Answer:
9). x = 36.9°
10). x = 18.3°
Step-by-step explanation:
9). By applying tangent rule in the given triangle,
tan(x) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(x) = [tex]\frac{9}{12}[/tex]
x = [tex]\text{tan}^{-1}(\frac{3}{4})[/tex]
x = 36.87°
x = 36.9°
10). By applying sine rule in the given triangle,
sin(x) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(x) = [tex]\frac{11}{35}[/tex]
x = [tex]\text{sin}^{-1}(\frac{11}{35})[/tex]
x = 18.32
x ≈ 18.3°

The common ratio of the geometric sequence is r = 2.5
What is Geometric Progression?A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.
The nth term of a GP is aₙ = arⁿ⁻¹
The general form of a GP is a, ar, ar2, ar3 and so on
Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )
Given data ,
Let the terms of the GP be represented as A
Now , A = 1 , 2.5 , 6.25
where the common ratio = second term / first term
On simplifying , we get
r = 2.5 / 1
r = 2.5
Hence , the common ratio is r = 2.5

The probability of an event under the uniform distribution - random permutations. A class with n kids lines up for recess. The order in which the kids line up is random with each ordering being equally likely. There are two kids in the class named Celia and Felicity. Give an expression for each of the probabilities below as a function of n. Simplify your final expression as much as possible so that your answer does not include any expressions of the form (ab)(ab).
(a) What is the probability that Celia is first in line?
(b) What is the probability that Celia is first in line and Felicity is last in line?
(c) What is the probability that Celia and Felicity are next to each other in the line?
Answer:
a)
the probability that Celia is first in line is 1/n.
b)
the probability that Celia is first in line and Felicity is last in line is 1/n(n-1)
c)
the probability that Celia and Felicity are next to each other in the line is 2/n
Step-by-step explanation:
Given the data in question;
a) Celia is first in line?
the total ways are; n! to place n kids in n places in orderly fashion.
now, if Celia is the first kid, we have to order remaining n-1 kids
(n-1)! / n! = 1/n
therefore, the required probability is 1/n.
b) Celia is first in line and Felicity is last in line?
the total ways are; n! to place n kids in n places in orderly fashion,
now, if Celia is the first and Felicity is the last kid, we order the remaining n - 2 kids, which can be done in (n-2)!
(n-2)! / n! = 1 / n(n-1)
therefore, the required probability is 1 / n(n-1)
c) Celia and Felicity are next to each other in the line
the total ways are; n! to place n kids in n places in orderly fashion,
now, if Celia and Felicity as single object, so that they can be put together, we arrange n-1 objects which can be done in (n-1)! ways.
But also these 2 can change the place so in total there are 2(n-1)! ways.
2(n-1)! / n! = 2/n
Therefore, the required probability is 2/n
In ΔEFG, the measure of ∠G=90°, the measure of ∠E=6°, and GE = 3.3 feet. Find the length of EF to the nearest tenth of a foot.
Answer:
EF = 3.3 ft
Step-by-step explanation:
cos 6 = 3.3/EF
0.9945 = 3.3/EF
EF = 3.32 ft
a grocery store receives a shipment of 700 oranges the manager randomly selects 25 oranges to weigh. in that sample 2 oranges weigh 5 ounces. How many oranges in the shipment can the manager predict weigh 5 ounces
The number of oranges in the shipment can the manager predict weighing 5 ounces would be; 56.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The relations between variables, either direct or inversely proportional, can be built to find the desired measures in the problem.
Given that a grocery store receives a shipment of 700 oranges the manager randomly selects 25 oranges to weigh in that sample 2 oranges weigh 5 ounces.
Now set up a proportion;
2/25 = (x)700
Cross multiplication;
700(2)= 25(x)
1400/25=x
x=56
Therefore, the number of oranges in the shipment can the manager predicts weighing 5 ounces would be; 56.

List the key features of the quadratic function y = –x2 + 4x – 3.
The key features of the quadratic function are
vertex is (2, 1)Axis of symmetry: x = 2The domain of the function is the set of all real valuesDetermining the key features of the quadratic functionFrom the question, we have the following parameters that can be used in our computation:
y = -x² + 4x - 3
A quadratic function is represented as
y = ax² + bx + c
By comapring the equations, we have
a = -1, b = 4 and c = -3
For the key features
Axis of symmetry: x = -b/2a
So, we have
x = -4/(2 * -1)
x = 2
The domain of the function is the set of all real values
For the vertex, we have
(h, k) = (symmetry, f(symmetry))
So, we have
y = -2² + 4(2) - 3
y = 1
So, the vertex is (2, 1)

Step-by-step explanation:
First,let find the area of AMY. It is given that
Am=5
MY=7
AY=3
We can add up those numbers to find the perimeter.
5+7+3=15.
2. Since AMY and MEG are similar shapes, there side lengths are proportional, and their perimeter is also proportional.
The only transformation that can accomplish that is a dilation.
MEG is a dilation of AMY by 1/3. so that means MEG is 3 times smaller than AMY.
We would just divide 3 by the perimeter of AMY to find MEG.
[tex] \frac{15}{3} = 5[/tex]
