Answer:

median=81

mode=73

range=24

Step-by-step explanation:

median: Middle number from lowest to highest crossing one-off from either side.

(73,73,79,81,88,97)

mode:most popular number.

range: highest number minus lowest number.

If Adam and Eve were white then how are black people made, from brown cows? Not trying to be racist UwU

Free_Kalibri [48]

Answer:

If you want me to be honest with you, I will be. The reason black people got their skin color is really because someone was born with a lot of melanin, and what caused that was basically the region and climate the people are living in. People in Africa are most likely to be darker than those who live in Northern Europe.

Three people pull simultaneously on a stubborn donkey. Jack pulls directly ahead of the donkey with a force of 90.5 N , Jill pul

Radda [10]

Answer:

Fn= 174.9 N : Magnitude of the net force the people exert on the donkey.

Step-by-step explanation:

We find the components of the forces in x-y-z

Force of Jack in z =F₁z=90.5 N in direction (+z)

Force of Jill in x = F₂x= -82.3*cos45°= - 58.19 N (-x)

Force of Jill in y =F₂y=-82.3*sin45°= + 58.19 N (+y)

Force of Jane in x =F₃x=125*cos45°= + 88.4 N (+x)

Force of Jane in y =F₃y=125*sin45°= + 88.4 N (+y)

Calculating of the components of the net force the people exert on the donkey.

Fnx= F₂x+F₃x=( - 58.19+ 88.4 )N=30.2N (+x)

Fny= F₂y+F₃y=( 58.19+88.4 ) = 146.59 N (+y)

Fnz =F₁z=90.5 N (+z)

Calculating of the magnitude of the net force the people exert on the donkey.

$F_{n} =\sqrt{(F_{nx})^{2}+(F_{ny}) ^{2} +(F_{nz}) ^{2} }$

$F_{n} =\sqrt{(30.2)^{2}+( 146.59) ^{2} +(90.5) ^{2} }$

$F_{n} = 174.9 N$

What does (f(x)) mean in math for a input and output graph?

shtirl [24]

In maths, f (x) means as a special relationship where every single input has one output.

<u>Step-by-step explanation:</u>

In mathematics, a function is any expression that gives exactly one answer for each particular number. Input is the number provided in the expression, and output is the number obtained from the search or calculation.

In an ordered pair, input’s first number corresponds to the horizontal axis, and output’s second number in the vertical axis. These ordered pairs can then be plotted. Some data on the costs associated with this are called relationships. For example,

$f(x)=x^{2}$
