Answer: 2√10 - √30
explanation:
ok so they’re asking for the difference between the lengths of the sides of each cube. they have different SA’s (surface areas). all you gotta do is plug in the SA in the given equation to find the length of the side and THEN you subtract the answers and thats how you find the difference between the sides.
given:
s = √(SA/6)
SA1 = 240 m^2
SA2 = 180 m^2
S1 = √(240/6) = 2√10 or 6.32
S2 = √(180/6) = √30 or 5.47
s1 -s2 = 2√10 - √30
Answer:
x > or equal to 9.7
Step-by-step explanation:
Don't let the inequality intimidate you. Treat the > or equal sign like it is an equal sign.
Any thing you do on the right you must do on the left.
move 3 to other side
combine like terms
15x > or equal to 145.5
Divide both sides by 15
x > or equal to 9.7
Answer:
13.8%
Step-by-step explanation:
P = nCr pʳ qⁿ⁻ʳ
P = ₉C₅ (0.37)⁵ (1−0.37)⁹⁻⁵
P ≈ 0.138
Answer:
(B) A selected group of participants that is representative of a larger population
Step-by-step explanation:
A sample statistic is a piece of information that you get from a fraction of the population. This information is representative of a larger population.
For example, someone wants to conduct a survey about the most popular NFL team in Syracuse, NY, if it is the Buffalo Bills or the New York Giants. This person is not going to ask each person for whom they cheer. They are going to collect data from a fraction of the population and this data will be expanded to include the entire population.
So, the correct answer is:
(B) A selected group of participants that is representative of a larger population
