There are 10,000 possible codes that can be entered into the keypad to open the garage.
Explanation:The number of possible codes is determined by the number of choices for each digit of the code. In this case, there are 10 possible choices for each digit (0-9). Since there are 4 digits in the code, we can multiply the number of choices for each digit together to find the total number of possible codes: 10 x 10 x 10 x 10 = 10,000. Therefore, there are 10,000 possible codes that can be entered into the keypad to open the garage.

Probability help please? In a certain instant lottery game, the chances of a win are stated as "1 in 19." Express the indicated degree of likelihood as a probability value between 0 and 1 inclusive. (round to three decimal places) I am confused and need a step by step instructions. Please help
Final answer:
To convert the chances of a '1 in 19' win into a probability value, you divide 1 by 19 to get 0.05263 and then round to 0.053. Therefore, the lottery win probability is 0.053.
Explanation:
To express the likelihood of a win in a lottery game as a probability value between 0 and 1, when the chances of a win are stated as "1 in 19", you follow these steps:
Understand that "1 in 19" means there is one chance to win for every 19 trials, so the total number of possible outcomes is 19 (18 losses + 1 win).
Express the chance to win as a fraction with the number of wins (1) over the total number of potential outcomes (19).
Convert the fraction into a decimal by dividing the numerator (1) by the denominator (19), which gives you approximately 0.05263.
Round the result to three decimal places, as requested, which gives you a probability value of 0.053.
Therefore, the probability of winning the lottery game is 0.053.

Kit folds a bandana diagonally before tying it around her head. The side length of the bandana is 16 in. About how long is the diagonal?
The length of the diagonal of Kit's bandana tied around her head is approximately 22.63 inches long.
Kit folds a bandana diagonally.
To find the length of the diagonal (hypotenuse of a right triangle), we can use the Pythagorean theorem.
The bandana side length (a) is 16 in.
Let x be the length of the diagonal.
Using a^2 + a^2 = x^2, we get 16^2 + 16^2 = x^2. Solving this gives x ≈ 22.63 in.
Find all complex solutions of x^2+5x-5=0.
(If there is more than one solution, separate them with commas.)
The complex solutions of x^2+5x-5=0 are (-5 + √45)/(2) and (-5 - √45)/(2).
Explanation:To find the complex solutions of x2+5x-5=0, we can use the quadratic formula:
x = (-b ± √(b^2 - 4ac))/(2a)
Substituting the values a=1, b=5, and c=-5 into the formula, we get:
x = (-5 ± √(5^2 - 4(1)(-5)))/(2(1))
Simplifying further,
x = (-5 ± √(25 + 20))/(2)
x = (-5 ± √(45))/(2)
Since the square root of 45 cannot be simplified, we can write the solutions as:
x = (-5 ± √45)/(2)
Therefore, the complex solutions to the equation x2+5x-5=0 are:
x = (-5 + √45)/(2), (-5 - √45)/(2)

Mia's perents said that she can use a space in the yard that measures. 13 feet long by 9 feet wide for her wildflower garden. What is the area of the garden
The area of 13 feet long by 9 feet wide wildflower garden is 117 square feet.
Use the concept of a rectangle defined as:
Rectangles are four-sided polygons with all internal angles equal to 90 degrees. At each corner or vertex, two sides meet at right angles. The rectangle differs from a square in that its opposite sides are equal in length.
To find the area of her garden,
Multiply the length and width of the space.
In this case,
the length is 13 feet and the width is 9 feet.
So, the area of Mia's garden would be,
13 feet x 9 feet = 117 square feet.
Hence,
The area of the garden is 117 square feet.

