Select all the properties that must be true of a normal distribution. a
The distribution has a height of zero when it is more than 3 standard deviations away from the center.
b
The area under the normal distribution curve and within 2 standard deviations of the center is about 95% of the total area under the curve.
c
The distribution is bell-shaped.
d
The total area under the normal distribution curve is 1.
e
The distribution is centered at the mean absolute deviation.
f
The distribution is determined by the mean and standard deviation.
Question 2 (1 point)

13.33%

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
