Answers
The expression that represents the phrase 'one third the sum of 12 and a number' is B.) 1/3(12+x).
To represent the phrase "one third the sum of 12 and a number", we can break it down into two parts:
1. The sum of 12 and a number
2. One third of that sum
The expression for the sum of 12 and a number is (12 + x). Then, one third of that sum is [tex]\(\frac{1}{3}(12 + x)\).[/tex]

The _______ represents the expected proportion of intervals that will contain the parameter if a large number of different samples of size n is obtained. it is denoted _______.
Answers
The concept referred to in the question is the 'confidence interval', which represents the estimated range that will contain the parameter in the event of obtaining a large quantity of different samples of size n. The denoted term '____' is the standard error (SE), which describes the standard deviation of these sample means distribution. As the number of samples increases, according to the central limit theorem, these sample sums or means tend towards a normal distribution.
Explanation:The portion of the question, 'The _______ represents the expected proportion of intervals that will contain the parameter if a large number of different samples of size n is obtained...' refers to the confidence interval. The confidence interval is a range of values, derived from statistical analysis, that is likely to contain the parameter of interest. For instance, a 0.95 confidence interval stands for a 95% probability that the population parameter will fall within this range.
The second fill-in-the-blank part of the question, 'it is denoted _______.' refers to the standard error. The standard error denoted as SE or rarely s.e., represents the standard deviation of the sampling distribution of the mean or in simpler words, it highlights how much our sample mean might differ from the actual population mean.
As the number of different samples (n) gets larger, the sampling distribution of the sum, ΣX, or the mean, X, tends towards the normal distribution, according to the central limit theorem. This feature is harnessed in diverse areas such as probability theory and statistics.

What is the inverse of the function f(x) = 2x - 10?
Answers
Answer:
[tex]f^{-1}(x)=\frac{x+10}{2}[/tex]
Step-by-step explanation:
We ate asked to find the inverse of the given function [tex]f(x)=2x-10[/tex].
To find the inverse of function, first of all we will replace [tex]f(x)=y[/tex] and then interchange x and y values as shown below:
[tex]y=2x-10[/tex]
Inter-change x and y variables:
[tex]x=2y-10[/tex]
Solve for y using opposite operations:
[tex]x+10=2y-10+10[/tex]
[tex]x+10=2y[/tex]
Switch sides:
[tex]2y=x+10[/tex]
Divide both sides by 2:
[tex]\frac{2y}{2}=\frac{x+10}{2}[/tex]
[tex]y=\frac{x+10}{2}[/tex]
We will inverse function notation [tex]f^{-1}(x)[/tex] to write the inverse function as:
[tex]f^{-1}(x)=\frac{x+10}{2}[/tex]
Therefore, our required inverse function would be [tex]f^{-1}(x)=\frac{x+10}{2}[/tex].

In isosceles ∆DEK with base DK, EF is the angle bisector of ∠E, m∠DEF = 43°, and DK = 16cm. Find: KF, m∠DEK, m∠EFD.
Answers
EF is the angle bisector of ∠E,
m∠DEF = 43°= m∠FEK ( the bisector divide the angle in two equal angles)
so m∠DEK = m∠DEF + m∠FEK = 43 + 43 = 86
∆DEK is isoceles triangle (given)
the two base angles are equal m∠EDK = m∠DKE
and the sum of angles in a triangle = 180
so m∠DEK + m∠EDK+ m∠DKE = 180
86 + m∠EDK+ m∠DKE = 180
2 x m∠EDK = 94
m∠EDK = 94 / 2 = 47
in triangle DEF
m∠EDF + m∠E FD+m∠FED= 180
47 +m∠E FD + 4 3 = 180
m∠E FD = 180-43-47 = 90
Find: KF?
in an isoseles triangle the bisector is in the same time median so
KF= DK / 2 = 16/ 2 = 8 cm

