Answer:
The probability mass function of random variable X which represents the number of blue marbles drawn in 2 draws with replacement.
X | P(X)
0 | 0.390625
1 | 0.46875
2 | 0.140625
The probability of drawing exactly one blue marble = 0.46875
0.46875 as a simplified fraction is ------ 15/32
Step-by-step explanation:
Answer:
-3
Step-by-step explanation
If s(t) is equal to -9 - 3t, its derivative is equal to -3 for all values of t. The instantaneous velocity is simply the derivative at that point, so it is -3.
Answer:
6.08 kg bag unit price: $1.72
7.48 kg bag unit price: $1.86
6.08 kg bag is the better buy
Step-by-step explanation:
To find unit price, divide the price by the amount. 10.47 divided 6.08 equals 1.7203947. Round it to the nearest cent to get 1.72. So, the unit price for the first bag is $1.72. Next divide 13.88/7.48 to get 1.85561. Round it to the nearest cent to get 1.86. So, the unit price for the second bag is $1.86 per kg. The better buy is the cheaper one, so the 6.08 kg bag is a better deal. Hope this helped!
