If repeated samples of yogurt sales were taken, according to the Central Limit Theorem, the mean of those repeated samples would tend to be normally distributed if the sample size is large enough. For most distributions, a sample size of or more satisfies the requirements of the Central Limit Theorem.

1.  line AB ≅ line CD (its congruent)

2. m<ZXY - m<WXZ = m<WXY

Step-by-step explanation:

1.

A (-3, 2)

B (0, 3)

C (-1, 2)

D (2, -3)

find:

determine if AB ≅ CD (congruent or non-congruent)

solution:

Length AB = √(0+3)² + (3+2)² = 5.8

Length CD = √(2+1)² + (-3-2)² = 5.8

therefore,

line AB ≅ line CD (its congruent)

2.

m<ZXY - m<WXZ = m<WXY

given:

point Z is in the interior of <WXY creating XZ.

if m<WXZ = 20

m<WXY = 100

find:

what would equation would you set up to find the missing angle measure?

solution:

Since Z is interior of <WXY

m<ZXY - m<WXZ = m<WXY

<WXY = 100 - 20 = 80°

therefore, the equation would be m<ZXY - m<WXZ = m<WXY
