Answer:
Step-by-step explanation:
Sample size 52 card
Pay for J or Q 
Pay for King or Ace 
Pay for others 
Therefore
Probability of drawing J or Q
Probability or drawing King or Ace
Probability or drawing Other cards
Therefore
Expected Gain is mathematically given as

Answer:
(-6, 2) and (-7, -1) and (0, 0)
-------------------------------------------------
Explanation:
You reflected the triangle. You needed to translate the triangle.
y + 6 is to move up 6 units along the y-axis.
x - 5 is to move left 5 units along the x-axis.
Another thing, the question doesn't state was transformation to use so we are going to assume we are translating.

Hope This Helped! Good Luck!
If 1 inch is .25 miles then all you have to do is multiply .25 miles by 5 inches and u get 1.25 miles.
Μ = (0×0.026) + (1×0.072) +(2×0.152) + (3×0.303) + (4×0.215) + (5×0.164) + (6×0.066)
μ = 0 + 0.072 + 0.304 + 0.909 + 0.86 + 0.82 + 0.396
μ = 3.361 ≈ 3.4
We need the value of ∑X² to work out the variance
∑X² = (0²×0.026) + (1²×0.072) + (2²×0.152) + (3²×0.303) + (4²×0.215) + (5²×0.164) + (6²×0.066)
∑X² = 0+0.072+0.608+2.727+3.44+4.1+2.376
∑X² = 13.323
Variance = ∑X² - μ²
Variance = 13.323 - (3.4)² = 1.763 ≈ 2
Standard Deviation = √Variance = √1.8 = 1.3416... ≈ 1.4
The correct answer related to the value of mean and standard deviation is the option D
