The Leader of Zip decrees that the digit 0, since it represents nothing, will no longer be used in any counting number. Only counting numbers without 0 digits are allowed. So the counting numbers in Zip begin 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12, . . . , where the tenth counting number is 11. When you write out the first one thousand allowable counting numbers in Zip, what are the last three digits of the final number?
The last three digits of the final number are 109.
A number is an arithmetic value that is used to calculate and represent a quantity.
The digit zero will no longer be utilized in any counting numbers, according to the Leader of Zip, since it stands for nothing. There can only be counting numbers with 1 digit.
From 1 to 11,
11 is the tenth counting number.
So for the case of first 1000 numbers,
Number of permutations =1000/10 =100
Since 101 to 109 contains a zero.
So, 100+9=109
So, 1000+109=1109
Thus, the last number is 1109, and its last three digits are 1,0,9.

Sean tried to drink as fast as he could. He drank the slushy at a constant rate. There were originally 275 milliliters of slushy in the cup. After 13 seconds, 210 milliliters of slushy remained. (Please help and explain.)
How fast did Sean drink?
How long did it take Sean to drink all the slushy?
The rate at which Sean drank the slushy is 5 milliliters per second.
The time it would take to drink all the slushy is 55 seconds.
How fast did Sean drink?In order to determine the speed at which the slushy was drank, divide the slushy drank in 13 seconds by 13 seconds.
Speed = slushy drank in 13 seconds / time
(275 - 210) / 13
65 / 13 = 5 milliliters per second
Time it would take to drink all the slushy =total milliliters of the slushy / speed

The tree diagram represents an experiment consisting of two trials
P(D)=?
For the given tree diagram of the experiment consisting of two trials, P(D) = 0.74
A method that can be infinitely repeated and has a clearly defined range of potential outcomes, or sample space, is referred to as an experiment or trial in probability theory. If there are multiple possible outcomes from an experiment, it is considered to be random; if there is just one, it is said to be deterministic.
Calculation of P(D) for the given experiment:
From the first branch of the tree, P(D) = 0.7 × 0.6
P(D) = 0.42
From the second branch of the tree, P(D) = 0.8 × 0.4
P(D) = 0.32
Hence, the probability of getting D in the experiment is,
P(D) = P(D) from first branch of the tree + P(D) from the second branch of the tree
P(D) = 0.42 + 0.32

(1)[3 Pts] The probability of producing a high-quality color print is 0.10. How many prints do you have to produce so that the probability of producing at least one quality print is larger than 0.90
The number of prints that the probability of producing at least one quality print is 22.
Given that the probability of producing a high-quality color print is 0.10.
The binomial distribution summarizes the number of trials or observations when each trial has an equal chance of reaching a certain value. The binomial distribution determines the probability of observing a particular number of positive results in a defined number of tests.
Probability of high-quality color print (P) = 0.1
Probability of producing not high-quality color print (1-P) = 0.9
Assume the no. of prints to produce 'n' and these are produced independently say 'x' be the no. of producing quality prints, which follows a binomial distribution.
The probability function of binomial distribution is
[tex]P(X=x)\left(\begin{array}{l}n\\ x\end{array}\right)P^x(1-P)^{n-x},x=0,1,2,.....,n[/tex]
Given that
P(X≥1)≥0.90
1-P(X=0)≥0.90
1-(1-P)ⁿ≥0.90
1-(0.90)ⁿ≥0.90
(0.90)ⁿ≥0.10
Now, taking log of both sides, we get
nlog(0.90)≥log(0.10)
n(0.1053)≥2.3025
n≥21.86

What is linear equation ?
A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.The cost of magazines =
3.95(3) + 8.95b = 47.65
11.85 + 8.95b = 47.65

