What’s the distance between (-2,0),(-3,-1)

Answer:

\sqrt{2}

Step-by-step explanation:

You want to use the distance formula: d = \sqrt{(x2 - x1)^{2} + (y2 - y1)^{2}  }

so, to start, fill in what you know. \sqrt{(-3 - -2)^{2}+ (-1 - 0)^{2}  }

now we are going to simplify what we have. if you have minus a negative number, the negatives cancel out, and sow we actually add -3 and  the --2 turns into 2.  (so -3 + 2)

\sqrt{(-1)^{2}+ (-1)^{2}  }

now we can square these \sqrt{1+1}

and now we have to keep going and we get this: \sqrt{2}

so the distance between the two points is \sqrt{2}!

Carey creates the table below to help him determine 75% of 36. 75% of 36 25% 25% 25% 25% One-fourth One-fourth One-fourth One-fo
alina1380 [7]

Answer:

The correct option is (A).

Step-by-step explanation:

The expression Carey is solving is:

X=75\%\ \text{of}\ 36

Simplify the expression as follows:

X=75\%\ \text{of}\ 36

   =\frac{75}{100}\times 36\\\\=\frac{3}{4}\times 36\\\\=3\times 9\\\\=27

So, in Carey's calculation the third step is incorrect.

Instead of 27 the three-fourth must be multiplied by 36 to get the correct answer.

Thus, the correct option is (A).

Consider the accompanying set of dependent and independent variables. The variable x3 is qualitative with H=​High, M=​Medium, an
Dominik [7]

Answer:

Y = 6.6406 + 0.2068x2 + 0.7995x3 - 3.607x4

Step-by-step explanation:

y 63 53 77 53 38 43 34 20 13

x1 45 42 40 37 27 24 20 14 12

x2 74 62 80 53 42 48 35 16 13

x3 H H L M H M L L M

For regression analysis : all variables must be quantitative ;

X3 variable may be represented as thus;

L = 1 ; M = 2 ; H = 3

Hence ;

X3 = 3 3 1 2 1 2 1 1 2

y= ____ + (____)x2+ (____)x3 + (____)x4

Using the online multiple regression calculator :

Y = 6.6406 + 0.2068x2 + 0.7995x3 - 3.607x4

From the general formular of a linear model:

y = w1x1 + w2x2 +... + wnxn + c = 0

Where c = intercept

w1,.. wn = weight of explanatory variable

Hence, the weights of x2 = 0.2068

Weight of x3 = 0.7995

Weight of x4 = - 3.607

Intercept = 6.6406

What is this equation in function notation?
ANEK [815]
You're not dumb! The best and effective way to solve this problem is to isolate the y variable. Divide the whole thing by 150, and you get y=10-1/2x
And then you just add f(x) instead of y to get f(x)=10-1/2x as your final answer.

PLEASE! I NEED HELP. ITS VERY EMERGENCY
WITCHER [35]
Here it is:

The first set has (0,1) and (0,5), which assigns to the *same* x, more than one value of *y*. That's not a function. It's a curve. Think about a circle, or instance. It's NOT a function, but it's a curve.

The second one has for each *x* a single *y*

BTW, there's no problem if for *different* x there is the same *y*:

y = 5,

all x, have the same y, equal to 5. That's a function, or y = x^2, etc
