Answer:
40%
Step-by-step explanation:
Prime numbers are whole numbers greater than 1 that only have 2 factors, for example, 2, 3, 5, 7, 11 are all prime numbers
In this data set 2, 3, and 5 are all prime numbers
3 out 5 numbers are prime
so the fraction is
after you have found the fraction, you can divide it to find the percentage
In this case, when you divide the fraction you get 0.6
to make this a percentage you move the decimal place two spaces to the right. so 60%
60% are the values that are prime so you do this equation
100%-60%=40%

Answer:
segment AB over segment A double prime B double prime = the square root of 13 over 2 times the square root of 13
Step-by-step explanation:
Triangle ABC has vertices at points A(-3,3), B(1,-3) and C(-3,-3).
1. Reflection over x = 1 maps vertices A, B and C as follows
- A(-3,3)→A'(5,3);
- B(1,-3)→B'(1,3);
- C(-3,-3)→C'(5,-3).
2. Dilation by a scale factor of 2 from the origin has the rule
(x,y)→(2x,2y)
So,
- A'(5,3)→A''(10,6);
- B'(1,3)→B''(2,6);
- C'(5,-3)→C''(10,-6)
See attached diagram for details