Find Q2 of the following data set 3, 9, 12, 4, 6, 40, 25, 14, 10
Answer:
Q₂ = 10
Step-by-step explanation:
Given data set: 3, 9, 12, 4, 6, 40, 25, 14, 10
Q₂ is the median (the middle value) of the given data set when the data set is ordered from smallest to largest.
Order the values in the data set:
3, 4, 6, 9, 10, 12, 14, 25, 40
As the number of values is odd, the middle value is the 5th value.
Therefore, the median (Q₂) of the given data set is 10.
If the number of data values is even, and therefore there are two middle values, the median is halfway between them.
Find the surface area of the composite figure. Round your answer to the nearest tenth if necessary.
The surface area of the composite figure is 444m².
Given a composite figure which is shown in the question.
The area of a shape (in square units) is the number of unit squares required to cover the entire area without gaps or overlaps. If a hologram has planes, those faces are called faces.
Firstly, we will find the area of front and end triangles by using the formula
Area=(1/2)×b×h and we will multiply this area by 2 because we are finding the area of two same triangles.
Here, h=6 and b=16 and substitute these values in the formula, we get
A₁=2×(1/2)×16×6
A₁=2×8×6
A₁=96m²
Now, we will find the area of the left and right side rectangles which joined both the triangles.
We will find the area by using the formula Area=l×b and we will multiply this area by 2 because we are finding the area of two same rectangles.
here, l=10 and b=5 and substitute these values in the formula, we get
A₂=2×10×5
A₂=100m²
Further, we will find the area of the front and end side rectangles that joined both by the base of the triangles.
We will find the area by using the formula Area=l×b and we will multiply this area by 2 because we are finding the area of two same rectangles.
here, l=16 and b=4 and substitute these values in the formula, we get
A₃=2×16×4
A₃=128m²
Furthermore, we will find the area of the left and right side rectangles which joined by the front and end rectangles.
We will find the area by using the formula Area=l×b and we will multiply this area by 2 because we are finding the area of two same rectangles.
here, l=4 and b=5 and substitute these values in the formula, we get
A₄=2×4×5
A₄=40m²
Now, we will find the area of the base of the composite figure which is rectangle.
We will find the area by using the formula Area=l×b.
here, l=16 and b=5 and substitute these values in the formula, we get
A₅=16×5
A₅=80m²
So, the surface area of the given composite figure will be
Surface area=A₁+A₂+A₃+A₄+A₅
Surface area=96m²+100m²+128m²+40m²+80m²
Surface area=444m²
Hence, the surface area of the given composite figure is 444m².

A client has just inherited a property. the deed is quite old, but she knows where the front two corners of the property are and that the distance between them is 210 feet. the shape is an irregular quadrilateral and the other three sides have distances of 515 feet, 232 feet, and 542 feet in a clockwise direction from the front left corner. more importantly, it is known that the front left corner of the property is a right angle.
This exercise involves the construction of a blueprint. To do so, we need to solve for angles using the Cos Rule. See the step by steps procedure below.
What is a blueprint?A blueprint is a masterplan that highlights how a structure will be look like when it is completed.
What is the solution to the above blueprint?Let the dimensions of the property be labelled QRST.Recall that the distance between the two corners are QR = 210 ftOther sides are: 515ft, 232ft, and 542ft going in a clockwise direction.Recall that the front left corner of the property is a right angle.From the above, see attached the first simple quadrilateral QRST (Draft I) that is indicates the above information.
Next Step
We have to derive ∠T, ∠ S, and ∠R.
In order to achieve the above, we must split the quadrilateral into two triangles.
As noted in the image, the quadrilateral is bisected from R to T.
∠R and ∠T are also divided into R1 R2 and T1, T2 respectively.
Next step - Derive ∠T1 and ∠R1 .
To do the above, we must deploy the Pythagoras Theorem. (PT)
PT requires:
TR² = QT² + QR²
TR² = (210)² + (515)²
TR² = 44,100 + 265,225
TR² = 309,325
TR = √309,325
TR = 556.17
Next step, Derive T1
We can derive T1 using the cos rule:
Cos T1 = QR/QT
= 515/556.17
Cos T1 = 0.926
Therefore
T1 = Cos⁻¹(0.926)
T1 = 22.18°
Next we derive R1
R1 = 180° - (90° + 22.18°)
R1 = 67.82°
In ΔTRS, by using Cosine Rule,
Cos T2 = [TS² + QR² - RS²]/2(TS) * (TR)
Cos T2 = [(232)² + (556.16)² - (542)²]/ 2 * (232) x (556.16)
Cost T2 = 69,373.945/258,058
Cost T2 ≈ 0.269
Therefore,
T2 = Cos⁻¹(0.269)
T2 ≈ 74.4°
Applying the same process, we can derive R2
Cos R2 = TR² + RS² - TS²
Cos R2 = [(556.16)² + (542)² - (232)²] / 2 (556.16) * (542)
Cost R2 = 0.911
R2 = Cos ⁻1 (0.911)
R2 = 24.34°
From the above, we can execute the following iterations:
∠S = 180° - (R2 + T2)
= 180 ° - (24.34 + 74.4)
∠C = 81.26°
Likewise:
∠R = R1 + R2
= 67.82 + 24.34
∠B = 92.16°
Lastly:
∠T = T1 + T2
= 22.18 + 74.40
∠T = 96.48°

a = 1
b = 11
c = 1
b^2-4ac = 11^2-4*1*1 = 117
So this equation has two solutions:
x = (-b -/+ √(b^2-4ac) ) / 2a
x = (-11 -/+ √(117) ) / 2
x = (-11 -/+ 3√(13))/ 2
