The best answer is D.

According to the pythagorean theorem, a^2+b^2=c^2 in a right triangle where a and b are the legs and c is the hypotenuse.

The diagram given gives the length of both legs, so plug it into the equation to get c^2= 24^2+45^2

Find the equation of the line passing through the points 1,-5) and (9,11). y = 2x + [?]

Naily [24]

Answer:

y = 2x - 7

Step-by-step explanation:

Looks like we already have the slope of this line: It is 2. Working with the point (1, -5), we have x = 1 and y = -5 and can from this info easily find the y-intercept, b:

y = mx + b becomes

y = 2x + b, which in turn becomes

-5 = 2(1) + b, or

b = -7,

and so the desired equation is y = 2x - 7

Ostrovityanka [42]

The right answer for the question that is being asked and shown above is that: "e.Events A and B are dependent because P(A|B) = P(A)." The probability that a sample contains protein, given that albumin is detected, is 1. The statement that is true is this events A and B are dependent because P(A|B) = P(A).

Darin can purchase tile at a store for 0.79 per tile and rent a tile saw for $24. At another store, he can borrow the tile saw f

ankoles [38]

Let us denote the number of tiles by $T$ .

In the first store, if Darin bought $T$ tiles, he would need to spend:
                        $0.79\times T+24$ (measured in $)

In the second store, if Darin bought $T$ tiles, he would need to spend:
                        $1.19\times T$ (measured in $)

For the cost to be the same at both stores, it means (measured in $)
                                           $1.19T=0.79T+24$

Moving $0.79T$ over to the left hand side and changing signs:
                                            $1.19T-0.79T=24$
                                            $0.4T=24$
                                            $T= \frac{24}{0.4}$
                                            $T=60$ tiles

Let's check. If he buys 60 tiles in the first store, he spends:
      $0.79×60 + $24 = $47.40 + $24 = $71.40

If he buys 60 tiles in the second store, he spends:
                               $1.19×60 = $71.40

∴ Darin needs to buy 60 tiles for the cost to be the same at both stores.
