^3)^{2y+4}=(2^4)^{y+1}[/tex]
When you have an exponent raised to another exponent, you multiply those exponents together, so we can simplify our equation by distributing a 3 in the left exponent and a 4 in the right:
[tex]2^{3\cdot(2y+4)}=2^{4\cdot(y+1)}\\2^{3\cdot2y+3\cdot4}=2^{4\cdot y+4\cdot1}\\2^{6y+12}=2^{4y+4}[/tex]
With both of our bases the same, we can now simply compare their exponents directly to solve for y:
[tex]6y+12=4y+4\\2y=-8\\y=-4[/tex]
Simplify the expression.
4(-8x + 5) – (-33x – 26) =
The simplified expression is x + 46.
To simplify the expression, let's distribute and simplify each term:
4(-8x + 5) - (-33x - 26)
First, distribute 4 into -8x + 5:
= -32x + 20
Then, distribute -1 into -33x - 26:
= -32x + 20 + 33x + 26
Now, combine like terms:
= (-32x + 33x) + (20 + 26)
= 1x + 46
= x + 46
So, the simplified expression is x + 46.

Step-by-step explanation:
Spencer takes out a home improvement loan for 30,000 at an interest rate of 5.5%. How much does he owe, and what is his monthly payment if he chooses the 7-year loan payment plan?
Answer:
Use the simple interest formula: A = P(1 + rt) where P is the Principal amount of money to be invested at an Interest Rate R% per period for t Number of Time Periods.
First, converting R percent to r a decimal
r = R/100 = 5.5%/100 = 0.055 per year.
Solving our equation:
A = 30000(1 + (0.055 × 7)) = 41550
A = $41,550.00
The total amount accrued, principal plus interest, from simple interest on a principal of $30,000.00 at a rate of 5.5% per year for 7 years is $41,550.00.
Step-by-step explanation:
Answer:
11550
Step-by-step explanation:
Formula for calculating simple interest is : Simple Interest=P x R x T/100
Step 1: Identify P,R,T
P: Principal amount-basic amount of the loan (30,000)
R: The interest rate of the loan (5.5%)
T: Time of payment of loan-in years (7 years)
Step 2: Substitute the values
Simple Interest= P x R x T/100
Simple Interest= 30,000 x 5.5 x7
100
Simple Interest= 1155000
100
Simple Interest= 11550
Let's answer the first part of the question: "How much does he owe?"
Step 1: We have calculated simple interest which is 11550.
Step 2: The principal amount has to be paid with the simple interest.
Step 3: Formula- Total money owed= Principal amount + Simple Interest
Total money owed= 30,000 + 11550=41550
Now let's answer the second part of the question: "What is the monthly payment if he chooses the 7-year loan payment plan?"
Step 1: Calculate how many months are there in 7 years. Each year has 12 months therefore 7 years have (7 x 12) 84 months.
Step 2: Divide the total amount that has to be paid by the number of months it has to be paid in.
Monthly payment = Total money owed/ total number of months
Monthly payment = 41550/ 84
Monthly payment = 494.64

Find the circumference of a circle with an area of 201.06 square inches.
Answer: C= 50.2652
Step-by-step explanation:
The circumference of a circle with an area of 201.06 square inches is approximately 50.24 inches, after calculating the radius from the area and applying it to the circumference formula.
Explanation:To find the circumference of a circle when given the area, you'll want to perform a series of mathematical steps. The area of a circle is given by the formula A = πr², and the circumference is given by C = 2πr. You can rearrange the area formula to solve for the radius, r, and then substitute that into the circumference formula.
First, solve for the radius:
A = πr² → r = √(A/π) → r = √(201.06/π).
Once you have r, plug it into the circumference formula:
C = 2πr.
Using a calculator, you'll find the following values:
r = √(201.06/3.14) which is approximately r = 8 inches.Then calculate the circumference: C = 2 × 3.14 × 8 which is approximately C = 50.24 inches.The circumference of a circle with an area of 201.06 square inches is approximately 50.24 inches.
