Answer:

2/11

Step-by-step explanation:

We have to calculate this by

p(B nA)/p(A)

= We have A¹ to be that none of the die roll gives us 6

P(A¹) = 5/6²

P(A) = 1 -5/6²

= 11/36

BnA = one die being 6 and summation being equal to 8

= BnA = (6,2)(2,6)

= P(BnA) = 2/36

Therefore we have (2/36)/(11/36)

= 2/11

Two possible floor plans for a new bathroom are shown.
Neko [114]

Answer:

Hope it works for u

Step-by-step explanation:

As we have given two shapes bathroom

square and rectangle

Parameter of square= sum of all the sides   ( : In square all sides are equal

Parameter of square= 4*L  = 4*(x+3)       (:L=x+3

similarly,

In rectangle opposites sides  are equal hence

Perimeter of rectangle= 2*length+2*width  ( : length=x+4,width can't be seen clearly so I assume and take it width=x+1  hope this is equal to the width of ur question otherwise do the calculation by ur self).

Perimeter of rectangle= 2*(x+4)+2(x+1)

so now we have to find the value of "x" for which both perimeter are equal, so

perimeter of square= perimeter of rectangle

4*(x+3)=2*(x+4)+2(x+1)  we can also write as

<h2>2(x+3)+2(x+3)=2(x+4)+2(x+1)</h2><h3>This is the linear equation required</h3><h3>now to find value of "x"</h3><h3>simplify both sides, we get</h3><h3>4x+12=4x+10</h3><h2>0≠2 so that not true and also there is no value of "x"</h2>

for which both parameters become equal

<h2>so from my side "b" option is correct</h2>

Please brain-list it if u find it help-full it requires effort!

A = base side=3

b= base side=5

c = base side=3

h= height=7-4=3

l= lenght=6

w= width=5

h= height=4

V= 1/4h√(-a⁴+2(ab)²+2(ac)²-b⁴+2(bc)²-c⁴) + l w h 

V=12.44+ 120=132.44 unit³

Find the equation of a line given the point and slope below. Arrange your answer in the form y = mx + b, where b is the constant
Dvinal [7]

Answer:

y = 2x + 1

Step-by-step explanation:

Given a point and the slope, we can plug in these values into the equation to find the value of b:

y = mx + b

3 = 2(1) + b

3 = 2 + b

1 = b

Plug b into the equation:

y = 2x + 1
