Say the number of hours that she works is h.
<span>h<_15             (h is greater than or equal to 15)</span>
In one week, if she wants to earn the most, she has to work 15 hours. 
15*7= $105
Hope this helps.

Circle F is congruent to circle J, and ∠EFD ≅ ∠GJH. Circles F and J are congruent. Line segments F E and F D are radii. A line c
Rzqust [24]

Answer:

mGH=80^\circ

Step-by-step explanation:

Circle F and J are congruent.

\angle DFE \cong \angle GJH

Given that: m∠DFE = 80°

DFE is the central angle of the circle F.

The measure of arc GH is equal to the central angle of Circle J.

Since both circles are congruent

mGH=\angle DFE = 80^\circ

The measure of arc GH is 80 degrees.

It is known that 25% of inhabitants of a community favour a political party A.
Keith_Richards [23]

Answer:

i) P(X=2)=(20C2)(0.25)^2 (1-0.25)^{20-2}=0.0669

ii) P(X=0)=(20C0)(0.25)^0 (1-0.25)^{20-0}=0.00317

P(X=1)=(20C1)(0.25)^1 (1-0.25)^{20-1}=0.0211

P(X=2)=(20C2)(0.25)^2 (1-0.25)^{20-2}=0.0669

And replacing we got:

P(X \geq 3) = 1- [0.00317+0.0211+0.0669]= 0.90883

iii) P(X

Step-by-step explanation:

Let X the random variable of interest "number of inhabitants of a community favour a political party', on this case we now that:

X \sim Binom(n=20, p=0.25)

The probability mass function for the Binomial distribution is given as:

P(X)=(nCx)(p)^x (1-p)^{n-x}

Where (nCx) means combinatory and it's given by this formula:

nCx=\frac{n!}{(n-x)! x!}

Part i

We want this probability:

P(X=2)=(20C2)(0.25)^2 (1-0.25)^{20-2}=0.0669

Part ii

We want this probability:

P(X\geq 3)

And we can use the complement rule and we have:

P(X\geq 3) = 1-P(X

And if we find the individual probabilites we got:

P(X=0)=(20C0)(0.25)^0 (1-0.25)^{20-0}=0.00317

P(X=1)=(20C1)(0.25)^1 (1-0.25)^{20-1}=0.0211

P(X=2)=(20C2)(0.25)^2 (1-0.25)^{20-2}=0.0669

And replacing we got:

P(X \geq 3) = 1- [0.00317+0.0211+0.0669]= 0.90883

Part iii

We want this probability:

P(X

And replacing we got:

P(X
