8090 [49]

Answer:

Step-by-step explanation:

a) Standard deviation of 10 mean the fluctuation for values range from +10 to -10 from the mean.

b) Since the sixth student is 50 minutes, which is higher than the mean of 45 minutes, this will bring the over all mean higher that 45 minutes. Also, since 50 falls within the standard deviation range (35 to 55), this mean the new standard deviation will be smaller than 10.

Write 3a^2 b^2 c^5 / 8x^4 y^3 z using no denominator

pantera1 [17]

Currently the denominator is $8x^4y^3z$ . If you want to move those up so they sit with the numerator, then what you have to do is make the exponents negative. You make a negative exponent positive by moving it under a 1; undo that process to make the exponents negative. If we do that, then the expression would be $3a^2b^2c^58 ^{-1} x ^{-4} y ^{-3} z ^{-1}$

General Formulas and Concepts:

Algebra I

Range is the set of y-values that are outputted by function f(x)

Step-by-step explanation:

When we graph the equation, we should see that our y-values span from -∞ to 0. Since 0 is a closed dot, it is inclusive in the range:

(-∞, 0] or y ≤ 0
