Answer:
880
Step-by-step explanation:
This problem a bit annoying, but let's classify the numbers and see where we can get from there:
Total = 10,000
Young = 3,000
Old = 7,000 (not young defined as 10,000 - 3,000)
Male = 4,600
Female = 5,400
Married = 7,000
Single = 3,000
Young Males = 1,320
Young Females = 3,000 (young) - 1,320 = 1,680
Married Males = 3,010
Married Females = 7,000 - 3,010 = 2,990
Young Married = 1,400
Young Married Males = 600
Young Married Females = 1,400 - 600 = 800
Young Female Single = ?
Young Female = 1,680 from above. But not all of them are single.
Young Married Females = 800 from above
Young Female Single = Young Female - Young Married Females = 1,680 - 800 = 880
Answer:
C: Xint = 2, Yint. = -7
Step-by-step explanation:
Given the equation, 2x - 7y = -14:
The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates (0, b). It is also the value of y when x = 0. To solve for the y-intercept, set x = 0:
2x - 7y = -14
2(0) - 7y = -14
0 - 7y = -14
-7y = -14
Divide both sides by -7 to solve for y:
-7y/-7 = -14/-7
y = 2
Therefore, the y-intercept = 2.
Next, the x-intercept is the point on the graph where it crosses the x-axis, and has coordinates, (a, 0). To find the x-intercept, set y = 0 and substitute into the given equation:
2x - 7y = -14
2x - 7(0) = -14
2x - 0 = -14
2x = -14
Divide both sides by 2 to solve for x:
2x/2 = -14/2
x = -7
x-intercept = -7.
Therefore, the correct answer is C: Xint = 2, Yint. = -7
