A survey was done with 50 students currently taking Algebra 1 at Laurel Springs School. They were asked which they preferred - English or mathematics? Out of the 50 students, 30 were male. There were 35 students who preferred mathematics and out of those that preferred mathematics, 24 were male. Create a two way relative frequency table for the data. According to the table, would it be safe to assume that females prefer English and males prefer mathematics? Why or why not?
Answers
we can see that a larger proportion of male students preferred mathematics (0.48) compared to female students (0.22), while a larger proportion of female students preferred English (0.18) compared to male students (0.12).
HOW TO SOLVE THE QUESTION?
To create a two-way relative frequency table, we can use the following table:
| English | Mathematics | Total
--------|---------|-------------|-------
Male | x | 24 | 30
Female | y | 11 | 20
--------|---------|-------------|-------
Total | 35 | 35 | 50
Here, x and y represent the number of male and female students who preferred English, respectively.
To calculate the values for x and y, we can use the fact that there were 35 students who preferred mathematics, and 24 of them were male. Therefore, the number of females who preferred mathematics is 35 - 24 = 11. Since there are a total of 20 female students, the number of females who preferred English is 20 - 11 = 9. Similarly, the number of male students who preferred English is 30 - 24 = 6.
To calculate the relative frequencies, we can divide each cell by the total number of students (50). For example, the relative frequency of male students who preferred mathematics is 24/50 = 0.48.
The resulting two-way relative frequency table is as follows:
| English | Mathematics | Total
--------|---------|-------------|-------
Male | 0.12 | 0.48 | 0.60
Female | 0.18 | 0.22 | 0.40
--------|---------|-------------|-------
Total | 0.30 | 0.70 | 1.00
From this table, we can see that a larger proportion of male students preferred mathematics (0.48) compared to female students (0.22), while a larger proportion of female students preferred English (0.18) compared to male students (0.12). However, it would not be safe to assume that all females prefer English and all males prefer mathematics based on this data alone, as there may be individual variations and exceptions to this trend.
It's also important to note that the sample size is relatively small, with only 50 students surveyed, and may not be representative of the larger population. Further research with a larger and more diverse sample size would be needed to make more accurate conclusions about gender-based preferences in this population

Write 762 in the base seven system
Answers
762 base 10 to base 7 is 2136 base 7
What are Base Numbers?
Base Numbers are the number of units, or numbers, we use in our counting system. The most common base number is ten because the digits 0-9 are used in the number system.
And it is a base-7 number system we would only use seven different digits, like 0-6.
How to determine this
By dividing the number 762 base 10 in base 7 until it can no more be divided in base 7.
First divide 762 /7 = 108 remainder 6
108/7 = 15 remainder 3
15/7 = 2 remainder 1
2/7 = 0 remainder 2
Where the remainders arranged in descending is the base system.
So, by arranging from the bottom

If z = x2 + 5x − 3y3,
find the following.
Answers
That the gradient gives the direction of steepest ascent, so the negative of the gradient gives the direction of steepest descent.
To find the slope of the tangent in the positive y-direction to the surface z = 3x + 2y − 4exy at (6, 0, 14), we need to find the partial derivative of z with respect to y and evaluate it at the point (6,0):
∂z/∂y = 2 - 4ex(6)
At (6,0), this becomes:
∂z/∂y = 2 - 4e(36) = -646.158
So the slope of the tangent in the positive y-direction at (6,0,14) is -646.158.
To find the following for z = x2 + 5x − 3y3:
a) The partial derivative of z with respect to x:
∂z/∂x = 2x + 5

The population of American IQ scores are normally distributed with a mean of 101 and a standard deviation of 17. If a random sample of 416 American IQ scores are selected, what sample average score would be the 33rd percentile for all such sample averages?
Answers
In the given problem, using central limit theorem, the sample average score that corresponds to the 33rd percentile of all such sample averages is 100.66.
How to Calculate the Average?To solve this problem, we need to use the central limit theorem, which states that the distribution of sample averages is approximately normal, regardless of the distribution of the population, as long as the sample size is sufficiently large.
The mean of the sample means is equal to the population mean, which is 101. The standard deviation of the sample means, also known as the standard error of the mean, is equal to the population standard deviation divided by the square root of the sample size. In this case, the standard error of the mean is:
SE = 17 / sqrt(416) = 0.831
To find the sample average score that corresponds to the 33rd percentile of all such sample averages, we need to find the z-score that corresponds to the 33rd percentile and then use it to calculate the sample average score.
The z-score corresponding to the 33rd percentile is given by:
z = invNorm(0.33) = -0.439
where "invNorm" is the inverse normal distribution function.
We can use the formula for the z-score of a sample mean:
z = (x - μ) / SE
Rearranging this formula, we get:
x = z * SE + μ
Substituting the values we have, we get:
x = -0.439 * 0.831 + 101 = 100.66
Therefore, the sample average score that corresponds to the 33rd percentile of all such sample averages is 100.66.

