Answer:
-5 ≤ x < 0
Step-by-step explanation:
Step 1: Convert word signs to math
greater than or equal to: ≤ x
less than: x <
Step 2: Substitute in numbers
-5 ≤ x < 0
The percent change between the temperature at noon and the temperature at 5:00 p.m. is -20%
The percent change is the relative change between two quantities expressed in percentage.
Given that the At noon, the temperature was 80°F while At 5:00 p.m., the temperature was 64°F. Hence:
Percent change = [(64°F - 80°F) / 80°F] * 100%
Percent change = -20%
Therefore the percent change between the temperature at noon and the temperature at 5:00 p.m. is -20%

Answer:
The proportion of scores reported as 1600 is 0.0032
Step-by-step explanation:
Let X be the score for 1 random person in SAT combining maths and reading. X has distribution approximately N(μ = 1011,σ = 216).
In order to make computations, we standarize X to obtain a random variable W with distribution approximately N(0,1)
The values of the cummulative distribution function of the standard Normal random variable, lets denote it are tabulated, you can find those values in the attached file. Now, we are ready to compute the probability of X being bigger than 1600
Hence, the proportion of scores reported as 1600 is 0.0032.
