Answer:

9

Step-by-step explanation:

<em>Degrees of freedom</em> is the number of values in the final calculation of a statistic that are free to vary. Degrees of freedom are related to sample size and calculated by n-1 where n is the <em>sample size</em>.

The Supervisor selects 10 teddy bears as sample from 5000 teddy bears produced daily.  Therefore in this situation, there are 10-1=9 degrees of freedom

The ball's height (in meters above the ground), xxx seconds after Antoine threw it, is modeled by: h(x)=-2x^2+4x+16 How many sec
zlopas [31]

Answer:

Step-by-step explanation:

If we are given the quadratic model, we know that the height of anything on the ground is 0 meters, so that model becomes

0=-2t^2+4t+16 I changed your x's to t's since t is for time.

Now we need to factor that quadratic and solve for time:

0=-2(t^2-2t-8)

Since -2 definitely does not equal 0, then

t^2-2t-8=0

Factor that and find t values of 4 and -2.  Again, we know that time will never be negative, so

t = 4 seconds.

What is the distance between the points (-4,2) and (3,-5)
34kurt

Answer:

7√2 units

Step-by-step explanation:

The distance between two points having coordinates (x1, y1) and (x2, y2) is given by,

\sqrt{ {(x2 - x1)}^{2}  +  {(y2 - y1)}^{2} }

Here, x1=-4 and y1=2

x2=3 and y2=-5

\sqrt{ {(3  - ( -  4))}^{2}  +  {( - 5 - 2)}^{2} }

\sqrt{ {(3 + 4)}^{2}  +  {( - 7)}^{2} }

\sqrt{ {(7)}^{2}  +  {( - 7)}^{2} }

\sqrt{49 + 49}  = 7 \sqrt{2}

What percent of 150 is 162
Novay_Z [31]
To find a percentage of a number, you divide by that number.
So to find what percent of 150 162 is, you divide 162 by 150
162 ÷ 150 = 1.08
Now, to find the percentage, we take the decimal and move the point two places to the right.
1.08 = 108%
162 is 108% of 150.