Construct a polynomial function with the started properties. Third-degree, with zeros of −3 , − 1 , and 2 , and passes through the point (3,5)
Answers
Step 1: Convert zeros to factors of the polynomial.
If "k" is a zero, then (x-k) is a factor of the polynomial.
The allows us to convert zeros of -3, -1, and 2 into the factors (x+3)(x+1)(x-2).
So right now we have y= (x+3)(x+1)(x-2), but there's a missing piece, the leading coefficient of "a", so really we currently have
y = a · (x+3)(x+1)(x-2)
This is where the point (3,5) comes in. We need to substitute x=3 and y=5 into the equation above to find a.
5 = a · (3+3)(3+1)(3-2)
5 = a · (6)(4)(1)
5 = a · 24
5/24 = a
That's the full function:
f(x) = 5/24 (x+3)(x+1)(x-2)
Answer:
[tex]f(x)=\dfrac{5}{24}x^3+\dfrac{5}{12}x^2-\dfrac{25}{24}x-\dfrac{5}{4}[/tex]
Step-by-step explanation:
The zeros of a polynomial f(x) are the values of x which satisfy f(x) = 0.
If the polynomial function is degree 3 with 3 zeros, in factored form it can be written as f(x) = k(x - r₁)(x - r₂)(x - r₃) where r are the zeros and k ≠ 0.
Substitute the given zeros -3, -1 and 2 into the formula:
[tex]\implies f(x)=k(x-(-3))(x-(-1))(x-2)[/tex]
[tex]\implies f(x)=k(x+3)(x+1)(x-2)[/tex]
To find the value of k, substitute the given point (3, 5) into the function:
[tex]\begin{aligned}\implies f(3)&=5\\k(3+3)(3+1)(3-2)&=5\\k(6)(4)(1)&=5\\24k&=5\\k&=\dfrac{5}{24}\end{aligned}[/tex]
Therefore, the factored form of the polynomial function is:
[tex]\implies f(x)=\dfrac{5}{24}(x+3)(x+1)(x-2)[/tex]
To write in standard form, expand and distribute:
[tex]\implies f(x)=\dfrac{5}{24}(x^2+4x+3)(x-2)[/tex]
[tex]\implies f(x)=\dfrac{5}{24}(x^3+2x^2-5x-6)[/tex]
[tex]\implies f(x)=\dfrac{5}{24}x^3+\dfrac{10}{24}x^2-\dfrac{25}{24}x-\dfrac{30}{24}[/tex]
[tex]\implies f(x)=\dfrac{5}{24}x^3+\dfrac{5}{12}x^2-\dfrac{25}{24}x-\dfrac{5}{4}[/tex]

What is derivative of function?The rate change of the function at a specific point
a) The values of x where the derivative of the function equals zero or does not exist.
f'(x) = -4x + 4
Setting f'(x) equal to zero gives:
-4x + 4 = 0
-4x = -4
x = 1
So the critical number is x = 1.
(b) we need to examine the sign of the derivative on either side of the critical number.
When x < 1, f'(x) is negative, indicating that the function is decreasing.
When x > 1, f'(x) is positive, indicating that the function is increasing.
Therefore, the function is decreasing on the interval (-∞,1) and increasing on the interval (1,∞).
(c) all relative extrema, we examine the sign of the derivative in the neighborhood of the critical number x = 1. Since f'(x) changes sign at x = 1, this critical number corresponds to a relative minimum.

D: Negative 3.2 minus x + 19.1 greater-than-or-equal-to 14.2
Answers
Answer:
C
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The difference of –3.2 and the sum of a number and 19.1 is given as:
|-3.2 - (x + 19.1)| ≤ 14.2
Simplifying the left side of the inequality:
|-22.3 - x| ≤ 14.2
The absolute value of a number is always greater than or equal to 0, so we can split the inequality into two cases:
Case 1: -22.3 - x ≤ 14.2
-36.5 ≤ x
Case 2: -22.3 - x ≥ -14.2
-8.1 ≥ x
Combining the two cases, we get:
-36.5 ≤ x ≤ -8.1
Therefore, the correct option is:
A: Negative 3.2 minus (x + 19.1) less-than-or-equal-to 14.2.
Bailey works at an athletic store. He earns $90 per day plus an 11% commission on his sales. On Thursday, Bailey has $500 in sides. How much money does Bailey earn on Thursday, including his commission
Answers
Answer:
Bailey earned approximately $499.99 on Thursday, including his commission
Step-by-step explanation:
Bailey's earnings on Thursday consist of his base pay plus his commission. His base pay is $90, and his commission is 11% of his sales.
Let's call Bailey's sales on Thursday "S". Then his commission is 0.11S.
We know that Bailey's total earnings on Thursday were $500. So we can write an equation:
$90 + 0.11S = 500$
To solve for S, we can subtract $90$ from both sides of the equation:
$0.11S = 410$
Then we can divide both sides by $0.11$:
$S = 3,727.27$
So Bailey's sales on Thursday were $3,727.27.
To find Bailey's total earnings, we can add his base pay and commission:
$90 + 0.11(3,727.27) \approx 499.99$
So Bailey earned approximately $499.99 on Thursday, including his commission.

