Answer:

50-2.5t=w. no, the water will all have drained by then.

Step-by-step explanation:

2.5 per min so

min=t

therefore 2.5t

theres 50 quarts of water

50-2.5t = w (water left in the tank)

_____________________________________-

part 2,

2.5*30 = 75, and 50<75

this is impossible.

Please help me with this math problem

elena55 [62]

When a tangent line (13.5 cm) and a secant (lines x + 8.45 cm) intersect then:

tangent line^2 = 8.45 * (8.45 + x)

13.5^2 = 71.4025 + 8.45 x

182.25 -71.4025 = 8.45x

8.45 x = 110.8475

x = 13.1180473373

x = 13.1 (rounded)

Geometry question Please help answer

Bess [88]

Answer:

Step-by-step explanation:

m∠1 = 2x and m∠2 = -3x+235

angle 1 and angle 2 are supplementary angle so they add up to 180°

m∠1 +m∠2 = 180°

2x -3x+235 = 180°

-x = 180-235

x=35

m∠1 = 2x = 2*35 = 70°

m∠2 = -3x+235 = -3*35 +235 = 235-105 = 130°

In a certain liberal arts college with about 10,000 students, 50% are males. If two students from this college are selected at r

Law Incorporation [45]

Answer:

The probability that both the students selected are of the same gender is 0.25.

Step-by-step explanation:

Let X = number of students selected of the same gender.

The probability of selecting a student of a particular gender is,

P (X) = p = 0.50.

The number of students selected is, n = 2.

The random variable follows a Binomial distribution.

The probability of a binomial distribution is computed using the formula:

$P(X=x)={n\choose x}p^{x}(1-p)^{n-x};\ x=0,1,2,3,...$

Compute the probability that both the students selected are of the same gender as follows:

P (Both boys) = P (Both girls) = P (X = 2)

$={2\choose 2}(0.50)^{2}(1-0.50)^{2-2}\\=1\times 0.25\times1\\=0.25$

Thus, the probability that both the students selected are of the same gender is 0.25.