What's the relationship between compound interest and exponential growth?
Answers
the exponential functions are the family of functions that have the form a^x, where a > 1.
Compound interest is modeled as an exponentila growth problem. Another phenomenon that can be modeled as exponential growth is population growth.
In other words, compound interest is an application of exponential growth.
Final answer:
Compound interest and exponential growth both involve the concept of compounding, where growth is based on previous amounts. Compound interest refers to interest earned on past interest, causing savings to grow over time. Similarly, compound growth rates result in exponential growth.
Explanation:
The relationship between compound interest and exponential growth is that they both involve the concept of compounding, where the growth or increase is based on previous amounts. Compound interest refers to the interest earned on past interest, causing the total amount of financial savings to grow over time. Similarly, compound growth rates mean that the rate of growth is multiplied by a base that includes past growth, resulting in an exponential growth curve.
For example, if you have $1,000 in a bank account with a compound interest rate of 5% per year, the interest earned each year is added to the principal amount and becomes part of the new base for calculating future interest. As a result, the amount of money in the account grows exponentially over time. This relationship can also be seen in other areas, such as population growth or economic growth rates.

To graph the inequality y ≤ 1 - 3x, we can start by graphing the equation y = 1 - 3x. The graph should be a solid line passing through the y-axis at 1 and the x-axis at 1/3. The shaded region below the line represents the solution set.
Explanation:The given inequality is y ≤ 1 - 3x. To graph this inequality, we can start by graphing the equation y = 1 - 3x. This equation represents a line with a y-intercept of 1 and a slope of -3. We can plot the y-intercept at (0, 1) and use the slope to find additional points on the line.
For example, if we increase x by 1, y will decrease by 3. So, when x = 1, y = -2. By connecting these points and extending the line, we can have a line passing through the y-axis at 1 and the x-axis at 1/3.
To graph the inequality y ≤ 1 - 3x, we shade the region below the line because any point in this region will satisfy the inequality.
Therefore, the graph should be a solid line with arrows at both ends, passing through the y-axis at 1 and the x-axis at 1/3, and the region below the line shaded.

Answers
Final answer:
Mt. McKinley is 20,318 feet tall. This is found by adding Mt. Whitney's height of 14,492 feet to the additional 5,826 feet that Mt. McKinley is taller by.
Explanation:
The question asks how tall Mt. McKinley is. First, we know Mt. Whitney has a height of 14,492 feet. According to the question, Mt. McKinley is 5,826 feet taller than Mt. Whitney. To find the height of Mt. McKinley, we need to add these two measurements together.
Step 1: Write down the height of Mt. Whitney: 14,492 feet.
Step 2: Add the additional height of Mt. McKinley to Mt. Whitney's height: 14,492 feet + 5,826 feet.
Step 3: Perform the addition: 14,492 + 5,826 = 20,318 feet.
Therefore, Mt. McKinley is 20,318 feet tall.

The acceleration of an object varies directly with the force acting on it. If a force of 70 newtons causes an acceleration of 6.5 m/s2, what force will cause ann acceleration of 8m/s2? round your answer the hundredths place
Answers
Using Newton's Second Law of Motion, and the principle that acceleration is directly proportional to the applied force, a force of approximately 86.15 newtons will cause an acceleration of 8 m/s².
Explanation:The question relates to the principle stated in Newton's Second Law of Motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In this case, we can assume the mass of the object remains unchanged.
To find the force that will cause an acceleration of 8 m/s², we can set up a direct proportion based on the given data (70 N correlates with 6.5 m/s²):
70 N / 6.5 m/s² = X N / 8 m/s²
Solving this for X gives X = (70 N * 8 m/s²) / 6.5 m/s². Round your answer to the nearest hundredth, you get approximately 86.15 N.

Help me please i have a test coming up
Answers
Answer:
Step-by-step explanation:
2400 × 0.15 = 360
2400 - 360 = 2040
2040 × 1/8 = 255 kg of Cement
2040 × 2/8 = 510 kg of Sand
2040 × 5/8 = 1275 kg of Stone
To check if it is right
255 + 510 + 1275 = 2040 kg
1 cubic meter of concrete the weight of water is 360 Kg, the weight of cement is 255 Kg, the weight of sand is 510 Kg and the weight of stone is 1275 Kg and this can be determine by forming the linear equation in one variable.
Given :
1 cubic meter of concrete has a wight of 2400 kg.15% of the concrete is water.The rest of the ingredients are cement, sand and stone. The weights are in a ratio of 1:2:5.The weight of the water in the concrete will be:
