Answers
Answer:
The unique sequence of rigid motions that maps quadrilateral ABCD to EFGH are;
B. A reflection over the y-axis followed by a translation of (I, y) → (I, y - 6)
('I' is the image of 'x' after reflection)
Step-by-step explanation:
The coordinates of the vertices of the quadrilateral ABCD are;
A(-5, 4), B(-2, 4), C(-2, 1), and D(-5, 2)
The coordinates of the vertices of the quadrilateral EFGH are;
E(5, -2), F(2, -2), G(2, -5), and H(5, -4)
By analysis, we have;
The signs of the x-coordinate of the preimage and the image are opposite, therefore, one of the rigid motions is a reflection across the y-axis
Similarly, the common difference between the y-coordinate values of the image and the preimage are;
-2 - 4 = -6
-2 - 4 = -6
-5 - 1 = -6
-4 - 2 = -6
The common difference between the y-coordinates of the image and the preimage is -6, therefore, the y-values are obtained by a translation of y - 6 units
Therefore, the unique sequence of rigid motions that maps quadrilateral ABCD to EFGH are a reflection over the y-axis followed by a translation of (I, y) → (I, y - 6).

Answer:
1. 5000
2. the year is 2003
3. > 1000; evaluate the function
Step-by-step explanation:
1. The value of t is "years since 2005." In 2005, the value of t is zero. To find the model's prediction for 2005, substitute t=0.
p = 5000·2^0 = 5000·1
p = 5000 . . . . in 2005
__
2. When t=-2, it means you're concerned with the population 2 years before 2005. That is, you are modeling the population in 2003.
__
3. Evaluate the function for t=-2:
p = 5000·2^(-2) = 5000·1/4 = 1250
For t=-2, the fish population is 1250, which is more than 1000.

100 for the square
217.81 for the entire firgue
Step-by-step explanation:
For the square it's bh so do that formula
A = 10x10
A = 100
then for the semicircles that's half of a circle do the area of a circle formula and then multiply by half
A = 3.14×25
A = 78.54×0.5
A = 39.27
since we have 3 of them we are going multiply that by 3.
39.27 × 3 = 117.81
then we add them all up
117.81 + 100 = 217.81

How to calculate the volume of composite shapes?Composite shapes are made up of two or more shapes. According to the given question, the buoy is made up of a cone and sphere.
The volume of the buoy = volume of sphere + volume of the cone
Find the volume of the sphere
Vs = 4/3πr³
Vs = 4/3π(6)³
Vs = 288π cubic feet
Find the volume of the cone
Vc = 1/3πr²h
Vc = 1/3π(6)²(10)
Vc = 120π cubic feet
Volume of the buoy = 288π + 120π
V = 498π cubic feet
Therefore the required volume of the buoy in exact form is 498π cubic feet

Answers
Explanation:
In a study conducted by the US department of Health and Human Services, a sample of 546 boys aged 6-11 was weighed, and it was determined that 87 of them were overweighted. A sample of 508 girls aged 6-11 was also weighed, and 74 of them were overweighted. (a) Find a 90% confidence level for the difference of overweight proportion for aged 6 -11 between boys and girls. (b) Can you conclude that the proportion of overweight boys is higher than the proportion of girls who are overweight? i. State hypothesis. ii. Compute P-value. iii. What is your conclusion?
Answers
Answer:
a) CI = ( - 0,0087 ; 0,0355)
b) No CI contains 0 meaning that statistically the proportions could be equal
Step-by-step explanation:
Boys Sample
Size sample n₁ = 546
x₁ = 87
proportion p₁ = 87/546 p₁ = 0,159 p₁ = 15,9 %
Girls sample
Size sample n₂ = 508
x₂ = 74
proportion p₂ = 74 / 508 p₂ = 0,1456 p₂ = 14,56 %
Hypothesis test:
Null hypothesis H₀ p₁ = p₂
Alternative Hypothesis Hₐ p₁ ≠ p₂
Confidence Interval CI = 90 % significance level α = 10 %
α = 0,1 and as the alñternative hypothesis indicates is a two-tail test
then α/2 = 0,05
z(score) for 0,05 is from z table z(c) = 1,64
Confidence Interval 90 % is:
CI = [( p₁ - p₂) ± z(c) * √ p*q * ( 1/n₁ + 1 / n₂ )
p = (x₁ + x₂ ) / n₁ + n₂
p = ( 87 + 74 ) / 546 + 508
p = 0,1527 then q = 1 - 0,1527 q = 0,8473
CI = 0,0134 ± √ 0,1527*0,8473 ( 1/546 + 1 / 508 )
CI = 0,0134 ± 0,0221
CI = ( - 0,0087 ; 0,0355)
CI contains 0 meaning that difference between the groups could be 0
Therefore we can conclude that proportion on both groups are different. We can´t reject H₀
We need to calculate z(s)
z(s) = [ p₁ - p₂ ] / √ p*q * ( 1/n₁ + 1 / n₂ )
p = (x₁ + x₂ ) / n₁ + n₂
p = ( 87 + 74 ) / 546 + 508
p = 0,1527 then q = 1 - 0,1527 q = 0,8473
z(s) = [ 0,159 - 0,1456] / √ 0,1527*0,8473 ( 1/546 + 1 / 508 )
z(s) = 0,0134/ √0,1294 ( 0,0018 + 0,00196 )
z(s) = 0,0134/ √0,1294 ( 0,0038)
z(s) = 0,0134/ 0,0221
z(s) = 0,61
p-value for z(s) = 0,61 p-value = 0,7291
p-value > 0,05
As p-value is bigger than 0,05 we have to accept H₀. We don´t have enough evidence to claim any difference between the two groups
