The top of the hoodoo was approximately 25.5 meters above the level ground.

To solve this problem, we can use trigonometry and specifically the tangent function. We can create a right triangle with the hiker, the base of the cliff, and the top of the hoodoo as the vertices. The angle between the level ground and the line of sight to the top of the hoodoo is 69°, which is the angle opposite the height of the hoodoo. The distance from the hiker to the base of the cliff is the adjacent side of the triangle, which is 9.1m.

Using the tangent function, we can set up the following equation:

tan(69°) = height of hoodoo / 9.1m

We can then solve for the height of the hoodoo by multiplying both sides by 9.1m:

height of hoodoo = 9.1m * tan(69°)

Using a calculator, we get:

height of hoodoo ≈ 25.5m

Therefore, the top of the hoodoo was approximately 25.5 meters above the level ground.

Therefore, the 95% confidence interval for the population proportion of disks that are defective is (0.8357, 0.9475). This means that there is a 95% probability that the true population proportion of disks that are defective is between 0.8357 and 0.9475.

The quality-conscious disk manufacturer can use a 95% confidence interval to estimate the fraction of defective disks made by the company. The 95% confidence interval is calculated using the sample data to construct an interval estimate of the population proportion.
Using the given data, the sample proportion of disks that are not defective is 904/1015 = 0.8915.
The 95% confidence interval for the population proportion of disks that are defective is then given by:
Lower limit = 0.8915 – (1.96 x √(0.8915 x (1- 0.8915)/1015))
= 0.8915 – (1.96 x 0.0285)
= 0.8915 – 0.0558
= 0.8357
Upper limit = 0.8915 + (1.96 x √(0.8915 x (1- 0.8915)/1015))
= 0.8915 + (1.96 x 0.0285)
= 0.8915 + 0.0558
= 0.9475

Answer:

y= -1/2x - 2

Step-by-step explanation:

To change standard form to slope intercept form, bring the -x to the other side of the equation.

You'll have 2y=-4-x. Since there is no number on the -x, put a 1 on the front of it. (Not necessary). You'll have 2y= -4 -1x

Make y stand on its own. Divide the other side by 2.

You will end up with y= -1/2x -2

Nina pay in property taxes 501. or \(5.01*10^{2}\).

A property tax, often known as a millage rate, is an ad valorem tax based on a property's value. The tax is imposed by the administrative body of the region where the property is situated. This could be the federal government, a federated state, a county, a region of land, or a municipality. The average effective property tax rate in the Lone Star State is 1.60%, making Texas' property taxes the seventh-highest in the nation. Comparing that to the current 0.99% national average will help. Property taxes in Texas cost the average homeowner $3,797 a year.

Part A: To find the total surface area of the rectangular prism, we need to calculate the areas of all six faces and then add them together.

Given dimensions:

Length = 7 feet

Width = 3 feet

Height = 4.8 feet

Surface Area of each face:

Front and back faces: Length * Height

= 7 feet * 4.8 feet

= 33.6 square feet

Top and bottom faces: Width * Length

= 3 feet * 7 feet

= 21 square feet

Side faces: Width * Height

= 3 feet * 4.8 feet

= 14.4 square feet

Total Surface Area:

2 * (Front and back faces) + 2 * (Top and bottom faces) + 2 * (Side faces)

= 2 * 33.6 square feet + 2 * 21 square feet + 2 * 14.4 square feet

= 67.2 square feet + 42 square feet + 28.8 square feet

= 137 square feet

Therefore, the total surface area of the bench is 137 square feet.

Part B: To calculate the cost of covering the bench with ceramic tiles, we need to multiply the total surface area by the cost per square foot.

Cost per square foot = $0.89

Total Surface Area = 137 square feet

Total cost to cover the bench:

= Cost per square foot * Total Surface Area

= $0.89 * 137 square feet

= $121.93

Therefore, it will cost $121.93 to cover the bench with ceramic tiles.

Answer:

Of your choices, 87.5

Step-by-step explanation:

There may be a formula for figuring this out, but here's what I know how to do to solve this:

First we'll organize the data in ascending order:

3.9, 4.5, 5.7, 6.2, 7.4, 8.1, 8.4, 9.2  

The median is (6.2 + 7.4)/2 = 6.8

The first quartile is (4.5 + 5.7)/2 = 5.1

The third quartile is (8.1 + 8.4)/2 = 8.25

So the 75th percentile is 8.25

Since 9.2 is higher than that, I'd choose 87.5

Mildred's pie scored at the 87.5 percentile.

'A percentile is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations fall.'

According to the given problem,

Organizing the data in ascending order:

3.9 < 4.5 < 5.7 < 6.2 < 7.4 < 8.1 < 8.4 < 9.2  

Median of the given data = \(\frac{6.2+7.4}{2}\)

                                            = 6.8

First quartile = (4.5 + 5.7)/2

                      = 5.1

Third quartile = (8.1 + 8.4)/2

                       = 8.25

The third quartile is the 75th percentile,

⇒ 75th percentile = 8.25

Since, 9.2 > 8.25 , Mildred's pie scored at 87.5 percentile.

Hence, we can conclude, Mildred's pie scored at the 87.5 percentile.

Answer:

y=40x

Step-by-step explanation:

Answer:40

Step-by-step explanation:

The equation given is y = -6 + 1. To find a solution for this equation, we need to substitute different values for x and evaluate the corresponding value of y.

However, it seems that there is a typographical error in the equation. The equation y = -6 + 1 simplifies to y = -5. Therefore, the equation does not have any variables or unknowns to solve for.

In this case, any value of y that is equal to -5 will satisfy the equation.

For example, the ordered pair (x, y) = (2, -5) would be a solution, as y is equal to -5. Similarly, (x, y) = (0, -5) or (x, y) = (-3, -5) would also be solutions, as long as y remains equal to -5.

In summary, the equation y = -6 + 1 simplifies to y = -5, and any ordered pair with a y-coordinate of -5 would be a solution to this equation.

Answer: (a) Jaclyn's reasoning is incorrect because she used the property that the square root of a product is equal to the product of the square roots. However, this property only holds true for non-negative numbers. In this case, Jaclyn used the square root of 25 to calculate the square root of 75, but 75 is not a perfect square, so its square root is not a rational number.

(b) To estimate the square root of 75, we can use a calculator or simplify the expression by factoring out perfect squares. We can factor 75 as 25 x 3, so

√75 = √(25 x 3) = √25 x √3 = 5√3 ≈ 8.7

Therefore, the square root of 75 to the nearest tenth is approximately 8.7.

Answer:

The pizza parlors cost the same when delivering 4 pizzas.

Step-by-step explanation:

For each store, the total price is

cost of pizzas + cost of delivery

The cost of delivery is just a fixed number for each store, $20 or $12.

The cost of the pizzas is the price of a pizza multiplied by the number of pizzas.

Let x = number of pizzas

The cost of the pizzas is

Jacob's: 10x

Ashley's: 12x

Jacob's total cost (pizzas + delivery):

10x + 20

Ashley's total cost (pizzas + delivery):

12x + 12

We want the total costs to be the same, so we set our two total cost expressions equal and solve for x.

12x + 12 = 10x + 20

Subtract 10 from both sides.

2x + 12 = 20

Subtract 12 from both sides.

2x = 8

Divide both sides by 2.

x = 4