Line segment AB has a length of 3 units. It is translated 2 units to the right on a coordinate plane to obtain line segment A prime B prime. What is the length of A prime B prime?
A. 1 unit
B.2 units
C. 3 units
D. 5 units
Answer:
The correct option is C.
Step-by-step explanation:
It is given that line segment AB has a length of 3 units. It is translated 2 units to the right on a coordinate plane to obtain line segment A'B'.
Translation is a rigid transformation. It means the shape and size of preimage and image are same. In other words we can say that the preimage and image are congruent.
Corresponding sides of congruent figures are congruent.
[tex]AB\cong A'B'[/tex]
[tex]AB=A'B'[/tex] (Definition of concurrent segment)
[tex]3=A'B'[/tex] (AB=3 units)
The length of A'B' is 3 units. Therefore the correct option is C.
The population of a local species of flies can be found using an infinite geometric series where a1 = 940 and the common ratio is one fifth. write the sum in sigma notation, and calculate the sum (if possible) that will be the upper limit of this population.
A. Sigma notation
The formula for finding the nth value of the geometric series is given as:
an = a1 * r^n
Where,
an = nth value of the series
a1 = 1st value in the geometric series = 940
r = common ratio = 1/5
n = nth order
The sigma notation for the sum of this infinite geometric series is therefore,
(see attached photo)
B. Sum of the infinite geometric series
The formula for calculating the sum of an infinite geometric series is given as:
S = a1 / (1 – r)
Substituting the given values:
S = 940 / (1 – 1/5)
S = 1,175
Square sandbox with sides 3 feet long. She wants to put sand 0.85 feet deep in the box. What is the exact measure, in cubic feet of sand, tat Maija needs?
To find the volume of sand needed for Maija's sandbox, multiply the length, width, and depth. As the sandbox is a square, both the length and width are 3 feet. The depth is 0.85 feet. Thus, Maija needs 7.65 cubic feet of sand.
Explanation:This question is about calculating volume, specifically the volume of sand that Maija needs for her sandbox. The volume of a box is calculated by the formula: volume = length x width x height. Since the sandbox is square, the length and width are both 3 feet. The height, or in this case, the depth of the sand, is 0.85 feet.
Therefore, the volume of sand needed is calculated as follows: Volume = 3 ft x 3 ft x 0.85 ft = 7.65 cubic feet. So, Maija needs exactly 7.65 cubic feet of sand for her sandbox.

The diagonals are 3 cms long each. The area of the kite in the given figure is 9 [tex]cm^2[/tex].
Mathematically, a quadrilateral with two pairs of adjacent sides that are congruent (have equal length) is termed a "kite". Note that not all quadrilaterals with congruent adjacent sides are kites. Kites have numerous applications in geometry, including the study of polygons, symmetry, and angles. They can be used to solve geometric problems and to analyze relationships between sides, angles, and diagonals within the quadrilateral.
Given that the length of the diagonals = 3 cm.

Help identify!!!! ADB
The value of angle ADB in the triangle ADB is determined as m∠ ADB = 95⁰. (Option A).
How to calculate angle ADB?
The value of angle ADB is calculated by applying intersecting chord theorem and principle of sum of angles in a triangle.
The intersecting chord theorem states that the angle at tangent is half of the arc angle of the two intersecting chords.
So the value of angle A is calculated as follows;
m ∠ BAC = ¹/₂ x arc BC
m ∠ BAC = ¹/₂ x 110
m ∠ BAC = 55
The value of angle ADB is calculated as follows;
m ∠ ABD + m ∠ ADB + m ∠ BAD = 180 (sum of angles in a triangle)
30 + m ∠ ADB + 55 = 180
m ∠ ADB + 85 = 180
m ∠ ADB = 180 - 85
m ∠ ADB = 95⁰

Write the sum using summation notation, assuming the suggested pattern continues. -8 - 3 + 2 + 7 + ... + 67
The correct answer is [tex]\sum_{n=1}^{20} (-8 + 5(n-1))[/tex]
The sum using summation notation, assuming the suggested pattern continues, can be written as:
[tex]\sum_{n=1}^{20} (-8 + 5(n-1))[/tex]
[tex]-8 - 3 + 2 + 7 + \ldots + 67 = \sum_{n=1}^{20} (-8 + 5(n-1))[/tex]
Explanation:
- The pattern appears to be an arithmetic progression with a common difference of 5.
- The first term is -8, and the common difference is 5.
- The nth term of an arithmetic progression can be expressed as [tex]a_n = a_1 + (n-1)d[/tex], where [tex]a_1[/tex] is the first term, and [tex]d[/tex] is the common difference.
- Substituting [tex]a_1 = -8[/tex] and [tex]d = 5[/tex], we get [tex]a_n = -8 + 5(n-1)[/tex].
- The sum of the first 20 terms of this arithmetic progression can be represented using the summation notation, with the index [tex]n[/tex] ranging from 1 to 20.
Therefore, the sum using summation notation is [tex]\sum_{n=1}^{20} (-8 + 5(n-1))[/tex].
