Answer:

3.2%

Step-by-step explanation:

I = prt

I = $13,536 - $12,000 = $1,536

1,536 = 12,000 × r × 4

r = 1,536/(12,000 × 4)

r = 0.032 = 3.2%

The volume of a sphere with radius 8 units is 2143.57 units³

What is a Sphere?

A sphere is symmetrical, round in shape. It is a three dimensional solid, that has all its surface points at equal distances from the center. It has surface area and volume based on its radius. It does not have any faces, corners or edges.

The Surface Area of a Sphere = 4πr²

The Volume of a Sphere = ( 4/3 ) πr³

where r is the radius of the sphere

Given data ,

Let the volume of the sphere be represented as A

Now , the value of A is

Let the radius of the sphere be r

The value of r = 8

Now , the formula to calculate the volume of the sphere is

Volume of a Sphere = ( 4/3 ) πr³

Substituting the values in the equation , we get

Volume of a Sphere = ( 4/3 ) x 3.14 x 8 x 8 x 8

Volume of a Sphere = ( 4/3 ) x 3.14 x 512

Volume of a Sphere = ( 4/3 ) x 1607.68

Volume of a Sphere = 2143.57 units³

Therefore , the value of A is 2143.57 units³

Hence , the volume of the sphere is 2143.57 units³

Apply Pythagorean theorem

Answer:

12 players

Step-by-step explanation:

the team started off with $1386.50

subtract $1137.50 for the rented bus

[tex]1386.50 - 1137.50 = 249[/tex]

the team has $249 left for the meals and a meal costs $20.75 for each player.

249 ÷ 20.75 = 12

[tex]\frac{1}{12}[/tex]

Step-by-step explanation:

The probability of picking a 3 is 1/4.

The probability of picking up a 1 the second time will be 1/3 since there will only be 3 cards left after the first time picking up the 3.

So 1/4 x 1/3 = 1/12

The difference of the sample means is statistically significant because it falls outside the 5% significance level.

The formula for a 95% confidence interval for the difference between two population means is:

(sample mean difference) ± (critical value) x (standard error of the mean difference)

Assuming a two-tailed test and a sample size greater than 30, the critical value is approximately 1.96. The standard error of the mean difference is calculated by dividing the standard deviation of the sample mean differences by the square root of the sample size.

So, the 95% confidence interval is:

1.74 ± 1.96 x (0.69/√n)

Assuming that the sample size is not given, we cannot calculate the exact confidence interval. However, we can say that the confidence interval will be of the form:

1.74 ± (some number)

Therefore, the 95% confidence interval is a range of values that contains the true population mean difference with 95% confidence.

Blank 1: -1.26

Blank 2: 3.44

In order to determine whether the difference is statistically significant, we need to compare the confidence interval to the null hypothesis of no difference. If the confidence interval does not contain the null hypothesis value, then we can reject the null hypothesis and conclude that the difference is statistically significant at the chosen significance level (5% in this case).

The null hypothesis in this case is that there is no difference between the population means. Since we are assuming this for the purpose of constructing the confidence interval, the null hypothesis value is 0.

The confidence interval in Part A does not contain the null hypothesis value of 0, since it ranges from -1.26 to 3.44. Therefore, we can reject the null hypothesis and conclude that the difference is statistically significant at the 5% significance level.

So, the correct answer is that the difference of the sample means is statistically significant because it falls outside the 5% significance level.

Step-by-step explanation:

Answer: Concave down

Explanation:

An example is shown below. We have the concave down parabola [tex]y = -x^2+7[/tex] marked in red. The trapezoidal sum is in blue. The three trapezoids combine to something just a bit smaller than the true area under the curve from x = -2 to x = 1. Therefore, this trapezoidal sum is an underestimate of the true area under the curve.

Every part of each trapezoid is completely below the red curve. In other words, no part of the blue pieces spill above the parabola.

Answer:

Below!

Step-by-step explanation:

1. Determining the y-intercept of the line:

The provided equation is in point slope form. To determine the slope and the y-intercept, we need to convert the equation to slope intercept form. Once it is converted to slope intercept form, the constant will be the y-intercept of the line. Start out by simplifying the distributive property on the R.H.S.

[tex]\implies y + 3 = 2 (x + 4)[/tex]

[tex]\implies y + 3 = (2x + 8)[/tex]

Now, open the parenthesis on the R.H.S

[tex]\implies y + 3 = 2x + 8[/tex]

If we take a look at the formula of slope intercept form (y = mx + b), we can see that "y" is isolated on the L.H.S. Thus, we need to subtract 3 both sides to isolate the y-variable.

[tex]\implies y + 3 - 3 = 2x + 8 - 3[/tex]

[tex]\implies y = 2x + 5[/tex]

We can see that the only constant in the equation is 5.

Therefore, 5 is the y-intercept.

2. Determining the slope of the line:

To determine the slope of the line, let's compare the formula with the equation obtained.

[tex]\implies (y = 2x + 5) \ = \ (y = mx + b)[/tex]

Thus, we obtain the following:

Thus, 2 is the slope of the line.

3. Plotting the line on the coordinate plane:

To graph the line on a coordinate plane, plot the y-intercept on the graph. The y-intercept is ALWAYS plotted on the y-axis.

Thus, the y-intercept plotted on graph is (0, 5).

Furthermore, plot a second point on the graph to draw a straight line through those points.

Determining the second point of the line:

If the slope of the line is 2, it means that the run (x) is 1 and the rise (y) is 2. Thus, we can add 1 to the x-coordinate of the y-intercept and 2 to the y-coordinate of the y-intercept.

Then, plot these points on the coordinate plane. Keep in mind that plot the x coordinate first, then the y-coordinate next. Once the coordinates are plotted, draw a line from the x-coordinate and another line from the y-coordinate. Finally, use your ruler and draw a line that passes through those two points. Your obtained graph is the graph of the line.

Answer:

4 weekdays and 2 weekends.

Step-by-step explanation:

6 days.

x = weekdays

y = weekends

7x = amount with weekdays

12y = amount with weekends

7x + 12y = 52, total

x + y = 6, amount of days

solve double variable equation

x = 6 - y, plug in to 1st equation

7(6 - y) + 12y = 52

42 - 7y + 12y = 52

5y = 10

y = 2 weekends

2 + x = 6

x = 4 weekdays
