PLEASE HELP The following table gives the heights and weights of 10 friends

Mathematics

ohaa [14]3 years ago

Graph is attached.

Based on the graph (with height on the independent axis and weight on the dependent), there is a negative correlation between height and weight; as the height increases, the weight decreases.

If we were to graph this with weight on the independent axis and height on the dependent, there would still be a negative correlation.

Linda is 12 years younger than her sister Laura. Together their total age is 18. How old is Linda? How old is Laura?
geniusboy [140]

Answer:

Linda: 3 ; Laura: 15

Step-by-step explanation:

Note that Linda + Laura's age is 18, and that Linda is 12 years younger than her sister.

Let "Linda" = x , "Laura" = y:

x + y = 18

x = y - 12

First, plug in y - 12 for x in the first equation:

(y - 12) + y = 18

Simplify.

2y - 12 = 18

Isolate the variable (y). Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First add, then divide.

2y - 12 (+12) = 18 (+12)

2y = 18 + 12

2y = 30

(2y)/2 = (30)/2

y = 30/2

y = 15

Next, plug in 15 for y in the second equation (the other equation would work too).

x = y - 12

x = (15) - 12

x = 3

Linda's age is 3, Laura's age is 15.

Can someone please help me please
qwelly [4]

Answer:

1) \dfrac{12+\sqrt{-16}}{4}=\dfrac{12+\sqrt{16i^{2}}}{4}\\\\\\=\dfrac{12+4i}{4}=\dfrac{12}{4}+\dfrac{4i}{4}\\\\\\= 3 + i

Real part = 3  & imaginary part = 1

2) 4 + 7i - 8 = 4 -8 + 7i

                   = -4 + 7i

Real part = -4 & imaginary part = 7

3)\dfrac{\sqrt{9}+\sqrt{-4}}{5}=\dfrac{3+\sqrt{4i^{2}}}{5}\\\\\\=\dfrac{3}{5}+\dfrac{2i}{5}\\\\\\Real \ part = \dfrac{3}{5} \ & \ imaginary \ part = \dfrac{2}{5}

4) -2-\sqrt{-25}=-2-\sqrt{25i^{2}}=-2-5i

Real part = -2  & imaginary part = -5

5)\dfrac{15-13i}{3}=\dfrac{15}{3}-\dfrac{13i}{3}\\\\\\Real \ part = \dfrac{15}{3} \ & \ imaginary \ part = \dfrac{-13}{3}

b) 1) 6 + 4i

2) -12+ 5i

3) 5-14i
