3 0

Answer:

D) Of the 4 people who have a sister, 1 of them also has  a brother.

Step-by-step explanation:

P(B/A) indicates the probability of event B when event A has alredy occured.

Event A = The person has a sister.

Event B = The person has a brother.

So now P(B/A) means the probability of the person having sister who already have brother.

Hence choice "D) Of the 4 people who have a sister, 1 of them also has  a brother." is correct.

Which equation is the slope-intercept form of the line that passes through (6, –11) and is parallel to the graph of y = –2/3x +
IRINA_888 [86]

Answer:

<h2>The answer is option A</h2>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

From the question the original line is

y = - ⅔x + 12

Comparing with the general equation above

Slope = -⅔

Since the lines are parallel their slope are also the same

Slope of parallel line = - ⅔

The equation of the line using point

(6, –11) and slope - ⅔ is

y + 11 =  -  \frac{2}{3} (x - 6) \\ y + 11 =  -  \frac{2}{3} x + 4 \\ y =  -  \frac{2}{3} x + 4  - 11

We have the final answer as

y =  -  \frac{2}{ 3 } x  - 7 \\

Hope this helps you

What is the value of x?<br><br> 27(x+4)=−6<br><br><br> −35<br><br> −25<br><br> 25<br><br> 35
Oksanka [162]

x = -38/9 !!!


27(x+4)=−6

Step 1: Simplify both sides of the equation.

27(x+4)=−6

(27)(x)+(27)(4)=−6 (Distribute)

27x+108=−6

Step 2: Subtract 108 from both sides.

27x+108−108=−6−108

27x=−114

Step 3: Divide both sides by 27.

27x/27=−114/27

x=−389

You borrow $1000 at 6% simple interest for a year how much do you have to pay back?
Rainbow [258]

Answer:150

Step-by-step explanation:

So every year the interest will be $1000 * 5 / 100 = $50. That is, after 3 years 3 * $50 = $ 150. Simple interest does not take into account the reduction of the principal but calculates the interest over the same initial amount, in this case $1000. So, the answer is $150, which is the result of $50 times 3.
