The value of x is 1.56ft.
What is the Pythagoras theorem?The Pythagoras theorem states that the sum of the squares of the base and height is equal to the square of the hypotenuse of the right-angle triangle.
If p is the height, b is the base and h is the hypotenuse then according to the Pythagoras theorem
p²+b²=h²
Here given that the radius of the circle is r=2.1 ft
the perpendicular distance from the center of the circle to the line =1.4ft
that perpendicular line will bisect the line of length 2x.
Foe which each half of the line will be x.
Applying Pythagoras theorem in the right-angle triangle,
1.4²+x²=2.1²
⇒1.96+x²=4.41
⇒x²= 4.41-1.96
⇒x²= 2.45
⇒x= 1.56 ft
Therefore the value of x is 1.56ft.

In the card game Set, each card features a number of shapes, with four attributes:
Number: The number of shapes is 1, 2, or 3.
Color: Each shape is red, purple, or green.
Shape: Each shape is oval, diamond, or squiggle.
Shading: Each shape is hollow, shaded, or striped.
There is exactly one card for each possible combination of attributes.
In the game, several of the cards are dealt out, and the goal is to find a set. A set is formed by three cards, where for each attribute, either all three cards are the same, or all three cards are different. When three cards form a set, we can also count the number of attributes for which all three cards are the same.
(a) How many cards are in a complete deck of Set?
(b) How many unique sets are there?
(c) Find the number of sets where all three cards are the same for exactly 0 attributes.
(d) Find the number of sets where all three cards are the same for exactly 1 attribute.
(e) Find the number of sets where all three cards are the same for exactly 2 attributes.
(f) Find the number of sets where all three cards are the same for exactly 3 attributes.
Answers
A) The number of cards that are in a complete deck of Set is; 81
B) The number of unique sets are; 36
How to find the combination of a set of cards?a) We are given;
Number of shapes = 1, 2 or 3
Colour = Red, Purple or Green
Shape = Oval, Diamond or Squiggle
Shading = Hollow, Shaded or Striped
Now, since a set is formed by all 3 cards, then we can say that;
Number of cards in a complete deck of set = 3⁴ = 81 cards
(b) Let us first find all sets = 3² * 4 * 3 = 108.
Thus;
Unique sets = 108/3
= 36 unique sets.
(c) There are 3 ways to choose the number of the cards from the given order.
For the second one, there 2 choices, and then there is only 1 choice. Thus; Number of ways to choose the numbers = 3 * 2 * 1 = 6.
For the other attributes;
Number of ways = 6 * 6 * 24 *6 ways.
Now, since the order of cards doesn't matter in a set, then the number of sets where all three cards are the same for exactly 0 attributes is;
(6 * 6 * 24 *6)/3! = 864 sets
(d) If all the colors are the same, then;
Number of sets = 6 * 24 * 6/3! = 144 sets.
If all the numbers are the same, then there are 144 sets which is also same for shapes and shading. Thus;
The number of sets where all three cards are the same for exactly 1 attribute is; 4 * 144 = 576
(e) There are C(4, 2) = 6 ways of choosing two attributes.
For each of the two attributes, there are 3 options.
For the other two attributes, there are 3 ways of assigning the choices. Thus, number of sets = 6*3*3*3*3 = 486 sets.
(f) There are C(4,3) = 4 ways of choosing which attributes are the same. There are 3*3*4 = 36 ways to assign which is which for each of these three attributes, and there are 4 ways to assign the choices for the fourth attribute. Thus;
The number of sets where all three cards are the same for exactly 3 attributes = 4*36*4 = 576 sets.

The average waiting time to be seated for dinner at a popular restaurant is 23.8 minutes with a standard deviation of 6 minutes. What is the probability that 20 people will wait less than 21 minutes? Leave your answer exactly as it is taken from the table.
The probability that 20 customers will wait less than 21 minutes to be seated is
Answers
Using the normal distribution, it is found that there is a 0.3192 = 31.92% probability that 20 customers will wait an average of less than 21 minutes to be seated.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].The parameters for this problem are given as follows:
[tex]\mu = 23.8, \sigma = 6, n = 20, s = \frac{6}{\sqrt{20}} = 1.3416[/tex]
The probability that 20 customers will wait an average of less than 21 minutes to be seated is the p-value of Z when X = 21, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{21 - 23.8}{6}[/tex]
Z = -0.47
Z = -0.47 has a p-value of 0.3192.
0.3192 = 31.92% probability that 20 customers will wait an average of less than 21 minutes to be seated.