The edges of a triangle ABC are A, B, and C. Euclidean geometry yields a single plane and cube when the sides are not collinear. A polygon is formed when a triangle has three components and three angles. The corners of a triangle are the points at which the three edges meet. Triangle sides add up to 180 degrees.
To calculate x, we must use the fact that the sum of a triangle's interior angles is 180 degrees.
First, determine the size of angle B. Angle A is 60 degrees, and angle C is 75 degrees. So,
angle B = 180 minus angle A A - angle C angle B = 180 - 60 - 75 angle B = 45
D = 360 minus angle angle A angle B angle C angle D = 360° - 60° - 45° - 75° D is equal to 180 degrees.
angle E stands for angle. D\sangle E is equal to 180 degrees.
As a result, the value of x is:
x = the angle 180 degrees = E x
As a result, x equals 180 degrees.

Melody is planning a raised bed for her vegetable garden. How many square feet of wood does she need to create the bed? Hint: There is no bottom on the bed
Answers
Step-by-step explanation:
To calculate the amount of wood needed to create a raised bed, you will need to know the dimensions of the bed.
Assuming the raised bed is rectangular, you will need to know the length and width of the bed, as well as the height of the bed.
Once you have these dimensions, you can calculate the surface area of the raised bed by multiplying the length and width of the bed together. This will give you the area of the bottom of the bed.
To calculate the total surface area of the bed, including the sides, you will need to multiply this area by 2 (since there are two sides) and add this to the area of the bottom.
So the formula for calculating the total surface area of the raised bed is:
Total surface area = (2 x length x height) + (2 x width x height) + (length x width)
Once you have this total surface area, you can then calculate how much wood you need by multiplying it by the thickness of the wood.
For example, if the total surface area of the bed is 100 square feet and you plan to use 2-inch-thick boards, you would need 200 cubic feet of wood.
It's worth noting that this calculation assumes that the raised bed has straight sides and right angles. If the bed has a more complex shape, the calculation will be more difficult.
Complete the sentences about simplifying this expression once you given a value for b. 24 + b/b + 24 x 53.72
Answers
Answer:
Step-by-step explanation:
To simplify the expression 24 + b/b + 24 x 53.72,
we first need to substitute the given value of b into the expression.
For example, if b is equal to 5, we can replace all instances of b with 5 to get 24 + 5/5 + 24 x 53.72.
Next, we can simplify the division by evaluating 5/5, which equals 1.
Then, we can multiply 24 and 53.72 to get a product of 1288.28.
Finally, we can add the simplified terms to get a final result of 1312.28.
Therefore, the simplified expression, given that b is equal to 5, is 1312.28.

Answers
The simple rate of return for the investment (rounded to the nearest tenth of a percent) is: 0.1572 or 15.7%.
What is simple rate of return?Simple rate of return is a financial metric used to measure the profitability of an investment, calculated as the ratio of net income to the initial investment.
To calculate the simple rate of return for the investment, we need to first calculate the average annual net cash inflow.
Annual net cash inflow = Annual cash inflows - Annual depreciation expense
The annual depreciation expense can be calculated as:
Depreciation expense = (Initial cost - Salvage value) / Life of investment
Depreciation expense = ($34,000 - $0) / 15 years = $2,266.67 per year
Therefore, the average annual net cash inflow is:
Annual net cash inflow = $7,600 - $2,266.67 = $5,333.33
The simple rate of return can now be calculated as:
Simple rate of return = Average annual net cash inflow / Initial investment
Simple rate of return = $5,333.33 / $34,000 = 0.1572 or 15.7% (rounded to the nearest tenth of a percent)

What is number line?A number line is an image of numbers plotted on a straight line, either horizontally or vertically. We can compare numbers and execute simple arithmetic operations on them easily by writing the numbers down on a number line. The starting point of a number line is often regarded as zero (0). The numbers to the left of zero are all negative whereas the numbers on the right of zero are all positive. As a result, we may argue that on a number line, the value of numbers grows as we approach towards the right. The numbers on the right are thus greater than the ones on the left, according to this statement.

To find the area of the trapezoid triangle , we need to first find the length of the other diagonal
Since the center line is perpendicular to both diagonals, it divides the trapezoid triangle into two right triangles, ABC and ABD.
Using the Pythagorean theorem, we can find the length of BD:
BD = [tex]\sqrt{(AB^2 + AD^2)}[/tex]
BD = [tex]\sqrt{(10.2^2 + 7.5^2)}[/tex]
BD = 12.654
Now, we can use the formula for the area of a trapezoid:
A = (1/2) * (AB + CD) * h
where h is the height of the trapezoid, which is the distance between the parallel sides AB and CD.
To find h, we can use the formula for the area of a triangle:
A = (1/2) * b * h
where b is the base of the triangle and h is its height.
We can use triangle ABD, which is a right triangle, to find the height h:
h = AD = 7.5
Now we can substitute the values into the formula for the area of a trapezoid:
A = (1/2) * (AB + CD) * h
A = (1/2) * (10.2 + 15.3) * 7.5
A = 86.325
Therefore, the area of the trapezoid triangle ABC is approximately 86.325 square centimeters.
