Answer:
C. (x + 2, Y - 3)
Step-by-step explanation:
C. (x + 2, Y - 3)
Answer:
1/2, 50%
Step-by-step explanation:
A cube has six sides. The probability of landing on a number less than four is 3/6 because there are 3 positive numbers less than 4. 3/6=1/2=50%
Hope this helps!

Answer: the probability that a randomly selected Canadian baby is a large baby is 0.19
Step-by-step explanation:
Since the birth weights of babies born in Canada is assumed to be normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = birth weights of babies
µ = mean weight
σ = standard deviation
From the information given,
µ = 3500 grams
σ = 560 grams
We want to find the probability or that a randomly selected Canadian baby is a large baby(weighs more than 4000 grams). It is expressed as
P(x > 4000) = 1 - P(x ≤ 4000)
For x = 4000,
z = (4000 - 3500)/560 = 0.89
Looking at the normal distribution table, the probability corresponding to the z score is 0.81
P(x > 4000) = 1 - 0.81 = 0.19
Answer:
The ordered pair is a solution.
Step-by-step explanation:
Plug x = -3 and y = 0 into the 2 inequalities and see if they fit:
-2x + 2y >= 4
-2(-3) + 2(0) = 6 which is > 4 so this one fits.
y>= 2x - 6
0 >= 2*-3) - 6 = -12 which also fits.
