Lisa walked from south Pier to the North Pier along the beachfront. Deanna walked from the South Pier to the North Pier along Harbor Drive and Park Street. Which statement best describes the distances the two women walked?

The probability that at least one trip will travel before Isabella was born is 0.9999, or 99.99% (rounded to the nearest hundredth).

We can use the complement rule to find the probability that at least one trip will travel before Isabella was born. The complement rule states that the probability of an event happening is equal to 1 minus the probability of the event not happening. In this case, the event we are interested in is at least one trip traveling before Isabella was born.

The probability of none of the 555 trips traveling before Isabella was born is (1-0.25) raised to the power of 555, since the probability of each trip not traveling before Isabella was born is 1 - 0.25 = 0.75.

So, the probability of at least one trip traveling before Isabella was born is:

P(at least one before she's born) = 1 - (1-0.25)^{555}

P(at least one before she's born) = 1 - 0.75^{555}

P(at least one before she's born) = 0.9999 (rounded to the nearest hundredth)

Therefore, the probability that at least one trip will travel before Isabella was born is 0.9999, or 99.99% (rounded to the nearest hundredth).

Fraction value [tex]16\frac{17}{27}[/tex] as a decimal is 16.629629

Percentage, decimal, and fraction are all ways of representing numbers that are related to each other. Here's a brief explanation of each:

Percentage: A percentage is a number expressed as a fraction of 100, with the symbol % (percent) added. For example, 50% is the same as 50/100 or 0.5.

Decimal: A decimal is a way of representing fractions using the base-10 numbering system. It is written with a decimal point between the whole number and the fractional part. For example, 0.5 is the same as 5/10 or 50/100 or 50%.

Fraction: A fraction is a way of representing a part of a whole or a ratio of two numbers. It is expressed as a ratio of two integers, with the numerator (top number) representing the number of parts being considered, and the denominator (bottom number) representing the total number of equal parts. For example, 1/2 is the same as 0.5 or 50%.

The angles (x + 7)° and (3x - 21)° are vertical angles and the value of x is equal to 14.

Vertical angles also called vertically opposite angles are formed when two lines intersect each other, the opposite angles formed by these lines are vertically opposite angles and are equal to each other.

so we shall solve for x and y as follows:

3x - 21 = x + 7

3x - x = 21 + 7 {collect like terms}

2x = 28

2x/2 = 28/2 {divide through by 2}

x = 14

The 8 students at the pizza party ate 2 and 2/3 pizzas if each student ate 1/3 of a pizza.

If each of the 8 students ate 1/3 of a pizza, we can find the total number of pizzas by multiplying the number of students by the fraction of a pizza each student ate:

8 students × 1/3 pizza per student = 8/3 pizzas

However, it's more common to express the result as a mixed number or decimal. To convert the improper fraction 8/3 to a mixed number, we can divide the numerator by the denominator:

8 ÷ 3 = 2 with a remainder of 2

Therefore, the students ate 2 and 2/3 pizzas altogether. Alternatively, we can convert the improper fraction to a decimal by dividing the numerator by the denominator:

8/3 = 2.67

Therefore, the students ate approximately 2.67 pizzas altogether.

To recap, if each of the 8 students at the pizza party ate 1/3 of a pizza, they ate 8/3 pizzas altogether, which is equal to 2 and 2/3 pizzas or approximately 2.67 pizzas.

Answer:

Step-by-step explanation:

To find the volume of a sphere, we use the formula:

V = (4/3) * π * r^3

where r is the radius of the sphere.

We are given that the radius of the sphere is 7 cm and we can use 3 as an approximation for π. Substituting these values in the formula, we get:

V = (4/3) * 3 * 7^3

V = (4/3) * 3 * 343

V = 4 * 343

V = 1372

Therefore, the volume of the sphere is 1372 cubic centimeters.

