P(<br> b.=15/16,p(a and <br> b.=3/4 find p(a

Bess [88]

And or both means we multiply the given probability situations that are mutually exclusive and exhaustive - they cannot occur at the same time.

let P(a)=x

then: P(b) * P(a) =3/4

         15/16 * x = 3/4

          15x/16 = 3/4
therefore x= 3/4 *16/15
          x = 4/5
P(a) = 4/5

hope it's clear

Find the equation of the perpendicular bisector of a line segment whose end points are (-3,9) and (-1,5)

timofeeve [1]

First find the equation of y.

$y=mx+n=\frac{\Delta y}{\Delta x}x+n$

Find the slope m.

$m=\frac{5-9}{-1-3}=\frac{-4}{-4}=1$ .

Pick one point, I'll pick (-3, 9). Insert coordinates in equation then compute n.

$9=1(-3)+n\implies n=12$ .

The equation of a line y is:

$y=x+12$ .

The perpendicular line $y_{\perp}$ is same like the normal line except its slope m becomes:

$k=-\frac{1}{m}=-1$ .

The equation of a perpendicular bisector is thus:

$y_{\perp}=-x+12$ .

Hope this helps.

ANSWER ASAP PLEASE RIGHT ANSWER GETS BRAINLIST

Natasha_Volkova [10]

Answer:

Step-by-step explanation:

We can set up equation for this one.

Let's say the number is X.

the sum of X and 14 can be expressed as : X+14

five times the sum of X and 14 can be expressed as 5(x+14)

and 5(X+14) = 80

$5(x+14) = 80\\x+14 = 80 \div 5 = 16\\x = 16-14 = 2$

The number is 2

if $5,000,000 isinvested at 4% interest compunded continuously, how much willl the investment be worth in 30 years

Katarina [22]

The answer is $16216987.55 (IMPORTANT: This is the answer assuming that the interest rate is annually. The quesiton says 'continuously' so I was a bit confused)

To solve this problem, you can use the compound interest formula.

Here it is once you plug in the numbers: A = 5,000,000 ( 1 + .04) ^30

Just solve the equation to find the solution.
