What is the slope of a line that is parallel to the line y = x 2?

Answer:

well non of the answer choices are exact but i would say a/the first one. im not sure but they should add up to about 7.65%.

Step-by-step explanation:

Answer:

So each party – employee and employer – pays 7.65% of their income, for a total FICA contribution of 15.3%. To calculate your FICA tax burden, you can multiply your gross pay by 7.65%:

BUT EACH FICA TAX IS 6.2% Social security and 1.45% respectively

The reason it says 7.65 because it also depends on where you live, but it should be around the 7.65 to 7.9 mark

The statement which is true is D. 65% of the seventh-grade students prefer the water park.

Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

A : Total number of students = 120

Number of students who prefer amusement park = 14 + 16 = 30

Percentage of students who prefer amusement park = 30 / 120 = 0.25 = 25%

B : Total number of eighth grade students = 80

Number of eighth grade students who prefer amusement park = 16

Percentage = 16 / 80 = 0.2 = 20%

C : Total number of students = 120

Number of students who prefer water park = 26 + 64 = 90

Percentage = 90 / 120 = 0.75 = 75%

D : Total number of seventh grade students = 40

Number of seventh grade students who prefer water park = 26

Percentage = 26 / 40 = 0.65 = 65%

Hence the option D is the correct percentage.

To Find :-

Answer :-

We have ,

Add and subtract 8² .

Hence the required answer is (x+8)² -77.

The correct statement is "Stores A and B have an equal spread." (option b).

To determine the spread of the data, we first need to find the range. The range is calculated by subtracting the smallest number from the largest number in a dataset.

For Store A:

The smallest number recorded is 2, and the largest number is 4. Therefore, the range of Store A is 4 - 2 = 2.

For Store B:

The smallest number recorded is 3, and the largest number is 5. Thus, the range of Store B is 5 - 3 = 2.

Comparing the ranges of both stores, we see that both Store A and Store B have the same range, which means the spread of the data is equal for both stores.

Therefore, the correct statement is:

b) Stores A and B have an equal spread.

0.14 mg of a certain drug will be present after 9 hours.

To determine the milligrams of the drug present after 9 hours, we can substitute h = 9 into the function D(h) = \(5e^{(-0.4h)\) and calculate the result.

D(h) = \(5e^{(-0.4h)\)

D(9) = \(5e^{(-0.4 * 9)\)

Now, let's calculate the value:

D(9) ≈ \(5e^{(-0.4 * 9)\) ≈ \(5e^{(-3.6)\) ≈ 5 * 0.02447 ≈ 0.12235

Current standards indicate that a single subject research design should demonstrate a functional relation between independent and dependent variables with a minimum of three effects.

Single subject research designs, also known as single case experimental designs, are experimental designs commonly used in behavioral sciences to study the effects of interventions or treatments on individuals. These designs involve repeated measurement of the dependent variable under different conditions or phases.

To establish a functional relation between the independent and dependent variables, current standards suggest that a minimum of three effects should be demonstrated. These effects typically consist of a baseline phase, an intervention phase, and a return-to-baseline phase. The baseline phase serves as a control condition where the independent variable is absent or has no effect on the dependent variable. The intervention phase introduces the independent variable, and its effects on the dependent variable are observed.

Answer:

Step-by-step explanation:

For the equation where you have to find x :

First create equivalent expressions within the equation that all have equivalent bases.

5^4z-14 = 5^z+4

Because the bases are the same this means the expressions can only be equal if the exponents are equal as well.

4x-14= z+4

Now we will start to solve for x.

We move all terms without an x to the right side of the equation.

4x -14 = z +4         * Add 14 to both sides of the equation.

    +14      +14  

____________

4x = z +4 + 14        * Add 4 and 14

_____________

4x = z+18

Now divide each term in 4x = z +18 by 4.

4x/4 = z/4 + 18/4

Simplify the left side of the equation.

Cancel out the common factor of 4.

x = z/4 + 18/4

Simplify the right side.

Cancel the common factor of 18 and 4

Factor 2 from 18

x= z/4+ 2(9)/4

Then we cancel out the common factors.

The answer you would get in the end is:

x= z/4 + 9/2

The value of x in the equation is 3 3/5

The graph is translated down by nine units

If the exponential equation has the same base on both sides, then you can simply equate the exponents and solve for the variable.

