Ok. <span>Population = 100,000 *1.045^n (n is number of years since 1999. So, the population in 2005 (where n=6) is 130,226

Help please... I don't understand
olchik [2.2K]
Basically they want you to move the variables around so that it matches the standard form which is Ax+By=C.A,B,and C are just coefficients/constants.
so the original equation is
y=x-4
Minus x from both sides to move x to the left hand side.
-x+y=-4
so thats the final answer

Alecsey [184]

Answer:

first, we put them in order

78,[80],83,(85),86,[87],90

Q1 = 80

Q2 (median) = 85

Q3 = 87

Interquartile range (IQR) = Q3 - Q1 = 87 - 80 = 7 <==

Hope this helps!

A family consisting of three persons—A, B, and C—goes to a medical clinic that always has a doctor at each of stations 1, 2, and
Free_Kalibri [48]

Answer:

Step-by-step explanation:

When A, B,C are equally likely to be assigned to any one of the stations 1,2 or 3

we find that each one assigned to one station has probability 1/3

Also each person is independent of the other.

Probability that

a) All three family members are assigned to the same station

= P(ABC) to same station

= P(ABC) to 1+P(ABC) to 2 +P(ABC) to 3

=3*P(A)P(B)P(C) since independent

=3*(\frac{1}{3} )^3\\=\frac{1}{9}

b) This would be equivalent to 1- all 3 to the same station

= 1-\frac{1}{9} \\=\frac{8}{9}

c) Every member to a different station

A has 3 choices while B has remaining 2 and C has 1

Hence prob = \frac{3*2*1}{3*3*3} =\frac{2}{9}

Sophia’s work factoring a perfect square trinomial is (4x+5)^{2}.

Step-by-step explanation:

We have,

16x^2 – 40x + 25

= (4x)^2 - 2(4x)(5) + 5^{2}

Using the algebraic identity,

(a+b)^{2}=a^{2}+2ab+b^{2}

= (4x)^2 - 2(4x)(5) + 5^{2}

= (4x+5)^{2} ≠ ((x + 5)^2

Thus, Sophia’s work factoring a perfect square trinomial is (4x+5)^{2}.
