Step-by-step explanation:
<u>Given:</u>
<u>Find z-score:</u>
- z = (x - μ)/σ
- z = (104 - 80)/12 = 2
Percent value corresponding to 2 as per z-table is 0.9772. This is corresponding to 97.72%.
<u>Percentage of students earned more than $104:</u>
Answer:
There is some mistake in the question, because the solutions are x = -1.445 and x = -34.555
Step-by-step explanation:
Given the functions:
f(x) = x² + 4x + 10
g(x) = -32x - 40
we want to find the points at which f(x) = g(x).
x² + 4x + 10 = -32x - 40
x² + 4x + 10 + 32x + 40 = 0
x² + 36x + 50 = 0
Using quadratic formula:
Answer:
C. 43.6
Step-by-step explanation:
you need to take the area of each shape
lets do the skinny triangles first on the top and bottom of this shape.
so to find the formula of triangle we need to do 0.5 * 1.26 * 5.3
because the formula of a triangle is half the base times height.
so we get 0.5 * 1.26 * 5.3 = 3.339
multiply it by two and we get 6.678
now lets find the area of the huge rectangle on the back/behind of the shape
3.3*5.3 = 17.49
now lets find the area of the two smaller rectangles
3.3 * 3.6 = 11.88
2.3 * 3.3 = 7.59
now lets add
6.678 + 17.49 + 11.88 + 7.59 = 43.638
round it to 43.6
Hi,
Your equation is y=-3/8x+3 because if you do rise over run you get a slope of -3/8 and the y intercept is 3.
Hope this helped!
