6.4/8 = y/6 = x/7

0.8/1 = 4.8/6 = 5.6/7

6.4/8 = 4.8/6 = 5.6/7

x = 5.6 ; y = 4.8

I think that’s how you do it but not 100% sure

Describe what the notation Upper P (Upper B vertical line Upper A )represents.

sergey [27]

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

Upper P (Upper B vertical line Upper A)

means

$P(B|A)$

It means that probability of getting event B given that Event A is occurred.

D. The probability of event B occurring, given that event A has already occurred. is also expressed as $P(B|A)$

Hence, Option 'D' is correct.

Answer:

$x=2\sqrt{5}$

Step-by-step explanation:

If that is a square, then all sides are the same. Therefore, it's a $\sqrt{10}$ by $\sqrt{10}$ shape. We'll use Pythagorean Theorem to find the diagonal.

$a^2+b^2=c^2\\\sqrt{10}^2+ \sqrt{10}^2=x^2\\10+10=x^2\\20=x^2\\\sqrt{20}=x\\\sqrt{4*5}=x\\ 2\sqrt{5}=x$

Since it's not a fraction, there is no denominator to rationalize. Let me know if you have any other questions!

Answer: 78.5 units^2

Step-by-step explanation:

The area of the circle is equal to pi*radius^2.

The diameter is double the radius, which means the radius is 10/2 = 5.

Therefore, the area is pi*5^2 = 25pi.

We use 3.14 for pi and we get 25*3.14 = 78.5 units^2
