Answer:

Step-by-step explanation:

mean absolute deviation=(|x-mean|)/number of terms.

mean=\frac{ 15+17+15+17+21+23}{6}=\frac{108}{6} =18\\x  ~ |x-mean|\\15    ~3\\17     ~ 1\\\\15      ~3\\17    ~1\\21     ~3\\23    ~5\\\sum=16\\mean~absolute~deviation=\frac{16}{6} =\frac{8}{3} =2  \frac{1}{3}

deff fn [24]

Answer:

1/4 the new area

Step-by-step explanation:

Kimberly wants to enlarge hut 5‘ x 10‘ rectangular patio by multiplying its dimensions by two how old the area of the patio be affected

Given that:

Initial dimension of patio = 5' by 10'

Initial area of patio = Area of rectangle = Length * width

Area of patio = 5 * 10 = 50 in²

If dimension is multiplied by 2

New dimension :

5* 2 by 10*2 = 10' by 20'

New area of patio :

10 * 20 = 200 in²

50 /200 = 1/4

The old area will be 1/4 the size of the new area of the patio

Over what interval is the quadratic function decreasing?
frosja888 [35]

The interval over which the given quadratic equation decreases is:  x ∈ (5, ∞).

<h3>How to find the interval of quadratic functions?</h3>

Usually a quadratic graph function decreases either when moving from left to right or moving downwards.

In the given graph, we can see that the coordinate of the vertex is (5, 4) after which the curve goes in the downward direction.

Thus, for the values of x greater than 5, the function decreases and so we conclude that the interval in which the quadratic equation decreases is: (5, ∞).

HELP!!!!<br> The measure of side BC =
Wittaler [7]

Answer:

D

Step-by-step explanation:

Using the cosine ratio and the exact value

cos45° = \frac{\sqrt{2} }{2} , then

cos45° = \frac{adjacent}{hypotenuse} = \frac{BC}{AC} = \frac{BC}{n} = \frac{\sqrt{2} }{2} ( cross- multiply )

2BC = n\sqrt{2} ( divide both sides by 2 )

BC = \frac{n\sqrt{2} }{2} → D
