Answer:
I assume the answer would be that f(x) = 6(x) increases over the interval x = 3 to x = 4
Step-by-step explanation:
6 x 3 is 18 and 6 x 4 is 24, so over the interval x = 3 to x = 4 f(x) would increase.
A spinner has five equal sectors colored red, yellow, green, blue, orange. What is the
probability of landing on a yellow first and then on a blue sector after two consecutive
spins?
Answer: 5/25
5/50
Step-by-step explanation: If each part has 5 sections then it equals to 25 so you have a 5 out of 25 chance of getting it, The second time I added 25 twice since it says your spinning it twice, but you still only have 5 sections so you would have 5 out of 50
The calculated probability is 4 percent.
The student's question involves calculating the probability of two independent events occurring in sequence. Since each sector on the spinner is equal, the probability of landing on yellow for the first spin is 1 out of 5 or 0.2. Similarly, the probability of landing on blue for the second spin is also 1 out of 5 or 0.2.
Since these are independent events, their probabilities are multiplied to find the combined probability. Therefore, the probability of landing on yellow first and then on blue for the second spin is 0.2 * 0.2 = 0.04. This means there is a 4 percent chance of this outcome occurring.

The fanumber of lowers is 14:6. total
The ratio of white flowers to the total
number of flowers is 4:6.
DRAG AND
Container 1: 18 flowers (6 pink + 12 white)
Container 2: 9 flowers (3 pink + 6 white)
Container 3: 15 flowers (10 white + 5 pink)
Container 1:
4 out of 6 flowers are pink, meaning 2 are white.To maintain the ratio, scale up the total number of flowers by a factor of 3 (6 / 2).Therefore, you need 18 flowers in Container 1 (6 pink + 12 white).Container 2:
1/3 of the flowers are pink, so 2/3 are white.Let x be the total number of flowers.Pink flowers: 1/3 * xWhite flowers: 2/3 * xSince the total number of flowers is x, we have 1/3 * x + 2/3 * x = x.Solving for x, we get x = 9 flowers (3 pink + 6 white).Container 3:
The ratio of white flowers to the total number of flowers is 4:6, meaning 2 parts are white and 3 parts are total.Let y be the total number of flowers.White flowers: 2/3 * yTotal flowers: ySince the total number of flowers is y, we have 2/3 * y = y.Solving for y, we get y = 15 flowers (10 white + 5 pink).What is the size of the sample space?

The graph of f "(x) is continuous and decreasing with an x-intercept at x = 0. Which of the following statements is true?
The graph of f has a relative maximum at x = 0.
The graph of f has a relative minimum at x = 0.
The graph of f has an inflection point at x = 0.
The graph of f has an x-intercept at x = 0.
Thank you in advance!
Answer:
The graph of f has an inflection point at x = 0.
Step-by-step explanation:
An inflection point occurs when the second derivative changes signs. Since f"(x) is decreasing and has an x-intercept at 0, it changes signs from + to -, so there is an inflection point at x = 0.
The statements "The graph of f has an inflection point at x = 0." is true
X-interceptThe meaning of X-INTERCEPT is the x-coordinate of a point where a line, curve, or surface intersects the x-axis.
How to solve this problem?F''(x) tells you whether the function is concave up, down, or where it's inflection points are.F"(x)>0 tells you it's concave up.F"(x)<0 tells you it's concave down.F"(x)=0 tells you there's a possible point of inflection at xSince this function is continuous and decreasing, we can assume that before it intercepts x at 0, it is concave up and after it intercepts, it continues to decrease which makes it concave down. Since F"(x)=0 & there is a change in sign, the statement 'The graph of f has an inflection point at x = 0." is true.From above reasons we can say that the statement "The graph of f has an x-intercept at x = 0." is true

Determine the solution to the system of equations below.
x - 3y = 1
3x-5y = 11
Final answer:
To solve the system of equations, use the method of substitution. Solve one equation for one variable and substitute the value in the other equation. Simplify and solve for the variable, then find the value of the other variable. The solution to the system is x = 7 and y = 2.
Explanation:
To determine the solution to the system of equations, we can use the method of substitution or elimination. Let's use the method of substitution.
Step 1: Solve one equation for one variable
From the first equation, we can isolate x: x = 1 + 3y
Step 2: Substitute the value of the variable in the other equation
Substitute x = 1 + 3y into the second equation: 3(1 + 3y) - 5y = 11
Step 3: Simplify and solve for y
Expand the equation and simplify: 3 + 9y - 5y = 11
Combine like terms: 9y - 5y = 11 - 3
Simplify: 4y = 8
Solve for y: y = 2
Step 4: Find the value of the other variable
Substitute the value of y into the first equation: x - 3(2) = 1
Simplify and solve for x: x - 6 = 1
x = 7
Therefore, the solution to the system of equations is x = 7 and y = 2.