The margin of error for a sample mean at a 95% confidence level can be calculated using the formula

a) True. This is an example of sampling without replacement because once a person is selected for jury duty, they are no longer available for selection again.

b) 0.5238 is the probability.

a) Sampling without replacement is the technique of choosing a sample from a population without replacing the selected individuals in the population after each selection. In this case, once an eligible person is chosen, they cannot be chosen again.
Hence, the given statement is true.

b) We have to find the probability of all four of the excused jurors being women. We are picking four people out of 70 men and 80 women, or 150 people in total. Since we are dealing with independent events, we may use the multiplication principle for probabilities.
There are 80 women in the 150-person sample, so the probability of selecting one woman is 80/150.
After the first woman is selected, there are 79 women remaining in the 149-person sample, so the probability of selecting another woman is 79/149.
Similarly, the probabilities of selecting a third and fourth woman are 78/148 and 77/147, respectively.

Therefore, the probability that all four excused jurors are women is:
P(4 women) = (80/150) × (79/149) × (78/148) × (77/147)
P(4 women) = 0.5238 (rounded to four decimal places)
The probability that all four of the excused jurors are women is 0.5238.

If  she can make 7 bags in one day, the percent increase in the number of bags Hannah can make is 75%.

To calculate the percent increase in the number of bags Hannah can make, we need to find the difference between the number of bags she can make now and the number she could make before, and then express this difference as a percentage of the original number of bags she could make.

The difference between the number of bags she can make now and the number she could make before is:

7 bags - 4 bags = 3 bags

To express this difference as a percentage of the original number of bags she could make, we can use the following formula:

percent increase = (difference ÷ original value) x 100%

In this case, the original value is 4 bags, so we have:

percent increase = (3 bags ÷ 4 bags) x 100% = 75%

This means that she can now make 75% more bags per day than she could before she got her new sewing machine.

Step-by-step explanation:

Since Lourdes garage is in the shape of a square pyramid, the surface area of the square pyramid roof is 1440 ft²

An equation is an expression that shows how two or more numbers and variables are related using mathematical operations of addition, subtraction, multiplication, division, exponents and so on.

The surface area (SA) of a pyramid is given as:SA = B + (1/2)Ph

where B is the base area, P is the perimeter and h is the slant height

Since the roof is a square pyramid with base 40 feet and slant height of 18 ft, hence:

h = 18 ftP = 40 + 40 + 40 + 40 = 160 ft.

Surface area of only roof = (1/2)Ph

Therefore, Substituting:

SA = (1/2)(160)(18) = 1440 ft²

The value of t such that the area under the curve between 1 and 11 equals 0.95, assuming the degrees of freedom is 8, is 1.86.

Degree of freedom refers to the number of independent variables that can be varied in a statistical experiment or analysis. It is a measure of the flexibility of the experiment or analysis to accommodate new data or observations.

In this case, the degrees of freedom is 8. To find the t-value, the t-table must be consulted. The t-table is a chart of t-values for different degrees of freedom. The t-value is the value at which the area under the curve between 1 and 11 equals 0.95. The t-table is organized such that the rows represent the degrees of freedom and the columns represent the area under the curve. For example, if the degrees of freedom is 8 and the area under the curve is 0.95, the t-value can be found in the row for 8 degrees of freedom and the column for 0.95 area under the curve. The t-value from the t-table in this case is 1.86.

Therefore, the value of t such that the area under the curve between 1 and 11 equals 0.95, assuming the degrees of freedom is 8, is 1.86.

Answer: The given quadratic expression is:

9x² - 14x + 16

To factorize it, we can use the quadratic formula:

x = [-(-14) ± √((-14)² - 4(9)(16))] / 2(9)

Simplifying under the square root:

x = [-(-14) ± √(4)] / 18

x = [14 ± 2] / 18

x = (16/18) or x = (12/18)

Simplifying:

x = (8/9) or x = (2/3)

So the roots of the quadratic are x = 8/9 and x = 2/3. Therefore, we can factorize the quadratic expression as:
