Answer: 0.866
Step-by-step explanation:
Mean = 4022
SD = 266
We are looking for the probability of samples 45g differ than the mean. Hence 2 probability combination:
X>4067 and X<3977
Calculate for Z we'll get Z = 0.16917 and -0.161917
Using Z formula we can find P(Z=0.17) = 0.433
Since both probability will occupy the same area, total probability is 0.433x2 = 0.866
<span>8x = 2y + 5
3x = y + 7 so y = 3x - 7
substitive </span>y = 3x - 7 into 8x = 2y + 5
8x = 2y + 5
8x = 2(3x - 7) + 5
8x = 6x - 14 +5
2x = -9
x = -4.5
y = 3x - 7
y = 3(-4.5) - 7 = -13.5 - 7 = -20.5
solutions (-4.5, -20.5)
Answer:
V = 15 pi ft^3
Step-by-step explanation:
The volume of a cone is given by the formula
V=1/3 pi r^2 h
We know the radius and the height
V = 1/3 pi *(3)^2*5
V = 1/3 *pi*9*5
V = 15 * pi
Leave in terms of pi
V = 15 pi ft^3
No, 200 centimeters is greater than 2 yards
For the first the correct answer is C
the second
the perimiter of the triangle is equal the sum of the sides
x +x-1+x-2= 12
3x = 12 +3
x= 15/3 = 5
