All thre functions share the same y intercept

We can analyze the characteristics of the given functions based on the information provided in the table.

We cannot determine which function has the greatest maximum based on the table alone, as we do not have the complete graph of any of the functions.

We can see from the table that h(x) has an x-intercept of 0, which is the smallest among the three functions. Therefore, we can say that h(x) has the smallest x-intercept.

We can see from the table that g(x) has a minimum value of -204, which is the smallest among the three functions. Therefore, we can say that g(x) has the smallest minimum value.

We cannot determine if all three functions share the same domain based on the table alone. We can only see that all three functions have been evaluated at the same set of input values.

We can see from the table that the y-intercept of f(x) is 2, the y-intercept of g(x) is 3, and the y-intercept of h(x) is 4. Therefore, we can say that all three functions have different y-intercepts.

Therefore, the statements that can be used to compare the characteristics of the functions are:

h(x) has the smallest x-intercept.

g(x) has the smallest minimum value.

All three functions have different y-intercepts.

Answer:

Step-by-step explanation:

Answer:

B is greater than A by 1/4 of A

Step-by-step explanation:

Let's use the information given in the problem to write expressions for the values of a and b:

a = b - (1/5)b = (4/5)b

b is greater than a by the difference:

b - a = b - (4/5)b = (1/5)b

To express this difference as a fraction of a, we divide by a:

(b - a)/a = ((1/5)b)/((4/5)b) = 1/4

Therefore, b is greater than a by 1/4 of a.

At a significance threshold of 0.10, p-value(0.0005)< \(\alpha\) =0.10, therefore we reject \(H_{0}\).

Under the assumption of independence, the expected frequencies for contingency tables are

\(e_{ij} = \frac{(Row_{i}Total)(Column_{j} total)}{SampleSize}\)

Using the formula for the number of freshmen without body art: (247*168)/490=84.69.

State the null and alternative hypotheses:

\(\alpha = 0.10\)

\(H_{0}\): There is a connection between body art and class standing 

Ha: There is no connection between class standing  and rejection from body art. \(H_{0}\) if the probability is less than 0.10.

the test statistic for independence is

\(X^2= \sum\limits_i \sum\limits_j\frac{(f_{ij}-e_{ij} )^2 }{e_{ij} }\)

where fij = observed frequency for the contingency table category in rows i and j

eij = expected frequency for the contingency table category in rows i and j based on the assumption of independence

We only need to add up the values as they have already been obtained and are listed in the table to obtain the chi-square value.

Therefore,

\(X^2= 2.56+ 4.33+1.1+0.02+0.69+0.02+1.2+0+0.49+0.51+0.33+0.25+4.99+4.31+8.41+0.27\)

\(X^{2} = 29.48\)

Consequently, the probability of p-value=0.0005

Yes, the answer is B. Boots

Edgenuit.y 2021

On boots Sasha applied the coupon of 25%, option B is correct.

percentage, a relative value indicating hundredth parts of any quantity.

If Sasha paid a total of $208.94 and applied the 25% coupon to one of the items, then we can set up the following equation:

$85.75 + $71.99 + $24.25 + $44.95 - 0.25x = $208.94

where x is the original price of the item to which Sasha applied the coupon.

Simplifying the equation, we get:

$226.94 - 0.25x = $208.94

0.25x = $18.00

x = $72.00

This means that the original price of the boots was $71.99, and Sasha applied the 25% coupon to the boots, getting a discounted price of:

$71.99 - 0.25($71.99) = $53.99

The parent function that has a domain of all real values of x and a range of y ≥ 0 is :  Absolute value

What is Function ?

A function is a mathematical relationship between two sets of values, typically represented by variables, where each input (or domain value) maps to a unique output (or range value). In other words, a function assigns exactly one output value to each input value.

The absolute value function, denoted as |x|, has a domain of all real values of x, meaning it can accept any real number as input. The range of the absolute value function is y ≥ 0, which means that the output (or the absolute value of x) will always be greater than or equal to 0.

Reciprocal, cubic, and linear functions do not satisfy the criteria of having a range of y ≥ 0 for all real values of x. The reciprocal function, for example, has a domain that excludes 0, as division by zero is undefined, and its range does not include negative values. The cubic and linear functions, in general, can have a range that includes negative values depending on their coefficients and shifts.

Therefore, The parent function that has a domain of all real values of x and a range of y ≥ 0 is :  Absolute value

If rectangle has an area of 114cm squared and a perimeter of 50 cm, the dimensions of the rectangle are approximately 5 cm by 22.8 cm.

Let's assume the length of the rectangle is "l" and the width is "w". We can start by using the formula for the area of a rectangle, which is A = lw. From the given information, we know that the area is 114cm².

So, we have:

lw = 114

Next, we can use the formula for the perimeter of a rectangle, which is P = 2l + 2w. From the given information, we know that the perimeter is 50cm.

