Answer:
the standard form of this equation will be 3z^4 + 2z^3 - z^2 + 5z
Step-by-step explanation:
as much as I would like to, I'm really not that good at explaining things
Answer:
375
Step-by-step explanation:
500-125(25% of 500)=375
Step-by-step explanation:
So i will try to explain it:
Scientists in the past invented this formula and theory of sines:

So the only thing is to put the given numbers into this formula :)
The task that i've just done is like this:

a is the numerator,that is delighted in the triangle,well its transparent.
What about denominator?
Here is the tip:
opposite to A- side angle-a has to be put into sin(a)
sin- how to calculate?
Easy just take the trigonometric functions formula or calculate in scientific calculator that's it.

one of this numbers might be unknown in that case solve by proportion(equation).
Carefully contemplate my answer in the media.
I hope you understood.
Good luck!

Answer:
a) 0.69
The probability that a randomly selected 10-year old child will be more than 51.75 inches tall
P(X>51.75 ) = 0.6915
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
<em>Given mean of the Population = 54.6 inches</em>
<em>Given standard deviation of the Population = 5.7 inches</em>
<em>Let 'X' be the random variable of normal distribution</em>
Let 'X' = 51.75 inches

<u><em>Step(ii):</em></u>-
<em>The probability that a randomly selected 10-year old child will be more than 51.75 inches tall</em>
<em>P(X>51.75 ) = P(Z>-0.5)</em>
= 1 - P( Z < -0.5)
= 1 - (0.5 - A(-0.5))
= 1 -0.5 + A(-0.5)
= 0.5 + A(0.5) (∵A(-0.5)= A(0.5)
= 0.5 +0.1915
= 0.6915
<u><em>Conclusion</em></u>:-
<em>The probability that a randomly selected 10-year old child will be more than 51.75 inches tall</em>
<em>P(X>51.75 ) = 0.6915</em>
