Given that t<span>he
mean lifespan of a sylvania light bulb is 1600 hours with a standard
deviation of 300 hours, an iqr of 450 hours, and a range of 690 hours.
the lifespan distribution is relatively symmetric.
Since, the distribution is relatively symmetric, the measure of
spread that is the best measurement is the standard deviation.</span>
(x)(10+x)=96
(x-6)(x+16)=0
x=6,-16
negative can't be an answer this the answer is 6+10= 16 ft

Answer:
h(f(x)) = x
Step-by-step explanation:
Since the functions are inverses h(x) undoes f(x)
That is if f(x) = x then inverse function maps back to x
h(f(x)) = x
Answer:
252
Step-by-step explanation:
The number of integers from 100 to 999 is 999 - 100 +1 = 900.
Consider the number of three-digit integers that <em>do not contain 4 </em>as a digit.
For the <em>hundreds</em> digit, there are 8 possible choices (excluding 0 and 4).
For the <em>tens digit</em>, there are 9 possible choices (excluding 4).
For the <em>ones</em> <em>digit,</em> there are 9 possible choices (excluding 4)
Thus, there are 8 × 9 × 9 = 648 three-digit integers without a 4.
The number of three-digit integers with at least one 4 is 900 - 648 = 252.
