It makes sense

Total fee = $75

Number of months = 3

Divide the total fee by the number of months

75/3 = $25 per month

Step-by-step explanation:

The total price of sneakers including tax will be equal to $20.75.

The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.

As per the given information in the question,

Price of sneakers = $20

Tax on sneakers = 3.75%

Then, the amount of tax will be,

(20 × 3.75)/100

= 75/100

= $0.75

Then, the total price of the sneakers will be,

$20 + $0.75

= $20.75

Domain of the function represented by the graph of a quadratic function y = \(x^2\) – 4 with a minimum value at the point (0,-4) is all real numbers.

The correct answer is option D.

To determine the domain of the quadratic function y = \(x^2\) - 4, we need to consider the x-values for which the function is defined. Since a quadratic function is defined for all real numbers, the domain of this function is "all real numbers."

Let's analyze the given function and its graph to understand why the domain is "all real numbers."

The function y =  \(x^2\) - 4 represents a parabola that opens upward, which means it extends infinitely in both positive and negative x-directions. The vertex of the parabola is at the point (0, -4), indicating that the minimum value of the function occurs at x = 0.

Since there are no restrictions or limitations on the x-values for which the function is defined, the domain is unrestricted and encompasses all real numbers. In other words, the function can be evaluated and calculated for any real value of x, whether it is a negative number, zero, or a positive number.

  area = 5 1/3 square units

Step-by-step explanation:

You want the area under the square root curve, above y=0, from x=0 to x=4.

The area is found by integrating a differential of area over appropriate limits. A vertical slice will have hight √x and width dx, so we have ...

  dA = (√x)dx

  A = ∫(√x)dx

The power rule can be used for the integration:

  \(\displaystyle A=\int_0^4{x^{\frac{1}{2}}}\,dx=\left[\dfrac{x^{\frac{3}{2}}}{\frac{3}{2}}\right]^4_0=\dfrac{2}{3}(4^\frac{3}{2})=\dfrac{16}{3}=\boxed{5\dfrac{1}{3}}\)

The area of the region is 5 1/3 square units.

__

Additional comment

You will notice that the area is bounded by a rectangle 4 units wide and 2 units high, for an area of 4·2 = 8. The area under the parabolic curve is 2/3 of that: 2/3·8 = 16/3 = 5 1/3 square units.

This fraction will be true for any area bounded by a parabola where the vertex is one of the corners of the rectangle.

Answer:

A.) Even.

Step-by-step explanation:

If a function is an even function, then

F(-x) = f(x)

Also, if a function is an odd function, then, f(-x) = -f(x)

You are given the below function

f(x) = 1 + 3x^2 − x^4

Let x = 2

Substitute 2 for x in the function

F(x) = 1 + 3(2)^2 - (2)^4

F(x) = 1 + 3(4) - 16

F(x) = 1 + 12 - 16

F(x) = -3

Also, Substitute -2 for x in the function

F(x) = 1 + 3(-2)^2 - (-2)^4

F(x) = 1 + 3(4) - 16

F(x) = 1 + 12 - 16

F(x) = -3

Since f(-x) = f(x), we can conclude that

F(x) = 1 + 3x^2 - x^4 is even

Answer:

A. Inscribed Angle

Step-by-step explanation:

Because the angles are inscribed in the circle, the angle lie on arcs which mean that the angles have to add up to 360 degrees just like a circle is 360 degrees, making it a quadrilateral that is inscribed!

The missing information in the paragraph proof should be considered as the Inscribed Angle.

In terms of geometry, an inscribed angle should be the angle that should be created in the interior of a circle at the time when two chords intersect on the circle. Since the angles should be inscribed in the circle so here the angles should be added up to the 360 degrees same as like the circle also at the same time it should make the quadrilateral

Therefore, The missing information in the paragraph proof should be considered as the Inscribed Angle.

