Answer:
C. The percentage of all homeowners that own at least one dog
Step-by-step explanation:
A parameter describes an entire population. Timothy is sampling from the 100 random homeowners to extrapolate their opinions onto the opinions of the entire population of homeowners.
Let,
digital cameras be "x"
video cameras be "y"
Now,
According to the question,
5x + 3y = $3,213..................................................equation (1)
y = 4x..................................................................equation (2)
Taking equation (1)
5x + 3y = $3,213
Substituting the value of "y" from equation (2), we get,
5x + 3(4x) = $3,213
5x + 12x = $3,213
17x = $3,213
x = $3,213 / 17
x = $189
Taking equation (2)
y = 4x
Substituting the value of "x", we get,
y = 4 ($189)
y = $756
Now,
John buys a digital and a video camera. So, it costs him ($189 + $756) = $945
Answer:
it is 20%
Step-by-step explanation:
easy
Answer:
x = 50
Step-by-step explanation:
Since the two angles are supplementary, add them together and set them equal to 180 degrees
2x + 2x - 20 = 180 Combine like terms
4x - 20 = 180
+ 20 + 20 Add 20 to both sides
4x = 200 Divide both sides by 4
x = 50