Answers
Answer:
y = 20°
x = 35°
Explanation:
Equation's:
1) 2y + x + 105° = 180°
2) 3x + x + 2y = 180°
Make y subject in equation 2
3x + x + 2y = 180
4x + 2y = 180
2y = 180 - 4x
y = 90 - 2x
Insert this into equation 1
2(90 - 2x) + x + 105° = 180°
180 - 4x + x + 105 = 180
-3x = -105
x = 35°
Find value of y
y = 90 - 2x
y = 90 - 2(35)
y = 20°
C+2y =75
X + 2y+ 3x =180
First solve for 2y and then substitute and you get 35 after that u plug it into the second one and u get 20

The vertices of A'B'C' if A(0, 10), B(8, 6), C(4, 2) is dilated by a scale factor of 2 are;
C. A'(0, 20), B'(16, 12), C'(8, 4)Which method can be used to find the vertices of A'B'C'?Given that triangle ABC is dilated by a scale factor of 2, we have;
A'B' = 2 × AB
A'C' = 2 × AC
B'C' = 2 × BC
Length of AB = √((8-0)^2 + (6-10)^2) = 4•√5
Length of AC = √((4-0)^2 + (2-10)^2) = 4•√5
Length of BC = √((8-4)^2 + (6-2)^2) = 4•√2
By multiplying the given coordinates by the scale factor, we have;
A' = 2 × (0, 10) = (0, 20)
B' = 2 × (8, 6) = (16, 12)
C' = 2 × (4, 2) = (8, 4)
A'B' = √((16-0)^2 + (12-20)^2) = 8•√5
A'C' = √((8-0)^2 + (4-20)^2) = 8•√5
B'C' = √((16-8)^2 + (12-4)^2) = 8•√2
Therefore when we have;

The dimensions of the circular cylinder of maximum volume inscribed in sphere is r = 20.4 cm , h = 28.86 cm.
What is a sphere ?A sphere is a three dimensional round shaped figure , It has no vertices and the distance form the centre to any point on the sphere is same.
It is given that
A right circular cylinder is inscribed in a sphere
The circular cylinder has the maximum volume
Radius of the sphere is 25 cm.
Dimensions of the cylinder = ?
As it is a right cylinder.
The Pythagoras theorem can be applied
r² + (h/2)² = 25²
r² = 625 - h²/4
volume of the cylinder
= πh(625 - h²/4)
= π(625 h - h³/4)
As the volume is maximum ,
so the derivative of the expression = 0
π(625 - 3h²/4) = 0
so h = 50 /√ 3
so r² = 625 - 2500 / (3 *4 )
r = 20.4 cm
h = 28.86 cm

2(6) + 2 = 14
Thus, n=6 satisfies
For n= 7
4(7) - 12 = 16
2(7) + 2 = 16
Thus, n=7 not satisfies
For n=8
4(8) - 12 = 20
2(8) + 2 = 18
Thus, n=8 not satisfies.
For n= 9

Find the sum of the first five terms of the geometric sequence: - 1, - 6, - 36
Answers
The sum of the first five terms of the geometric sequence is -1555
Sum of geometric sequenceThe formula for calculating the sum of geometric sequence is expressed as:
[tex]S_n=\frac{a(r^n-1)}{r-1}[/tex]
where
r is the common ratio = 6/1 = 6
a is the first term = -1
n = 5 (number of terms)
Substitute
[tex]S_5=\frac{-1(6^5-1)}{6-1}\\S_5=\frac{-7776+1}{5}\\S_5=-1555[/tex]
Hence the sum of the first five terms of the geometric sequence is -1555

The regression equation is calculated as: ŷ = -0.99299X + 26.39918
How to solve for the regression equationWe have these data for the x axis
12 15 20 22 15 8 6 17
These are the values for the y axis
17 15 6 7 6 18 21 7
Sum of X = 115
Sum of Y = 97
Mean X = 14.375
Mean Y = 12.125
Sum of squares (SSX) = 213.875
Sum of products (SP) = -212.375
Regression Equation = ŷ = bX + a
b = SP/SSX = -212.38/213.88 = -0.99299
a = MY - bMX = 12.13 - (-0.99*14.38) = 26.39918
ŷ = -0.99299X + 26.39918
These values where inputted into a regression analysis calculator and the output is ŷ = -0.99299X + 26.39918

In 1898, L. J. Bortkiewicz published a book called The Law of Small Numbers, where using data he collected for twenty years, he showed that the number of soldiers killed by horse kicks each year in the Prussian army followed a Poisson distribution with a mean of 0.61. What is the probability that there will be exactly three deaths in two years?
hurry please will pick brainly and step by step appreacite it
Answers
Answer:
given : 0.61 per year
formula poisson probability : p(x=k)=xke-x/k!
(a) The parameter λ is the product of the rate per year and the number of years. The number of years is 1 year in this case.
λ=0.61×1=0.61
Evaluate the formula of the Poisson probability at k=0,1:
P(X=0)= 0!
(0.61)
0
e
−0.61
≈0.5434
P(X=1)=
1!
(0.61)
1
e
−0.61
≈0.3314
Add the corresponding probabilities:
P(X≤1)=P(X=0)+P(X=1)=0.5434+0.3114=0.8748
Use the complement rule:
P(X>1)=1−P(X≤1)=1−0.8748=0.1252
Note: The solution in the back of the book is the probability of at least one death instead of more than 1 death, thus the solution in the back of the book is not correct.
