Answer:
x = 1,650
Step-by-step explanation:
A real-world problem with a sample and a population is modeled by the proportion 66/100=x/2,500. Use the proportion to complete the sentences.
From the above question, we have to solve for x
Hence, we have the proportion
66/100=x/2,500
Cross Multiply
100 × x = 66 × 2,500
x = 66 × 2,500/100
x = 1,650

Answer:
Option C is right.
Step-by-step explanation:
Given is a graph with two triangles marked on it.
Triangle ABC is in the I quadrant with vertices (2,2) (2,10) and (8,12)
Triange A'B'C' is in the III quadrant with vertices (-1,-1), (-1,-5) and (-4,-6)
On comparison we find corresponding side of AB is A'B'
Length of AB = 8 and Length of A'B' = 4.
Hence A'B'C' is obtained by dilating ABC by a scale factor of 1/2.
Now since moved to III quadrant from I quadrant we find that there is a rotation of triangle ABC about the origin. The degree of rotation is 180 degrees.
Hence A'B'C' is obtained by dilating ABC by a scale factor of 1/2 and then rotating it about the origin by 180 degrees
Answer:
Given: Let x and y be positive integers
Explain why it is incorrect to claim that x/√y is always irrational
Example: Let x = 5, and y = 9.
5/√9=5/3=1.6
Given: 0<A<B
Explain why it is correct to claim that A/B<B/A is true,
It is shown that A/B will always be < 1, and B/A will always be > 1.
Step-by-step explanation:
Rational numbers are numbers that can be written as a fraction of integers. To explain why this statement is incorrect, consider using a perfect square. A perfect square is a number that can be expressed as the product of two equal integers (9, 16, 25…), where y is the perfect square.