So, we have:

2l + 2w = 50

We now have two equations with two variables, which we can solve using substitution or elimination. Let's use substitution by solving the first equation for l:

l = 114/w

We can then substitute this expression for l in the second equation:

2(114/w) + 2w = 50

Multiplying both sides by w to eliminate the fraction, we get:

228 + 2w² = 50w

Rearranging and simplifying, we get a quadratic equation:

2w² - 50w + 228 = 0

We can solve for w using the quadratic formula:

w = [50 ± √(50² - 4(2)(228))]/(2(2)) ≈ 11.4 or 5

Since the length and width must be positive, we can discard the solution w = 11.4. Therefore, the width of the rectangle is approximately 5 cm. We can then use the equation lw = 114 to solve for the length:

l(5) = 114

l ≈ 22.8

The lengths of the right-angled triangle are 6 and 8.

A right-angled triangled is a triangle that has one of its angles equal to 90°. The sum of the other two interior angles is also equal to 90°.

The Pythagoras theorem relates the three sides of a right-angled triangle through a simple equation. According to the Pythagoras theorem,

hypotenuse^2 = base^2 + opposite^2

Let base = b, so opposite = b + 2

So,

10^2 = b^2 + (b+2)^2

100 = b^2 + b^2 + 4b + 4

100 = 2b^2 + 4b + 4

50 = b^2 + 2b + 2

b^2 + 2b - 48 = 0

solving this quadratic equation gives, b = 6 and b = -8. Since length cannot be negative, the base is 6 feet and the opposite is 8 feet.

The line parallel to the x-axis passing through the points (5,5) and (-5,5) has a slope of 0, indicating a horizontal line with a constant y-coordinate value of 5.

To determine the slope of the line that represents this relationship, we can use the formula for slope, which is given by:

slope = (change in y-coordinates) / (change in x-coordinates)

In this case, we are given two points on the line: (5,5) and (-5,5).

The change in y-coordinates is 5 - 5 = 0, as the y-coordinate remains constant.

The change in x-coordinates is -5 - 5 = -10.

Substituting these values into the slope formula, we get:

slope = 0 / -10 = 0

Therefore, the slope of the line that represents this relationship is 0.

A slope of 0 indicates that the line is parallel to the x-axis. This means that the line has a constant y-coordinate value for all x-coordinate values. In this case, the line passes through the point (5,5) and (-5,5), and it remains at y = 5 for all x-values.

Visually, a line with a slope of 0 would be a horizontal line on the coordinate plane. It does not have an upward or downward slope but remains parallel to the x-axis.

It's important to note that the slope of 0 indicates a relationship where the dependent variable (y) does not change with respect to the independent variable (x). In this case, no matter the value of x, the corresponding y-value remains constant at 5.

Answer:

The minimum sample size should be of 381.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \(\pi\), and a confidence level of \(1-\alpha\), we have the following confidence interval of proportions.

\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)

In which

z is the zscore that has a pvalue of \(1 - \frac{\alpha}{2}\).

The margin of error is given by:

\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)

95% confidence level

So \(\alpha = 0.05\), z is the value of Z that has a pvalue of \(1 - \frac{0.05}{2} = 0.975\), so \(Z = 1.96\).

Without any prior knowledge of the proportion, what should be our minimum sample size

We dont know the population proportion, so we use \(\pi = 0.5\), which is when the largest sample size is needed. We have to find n for which \(M = 0.05\). So

\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)

\(0.05 = 1.95\sqrt{\frac{0.5*0.5}{n}}\)

\(0.05\sqrt{n} = 1.95*0.5\)

\(\sqrt{n} = \frac{1.95*0.5}{0.05}\)

\((\sqrt{n})^2 = (\frac{1.95*0.5}{0.05})^2\)

\(n = 380.25\)

Rounding up

The minimum sample size should be of 381.

By subtracting the taxes from the gross pay we can see that Carlos' net pay is $1,500.30

We know that the gross pay is $1,800, now we need to subtract the social security and taxes.

First, there is a 6.2% and 19% in taxes, adding that we get:

6.2% + 9% = 15.2%

Then we need to subtract a 15.2% of the gross pay, this will give:

P = $1,800*(1 - 15.2%/100%) =  $1,800*(0.848) = $1,526.40

And now we also need to subtract the Medicare, which is $26.10, it gives:

$1,526.40 - $26.10 = $1,500.30

Answer:

C. y = 2x - 4

Step-by-step explanation:

the correct answer is: C y = 2x - 4. The value of y for given expression is y = 2x - 4

To solve the equation 8x - 4y = 16 for y, we need to isolate y on one side of the equation. Let's proceed with the steps:

1. Move the term containing y to the other side of the equation:

8x - 4y = 16

Subtract 8x from both sides:

-4y = 16 - 8x

2. Divide both sides by -4 to solve for y:

y = (16 - 8x) / -4

Now, let's simplify the expression for y:

y = -16/4 + (8x)/4

y = -4 + 2x

in a basic right triangle the small side is always one shorter than the big side which is always one smaller than the hypotenuse.

The sample should be taken to provide a 95% confidence interval is 200.

A confidence interval is made up of the mean of your estimate plus and minus the estimate's range. This is the range of values you expect your estimate to fall within if you repeat the test, within a given level of confidence.

Confidence is another name for probability in statistics.

Given the planning value for the population proportion,

probability, p = 0.25

q  = 1 - p = 1 - 0.25

q = 0.75

margin of error = E = 0.06

value of z at 95% confidence interval is 1.96,

the formula for a sample is,

n = (z/E)²pq
