Prove that using: X ∩ (Y ∪ Z ) =(X∩Y) ∪ (Y ∩ Z )
sertanlavr [38]

There should be a typo in the question: the correct formula would be

X\cap(Y\cup Z)=(X\cap Y)\cup (X\cap Z)

Let's compute X\cap (Y\cup Z) first. We have

(Y\cup Z)=\{1, 4, 5, 6, 7, 8, 9\}

If we intersect this set with X, we have

X\cap (Y\cup Z) = \{5, 8, 9\}

So, that would be the left hand side. For the right hand side, we have

X\cap Y = \{8\},\quad X\cap Z = \{5,9\}

And their union is again \{5,8,9\}

You want to buy a car, and a local bank will lend you $30,000. The loan would be fully amortized over 6 years (72 months), and t
Georgia [21]

Answer:

<h2>- 56,667cents</h2><h2>- 6.17%</h2>

Step-by-step explanation:

Before we can determine the monthly loan paymnet, we must first calculate the total amount paid at the end of 6years.

Amount = Principal + Interest

Given Principal = $30,000

Interest = Principal * rate * time/100

Interest = $30,000*6*6/100

Interest =  $10,800

Amount =  $30,000+ $10,800

Amount =  $40,800

If amount paid after 6years is $40,800, my monthly loan payment = $40,800/72 ≈ $566.67 to nearest dollar.

since $1 - 100cents

$566.67 = 100 * 566.67

$567 = 56,667cents

Monthly loan payment to nearest cent will be  56,667cents

EFF = (1 + r /n)^n - 1

r is the rate and n is the number of period per year which is 12months

%EFF = EAR = (1 + 0.06 /12)^ 12 - 1

%EFF = 1.005^12

%EFF = 1.061678 - 1

%EFF = 0.061678

%EFF = 6.17% to 2dp

I will cashapp you not playin but don’t give me the wrong Answer and explain
velikii [3]

Answer:

It would be option two: Bill's Electric Company charges 6 dollars per hour plus a flat rate of 15 dollars for a service call. If Monica has at least 100 dollars to spend, how many hours can the service man work?

Step-by-step explanation:

6 dollars an hour means it would be 6x.

A flat rate of 15 means there would be just 15 as a number, no x's.

And the sign is less than or equal to, so she has over a hundred dollars to spend.
