Answer:

  55 gallons, the initial quantity of water in the tank

Step-by-step explanation:

Y is defined as the amount of water in the tank. When X (the number of minutes spent draining) is zero, no water has left the tank. So, the Y-intercept is the initial amount of water in the tank, 55 gallons.

23) m 2 = 7x + 6<br>70°​
lakkis [162]

Answer:

∠2 = 55°

Step-by-step explanation:

Given that the triangle has 2 congruent sides then the triangle is isosceles.

Thus the 2 base angle are congruent, both equal to ∠2

The sum of the 3 angles in a triangle = 180

7x + 6 + 7x + 6 + 70 = 180, that is

14x + 82 = 180 ( subtract 82 from both sides )

14x = 98 ( divide both sides by 14 )

x = 7

Hence

∠2 = 7x + 6 = (7 × 7) + 6 = 49 + 6 = 55°

Find the probability of at least 2 girls in births. Assume that male and female births are equally likely and that the births ar
tiny-mole [99]
We assume that male and female births are equally likely, it means that the probability of birth of male= probability of birth of female = 100%/2=50% or 0.5We have 2 independent events. So what will be the variants:
Male and FemaleMale  and Male Female and Male Female and Female 
All four variants are equally likely.Probability of each one is 1/4 = 0.25.So, Result "Female and Female"
 are probability = 0.250 --- if round to three decimal places.
