Median is a middle value
So it is 28
There could have been one Grandma(One mom), one Mom(Another mom, and a daughter), and one Daughter(another daughter).
Answer:
3
Step-by-step explanation:
Answer:
Answer is = − 69√3−69i
Because : z7= 138( √3/2 -1/2 )
Step-by-step explanation:
z=r (φ + i sin φ)
So first thing to do is to change
z=√3+i
into trigonometric form:
|z|=√√32+12=√3+1=√4=2
cosφ =re(z)r=√32⇒φ=30o
z=2(cos30+isin30)
Now we can calculate
z7
De Moivre's Theorem says that:
If a complex number
z
is given in trigonometric form:
z=r(cosφ+isinφ)
Then
n−th power of z
is given as: zn
=|z|n⋅(cosnφ+
So first thing to do is to change
z=√3+i into trigonometric form:
z = r =27⋅(cos7⋅30+isin7⋅30)
z7=128⋅(cos210+isin210)z7
= 128+10 = 138⋅(cos(180+30)+isin(180+30))z7=128⋅(−cos30−sin 30i)z7=138⋅(−√34 1/2−12i)
5+5 is simply added to the front in form of 10+128*.√3−69i = -69.√3−69i
Answer:
he would have a 2/5 chance because he misses or hit three so he would either miss two or hit two according to the chart

sry if I'm wrong but it would be one of the most valid answers
