Since the budget exceeded by $177, the initial budget must have been $1300 (which is 100%).

Calculating 1% of the $1300 budget yields $13.

Next, we divide the excess of $177 by $13 to determine the percentage.

177:13 = 13.61%

Rounding gives us a 14% excess over the budget.

AnnZ [12381]
Utilizing the specified equation,
                              V = lwh
The volume for the prism illustrated is given by,
                              V = (x² - x / 4x + 1) (2x - 5)(24x² + 6x / x - 1)
By means of factoring,
                            V = ((x)(x - 1) / (4x + 1))(2x - 5)((6x)(4x + 1) / (x - 1))
By removing identical terms from both the numerator and the denominator,
                           V = (x)(2x -5)(6x)

The line segments of a cube include edges, the diagonals of the faces, and the diagonals through the interior of the cube. Which
lawyer [12517]
The diagonal that crosses the interior of the cube is the longest segment. The hypotenuse corresponds to the longest side in a right triangle. In this case, the cube's diagonal serves as the hypotenuse of a right triangle, with the legs being the diagonal of one of its faces and one of its edges. The edges are the shortest sections and function as the legs of a right triangle where the face's diagonal acts as the hypotenuse.

A 95% confidence interval for the population proportion of professional tennis players who earn more than 2 million dollars a ye
Svet_ta [12734]

Response:

e. 545

Detailed explanation:

In a survey sample containing n individuals, with a success probability of \pi, and a confidence level of 1-\alpha, the ensuing confidence interval for proportions is established.

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

Wherein

z denotes the z-score corresponding to a probability value of 1 - \frac{\alpha}{2}.

For this scenario, we find:

The estimate averages the two bounds. Thus \pi = \frac{0.82+0.88}{2} = 0.85

95% confidence level

Consequently, z represents the z value corresponding to the p-value of 1 - \frac{0.05}{2} = 0.975, hence Z = 1.96.

The lower boundary of this interval is:

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

In this query, L = 0.82. Therefore

0.82 = 0.85 - 1.96\sqrt{\frac{0.85*0.15}{n}}

1.96\sqrt{\frac{0.85*0.15}{n}} = 0.03

0.03\sqrt{n} = 1.96\sqrt{0.85*0.15}

\sqrt{n} = \frac{1.96\sqrt{0.85*0.15}}{0.03}

(\sqrt{n})^{2} = (\frac{1.96\sqrt{0.85*0.15}}{0.03})^{2}

n = 544.23

Thus, the accurate response is:

The Freeman family is barbecuing veggie burgers, corn cobs, and mushroom caps in their local park. If 3/8 of the items barbecued
AnnZ [12381]

Answer:

7/24

Step-by-step explanation:

All the items being grilled collectively equal 1.

Each item represents a fractional portion of 1.

Combine 3/8 and 1/3, then subtract that sum from 1.

3/8 + 1/3 = 9/24 + 8/24 = 17/24

This means that veggie burgers and corn contribute to 17/24 of the total.

To determine the fraction accounted for by mushrooms, we take 1 and subtract 17/24.

1 - 17/24 = 24/24 - 17/24 = 7/24.

Final answer: 7/24
