Answer:
Area of the actual room = 288 m²
Step-by-step explanation:
Given:
Scale factor = 2cm to 4 m
Dimension of rectangle ball room = 6 cm and 12 cm
Find:
Area of the actual room
Computation:
Actual dimension of rectangle ball room;
⇒ [6/2]4 = 12 m
⇒ [12/2]4 = 24 m
Area of rectangle = Length x Width
⇒ Area of the actual room = Actual length x Actual width
⇒ Area of the actual room = 12 x 24
Area of the actual room = 288 m²
There is a 2.3% chance that 30% or more of a sample of 300 American adults say they are not at all confident that the records of their activity maintained by credit card companies will remain private and secure if 25% of Americans are not at all confident this year. Answer:
Step-by-step explanation:
The null hypothesis is “the percentage of American adults say they are not at all confident that the records of their activity maintained by credit card companies will remain private and secure is 25%. If this is true, there is a 2.3% chance that a sample of 300 American adults will have 30% or more who say they are not at all confident.

Answer:
1 quart of oil is $2.
Step-by-step explanation:
Represent the problem with equations.
let x be a quart of oil and g be a gallon of gasoline
(1) 24.5 = 10g + x
(2) 22 = 8g + 2x
We need to solve this system of equations to get x.
I can solve by elimination by making both equations have 2x.
Multiply equation (1) by 2. Equation (2) remains the same.
(1) --> 49 = 20g + 2x
(2) 22 = 8g + 2x
Subtract (2) from (1) to get:
27 = 12g <= isolate g
g = 27/12
g = 9/4
Substitute g = 9/4 in (2)
22 = 8g + 2x
22 = 8(9/4) + 2x
Now simplify and isolate x.
22 = 18 + 2x
2x = 4
x = 2
x represents one quart of oil.
Therefore, one quart of oil is $2.