If the exponential equation has different bases on both sides, then you can use logarithms to convert the equation into a form that can be solved algebraically.

We know that;

5^4x - 14 = 5^x + 4

4x - 14 = x + 4

Collect like terms

4x - x = 4 + 14

Answer:   C

Step-by-step explanation: We see that e is 6 for $2.70 and d is 12 for $6.00.  Half of 6 is 3 and 2.70 is less than 3 so the cheapest price can't be d. Then, we have 9 for 3.60. 3.60 divided by 9 is 0.40 per which is cheaper than a (0.42 per) so a and d can't be the cheapest. 3 for 1.38 means 0.46 per which is more expensive than a so it also cannot be b. Now we only have c and e left. We divide 2.70 by 6 and find out that the answer is 0.45 which is also more expensive than a. So, the answer is c.

The proof of trigonometric identity (sin(x) + tan(x))/sin(x) = 1 +secx is given below.

The given trigonometric identity is,

(sin(x) + tan(x))/sin(x).

We know that tan(x) = sin(x)/cos(x), so we can substitute that in:

sin(x)/ sin(x) + sin(x)/cos(x) / sin(x)

We can simplify the fraction in the numerator:

sin(x)/ sin(x) + sin(x)/sin(x)cos(x)

We know that sin(x)/sin(x) = 1, so we can simplify further:

1+ 1/cos(x)

We know that 1/cos(x) = sec(x), so we can substitute that in:

1 + sec(x).

Now we have the same expression as the right-hand side of the identity, so we have proven that:

sin(x) + tan(x)/sin(x) = 1 + sec(x)

Therefore, (sin(x) + tan(x))/sin(x) = 1 +secx.

The dimensions of the field should be 125m by 100m to enclose the maximum area.

To solve this problem, we can use the fact that the area of a rectangle is given by A = lw, where l and w are the length and width of the rectangle, respectively. Since the field is to be subdivided into four congruent plots, we can express the width in terms of the length as w = (1/4)(l).

We can then use the fact that the total length of fencing available is 6000m to set up an equation for the perimeter of the rectangle, which is given by P = 2l + 5w. Substituting w with (1/4)(l), we get P = 2l + 5((1/4)(l)) = (9/2)l.

Solving for l in terms of P, we get l = (2/9)P. Substituting this expression for l into the equation for the area, we get A = (1/4)(l)(w) = (1/4)(l)((1/4)(l)) = (1/16)l^2.

We can now express the area in terms of P as A = (1/16)((2/9)P)^2 = (4/81)(P^2). To find the maximum area, we can take the derivative of A with respect to P and set it equal to zero, which gives dA/dP = (8/81)P = 0. This implies that P = 0 or P = 81/8. Since P cannot be zero, we have P = 81/8.

Substituting this value of P back into the equation for l, we get l = (2/9)(81/8) = 18.75. Finally, substituting l and w = (1/4)(l) into the equation for A, we get A = (1/16)(18.75)(4.6875) = 117.1875. Therefore, the dimensions of the field should be 125m by 100m to enclose the maximum area.

The standard deviation of a larger sample will be closer to the standard deviation of the population than the standard deviation of a smaller sample, making it a better estimate of the population standard deviation.

In order to measure the variability or spread of a population, a population standard deviation is utilized. This is frequently unknown and estimated using the standard deviation of a random sample taken from the population. The sample standard deviation is the measure of variability for a set of data values obtained from a sample.The sample standard deviation is preferable to the population standard deviation for samples, particularly large samples. The sample standard deviation, abbreviated as "s", is used to estimate the population standard deviation, represented by the Greek letter sigma, which is unknown in this situation. The sample standard deviation is more likely to accurately reflect the true population standard deviation when it is calculated from a large sample size.Samples from populations that have a normal distribution provide the most precise estimate of the population standard deviation. If the population distribution is not normal, the sample size should be at least 30. However, for smaller samples, it is impossible to estimate the population standard deviation using the sample standard deviation. This is particularly true when the population has an atypical or unusual distribution.

In conclusion, the sample standard deviation (s) is a better estimate of the population standard deviation for large samples.
