Answer:

The probability is 0.8944

Step-by-step explanation:

The probability of Z<1.25 in a normal distribution is

P(Z<1.25) = 0.5 + P(Z<1.25)

P(Z<1.25) = 0.5 + 0.3944

P(Z<1.25) = 0.8944

Hence, the probability of randomly selecting a z-score less than z = 1.25 from a normal distribution is 0.8944

10. JKLM is a rhombus KLN is a triangle. Find MKN.

rjkz [21]

Answer:

65°

Step-by-step explanation:

JM = JK (all sides of a rhombus are equal)

Angle JKM = 25° (isosceles triangle)

Angle JKL = 50° (consecutive angles of rhombus)

Angle MKL = 25° (angle subtraction)

Angle MLK = 130° (opposite angles of a rhombus)

Angle KLN = 50° (angles on a straight line)

Angle LKN = 40° (angle sum of triangle)

Angle MKN = 65° (angle addition)
