Digiron [165]
<span>The list of scores will be: 30 60 63 65 65 67. To get the median, you have to arrange the scores from lowest to highest. The middle number is the median. In this, case there are two numbers in the middle so you have to add the two and then divide by two.</span> <span>Therefore, 63 + 65 = 128 / 2 = 64.</span>

Can the polynomial equation have exactly 1 real solution, including any repeated solutions? (Use the Fundamental Theorem of Alge
Kryger [21]

yes, there are infinitety many polynomial that have exactly one real root just like your example, to determine the real root first let the real root is a, and the complex roots are b±ic the polynomial satisfy

-9x³ + 19x² + 17 = -(x - a)(x - b - ic)(x - b + ic)

9x³ - 19x² - 17 = (x - a)(x - b - ic)(x - b + ic)

What is the inverse of the function h(x)=\dfrac{5}{2}x+4h(x)= 2 5 ​ x+4h, left parenthesis, x, right parenthesis, equals, start
Phantasy [73]

Answer:

The inverse of the function h(x) is h^{-1}(x)=\frac{2}{5}x-\frac{8}{5}.

Step-by-step explanation:

The given function is

h(x)=\dfrac{5}{2}x+4

Replace h(x) by y.

y=\dfrac{5}{2}x+4

Interchange x and y.

x=\dfrac{5}{2}y+4

Subtract 4 from both sides to isolate variable y,

x-4=\dfrac{5}{2}y

Multiply both sides by 2.

2x-8=5y

Divide both sides by 5.

\frac{2}{5}x-\frac{8}{5}=y

Replace y by h⁻¹(x).

h^{-1}(x)=\frac{2}{5}x-\frac{8}{5}

Therefore the inverse of the function h(x) is h^{-1}(x)=\frac{2}{5}x-\frac{8}{5}.

Mkey [24]
From x equals five to nine, the y value changes as follows
+10,+2,+1,+3
Assuming that "average" implies the mean, the sum of all four values is 15. Then divide 15 by the four values added = 15/4 = 3 3/4 or 3.75
