The given expression for the area, 81x² - 4y², is a difference of two squares. The first term is the square of 9x and the second term is the square of 2y. The factors of this difference and the therefore the dimensions of the rectangle are, 9x - 2y and 9x + 2y.

juin [17]

Answer:

Since this season, the probability that the Yankees will win a game is 0.6 The probability that the Yankees will lose when they score 5 or more runs is 19.2%.

Step-by-step explanation:

Since this season, the probability that the Yankees will win a game is 0.6 and the probability that the Yankees will score 5 or more runs in a game is 0.48, and he probability that the Yankees lose and score fewer than 5 runs is 0.33, To determine what is the probability that the Yankees will lose when they score 5 or more runs, the following calculation must be performed:

(1 - 0.6) x 0.48 = X

0.40 x 0.48 = X

0.192 = X

0.192 x 100 = 19.2

Therefore, the probability that the Yankees will lose when they score 5 or more runs is 19.2%.

Answer:

Step-by-step explanation:

This problem is just really long- it's trying to confuse you with complicated wording. Here's it demystified:

a)

t = 0 degrees Celsius

d = 1500 meters

Find the temperature, T.

b)

d = 300 meters

T = 26 degrees Celsius

Find the ground temperature, t.

NOTE: The temperatures are different! T is the final temperature and t is the ground temperature.

Solve for m. -19m − 19 = 4m − 4m + 19
dangina [55]
-19m-19 = 4m-4m+19
-19m-19 = 0+19
-19m = 19+19
-19m = 38
m = 38÷(-19)
m = -2
