What is the distance between the two end points (5,6) (-4,-7) round to the nearth two decimal places

Mathematics

The formula of a distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

We have:

(5,\ 6)\to x_1=5,\ y_1=6\\(-4,\ -7)\to x_2=-4,\ y_2=-7

substitute:

d=\sqrt{(-4-5)^2+(-7-6)^2}=\sqrt{(-9)^2+(-13)^2}=\sqrt{81+169}=\sqrt{250}\\\\=\sqrt{25\cdot10}=\sqrt{25}\cdot\sqrt{10}=5\sqrt{10}

Students in a random sample of 57 students measured their handspan. The dot plots display the results for the males and females.
Nat2105 [25]

Answer:

There is a difference in mean hand span between male and female if you notice the difference between their averages.    2cm  is quite significant

female mean = 19.6 cm  and male mean = 21.6 cm

Step-by-step explanation:

a.)  There is a significant difference.

take  P( Z  < ( 19.6 - 21.6) / 1)  = P(Z < -2) = 2% probability of assuming that male and female means are the same.  too low to think like that.

b.) Differ by 2cm.  MAD=  Mean Absolute Deviation , MAD within their own data set  seem similar

C.)  The variability in hand spans among male and female are very similar, since they both have the same MAD = 1.0

I can't figure out the x-intercepts. Help. NO LINKS
zavuch27 [327]

Answer:

(-3,0)

Step-by-step explanation:

To find the x-intercept set y to 0,

x^2 + 6x + 9 = 0     Now you have a quadratic equation, so you can solve it

(x + 3)(x + 3 ) = 0

x + 3 = 0

x = -3
