Answer:
The value of x is - 11
Step-by-step explanation:
Given as :
∠ M = (5x +90) °
∠ R = 55°
The sum of measure of angle M and R are complementary
Complementary Angle are those when sum of two angle equal to 90°
∵ Angle M and R are complementary in nature
∴ ∠ M + ∠ R = 90°
Or, (5x +90) ° + 55° = 90°
Or, 5x = 90° - 90° - 55°
Or, 5x = - 55°
∴ x = - = - 11
Hence the value of x is - 11 Answer
Answer:
Between (-0.675, 0.675)
Step-by-step explanation:
We know that a standard normal distribution curve is bell shaped unimodal , symmetrical about mean.
for thsi standard normal variate with notation z, we get mean =0 and std deviation = 1
For the middle shaded region, we find z such that the area between -z and z is 0.50 exactly half.
From standard normal distribution table, we get that z= ±0.675
Hence between z=-0.675 and z = 0.675 we get the middle region with area equal to exactly 1/2.
Between (-0.675, 0.675)
