Step-by-step explanation:
The symbol ≤ means less than or equal to. The symbol ≥ means greater than or equal to.The notation a ≤ b or a ⩽ b means that a is less than or equal to b (or, equivalently, at most b, or not greater than b). The notation a ≥ b or a ⩾ b means that a is greater than or equal to b (or, equivalently, at least b, or not less than b).The five inequality symbols in Maths are greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤), and not equal to symbol (≠).

Given:
The given triangle is a right triangle.
The length of the hypotenuse is 31 units.
The length of the leg is 23 units.
One of the angle is x.
We need to determine the value of x.
Value of x:
The value of x can be determined using the trigonometric ratio.
Thus, we have;
[tex]sin \ \theta=\frac{opp}{hyp}[/tex]
Substituting [tex]\theta=x[/tex], the side opposite to the angle x measures 23 units and the hypotenuse is 31.
Thus, we have;
[tex]sin \ x=\frac{23}{31}[/tex]
Dividing, we get;
[tex]sin \ x=0.74[/tex]
Taking [tex]sin ^{-1}[/tex] on both sides of the equation, we get;
[tex]x=sin^{-1}(0.74)[/tex]
[tex]x=47.7[/tex]
Rounding off to the nearest whole integer, we get;
[tex]x=48[/tex]
Thus, the value of x is 48°

Seven candidates are running for three different class offices: president, vice president,
and secretary. In how many ways can the offices be filled with these candidates?
Work Shown:
7 ways to pick the president.
6 ways to pick the VP
5 ways to pick the secretary
7*6*5 = 210 ways to pick the three people from a pool of seven. Order matters because the positions are different. Note the count down from 7 to 6 to 5 which indicates that any given person cannot run for more than one office.
You can use the permutation formula with n = 7 and r = 3
The permutation formula is [tex]_n P_r = \frac{n!}{(n-r)!}[/tex] where the exclamation marks represent factorials.
There are 210 distinct ways to assign seven candidates to three different class offices (president, vice president, and secretary), based on permutation principles.
The question involves finding out in how many ways three different class offices (president, vice president, and secretary) can be filled from a pool of seven candidates. This is a permutations problem because the order in which the candidates are chosen matters (as the offices are distinct). To solve this, we use the permutation formula. For the first office, you have 7 choices (any of the 7 candidates can fill it). Once the first position is filled, you are left with 6 candidates for the second office. Similarly, after filling the second office, there are 5 candidates left for the third office.
Therefore, the total number of ways to fill these positions is the product of these choices, which is calculated as:
7 × 6 × 5 = 210 ways.
This means there are 210 distinct ways to assign these seven candidates to the three available class offices, assuming no candidate can hold more than one office simultaneously.

What is scaling ?
It is the method to resize drawing with comparing to true size of object which uses proportion or ratio. For example, Mapping of earth, drawing prototype of automobiles.
It is given that :
A small rectangle has a length of 8 and width of 4 and a large rectangle has a length of 25.6 and width of a, then
The area of the small rectangle is :
area = length · width
area = (8)(4) = 32 units²
The scale factor is ...
scale factor = greater length / smaller length
= 25.6/8
= 3.2

Answer:
19. 1400 ft^2
20. 1680 + 112pi m^3
For 20, a decimal answer would be 2031.86
Step-by-step explanation:
19. Lateral surface area refers to the area without including any horizontal planes(the tops and the bottoms - hence the name lateral). The lateral surface area of this prism is simply 5 equivalent rectangles. Each rectangle has an area of 280(14*20). Thus, the answer is 280*5 = 1400 [tex]ft^{2}[/tex]
20. The volume of a shape such as this(where the horizontal planes are always the same shape) can be calculated by the area of the base times the height. In this case, the area of the base is the semi circle (area of [tex]\frac{4*4*\pi}{2}[/tex]). The area of the rectangle is 15 * 8 = 120. Adding these together gets you 120 + 8pi. Multiplying this by the height of 14 gets you 1680 + 112[tex]\pi[/tex] [tex]m^3[/tex]

We have,
Here are the steps to find whether each cube root or square root lies between 2 and 3, 4 and 5, or 9 and 10:
Start with the first cube root or square root, ∛800.
Estimate the value of the root.
For ∛800, we can estimate that it's between 8 and 9, since 8 cubed is 512 and 9 cubed is 729.
So, ∛800 must be somewhere in between.
Determine which range the estimated value falls into.
Since 8 is between 2 and 3, ∛800 must also be between 2 and 3.
Repeat the process for the remaining cube roots and square roots, using the same ranges.
Here are the results:
∛800: Between 2 and 3
∛101: Between 4 and 5
∛90: Between 4 and 5
∛20: Between 2 and 3
√7: Between 2 and 3
√20: Between 4 and 5

What is a fraction?Fractions represent the parts of a whole or collection of objects. A fraction has two parts. The number on the top of the line is called the numerator.The number on the bottom of the line is called the denominator.
Now it is given that,
Amount of fuel in the car = 16 3/4 gallons = 67/4 gallons
Amount of fuel used = 2/5 gallons
Therefore,
Amount of fuel left in the car = Amount of fuel in the car - Amount of fuel used
⇒ Amount of fuel left in the car = 67/4 - 2/5
⇒ Amount of fuel left in the car = 327/20 gallons

Bottles of mango juice are assumed to contain 275 milliliters of juice. There is some variation from bottle to bottle because the filling machine is not perfectly precise. Usually, the distribution of the contents is approximately Normal. An inspector measures the contents of seven randomly selected bottles from one day of production. The results are 275.4, 276.8, 273.9, 275.0, 275.8, 275.9, and 276.1 milliliters. Do these data provide convincing evidence at α = 0.05 that the mean amount of juice in all the bottles filled that day differs from the target value of 275 milliliters? (4 points)
Group of answer choices
Because the p-value of 0.0804 is greater than the significance level of 0.05, we fail to reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day does not differ from the target value of 275 milliliters.
Because the p-value of 0.0804 is greater than the significance level of 0.05, we reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day differs from the target value of 275 milliliters.
Because the p-value of 0.1609 is greater than the significance level of 0.05, we fail to reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day does not differ from the target value of 275 milliliters.
Because the p-value of 0.1609 is greater than the significance level of 0.05, we reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day differs from the target value of 275 milliliters.
Because the p-value of 1.5988 is greater than the significance level of 0.05, we fail to reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day does not differ from the target value of 275 milliliters.
Answer:
The correct option is;
c. Because the p-value of 0.1609 is greater than the significance level of 0.05, we fail to reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day does not differ from the target value of 275 milliliters.
Step-by-step explanation:
Here we have the values
μ = 275 mL
275.4
276.8
273.9
275
275.8
275.9
276.1
Sum = 1928.9
Mean (Average), = 275.5571429
Standard deviation, s = 0.921696159
We put the null hypothesis as H₀: μ₁ = μ₂
Therefore, the alternative becomes Hₐ: μ₁ ≠ μ₂
The t-test formula is as follows;
[tex]t=\frac{\bar{x}-\mu }{\frac{s}{\sqrt{n}}}[/tex]
Plugging in the values, we have,
Test statistic = 1.599292
[tex]t_{\alpha /2}[/tex] at 7 - 1 degrees of freedom and α = 0.05 = ±2.446912
Our p-value from the the test statistic = 0.1608723≈ 0.1609
Therefore since the p-value = 0.1609 > α = 0.05, we fail to reject our null hypothesis, hence the evidence suggests that the mean does not differ from 275 mL.
Answer:
Because the p-value of 0.1609 is greater than the significance level of 0.05, we fail to reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day does not differ from the target value of 275 milliliters.

a. No, the domain values are at regular intervals.
b. No; a different value is added to each range value.
C. No; there is no relationship between the x value and its corresponding y value.
d. Yes; the domain values are at regular intervals and the range values have a common factor 2
Please select the best answer from the choices provided
Final answer:
The data provided do not represent an exponential function, as there is no constant ratio between y-values for evenly spaced x-values. The correct answer among the given options is 'c' suggesting there is no clear relationship between the x and y values.
Explanation:
From the provided data, it is not clear whether there is an exponential relationship between the x and y values. To determine whether a set of data represents an exponential function, we typically look for a constant ratio between successive y-values when the x-values are evenly spaced. In other words, as x increases by regular intervals, the y values should be multiplied by a constant factor if the relationship is exponential. However, the y-values listed (1, 1, 1, 2, 4, 1, 8) do not show a common factor between each term. Therefore, the data do not represent an exponential relationship, making option 'd' incorrect.
Let's evaluate the other options:
a. No, the domain values are at regular intervals: This is a characteristic of an exponential function, but the range values must also have a common factor, which they do not in this case.
b. No; a different value is added to each range value: This could suggest a linear or polynomial relationship rather than an exponential one. However, without additional context or a pattern in the additions, we cannot be certain of this either.
c. No; there is no relationship between the x value and its corresponding y value: Based on the erratic pattern of y-values, this option seems the most accurate as it suggests that the data does not correspond to any clear mathematical relationship.
The best choice given the options is likely 'c' as it accurately describes the lack of consistent relationship between x and y values necessary for a function to be exponential.

Joanna has been saving for retirement for 40 years. She made monthly deposits of $275 and earned 5.6% annual interest, compounded monthly. According to her account documents, after these 40 years, she has a balance of $491,730.35 in her account. How much of this did Joanna contribute and how much of this is interest?
Joanna deposited $132000 and her interest amount is $359730.35
Step-by-step explanation:
Monthly deposit = $275
Interest = 5.6%
Time = 40 years
After 40 years her account balance = $491730.35
If she deposit $275 monthly then after 40 years she will have deposited ,
= 275 x 12 x 40
= $132000
The remaining is her interest amount.
Interest amount = 491730.35 - 132000
= $359730.35
Joanna deposited $132000 and her interest amount is $359730.35
