Answer:
the diagonals of a rectangle are equal in
in length so. LN=MP
13x -10=9x+9
13x-9x=9+10
4x=19
x=19/4
Answer: 0.0228 .
Step-by-step explanation:
Given, IQ scores are approximately normally distributed with a mean of 100 and standard deviation of 15
Let X denotes the IQ score.
Then, the proportion of people with IQs above 130 is
Hence, the proportion of people with IQs above 130 is 0.0228 .
Answer:
(x + 1)² = (2x)²
(1 + 1)² = (2(1))²
2² = 2²
4 = 4
(-1 + 1)² = (2(-13))²
(-12)² = (-26)²
Not true
x = -13 satisfies neither
4. is proportional because it is 30x
