Find the x-intercept and the y-intercept of the line below. Click on "None" if applicable.
Answer:
a) None
b) (0, -2)
Step-by-step explanation:
The x-intercept is the point at which the line cuts through the x-axis, while the y-intercept in the point at which the line cuts through the y-axis.
a) The line does not cut through the x-axis, thus it has no x-intercept.
b) The line cuts through the y-axis at y= -2, making its y-intercept (0, -2).
In a recent poll among 500 students, it was found that 60% of women and 68% of men eat meals on campus at least 3 times a week. What type of statistical test would you use to see whether men and women differ in the extent to which they eat meals on campus at least three times a week
The statistical test would be a Z-test for the difference between the proportions.
What is Z-test?The Z test is a parametric procedure that is used on data that is dispersed in a normal fashion. For testing hypotheses, the z test can be used on one sample, two samples, or proportions. When the population variance is known, it analyzes if the means of two big groups are dissimilar.
We have:
In a recent poll among 500 students, it was found that 60% of women and 68% of men eat meals on campus at least 3 times a week.
From the above data and the definition of the Z-test, the statistical test would be a Z-test for the difference between the proportions.
Thus, the statistical test would be a Z-test for the difference between the proportions.

Answer:
75582
Step-by-step explanation:
The order of the correct problems does not matter, so the number of ways 8 of 19 problems can be correct is the number of combinations of 19 things taken 8 at a time:
C(n, k) = n!/(k!(n-k)!)
C(19, 8) = 19!/(8!(11!)) = 75582

k(x)=x^(2)+3x+8
find k(-1)
find k(0)
find k(5)
Answer:
6, 8, 48
Step-by-step explanation:
substitute x = - 1, 0, 5 into k(x)
k(- 1) = (- 1)² + 3(- 1) + 8 = 1 - 3 + 8 = 6
k(0) = 0² + 3(0) + 8 = 0 + 0 + 8 = 8
k(5) = 5² + 3(5) + 8 = 25 + 15 + 8 = 48

Which equation could be solved using this application of the quadratic formula? a. -2x2 − 8 = 10x − 3 b. 3x2 − 8x − 10 = 4 c. 3x2 8x − 10 = -8 d. -2x2 8x − 3 = 4
The equation that can be solved when the given quadratic formula is used is c. 3x² + 8x − 10 = -8.
How can we use quadratic equations?The given quadratic equation is:
x = (-8 ± √(8² - 4(3)(-2))) / 2 (3)
Rewriting the quadratic equation in option C gives:
3x² + 8x − 2 = 0
Seeing as a quadratic equation takes the form:
x = (-b ± √(b² - 4(a)(c))) / 2 (a)
The formula becomes:
x = (-8 ± √(8² - 4(3)(-2))) / 2 (3) which is the given quadratic formula.
In conclusion, option C is correct.

In Lin's drawing, the scale is 5 inches = 8 feet, and the back wall of the lab measures
15 inches. Five computer workstations will be equally spaced along the entire
length of that wall. Each workstation measures 4 feet by 4 feet. How far apart are
the workstations in Lin's drawing? Explain.
Answer:
1 ft
Step-by-step explanation:
scale: 5 in. = 8 ft
Back wall scale measurement: 15 in.
Back wall real measurement: 15 in. × 8 ft / 5 in. = 24 ft
Each workstation measures 4 ft.
5 workstations measure 5 × 4 ft = 20 ft
24 ft - 20 ft = 4 ft
When you place 5 workstations, the outer two will be at the ends of the 24-ft wall. There will be 4 spaces between the workstations.
4 ft / 4 = 1 ft
Answer: 1 ft

Answer:
see explanation
Step-by-step explanation:
the standard form of a quadratic expression is ax² + bx + c ( a ≠ 0 )
(1)
(2x + 5)(x + 1)
each term in the second factor is multiplied by each term in the first factor, that is
2x(x + 1) + 5(x + 1) ← distribute parenthesis
= 2x² + 2x + 5x + 5 ← collect like terms
= 2x² + 7x + 5 ← in standard form (a = 2, b = 7, c = 5 )
(2)
(x - 2)(x + 2)
= x(x + 2) - 2(x + 2) ← distribute parenthesis
= x² + 2x - 2x - 4 ← collect like terms
= x² - 4 ← in standard form (a = 1, b = 0, c = - 4 )

x = -1
Step-by-step explanation:
[tex] \sf\frac{x}{x - 2} + \frac{x - 1}{x + 1} = - 1[/tex]
Taking LCM
[tex] \sf \hookrightarrow \frac{x(x + 1) + (x - 1)(x - 2)}{(x - 2)(x + 1)} = - 1 \\ \\ \sf \hookrightarrow \frac{ {x}^{2} + x + {x}^{2} - 3x + 2 }{ {x}^{2} - x - 2} = - 1 \\ \\ \sf \hookrightarrow \frac{2 {x}^{2} - 2x + 2 }{ {x}^{2} - x - 2 } = - 1[/tex]
Cross multiplying
[tex] \sf \hookrightarrow 2 {x}^{2} - 2x + 2 = - 1( {x}^{2} - x -2) \\ \\ \sf \hookrightarrow 2 {x}^{2} - 2x + \cancel2 = - {x}^{2} + x + \cancel2 \\ \\ \sf \hookrightarrow 3 {x}^{2} - 3x = 0[/tex]
Taking 3 common
[tex] \sf \hookrightarrow {x}^{2} - x = 0 \\ \\ \sf \hookrightarrow x(x - 1) = 0 \\ \\ \sf \hookrightarrow x - 1 = 0 \\ \\ \\ \green{\boxed{ \hookrightarrow x = 1}}[/tex]
VerifyingTaking x as 1
[tex] \sf \implies\frac{x}{x - 2} + \frac{x - 1}{x + 1} = - 1 \\ \\ \sf \implies \frac{1}{1 - 2} + \frac{1 - 1}{1 + 1} = - 1 \\ \\ \sf \implies - 1 + 0 = - 1 \\ \\ \sf \implies - 1 = - 1[/tex]
