Answer:
126 people
Step-by-step explanation:
Given that, ratio of people who preferred tea to those who preferred coffee = 9:5
Let number of people who preferred coffee = x
Number of people who preferred tea = x + 36
Total number of people in survey = x + (x+36)
Ratio of people who preferred tea to those who preferred coffee = (x + 36)/x = 9/5
Cross multiply to solve for x
5(x + 36) = x(9)
5x + 180 = 9x
Subtract 5x from both sides
180 = 9x - 5x
180 = 4x
Divide both sides by 4
180/4 = x
45 = x
x = 45
<em>Number of people who preferred coffee = x = 45</em>
<em>Number of people who preferred tea = x + 36 = 45 + 36 = 81</em>
<em>Total number of people in the survey = x + (x + 36) = 45 + 81 = 126 people</em>
Answer:
<em><u>135</u></em> cubes would fill the prism
Step-by-step explanation:
volume of one small cube = (1/3)^3
= 0.037 cubic units
Number of cubes that would fill the prism =
5 cubic units / 0.037 cubic units
= 135 cubes
Answer:
A. to make inferences about a sampling technique
Step-by-step explanation:
5/8 - 3/10
Find the common denominator:
Multiples of 8: 8, 16, 24, 32, 40 (8 x 5 = 40)
Multiples of 10: 10, 20, 30, 40 (10 x 4 = 40)
5/8 = 5*5 / 8*5 = 25/40
3/10 = 3*4 / 10 *4 = 12/40
Now you have 25/40 - 12/40
25 -12 = 13
Answer = 13/40
The answer is A.
