Hello,

Assume Ax+By+Cz+D=0 the plane 's equation.

p=(0,0,0)==>A*0+B*0+C*0+D=0==>D=0

q=(0,1,0)==>A*0+B*1+C*0+0=0==>B=0

r=(1,2,3)==>A*1+0*2+C*3+0=0==>A=-3C
Let C=1==>A=-3

An equation of the plane is -3x+z=0

Alla [95]

(b) The monthly savings of Juan is $200.

(a) The monthly saving of Juan is $900.

As we know that

Savings = Income - expenses

So based on the above formula, the monthly savings in each case is as follows:

(b)

Monthly saving is

= $3,600 - $3,400

= $200

(a)

Monthly saving is

= $3,600 - $2,500

= $900

(c)

Monthly saving is

= $3,600 - $0

= $3,600

Here we assume the x be zero.

Therefore we can conclude that

(b) The monthly savings of Juan is $200.

(a) The monthly saving of Juan is $900.

AfilCa [17]

Hello! I can help you!
So, when you look at the problem, 75h can not be it. The answer is definitely 0.09, because that mean stuff you'd have to pay 9% tax and that usually the amount of tax you may pay on some items. The part of the expression that represents tax is 0.09.

James flips a fair numbered cube with faces numbered 1-6 and flips a quarter what is the probability that in one turn James coul

Whitepunk [10]

Answer:

Therefore the probability that in one turn James could roll an odd number and fip a heads on the quarter is = $\frac{1}{2}$ × $\frac{1}{2}$ = $\frac{1}{4}$ .

Step-by-step explanation:

i) There are three odd numbered faces on the cube, that is the faces having 1, 3, and 5.

Therefore the probability of rolling an odd numbered face is = $\frac{1}{6} + \frac{1}{6} + \frac{1}{6} = \frac{1}{2}$ since the probability of rolling 1 = probability of rolling 3 = probability of rolling 5 = $\frac{1}{6}$

ii) The probability of flipping a head on the quarter = probability of flipping a tail on the quarter = $\frac{1}{2}$

iii) Therefore the probability that in one turn James could roll an odd number and fip a heads on the quarter is = $\frac{1}{2}$ × $\frac{1}{2}$ = $\frac{1}{4}$
