Are these calculated correctly?

14. Was the perimeter calculated correctly?

  • Length = 4 yards

  • Breadth = 1 *2/5 yards = 7/5 yards

We know that,

Perimeter of rectangle = 2 ( l + b )

= 2 ( 4 + 7 / 5 )

= 2 ( 20 + 7 / 5 )

= 2 × 27/5

= 54 / 5

= 1 * 4/5

No ...

When the side of a square is decreased in length by 1 foot, its area is 8 ft^2. The length of a side of the square is 1 + 2√2.
Delvig [45]

Let us assume for starters that it is true.

The area of the square is s^2, so that is where you start.

(1 + 2*sqrt(2) ) ^2 = 1 + 4*sqrt(2) + 8 Taking 1 away form that does not leave you with 8.

Let's start again.

If all sides are reduced by 1 , but the square is retained, then the length of the side is 2sqrt(2). Now we have

s^2 = (2sqrt(2) )^2 = 4 * 2 = 8

The question is really not worded clearly enough to give an answer. I think it's true, but the language has to be twisted a bit.

Answer: I'd answer true, but don't be surprised if it is not interpreted the way I did on my second try.

If P(A) = 1/6 , P(B) = 5/12, and P(A\B) + P(B\A) = 7/10 Find P(AUB)
Nesterboy [21]

Probability is the likelihood or chance that an event will occur. The probability of P(AUB) is 1/2

<h3>Conditional probability</h3>

Probability is the likelihood or chance that an event will occur. Given the following parameters

If P(A) = 1/6

P(B) = 5/12

P(A\B) + P(B\A) = 7/10

Required

p(AUB)

Recall that:

P(A|B)=P(AnB)/P(B)

P(B|A) = P(BnA)/P(A)

P(AnB)/P(B) + P(BnA)/P(A) = 7/10
12/5P(AnB) + 6P(BnA) = 7/10

42/5P(BnA) = 7/10
6/5P(BnA) = 1/10
6P(BnA) = 1/2
P(BnA) = 1/12

<u>Determine P(AUB)</u>

P(AUB) = P(A) + P(B) - P(AnB)
P(AUB) = 1/6 + 5/12 - 1/12
P(AUB) = 1/6 + 4/12
P(AUB) = 2+4/12
P(AUB) = 1/2

Hence the probability of P(AUB) is 1/2
