Answer:
there are 97 + 47 + 77 = 221 creatures from Earth in the alien spaceship.
the probability that a human being is chosen at random = 77 / 221 = 0.3484 = 34.84%
the probability that a chicken is chosen at random = 97 / 221 = 0.4389 = 43.89%
the probability of choosing a cow at random = 100% - 34.84% - 43.89% = 21.27%
Answer:For this item, we let x and y be the number of bushels of apple that will be used to produce apple cider and apple juice, respectively. The situation above is best represented by the following equations,
x + y = 18
20x + 15y = 330
The values of x and y from the equations above are 12 and 6, respectively. Therefore, 12 bushels will be used to make apple cider and 6 bushels will be used to make apple juice.
Step-by-step explanation:
Oh my goodness . . .
What do you get when you multiply a number by itself ?
Do you get the square of the number ?
And what do you get when you square the square root of a number ?
Is it the number inside the square root ?
For just a second, let's take the quantity (4t - 3) and call it ' Q '.
Then the problem is to multiply
√Q times √Q .
Isn't that just ' Q ' ?
And is this enough help ?
