It’s a variable because when you justo I can’t stay the same every time it changes
Answer:
300
Step-by-step explanation:
To find how many carrots, determine how many square units by finding the area. You can calculate the area by finding the area of the inside square 4 by 4 and then adding the area of each triangle on the side.
Area of square = 4*4 = 16 square units
Area of 2 triangles = 2(2*2*1/2)= 2(2) = 4 square units
16+4 = 20 square units.
15 carrots come from 1 square units so 15(20) = 300 carrots
Answer:
Step-by-step explanation:
Si haces una fracción buscando su denominador te da resultados
union=( -2,-1,0,1,2,5,7,8) intersection= -1,1
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
