A rational number is one that u can turn into a fraction.
Anytime u have a whole number and u want to turn it into a rational number, put it over 1.
7 to a rational number would be 7/1
The greatest number of orange beads and blue beads bracelets will be 6.
Step-by-step explanation:
Here you find the largest factor shared by the two numbers : 72 and 78. This is the same as finding the G.C.F of a set of numbers.In finding the greatest common factor, list the prime factor of each number and multiply the factors that both numbers have in common. In this case, it will be:
72 78 --------------divided by 2
2 36 39 --------------divided by 3
3 12 13 --------------no common divider
The greatest number of orange beads and blue beads bracelets will be 2*3=6

Answer: Simple random sampling.
Step-by-step explanation:
A simple random sample is basically a subset (with size n) from the entire population, where the chance of getting selected for each element is equal.
Given :A research company believes teens today are getting less than the recommended hours of sleep. The company takes a list of 2000 teen volunteers and assigns each volunteer a number. A
A random number generator is used to select 350 individuals to take part in a sleep survey.
It is a simple random sampling because the researcher selected participants randomly such that the chance to get selected for each of them remains same.
For this case we have the following functions:
f (x) = 2x2 - 10
g (x) = x + 9
Evaluating both functions for x = 2 we have:
f (2) = 2 (2) ^ 2 - 10 = 8 - 10 = -2
g (2) = (2) + 9 = 2 + 9 = 11
Then, multiplying both functions we have:
(f ⋅ g) (2) = (-2) (11)
(f ⋅ g) (2) = -22
Answer:
the correct answer below is:
-22
The answer is D
Explanation:
The -2 on the X is reversed so it becomes +2 on the x-axis
The +2 at the end of the equation makes the graph go up 2
