<h2>Answer:</h2>

The probability of A and B is:

                 P(A\ and\ B)=0.08

<h2>Step-by-step explanation:</h2>

We know that when two events: Event A and event B are independent then if P denote the probability of an event then Probability A and B is equal to the product of probability of the individual events.

i.e.

P(A\ and\ B)=P(A)\times P(B)

Here we have:

P(A) = 0.80 and P(B) = 0.10

Hence,

P(A\ and\ B)=0.80\times 0.10\\\\P(A\ and\ B)=0.08

Can someone help me with this problem ​
Alex_Xolod [135]

Answer:

<h2>A = 20</h2><h2>P = 6√10</h2>

Step-by-step explanation:

The formula of a distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

A(-3, 0) , B(3, 2)

AB=\sqrt{(3-(-3))^2+(2-0)^2}=\sqrt{6^2+2^2}=\sqrt{36+4}=\sqrt{40}=\sqrt{4\cdot10}=\sqrt4\cdot\sqrt{10}=2\sqrt{10}

A(-3, 0), D(-2, -3)

AD=\sqrt{(-2-(-3))^2+(-3-0)^2}=\sqrt{1^2+(-3)^2}=\sqrt{1+9}=\sqrt{10}

AB = CD and AD = BC

The area of a rectangle:

A=(AB)(AD)

Substitute:

A=(2\sqrt{10})(\sqrt{10})=(2)(10)=20

The perimeter of a rectangle:

P=2(AB+AD)

Substitute:

P=2(2\sqrt{10}+\sqrt{10})=2(3\sqrt{10})=6\sqrt{10}

Help is it A or B? pls help
Damm [24]

Answer:

f(x)=-(x+8)(x-2)

Step-by-step explanation:

Start by factoring out a -1...

f(x)=-(x^2+6x-16)

Now, we have to find two integers that multiply to get -16 and have a sum of 6:

(-2)*8=-16

-2+8=8-2=6

Using this, we can split 6x into -2x and 8x...

f(x)=-(x^2-2x+8x+16)

Factor  the first and second half separately...

f(x)=-[(x^2-2x)+(8x-16)]\\f(x)=-[x(x-2)+8(x-2)]\\

Since both x and 8 are being multiplied by x-2, we can combine them to get...

f(x)=-(x+8)(x-2)

Nicole rented a bike from Krystal's Bikes. It costs $15 plus $7 per hour. If Nicole paid $43, then she rented the bike for how m
murzikaleks [220]

Given that Nicole rented a bike from Krystal's Bikes, the number of hours is

4 hours

Given data

Initial Cost  = $15

Cost per extra hours = $7

Amount Paid = $43

The Expression that we will use to describe this situation is modelled below

let y = Amount paid

    m = cost per extra hour

    x = the number of hours

   c = the initial cost

y = mx + c -------- Equation of line

43 = 7*x + 15

43 = 7x+15

7x = 43-15

7x = 28

divide both sides by 7

x= 28/7

x= 4 hours

Hence the number of hours is 4 hours