What are all kinds of triangle
A triangle is a three-sided two-dimensional shape that can be classified based on side lengths and angle measurements. There are various types of triangles, including equilateral, isosceles, scalene, acute, right, obtuse, equiangular, and right-angled isosceles triangles.
Explanation:A triangle is a three-sided two-dimensional shape. It is a polygon, which is a closed figure with straight sides. Triangles can be classified based on their side lengths, such as equilateral (all sides are equal), isosceles (two sides are equal), and scalene (no sides are equal). They can also be classified based on their angle measurements, such as acute (all angles are less than 90 degrees), right (one angle is 90 degrees), and obtuse (one angle is greater than 90 degrees). Additionally, there are special types of triangles like equiangular triangles (all angles are equal) and right-angled isosceles triangles (one angle is 90 degrees and two sides are equal).

Is x = 0 a valid potential solution to the equation log(x + 7) + log(x − 3) = 17? Question 9 options: A) No, because it isn't possible to take the logarithm of zero: log(0). B) No, because when x = 0, the second term is log(− 3), and it's impossible to take the logarithm of a negative number. C) Yes, logarithms are valid for any integer. D) No, because 17 isn't divisible by 7 or 3.
Answer:
its B
Step-by-step explanation:
No, x = 0 is not a valid solution for log(x + 7) + log(x − 3) = 17 .
Given,
log(x + 7) + log(x − 3) = 17
Here,
Substitute the value of x in the equation,
log(7) + log(-3) = 17
So,
log(-3) is not a valid number and thus its value does not exist .
Thus the equation can not be equated to 17 .
Hence option B is correct .

Tom saves 35% of his salary . Jerry spends 3/5 of his salary and saves rthe rest of his salary work out who saves the most money each month you must show your working.
Final answer:
Jerry saves more money each month than Tom. Tom saves 35% of his salary, whereas Jerry spends 3/5 and saves the remainder, which is 2/5 of his salary. Assuming equal salaries, Jerry's savings are greater.
Explanation:
The question is asking us to compare how much Tom and Jerry save from their salaries. Let's assume each of them earns the same amount of salary, say for example $1000 (this figure is just for simplicity and can represent any currency or amount).
Tom saves 35% of his $1000 salary, which is 0.35 * $1000 = $350.
Jerry spends 3/5 of his salary, which is 3/5 * $1000 = $600. Therefore, he saves 2/5 of his salary because 1 - 3/5 = 2/5. So Jerry saves 2/5 * $1000 = $400.
Comparing the two, Jerry saves more each month since $400 (Jerry's savings) is greater than $350 (Tom's savings).

A rectangle has an area of (x - 17x + 72) square units. Since the area of a rectangle is determined using the formula, A =
kw, what could be the length and width of the rectangle?
length = (x - 8) units and width = (x - 9) units
length = (x + 9) units and width = (x + 8) units
length = (x-6) units and width= (x - 12) units
length = (x + 12) units and width = (x + 6) units
Answer:
Step-by-step explanation:
x² - 17x + 72 = 0
Sum = -17
Product = 72
Factor = 8 , 9
x² - 17x + 72 = 0
x² - 8x -9x + (-8)*(-9) = 0
x(x - 8) -9(x -8) = 0
(x - 8 ) (x - 9) = 0
Length = (x - 8) units
Width = (x - 9) units
SAT verbal scores are normally
distributed with a mean of 450
and a standard deviation of 120.
Determine what percent of the
scores lie between 450 and 570.
Answer:
The percentage of the scores lying between 450 and 750 is 49.4%
Step-by-step explanation:
In this question, we are simply asked to calculate the percentage of the scores lying between a particular range.
The first thing to do here is to calculate the z score of both scores
Mathematically, z score = (x - mean)/SD
for score 450, we have ; z = (450-450)/120 = 0/120 = 0
For score 750, we have z = (750-450)/120 =
2.5
Now, we move on to calculate the probability before turning it into a percentage.
The supposed probability we are to calculate is as follows;
P(450 < x < 750) or P(0 < z < 2.5)
Using standard score table, P = 0.49379
The percentage is thus 49.4%