3*28 = 84 -10 = 74

74+56+50 = 180

180 degrees in a triangle

Answer:

∠ B = 60°

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

10x - 45 is an exterior angle of the triangle , then

10x - 45 = 3x + 4x = 7x ( subtract 7x from both sides )

3x - 45 = 0 ( add 45 to both sides )

3x = 45 ( divide both sides by 3 )

x = 15

Then

∠ B = 4x = 4 × 15 = 60°

Answer:

y = \(\frac{2}{3}\) x + 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = \(\frac{2}{3}\) , then

y = \(\frac{2}{3}\) x + c ← is the partial equation

to find c substitute (6, 5 ) into the partial equation

5 = \(\frac{2}{3}\) (6) + c = 4 + c ( subtract 4 from both sides )

1 = c

y = \(\frac{2}{3}\) x + 1 ← equation of line

Answer:

The value of the test statistic is -0.97

Step-by-step explanation:

This test is two tailed test.

Null and Alternative hypothesis is as follow

Null Hypothesis is used when it is assumed that there is no significant difference between the values.

Null Hypothesis = \(H_{0}\) = \(\mu =\) 59.8

The Alternative hypothesis is the alternative of the Null Hypothesis. It is an experimental technique that is used when it is assumed that there is some difference

Alternative Hypothesis = \(H_{a}\) = \(\mu \neq\) 59.8

Test statistcs is z

The value of test statistics can be calculated using the following formula

Test Statistics \(= (\bar x - \mu ) / \sigma / \sqrt n\)

Test Statistics \(= (59.7-59.8) / 1.3 / \sqrt 160\)

Test Statistics = -0.97

Answer:

The value is \(P( O \ and \ A ) = 0.583\)

Step-by-step explanation:

From the question we are told that

   The  number of apples is  \(A = 7\)

   The  number of oranges is  \(R = 5\)

Generally the probability that the bowl will be empty after the last apple  is taken from the box is mathematically represented as

  The probability that  5 oranges   and 7 apples are drawn in the 1st 11 draws

So

      \(P( O \ and \ A ) = \frac{(^5 C_5) * (^7 C_6) }{^{12} C_{11}}\)

Here C stands for combination hence we are going to be making use of the combination function in our calculators  

      \(P( O \ and \ A ) = \frac{(1 * 7 )}{12}\)

=> \(P( O \ and \ A ) = 0.583\)

Answer:

-5/4

Step-by-step explanation:

Let \((x_1,y_1)=(-4,4)\) and \((x_2,y_2)=(0,-1)\). The slope of the line would be:

\(\displaystyle \frac{y_2-y_1}{x_2-x_1}=\frac{-1-4}{0-(-4)}=\frac{-5}{4}=-\frac{5}{4}\)

Answer: -5/4

Step-by-step explanation:

To find the slope between two points, you can use the formula:

Slope = (y2 - y1)/(x2 - x1)

Using the points (0, -1) and (-4, 4), we can substitute the coordinates into the formula:

slope = (4 - (-1))/(-4 - 0)

slope = (4 + 1)/(-4)

slope = 5/-4

Therefore, the slope between the two points is -5/4.

The first quartile being 39 years old indicates a relatively younger age profile among the employees at CCNHS – Main Campus.

The first quartile (Q1) of the ages of the 256 employees of CCNHS – Main Campus being 39 years old implies that 25% of the employees have an age equal to or less than 39 years old.

To solve the problem, we need to understand the concept of quartiles. In statistics, quartiles divide a data set into four equal parts. The first quartile represents the point below which 25% of the data falls.

In this case, since the first quartile is 39 years old, it means that approximately one-fourth of the employees at CCNHS – Main Campus are 39 years old or younger.

This information provides insight into the age distribution of the employees. It suggests that there is a significant proportion of younger employees within the institution. Understanding the age demographics can be important for various purposes such as human resources planning, identifying generational differences, and designing age-appropriate policies or programs.

Overall, the first quartile being 39 years old indicates a relatively younger age profile among the employees at CCNHS – Main Campus.

The doubling time for continuously compounded interest is 69.3 years divided by the interest rate in %. Here, that is 69.3/7.3 = 9.49 years. That means an investment of 10 years will be slightly more than double the original amount. 2×65,000 = 130,000, so choice A is in the right ballpark. The other numerical choices are not.

Answer:

California

Step-by-step explanation:

The standard deviation of a sampling distribution also called standard error is obtained using the relation :

Standard Error = σ / sqrt(n)

Where n = sample size ; σ = population standard deviation

From the relation above, the higher the sample size of the sampling distribution, the lower the standard error because n is the denominator.

Therefore, California with a sample size of 1700 will have a lower standard error value Than Detroit with a sample size of 1000
